Secondary Clutch Service - Toro Workman GTX Service Manual

Secondary Clutch Service

1. Use secondary clutch press tool (see Special Tools
in this chapter) to compress the compression spring
enough to allow removal of the retaining ring (item 7)
that secures internal clutch components.
2. Remove retaining ring.
3. Carefully, release clutch press tool to allow the spring
to extend fully.
4. Remove outer spring retainer, spring and inner
spring retainer from clutch.
5. Make note of the "X" mark cast into the stationary
sheave and moveable sheave before removing the
moveable sheave. These marks must be aligned during
assembly for proper clutch operation.
6. Separate the clutch sheaves. Locate and retrieve
thrust washer.
7. Clean and inspect secondary clutch components:
A. Clean all dust and debris from clutch compo-
nents. If necessary, use contact or brake cleaner to
remove any oil or other lubricants from clutch com-
ponents.
B. Inspect the spring and replace if damaged or fa-
tigued.
C. Check the rollers in the stationary sheave for
binding or wear. If binding or uneven wear is found,
replace secondary clutch assembly.
D. Check the contact surface of the sheaves for
wear and/or fraying. If wear or damage is found, re-
place secondary clutch assembly.
IMPORTANT: For proper secondary clutch opera-
tion, DO NOT lubricate secondary clutch compo-
nents.
8. Assemble the secondary clutch in the reverse order
of disassembly. Make sure that the "X" mark cast into the
stationary and moveable sheaves are aligned. Also,
make sure that the retaining ring is fully seated in groove
after installation.
