Care must be taken to avoid damage to cover when removing bear-
ing. Use sharp fast hammer blows. Keep bearing filled with
petrolatum. Increase strength of hammer blows until bearing starts to
lift from cover. Hydraulic action from grease forced under bearing
will force bearing from cover.
Place 5/16 inch (7 mm) diameter pin punch (9) in bearing bore. Using 12 ounce or heavier hammer make a
sharp fast blow to drive punch into the bearing bore. Some petrolatum will escape from fluid ports, but
most will fill cavity below the bearing.
Refill bearing bore with grease and drive grease into bearing bore. Continue to add grease as needed, and
don’t give up on this removal procedure. Hydraulic pressure buildup in bottom of cover will force bearing
up. Repeat until bearing is out.
Wipe excess grease from bearing cover and wash with solvent.
