Removing and Replacing Ball Bearings

Should it become necessary to replace bearings, the bearing bore and
cavity should be thoroughly cleaned and repacked with
approximately 1/2 teaspoonful of recommended grease (Chevron SRI
#2 or equivalent).

Bearings should be removed with bearing pullers using a center insert
in the end of the shaft to protect the shaft center. If a puller is not
available, use a fiber hammer and transmit blows through a hard wood
block.

To re-install ball bearings, either in a press or on the bench, pressure
should be applied to the inner race by using a square faced sleeve or
piece of pipe that will fit over the shaft, to avoid damaging the
bearing. If a press is not available and a hammer is used, the blows
should be transmitted against the sleeve by a block of wood or fiber.

Reassembly

Follow reverse procedure as outlined for Disassembly. Having
marked the brackets in the original position, replace as marked.
