CLUTCH MAINTENANCE SECTION (CONTINUED)
C. REMOVAL OF CLUTCH/PUMP ASSEMBLY (CLUMP) FROM ENGINE
1. Remove clamps and piping from the suction and discharge side of pump.
2. Place a jack under bell housing of engine to support the rear of the engine after clump has
been removed.
3. Place clutch control in the ENGAGE position to hold clutch facings in place when removing
clutch from engine. Unbolt the rod which connects the clutch operating lever to operator’s
platform clutch handle
4. Attach a suitable lifting device to clutch/pump drive housing (33). Remove bolts that secure
the drive housing to the engine flywheel housing and the two bolts that hold the drive housing
to the HydroSeeder
®
frame.
Caution should be exercised when removing clutch/pump housing
from the engine so that the facings and pilot bearing are not damaged.
5. Support the housing assembly on blocks with the output end of the shaft down.
6. Remove the clump nameplate (16) from the housing for improved access to internal parts.
D. CLUTCH FACING PLATES 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.
2. Insert the new facing plates (three segments) in between clutch body (25) and pressure
plate (28), and center the facings as close as possible.
3. Lock clutch facings between pressure plates as follows:
A. Remove drive ring (27) 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 (28) almost contacts clutch facing (26).
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 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
counter-clockwise 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.
