INSPECTION AND REPAIR
Make the necessary adjustments, repairs, and part replacements if excessive wear or damage is discovered during
inspection.
Cylinder Body
1. Clean the cylinder body.
2. Check the fluid return port for restrictions and clean it if
necessary.
Cylinder Bore and piston Clearance
1. Clean the cylinder body and the piston.
2. Use an inside dial indicator to measure the cylinder bore.
3. Use a micrometer to measure the piston diameter.
4. Calculate the clearance between the cylinder bore and the
piston diameter.
If the clearance exceeds the limit, the entire slave cylinder
assembly must be replaced.
Cylinder Bore and Piston Clearance mm(in)
Standard Limit
0.07 (0.0028) 0.15 (0.006)
Piston and Piston Cup
Visually inspect the disassembled piston and piston cup for
excessive wear and damage.
Replace the inner parts with new parts (Repair kit A) shown in
the illustration.
