4. Place the puller over the component to be pulled. (See Figure 3.) When only the inner
bearing race is remaining on the shaft, clean the shaft first with emery cloth and then attach
the jaws in the ball groove.
If the jaws appear to be coming out of the ball groove, release hydraulic pressure and re-
tighten the T-Handle by hand. This may be necessary when the puller is new to get the jaws
to properly seat in the cage.
5. Turn the T-handle clockwise to tighten the jaws firmly onto the component.
6. Make sure that the puller is square with the component to be pulled. Advance the plunger
until the ram point contacts the shaft to ensure correct alignment. (If necessary, refer to the
pump’s instruction sheet.) The center of the ram point should be aligned with the center of
the shaft. Continue to advance the plunger slowly to pull the component off of the shaft. Do
not re-tighten the T-handle during the pulling operation. Never exceed the maximum torque
rating of the pullers.
Maintenance
Always clean the puller after use and store in a clean, dry place.
100-Ton Hydraulic Puller
WARNING
Do stand on, under, or near puller while in use. Keep hands, feet and clothing
away from moving parts.
WARNING
When transporting puller, always place the puller in its lowest position and
remove ram extenders.
1. Make sure that all items being pulled are supported by a means other than the puller. Do not
use the puller for lifting or supporting objects.
2. Align the puller to the shaft to ensure a straight pull. (The puller’s lift cart can raise the
puller up to 5 feet. For distances beyond 5 feet, the puller can be removed from the cart. See
Removing Puller from Lift Cart.)
To raise the puller, place the cylinder control valve in the “Hoist Oil Supply” position, open
the puller hoist vertical control valve, and raise the puller by placing the remote jog switch
in the “On” position.
When puller has reached the desired height, release the remote jog switch and close the
vertical control valve.
To lower the puller, place the cylinder control valve in the “Hoist Lower” position, turn the
hoist vertical control valve counterclockwise, and close the hoist vertical control valve after
the puller has reached its desired height.
Note
The restrictor valve, located at the top of the hoist cylinder, is used to control the rate of
puller descent. This valve should be set at the desired rate and locked in place using the nut
on the valve shaft. (An appropriate starting point is one full turn from the closed position
This restrictor valve is only a one-way restrictor valve; it does not affect the rate at which
the puller is raised.)
