Slip Clutch Components
Figure 5-8
Inspect Friction Disc
Refer to Figure 5-8:
Do not touch the clutch while it is hot. Inspect friction
disc (#6) for wear and damage daily. Replace the disc
when they are worn down to nothing or damaged. Refer
to
Replace Friction Disc
Remove Driveline
1. Shut tractor down according to
2. Pull back on the driveline lock collar and pull driveline
yoke from the tractor’s power take-off shaft.
3. Collapse the driveline by pushing the tractor end of
the driveline toward the opposite end of the driveline.
4. Remove bolt(s) clamping the slip clutch to the
implement.
5. The drive shaft with clutch is heavy. Grasp clutch
firmly with both hands and slide the clutch off the
implement.
Disassemble Clutch
Refer to Figure 5-8:
1. Place the clutch and universal joint assembly on a
bench with the clutch end accessible.
2. Remove nuts (#1) and bolts (#10). These bolts and
nuts hold the clutch together.
3. Remove compression plate (#2), spacers (#3), disc
spring (#4), pressure plate (#5), friction disc (#6), hub
flange (#7), friction disc (#6), and spacer (#8).
4. Discard friction disc (#6).

Inspect Clutch
1. Inspect steel and iron parts for wear, warpage,
and/or cracking and replace if necessary.
2. Clean any rust or dust from plate surfaces with a wire
brush or steel wool.
Assemble Clutch
Refer to Figure 5-8:
1. Place spacer (#8) against yoke flange (#9).
2. Place one new friction disc (#6) against yoke
flange (#9) and hub flange (#7) against the friction
disc as shown.
3. Place the second new friction disc (#6) against hub
flange (#7) and the flat surface of pressure plate (#5)
against the disc.
4. Place the inside diameter of disc spring (#4) against
pressure plate (#5). Make sure the inside diameter of
the spring contacts the fins of the pressure plate and
the spring is centered on the pressure plate.
5. Insert bolts (#10) through yoke flange (#9) and
pressure plate (#5).
6. Assemble spacers (#3) on bolts (#10).
7.
Assemble compression plate (#2) on bolts (#10) and
install nuts (#1).
8. Tighten all nuts (#1) until spacers (#3) cannot be
rotated by hand, then back-off the nuts until the
spacers will rotate by hand.
Reattach Driveline to Implement
1. Attach clutch hub (#7) to the implement with the
existing bolts that were removed earlier. Make sure
the grooves on the input shaft align with the grooves
in the clutch.
2. Reinstall any shielding that was moved or removed.
3. The clutch must be run-in before it is used. Refer to
Clutch Adjustment
Refer to Figure 5-8:
The clutch will need adjusting from time to time due to
wear on the friction discs. Adjust the clutch by tightening
nuts (#1) until spacers (#3) cannot be rotated and then
back-off nuts until the spacers will rotate by hand.
Adjust clutch at the start of each season and whenever
the clutch begins to slip easily and/or often.
IMPORTANT:
IMPORTANT: Assemble small
diameter (I.D.) of spring (#4) against fins on pressure
plate (#5).
