Inspection and Repair

1. Make the necessary repair or parts replacement if

wear, damage or any other abnormal conditions are
found during inspection.

2. Wash all parts thoroughly in clean solvent. Be sure all

old lubricant, metallic particles, dirt, or foreign
material are removed from the surfaces of every part.
Apply compressed air to each oil feed port and
channel in each case half to remove any obstructions
or cleaning solvent residue.

Bearings

1. Inspect the condition of all bearings. Wash bearings

thoroughly in a cleaning solvent. Apply compressed
air to the bearings.

NOTE: Do not allow the bearings to spin. Turn them
slowly by hand. Spinning bearings may damage the
rollers.

2. Lubricate the bearings with a light oil and check them

for roughness by slowly turning the race by hand.

Ball Bearing Play

1. Use a dial indicator to measure the ball bearing play.

2. If the measured value exceeds the specified limit, the

ball bearing must be replaced.

Limit : 0.2 mm (0.008 in)
