OPERATION FOR DRUM AND ROTOR REMOVAL
Figure 2
1. Refer to the vehicle service manual for instructions
on using an appropriate lifting device to hoist the
vehicle off the ground. Lift the vehicle just far enough
to remove the wheel and tire.
2. After removing the wheel, completely thread two lug
nuts back onto two opposing wheel studs. Back off
the lug nuts three or four turns to allow the drum to
be pulled away from, but not fall off, the wheel hub.
See Figure 1.
3. Set the Drum/Rotor Puller Arms an equal distance
apart from the center on each side of the brake drum
or rotor.
4.
Grease the two washers and short hex nut.
On
the inside of the T-Bar, slide on the two washers then
thread the short hex nut up the drive bolt.
See Figure 1.
5. With the forcing screw at the center of the wheel hub and aligning the male notch in the drive bolt with the
female notch in the axle, position the puller jaws in the groove between the brake drum and the backing plate, or
securely on the back side of the rotor for disc brakes. Adjust the jaws on the crossbar as needed to fit. Lightly
secure the Set Knobs so that the arms do not move unintentionally during use.
6. Verify the jaws have good contact with the drum or rotor, and hand-tighten the forcing screw to the wheel hub/axle.
7. For stubborn applications or where the pulling jaws do not engage your drum or rotor securely enough, you may
use your own ratchet strap to provide extra clamping. Position your strap around the arms on the outer edge
near or just before the retaining lip of the arms. Tighten the ratchet strap securely. See Figure 2.
8. Using a 1.25" or 32mm wrench, retain and brace the short hex nut to prevent its movement. With a 1.25"
socket,
impact the drive bolt. With the short hex nut retained, this should push the drive bolt against the hub/axle and
pull the arms and drum or rotor.
9. Remove your strap (if used) and the puller from
the brake drum/rotor. Remove the lug nuts and remove the brake
drum/rotor.

For extra bracing when pulling, the Drum/Rotor
Puller Arms are designed with a lip to work with and
retain your own ratchet strap. Use when necessary.
