Who Buys Pullers?
Who doesn’t???Gears, sprockets, pulleys, bearings, bushings, sleeves, etcMaintenance of all kindsField service, OEM, Fleets, HVAC, etcMost machinery, vehicles, and engines are made more
precisely than in the past with tighter tolerances today
»This is further reason to use the appropriate puller to remove/install
these components to minimize damage
»Additionally, these items increasingly use more highly engineered
materials than in the past…often are more expensive as well…so
minimizing damage to increase potential reuse saves money

Competition…does not promote pullers
5Snap-on Industrial Training – CG Gear Pullers© Snap-on Incorporated, 2014
Competition
SPX/OTC: Large competitor for two jaw and three jaw pullers. Primarily offshore origin product. Combination of cast and forged jaws dependent on product. Fairly basic designs with bolt/jaw attachments. Low cost supplier.
Posi Lock: Specialty US manufacturer using a patented “cage” retention design. Produces a wide array of manual pullers1 to 40 ton and hydraulics up to 100 tons. Internet, MRO’s, WD’s
6Snap-on Industrial Training – CG Gear Pullers© Snap-on Incorporated, 2014
Competition
Enerpac: Large manufacturer of pullers…primarily hydraulic cylinder based. Snap-on Industrial partner.
KD: Typically smaller tonnage manual pullers. Feaure a “ratcheting” jaw and tang mechanism to allow the user to easily set the jaws in place.
Proto: Line is similar to SPX/OTC with a number of sourced manual pullers. Pullers use a “swing arm” configuration. Typically lower cost & not easy to adjust/set.
Kukko: Large puller manufacturer in Germany…limited distribution in US (MSC). Premium product, innovation such as stackable jaws “Armlock”, easy adjustment ledger yoke, interchangeable jaw configurations.

The ABC’s Of Selecting The Right Puller
A. What type of puller do I want to use?
B. Determine the “reach” and “spread” needed
C. Estimate the puller tonnage
9Snap-on Industrial Training – CG Gear Pullers© Snap-on Incorporated, 2014
A. What Type Of Puller Do I Want To Use?
10Snap-on Industrial Training – CG Gear Pullers© Snap-on Incorporated, 2014
The pullers reach must be equal to or
exceed the same distance on the part
B. Determine The “Reach” And “Spread” Needed
The puller’s spread is the width of the part
Place the puller jaws as close to the center
shaft as possible
11Snap-on Industrial Training – CG Gear Pullers© Snap-on Incorporated, 2014
Generally, if you already have the correct “reach &
spread”, you will usually have the proper tonnage. If in
doubt, use the next larger size
C. Estimate The Puller Tonnage
12Snap-on Industrial Training – CG Gear Pullers© Snap-on Incorporated, 2014
Selecting the Right Puller
Always use a three jaw, when possible» Stable, safer, more metal to metal contact

Hydraulics
Pumps
»Auto cutoff
»Pressure gauge
»Quick coupler/ check valve
»Quality hose with spring guards
Single Stage & Two Stage
»A two stage pump (such as CG420-2S) operates more quickly
than a single stage pump (exp., CG420-2A)
»Generally, a two stage pump requires 1/3 the number of
strokes as a single stage pump
