CLUTCH/PUMP COMBINATION (CLUMP) MAINTENANCE (CONTINUED)
D. INSTALLING NEW SEAL ASSEMBLY (CONTINUED)
3. Install the seal spring on the hub of pump impeller. After coating the threads on pump
shaft with an anti-seize compound, install pump impeller and seat it securely.
4. Utilizing O-ring (2), reinstall suction cover using eight bolts (5B). At this time, check to
see that pump runs freely. If pump impeller rubs suction cover, you do not have pump
impeller tight on pump shaft or the suction cover needs to be readjusted. See IMPELLER
CLEARANCE SECTION. Tighten bolts uniformly using 15 lb-ft. (20 N•m) on the torque
wrench.
5. After reinstalling suction pipe assembly, lubricate, and tighten victaulic clamps. Service the
automatic pressure lubricator. See EQUIPMENT CHECK SECTION.
CLUTCH MAINTENANCE SECTION
This is an outline of the clutch adjustment and lubrication procedure. When you perform
maintenance beyond this outline, refer to the power take-off clutch manufacturer's service
manual. In order to properly identify parts when ordering replacement parts, always refer to the
unit and specification number stamped on the nameplate located on the top center of the clump
housing.
Clutch maintenance should be done only while engine is not running
and battery cables are disconnected. Failure to comply could result in
minor or moderate personal injury. Failure to comply could also result in product or property
damage.
A. ADJUSTMENT
The clutch described in this manual does not automatically adjust to compensate for wear of the
clutch facing(s), and must be manually adjusted. Maintaining the correct engagement pressure is
the responsibility of the owner / operator. The owner / operator must periodically adjust the clutch to
ensure correct clutch operation.
The clutch should be adjusted if the force to engage the clutch drops by 10 - 15% of the specified
engagement force. Destructive damage may have already occurred if engagement force is
allowed to diminish to the point where the clutch fails to carry the load (slippage), or if facing(s)
has (have) overheated.
Do not adjust clutch too tightly. Overtightening can cause
component failure.
If the clutch does not pull, overheats, or the clutch operating lever pops out, the clutch must be
adjusted. Proceed as follows:
1. Remove clump nameplate (10A) in the drive housing (10), and rotate clutch until adjusting
lock collar and lock screw (28) can be reached. To avoid dropping the adjusting lock (28)
into the housing, use caution when removing or disengaging.
2. With a flat blade screwdriver or 7/16 inch wrench, loosen the adjustment lock bolt and
loosen or remove the adjustment lock.
3. Turn adjusting ring (27) counterclockwise to obtain recommended operating lever
pressure. Rotating the adjustment ring clockwise will loosen the clutch. Adjust to obtain
the proper handle engagement force. Lever engagement force should be measured with a
spring scale at the end of the lever and pulling perpendicular to the lever.
4. When clutch is properly adjusted, reposition the adjustment lock (28) in the notches.
Install and tighten the adjustment lock bolt. Rotate clutch and re-engage. Reinstall the
nameplate (10A).
