CLUTCH MAINTENANCE SECTION (CONTINUED)
A. ADJUSTMENT (CONTINUED)
HANDLE PRESSURE
Variation in handle length directly affects the required handle pressure needed for clutch
adjustment. See the table below to determine the correct handle pressure.
A new clutch generally requires several adjustments until the friction
surfaces are worn in. Do not let clutch slip, as this will glaze the friction
plates and may ruin them.
B. LUBRICATION
The operating shaft bearings should be lubricated every one (1) to three (3) months, depending
on usage. The clutch cross shaft should be lubricated weekly. The clutch release bearing,
accessible by removing the clutch nameplate, should be lubricated daily using a hand operated
grease gun only.
1. Lubricant – Use any high grade, lithium-based number 2, short-fiber grease having an
operating temperature of 200˚F (93˚C) that is recommended for roller bearings.
Do not mix sodium- or calcium-based grease with lithium-based
grease. Lubricate sparingly to avoid oil seepage onto clutch facings.
2. Anti-Friction Bearings – Shaft bearings should be lubricated after every 50 hours of
operation. Shaft bearings can be lubricated through the fittings (41) with a short-fiber,
high-grade, high-temperature, lithium-based number 2 lubricant that has an operating
temperature of 200˚F (93˚C).
On occasion, use the same lubricant to lubricate the two fittings at the cross-shaft (26).
3. Clutch Lever and Linkage – Clutch levers and linkage should be lubricated with engine oil
after every 500 hours of operation.
C. REMOVAL OF CLUTCH / PUMP ASSEMBLY (CLUMP) FROM ENGINE
1. Remove clamps and piping from the suction and discharge side of the slurry pump.
2. Place a jack under bell housing of engine to support the rear of the engine after clump
has been removed.
3. Place the slurry pump clutch control in the ENGAGE position to hold clutch facings in
place when removing clutch from engine. Unbolt the rod that connects the slurry pump
clutch operating lever to operator’s platform clutch handle
4. Attach a suitable lifting device to slurry pump clutch drive housing (10). Remove bolts
that secure the drive housing to the engine flywheel housing and the two bolts holding 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, making sure the output end of the shaft is facing
downward.
6. Remove the clump nameplate (10A) from the housing for improved access to internal
parts.
