401RW017

Play in universal joint.
Limit: Less than 0.15 mm(0.006 in)

Spider pin should be smooth and free from fretting or
galling.
Visible signs of needle presence is normal, but wear
should not be felt.
401RW028

Preload of the universal joint.
Preload should be 0 to 49 N (0 to 11.0 lb).
Joints should rotate smoothly and freely and should
exhibit no rough or ratchety movement.
401RW019

Inspect splines of slip joint for wear.
The nylon-coated spline should be free from nicks
and dings and the underlying steel spline should not
be visible.
After cleaning the nylon coating spline, the coating
should exhibit only slight indication of wear.
Grease volume is approximately 10 grams of grease
in total. Grease should be evenly applied to both the
female and the male slip splines using a small brush.
After assembly of the slip joint, the sliding joint should
be fully worked from the full collapsed to the full
extended position.

1. Apply grease evenly to both the female and male
splines.
2. Apply a small amount of grease by finger to the outer
lips of the boot.
3. Slide the boot (smaller diameter side) onto the spline
yoke shaft being careful not to damage the spline
coating or boot.
4. Insert the spline yoke shaft spline into the tube
assembly being careful to maintain proper phasing.
The spider holes should be in line as originally marked
prior to disassembly.
5. Position boot onto tube and yoke shaft in its
assembled position.
6. Attach boot clamps and secure using pliers.7. Be sure clamp is properly seated and secure.
CAUTION: Only use a similar type or same as the
original type clamp. Using any other clamp may
create an imbalanced shaft or lead to grease leakage.

Inspection and Repair
Make necessary parts replacement, if wear, damage,
corrosion or any other abnormal conditions are found
through inspection.
Check the following parts:

Rotor

Cylinder body

Cylinder bore

Piston

Guide bolt, lock bolt

Support bracket
NOTE: The piston seal, boot ring and dust boot are to be
replaced each time the caliper is overhauled. Discard
these used rubber parts and replace them with new ones.
