CLUTCH MAINTENANCE SECTION (CONTINUED)
D. CLUTCH FACING PLATES (ITEM 30) REPLACEMENT
A common indication that the facing's friction surface is worn out is that the adjusting ring cannot
be turned any tighter. To replace the facing plates, remove the clutch/pump from the engine as
described above and proceed as follows:
1. Disengage (turn off) clutch operating lever, and remove the old facing plates (30).
2. Insert the new facing plates (three segments) in between clutch body (34) and pressure
plate (29), and center facings as close as possible.
3. Lock clutch facings between pressure plates as follows:
A. Remove drive ring (31) from engine flywheel so that it can be used to center the
facings.
B. With clutch assembly resting on a workbench, turn clutch adjusting ring
counterclockwise until pressure plate (29) almost contacts clutch facing (30).
C. Place clutch driving ring over clutch facings with teeth in driving ring in mesh with
teeth of clutch facings, and locate driving ring centrally relative to the pressure
plate and clutch body.
If driving ring is not properly located relative to the pressure plate and
clutch body, the clutch cannot be assembled to the fl ywheel, as the
teeth of clutch facings will not enter the teeth of driving ring, even though the clutch drive
shaft enters the pilot bearing.
D. Engage (turn on) clutch by applying pressure on top of release sleeve and collar
assembly (20), and lock clutch facings between pressure plate and clutch body. If
clutch facings are still free to move, disengage (turn off) clutch, and turn adjusting
ring counterclockwise just enough to lock the clutch facings in place when clutch is
engaged (turned on).
Engage clutch (turn on) until the clutch assembly is attached to the
engine.
4. Remove clutch driving ring (31) from clutch facings and attach it to the flywheel with the
specified bolts and lock washers.
5. Before reinstalling clutch onto engine, lubricate release sleeve (21) through the grease
fitting mounted on its side.
6. To reinstall the clutch/pump assembly onto the engine, reverse the procedure outlined
under REMOVAL OF CLUTCH / PUMP ASSEMBLY (CLUMP) FROM ENGINE SECTION.
7. When clutch / pump are reinstalled, check handle, engage pressure, and adjust if
necessary.
