Puller
A threaded hand
puller is a tool that usually consists of 2 to 3 jaws that
can hold onto an object (typically a gear or bearing) while
a threaded shaft exerts force on a shaft or opposing object
to aid in removing the object. Pullers come in a
variety of forms and can be specially built for a specific
purpose or generalized for use in different situations.
Pullers with locking jaws are usually easier to use not to
mention considerably safer.
A good puller
will avoid damage to an object by avoiding the need to use
blunt force, you know, a hammer. The puller is capable
of applying great amounts of force to an object with minimal
effort by the user.
Typical
threaded puller types
Internal puller
- These pullers have jaws that can grip an object from the
inside such as a bearing race allowing ease of removal.
External puller
- These pullers have jaws that can grab onto the outside of
an object such as a bearing cage allowing ease of removal.
Slide Hammer
Puller
Internal and
External Slide Hammer - Similar jaw design to the
internal and external pullers without the threaded shaft to
provide the opposing force. A weight on a shaft
provides the pulling force by the users hammering the weight
in an outward movement.

Basic
manual puller safety rules:
1. Always use puller with safety design to reduce
possible injury from puller jaws flying off or
snapping back.
2. Always select the proper gear puller for each
pulling job. Always use a gear puller equal to or
larger then required.
3. Before use, center bolt should be cleaned and
lubricated with high pressure grease or graphite
based lubricant.
4. Always wear safety goggles when using gear
pullers.
5. Always use hand tools on gear pullers. Avoid the
use of air powered tools.
6. Always make sure the gear puller is aligned with
the shaft, assuring a straight pull during
operation.
7. Never alter any part of a gear puller by cutting
or grinding. Never apply heat to any gear puller.
Applying heat could cause the puller to lose its
“strength.”
8. Should it become necessary to strike the puller
for removal of a stubborn gear or bearing, care
should be taken to strike the head of the center
bolt squarely. If after one or two sharp blows, the
gear or bearing remains stuck, select a larger
puller and proceed to remove the gear or bearing.
9. Always clean the gear puller after use and store
in a dry place.
