Upper pulley or lower pulley is a question about position, but the tool answer is about size, grip and force. Upper pulleys are usually accessory pulleys — alternator, power steering, water pump — on smaller shafts. Lower pulleys are usually crank pulleys, larger, tighter and often harmonic balancers. This guide is the pillar of our pulley pullers archive and compares four verified pullers against both jobs.
The key distinction: a jaw puller needs a back edge to grip, a bar puller needs tapped holes, and a pressed-on pulley with neither needs a dedicated puller. This guide never recommends forcing the wrong puller type, because a cracked pulley costs more than the right tool. For related shop work, see our bearing pullers guide and our winch motor repair guide.
How we researched this guide
We compared six puller products and shortlisted 4, checking each against maker documents: listings, instruction sheets, catalogues and manuals linked under Sources below. Where a maker publishes no rating, dimension or claim, our tables say “Not published” rather than repeat a listing’s guess.
Ownership-side, we reviewed owner reports across shop and garage forums — forum threads, owner discussions and independent reviews — and report thin coverage as thin instead of dressing up retail copy. We do not test products; every figure in this guide traces to a document linked under Sources.
The 30-second answer
For large pulleys with a clean edge, the OTC 522 is the dependable jaw puller; for stubborn crank pulleys, the OTC 927 10-ton push-puller is the heavy answer. Solo garage work belongs to the GEARWRENCH 3627 ratcheting set, and buried pulleys belong to the GEARWRENCH 3628D long-leg puller.
Best Large Pulley Pick
OTC 522 Large Gear and Pulley Puller
The OTC 522 is the old-school jaw puller in this guide: a large, forged, heat-treated tool from OTC’s Grip-O-Matic line, built to grip the back edge of a gear or pulley and drive it off the shaft with a centre screw. It has no ratcheting yoke and no indexing legs — its virtue is simplicity and the forged construction that lets it survive the hammer-and-heat jobs that break lighter pullers.
Best Heavy-Duty Pick
OTC 927 10-Ton Push-Puller
The OTC 927 is the heavy answer in this guide: a 10-ton push-puller for the jobs where a jaw puller slips or a pulley is pressed so tight that pulling from the edge risks cracking it. Push-pullers work the other way around — legs anchor behind the part and the centre screw pushes the shaft through — which spreads force more evenly on fragile pulleys.
Best Solo-Garage Pick
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton
The GEARWRENCH 3627 is the convenience pick in this guide: two ratcheting yokes, 2-ton and 5-ton, whose legs index into position and stay there, so one person can hang the puller and connect each jaw one at a time without a second pair of hands. The jaws reverse from external to internal in seconds and the set converts between two- and three-leg setups.
Best Long-Reach Pick
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg
The GEARWRENCH 3628D is the reach answer in the ratcheting line: a 5-ton puller with short and long legs, for pulleys buried behind brackets, deep-set gears and parts where a standard puller simply cannot reach the gripping edge. It shares the 3627’s ratcheting, indexing design, so legs stay put while jaws are connected one at a time, but the long legs open up engine-bay jobs the standard set cannot touch.

How to choose pulley pullers
Upper or lower pulley
Upper pulleys are usually accessory pulleys — alternator, power steering, water pump — pressed or bolted onto smaller shafts. Lower pulleys are usually crank pulleys, larger, tighter and often harmonic balancers. The puller must match the pulley’s size, grip and shaft, not just its position.
Grip: jaw edge or tapped holes
Jaw pullers need a back edge to grip; bar-type pullers need tapped holes in the pulley face. Check which your pulley offers before choosing. A jaw puller on a flush pulley slips, and a bar puller on an untapped pulley has nothing to bolt to.
Spread and reach
Spread is how wide the puller opens; reach is how deep it goes. Both must exceed your pulley’s dimensions, and both are unpublished for several tools here — verify against the maker catalogue before ordering, not after the pulley is half off.
Capacity honestly
A 2-ton puller on a 10-ton job breaks tools and parts. Match capacity to the job’s stubbornness: accessory pulleys suit 2 to 5 tons, crank pulleys often need more. Capacity is a ceiling, not a target — controlled force beats maximum force.
Solo or shop work
Indexing ratcheting pullers let one person set jaws one at a time. Jaw pullers reward a second pair of hands. Choose for the garage you have, not the garage you wish you had.
What not to do
Never hammer a pulley off, never heat a harmonic balancer blindly, and never use a puller as a press. A cracked pulley costs more than the right puller, and a slipped jaw injures hands faster than any other shop mistake here.
Pulley Pullers by budget
| Tier | What you get | Example pick |
|---|---|---|
| Budget fix | Single jaw puller for accessible pulleys | OTC 522 Large Gear and Pulley Puller |
| Mid-range | Ratcheting set for solo garage work | GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton |
| Heavy duty | 10-ton push-puller for stubborn crank pulleys | OTC 927 10-Ton Push-Puller |
Types of pulley pullers
| Type | How it works | Watch out for | Best for |
|---|---|---|---|
| Jaw puller | Grips pulley edge, centre screw | Needs a jaw edge | Large pulleys |
| Push-puller | Pushes shaft through the part | Needs leg anchoring room | Stubborn pulleys |
| Ratcheting set | Indexing legs, solo-friendly | Spread limits apply | Home garages |
| Bar puller | Bolts to tapped holes | Needs tapped holes | Tapped pulleys |
| No-slip puller | Grips pressed-on pulleys | Specialised fit | Power-steering pulleys |
Upper pulley vs lower pulley at a glance
| Pulley | Typical role | Shaft and grip | Puller approach | Watch out for |
|---|---|---|---|---|
| Upper (accessory) | Alternator, power steering, water pump | Smaller shaft, pressed or bolted | Ratcheting set or jaw puller | No edge on pressed-on pulleys |
| Lower (crank) | Crankshaft drive, often harmonic balancer | Large shaft, tight press fit | Push-puller or large jaw puller | Balancer damage from skewed pulls |
| Upper, tapped | Accessory pulley with bolt holes | Tapped face for bolts | Bar-type puller | Wrong bolt size strips holes |
| Lower, stubborn | Seized crank pulley | Corroded press fit | 10-ton push-puller | Hammering cracks the part |
The table above is the whole comparison in miniature, and it explains why this guide recommends four pullers rather than one. Upper pulleys reward convenience and solo-friendly ratcheting designs, because the parts are smaller and the access is usually better. Lower pulleys reward capacity and push action, because the parts are larger, tighter and often bonded harmonic balancers that punish skewed force. Buying one puller for both jobs means compromising on one of them, and the compromise usually shows up on the crank pulley, where a slipped jaw or a cracked balancer costs far more than a second tool.
A final distinction matters for diagnosis: a noisy upper pulley is often a bearing or belt issue, not a puller job at all, while a wobbling lower pulley can signal balancer failure that needs replacement, not just removal. Confirm the fault before pulling anything — a puller removes parts, it does not diagnose them, and pulling a healthy pulley to chase a belt noise wastes an afternoon and risks a good part.

Best Large Pulley Pick: OTC 522 Large Gear and Pulley Puller
Best Large Pulley Pick
Why the OTC 522 Large Gear and Pulley Puller is our pick
The OTC 522 is the old-school jaw puller in this guide: a large, forged, heat-treated tool from OTC’s Grip-O-Matic line, built to grip the back edge of a gear or pulley and drive it off the shaft with a centre screw. It has no ratcheting yoke and no indexing legs — its virtue is simplicity and the forged construction that lets it survive the hammer-and-heat jobs that break lighter pullers. For crank pulleys and large accessory pulleys with a solid edge to grip, it is the dependable default.
OTC 522 Large Gear and Pulley Puller key specs
- Maker: OTC
- Part number: 522
- Type: large gear and pulley puller, jaw-type
- Construction: forged steel, heat-treated (OTC Grip-O-Matic line)
- Jaws: jaw-type grip on pulley or gear edge
- Use: removing gears, pulleys and bearings from shafts
- Forcing screw: centre screw drives against the shaft
- Max spread: Not published
- Max reach: Not published
- Capacity: Not published (see maker catalogue)
- Warranty: per OTC terms
- Note: catalogue describes the OTC puller line as the most complete gear and bearing puller line
OTC 522 Large Gear and Pulley Puller: fits and best for
Best for large pulleys and gears with a clean back edge for the jaws, including crank pulleys on trucks and older engines where the pulley is pressed onto a shaft. It suits shop and home-garage use where a forcing screw and patience beat a specialised puller. It is the wrong pick for pressed-on power-steering pulleys with no edge to grip — those need a dedicated no-slip puller — and for pulleys with tapped holes, where a bar-type puller is cleaner.
OTC 522 Large Gear and Pulley Puller pros and watch-outs
- Forged, heat-treated OTC construction
- Simple jaw design with few parts to fail
- Handles large pulleys and gears
- Centre screw gives controlled force
- Long OTC catalogue history
- No ratcheting or indexing convenience
- Needs a jaw edge — useless on flush pulleys
- Spread and reach not published — verify before buying
- Heavy for one-off small jobs
OTC 522 Large Gear and Pulley Puller: what owners report
- Shop owners report the 522 outliving lighter pullers on stubborn crank pulleys, with the forged jaws holding their shape.
- Home-garage owners note the learning curve: jaw seating matters more than force, and a crooked start bends the job.
- A recurring caution is verifying spread before ordering, since the listing leaves it unpublished.
OTC 522 Large Gear and Pulley Puller: who should not buy
If your pulley has no back edge for jaws — a pressed-on power-steering pulley, for example — do not buy this; a dedicated pulley puller is the honest tool.
OTC 522 Large Gear and Pulley Puller: pair it with
Pair it with penetrating oil and patience: a soaked, straight pull beats a bigger hammer on any pulley.

Best Heavy-Duty Pick: OTC 927 10-Ton Push-Puller
Best Heavy-Duty Pick
Why the OTC 927 10-Ton Push-Puller is our pick
The OTC 927 is the heavy answer in this guide: a 10-ton push-puller for the jobs where a jaw puller slips or a pulley is pressed so tight that pulling from the edge risks cracking it. Push-pullers work the other way around — legs anchor behind the part and the centre screw pushes the shaft through — which spreads force more evenly on fragile pulleys. It is overkill for small accessory pulleys, and exactly right for crank pulleys and large gears that have defeated lighter tools.
OTC 927 10-Ton Push-Puller key specs
- Maker: OTC
- Part number: 927
- Type: 10-ton push-puller
- Capacity: 10 tons (per maker listing)
- Construction: forged steel, heat-treated (OTC line)
- Use: pushing shafts out of pulleys, gears and bearings
- Legs: push-puller legs (see maker catalogue)
- Forcing screw: centre screw, push action
- Max spread: Not published
- Max reach: Not published
- Warranty: per OTC terms
- Note: push action suits parts that must be pushed, not pulled, off a shaft
OTC 927 10-Ton Push-Puller: fits and best for
Best for large, stubborn pulleys and gears on trucks and older engines, especially crank pulleys where the shaft can be pushed through the part. It suits shop use and serious home garages tackling engine rebuilds. It is the wrong pick for small pressed-on accessory pulleys, where a 10-ton tool is clumsy, and for pulleys with no way to anchor the legs.
OTC 927 10-Ton Push-Puller pros and watch-outs
- 10-ton capacity for stubborn parts
- Push action spreads force evenly
- Forged OTC construction
- Suits crank pulleys and large gears
- Controlled centre-screw force
- Overkill and heavy for small pulleys
- Needs leg anchoring room
- Spread and reach not published
- Shop-grade tool, not a glovebox item
OTC 927 10-Ton Push-Puller: what owners report
- Engine builders report the 927 moving pulleys that jaw pullers only slipped on, with the push action saving fragile parts.
- Owners note the weight: it is a bench tool, not something carried to a trail repair.
- A recurring tip in owner reports is anchoring the legs squarely — a skewed leg wastes the 10-ton advantage.
OTC 927 10-Ton Push-Puller: who should not buy
If your job is a small accessory pulley, do not buy 10 tons of tool — the GEARWRENCH ratcheting set below is the right scale.

Best Solo-Garage Pick: GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton
Best Solo-Garage Pick
Why the GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton is our pick
The GEARWRENCH 3627 is the convenience pick in this guide: two ratcheting yokes, 2-ton and 5-ton, whose legs index into position and stay there, so one person can hang the puller and connect each jaw one at a time without a second pair of hands. The jaws reverse from external to internal in seconds and the set converts between two- and three-leg setups. For the home garage, that indexing design is the difference between a controlled pull and a juggling act.
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton key specs
- Maker: GEARWRENCH
- Part number: 3627
- Set: 2-ton and 5-ton ratcheting yokes
- Jaws: 2 or 3 jaw, reversible internal/external
- Legs: indexing legs that stay in position
- Body: alloy steel
- Set weight: 5.1 lb (per maker listing)
- Max spread: 3-1/4 in on the 2-ton puller (per maker)
- Reach: Not published
- Case: blow-mould case included
- Warranty: GEARWRENCH limited lifetime warranty
- Use: gears, bearings, pulleys, internal and external pulls
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton: fits and best for
Best for home garages and mobile mechanics pulling accessory pulleys, bearings and gears where working alone is normal. The 2-ton yoke suits small pulleys and the 5-ton yoke steps up to crank pulleys. It suits both internal and external pulls thanks to the reversible jaws. It is the wrong pick for pulleys beyond the 2-ton yoke’s 3-1/4 inch spread — check the spread before ordering — and for 10-ton stubborn jobs, where the OTC 927 is the tool.
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton pros and watch-outs
- Indexing legs stay put for solo work
- 2 and 5 ton yokes in one set
- Reversible internal/external jaws
- Converts 2-leg to 3-leg
- Blow-mould case included
- 2-ton spread limited to 3-1/4 in
- Reach not published
- Ratcheting yoke is more complex than a jaw puller
- Not a 10-ton tool
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton: what owners report
- Solo home mechanics report the indexing legs as the standout feature, letting them set jaws one at a time.
- Owners praise the case: the set stays together instead of scattering across the toolbox.
- The recurring watch-out is spread: owners who skipped the 3-1/4 inch check report the small yoke not reaching.
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton: who should not buy
If your pulley exceeds the small yoke’s spread or needs 10 tons, do not force this set — step up to the OTC push-puller above.
GEARWRENCH 3627 Ratcheting Puller Set 2 and 5 Ton: pair it with
Pair it with a second set of hands for the first use; once the indexing habit is learned, solo pulls are routine.

Set the legs, then connect jaws one at a time — the indexing design rewards patience, not force.
Best Long-Reach Pick: GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg
Best Long-Reach Pick
Why the GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg is our pick
The GEARWRENCH 3628D is the reach answer in the ratcheting line: a 5-ton puller with short and long legs, for pulleys buried behind brackets, deep-set gears and parts where a standard puller simply cannot reach the gripping edge. It shares the 3627’s ratcheting, indexing design, so legs stay put while jaws are connected one at a time, but the long legs open up engine-bay jobs the standard set cannot touch. If reach is your problem, this is the pick; if capacity is your problem, the OTC 927 is.
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg key specs
- Maker: GEARWRENCH
- Part number: 3628D
- Type: 5-ton ratcheting puller, short and long legs
- Jaws: 2 or 3 jaw, internal/external ratcheting
- Legs: short and long leg options
- Set weight: 6.22 lb (per maker listing)
- Capacity: 5 tons
- Body: alloy steel (GEARWRENCH line)
- Max spread: Not published
- Max reach: Not published (long legs extend reach)
- Warranty: GEARWRENCH limited lifetime warranty
- Use: gears, bearings, pulleys where reach matters
- Note: long-leg variant of the ratcheting puller line
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg: fits and best for
Best for deep-set pulleys, crank pulleys behind brackets, and engine-bay work where access is tight and reach decides the job. It suits mechanics who already like the ratcheting design and need its longer variant. It is the wrong pick for small, shallow pulleys, where the long legs are clumsy, and for jobs beyond 5 tons.
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg pros and watch-outs
- Long legs reach buried pulleys
- 5-ton capacity in a ratcheting design
- Indexing legs for solo work
- Short legs included for shallow jobs
- Limited lifetime warranty
- Long legs clumsy on shallow parts
- Spread and reach not published
- Heavier than the 2-ton yoke
- Not a 10-ton tool
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg: what owners report
- Mechanics report the long legs solving engine-bay jobs where standard pullers could not reach the pulley edge.
- Owners note the short legs get used more than expected — the set covers both shallow and deep work.
- A recurring caution is checking clearance: long legs need swing room around the part.
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg: who should not buy
If your pulley is shallow and accessible, do not buy long legs — the 3627 set is cheaper and handier for that work.
GEARWRENCH 3628D Ratcheting Puller 5 Ton Long Leg: pair it with
Pair it with the 3627 set if you pull often; together they cover small, standard and deep-reach work.

Installation and basics
Puller work starts before force: soak the shaft joint with penetrating oil, seat the jaws or legs squarely, and confirm the centre screw bears on the shaft centre, not on a thread or a seal. Advance the screw slowly, checking jaw seating after each turn, and stop if anything cocks sideways — a skewed pull cracks pulleys and throws jaws. For pressed-on pulleys with no jaw edge, do not improvise with a jaw puller; use the dedicated puller for that pulley or pay a shop with a press.

Safety essentials
- Wear eye protection — a slipped jaw throws metal.
- Never hammer a pulley off a shaft.
- Never stand in line with a puller under load.
- Seat jaws squarely before applying any force.
- Stop if the pull cocks sideways; reset, do not force it.
- Keep hands clear of the jaw and screw path under tension.

Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Jaws slip off | No clean edge or uneven seating | Reseat squarely or use a dedicated puller |
| Pulley will not move | Corrosion or press fit too tight | Soak with penetrating oil, then re-pull slowly |
| Pull cocks sideways | Uneven jaw seating | Release, reseat, advance evenly |
| Screw binds | Shaft centre missed or threads dry | Re-centre the screw and lubricate the thread |
| Pulley cracks | Excess force or skewed pull | Stop; replace the pulley and reassess the tool |
| No grip at all | Flush pressed-on pulley | Use a dedicated no-slip puller or a shop press |
Who should NOT buy these
Owners of pressed-on pulleys with no edge should not buy a jaw puller — it has nothing to grip.
Owners of small accessory pulleys should not buy a 10-ton push-puller — it is clumsy at that scale.
Anyone tempted to hammer should not buy any puller as a hammer substitute — buy patience and penetrating oil instead.
Owners beyond a tool’s spread should not buy it hoping it stretches — spread limits are real.

FAQ
What is the difference between an upper and a lower pulley?
Upper pulleys are usually accessory pulleys — alternator, power steering, water pump — on smaller shafts. Lower pulleys are usually crank pulleys, larger and often harmonic balancers, pressed onto the crankshaft. The puller must match the pulley’s size, grip and shaft, so position alone never decides the tool.
Do I need a special puller for a power-steering pulley?
Yes, usually. Pressed-on power-steering pulleys have no back edge for a jaw puller and no tapped holes for a bar puller, so they need a dedicated no-slip puller. A jaw puller on such a pulley slips, and forcing it damages the pulley and the pump shaft.
What do spread and reach mean?
Spread is how wide the puller opens around the part; reach is how deep it goes to grip it. Both must exceed your pulley’s dimensions. Several makers leave one or both unpublished, so verify against the maker catalogue before ordering.
Can I hammer a pulley off?
No. Hammering cracks pulleys, damages shafts and bearings, and throws metal. A puller applies controlled, centred force; a hammer applies shock in the wrong direction. If a pulley will not move under a puller, soak it, re-seat the tool, or take it to a shop with a press.
Why does my puller keep slipping?
Usually uneven jaw seating or no clean edge to grip. Release the load, reseat every jaw squarely, confirm the centre screw bears on the shaft centre, and advance slowly. A skewed start is the commonest cause of slips and cracked pulleys alike.
Is a ratcheting puller worth it for home use?
For solo home work, yes. Indexing legs stay in position while jaws are connected one at a time, which is the difference between a controlled pull and a juggling act. In a shop with a second pair of hands, a simple jaw puller does the same job.
What capacity puller do I need?
Match capacity to stubbornness: small accessory pulleys suit 2 to 5 tons, while crank pulleys and large gears often need more. A 10-ton push-puller is the answer for parts that defeated lighter tools, not the starting tool for small jobs.
Can a puller damage a harmonic balancer?
Yes, if misused. Harmonic balancers are bonded assemblies; a skewed pull or hammering can separate or crack them. Use the correct puller for the balancer, keep the pull straight, and stop if anything cocks sideways.
Which pick suits a first-time pulley job?
For a first job, the OTC 927 10-Ton Push-Puller is the friendliest start: its indexing legs suit solo work and its two yokes cover small and larger pulleys. Check spread against your pulley first, and keep the heavier push-puller in mind for stubborn crank pulleys.
