Assemble the center bolt (2) into the forcing screw (1) of the tool, see Figure 5. Back the center bolt at least 25 mm (1 in) inside the forcing screw.
12.
Assemble the forcing screw (2) inside the puller legs (1), see Figure 6. Finger tighten the forcing screw to push the puller legs against the bearing.
13.
Using a 24 mm wrench to hold the forcing screw, use a 17 mm socket to tighten the center bolt until the bearing is removed from the gear housing,
see Figure 7. Do not reuse the bearing.
Important
Inspect the gear housing to ensure that no parts of the old bearing remain.
