5. Remove oil tube by pulling out of the clutch shaft. Discard all seal rings. Remove snap ring from rear
clutch, lift cylinder assembly from shaft.
6. Remove the snap ring, hub, plates washer, and output gear. Remove and discard all seal rings.
7. Clean and inspect all bearings, bushings, shaft and other parts. Replace as required.
D. Clutch Shaft Assembly Hints
1. Handle all transmission parts with care. Nicks, scratches, or dents caused by careless handling of parts
can cause subsequent transmission failure.
2. Never dry bearings with compressed air. Do not spin bearings while they are not lubricated.
3. When assembling ball bearings, pressure should be applied to the member being assembled (inner ring on
shaft or outer ring on housing). Bearing must be started squarely on shaft or in housing and seated
squarely against shoulder. Check housing and shaft for nicks, scratches prior to bearing installation.
Always oil bearings and bushings during assembly as this will assure lubrication during the first few
moments of operation.
4. Parts incorporating bushings should be replaced if total radial clearance exceeds .0035.
Parts
incorporating roller bearings should be replaced if total radial clearance exceeds .0025.
5. Before installing oil seals, check shafts and bores for nicks and scratches. Make sure that the seals are
started squarely. Always press seals on the outside diameters, using a thick piece of shim stock around
the shaft to protect the sealing edge of the seal against possible damage when it is required to slide over
splines or keyways. Pre-lubricate oil seals and O-Rings immediately before installation.
6. Grease all seals, rings and center in grooves prior to installation. Be particularly careful against breakage
when installing seal rings.
7. Check all snap rings after installation, making sure that they are securely seated in their grooves.
8. Check all rotating parts for free motion.
