PULLERS What type of puller do I want to use? What combination will work best?
TOOLS Removing a Gear, Bearing, Pulley, Tools to Use

or Other Component from a Shaft
Jaw-Type Puller: Two- or three-jaw style, with three jaw being the best choice.
Manual or hydraulic with outside jaw positions.
Push-Pull Puller: Use male or female adaptors to thread into tapped holes on
the components.
Slide Hammer Puller: Used on light-duty applications. For use with attachments.
Bar-Type Puller with Bearing Separator: Bar type with side rods threaded into
the bearing separator provides a “knife edge” to get behind the component or when
there is not a good gripping edge.
HAND or Bore Push-Pull Puller: Use male or female adaptors.
Tools to Use
Pulling a Shaft Out of a Housing
Bar-Type Puller with Bearing Separator: Used when the housing lacks sufficient
surface for puller side rods to bear against.
Slide Hammer Puller: Used on light-duty applications. For use with attachments.
Slide Hammer Puller: Use with male or female adaptors. See this section for a full
listing of compatible adaptors.

Removing a Bearing or Bushing
Jaw-Type Puller: For inside jaw positions (inside pulls), a manual or hydraulic
from a Blind Hole Tools to Use
jaw-type puller can be used with pressure screw or slide hammer variations.
GENERAL
Expanded Collet Puller: The inside diameter should range between 1/4 and 7ʺ.
Pulling can be done with bridge, bar-type yokes or slide hammers.
Bearing Adaptors with Slide Hammer Puller: CJ127A, CJ128A and CJ137 bearing
adaptors with a CJ97-3A slide hammer should be used in this application.
Bar-Type Puller with Bearing Separator: Bar type with side rods threaded into the
bearing separator provides a “knife edge” to get behind the components or when
there is not a good gripping edge.
Determine the “Reach” and “Spread” Needed
The puller’s reach must equal or exceed the same distance on the part. The puller’s
spread is the width of the part.
Estimate the Puller Tonnage
Generally, if you already have the correct “reach” and “spread”, you will usually have
the proper tonnage. If in doubt, use the next larger size.

General Rules for Choosing Pullers
Manual Pullers: Pressure screw should be at least half the diameter of the shaft on
the pulling/pushing job.
Hydraulic Pullers: Maximum tonnage capacity (tons) should be 8 to 10 times the
diameter (in inches) of the shaft to be pulled or pushed.

Snap-on Puller Features
Anvil Head: Curved at the top and features a hex design. The curved head provides a
striking surface to handle those tough pulling jobs while the hex allows the pressure
screw to be easily turned with a standard hex wrench or a socket.
Spring-Loaded Locking Mechanism: Snap-on pullers feature a unique spring
®
tension locking mechanism that allows the puller jaws to easily lock onto the work
surface for both “outside” and “inside” pulling applications.
Two-Position Yoke: Allows jaws to be easily reversed to accommodate inside or
outside pulling situations. Interchangeable yokes accommodate two and three jaw
setups. Yokes are heat treated for additional strength and safety.
One-Piece Jaw Construction: Provides a stronger, safer jaw. Most competitive puller
jaws have holes drilled through them to allow for a bracket attachment. This hole
significantly weakens the competitor’s puller jaws.
Forged Jaws: Resist breakage, prolong tool life and provide additional strength.
Replaceable Points: Center pulling power to prevent cocking. Provide less friction
and minimum drag for easier turning of the pressure screw during the pulling process.
If damage occurs, simply replace the point and not the entire pressure screw.
Curved Jaws: Provide positive grip on the work surface.
