Type B Clutches

Clutch Run-In

Refer to Figure 5-8:

1. Using a pencil or other marker, scribe a line across the

exposed edges of the clutch plates and friction disks.

2. Carefully loosen each of the 6 nuts by exactly 1

revolution. It will be necessary to hold hex end of

retainer bolt in order to count the exact number of

revolutions.

3. Make sure the area is clear of all bystanders and

machine is safe to operate.

4. Start tractor and engage PTO drive at idle for 2-3

seconds to permit slippage of friction plates.

Disengage PTO, shut off tractor, and remove key.

Wait for all components to come to a complete stop

before dismounting from tractor.

5. Inspect clutch to ensure that the scribed markings

made on the clutch plates and friction disc have

changed positions. If any two marks are still aligned,

then the clutch did not slip as it should. Skip to

step 8 if all clutch plates slipped.

6. If the friction clutch did not slip, loosen the nuts one

more revolution. Make sure the nuts have full thread

engagement on the bolt and then repeat steps 4 - 5.

7. A clutch that does not slip must be disassembled to

separate the friction disk plates. See “Clutch

Disassembly, Inspection & Assembly” below.

8. Tighten each of the nuts on the clutch back to their

original location to restore clutch pressure.

9. Allow clutch to cool to ambient temperature before

operating again. Clutch is now ready for use.

10. The clutch should be checked during the first hour of

cutting and periodically each week. An additional set

of scribe marks can be added to check for slippage.

Clutch Disassembly, Inspection & Assembly

The clutch must be disassembled into its separate friction

disks if clutch run-in procedure above indicated that one or

more friction disks did not slip. See disassembly

instructions.

Disassembly

Refer to Figure 5-9:

1. Determine if you have a 2-plate clutch or 4-plate

clutch. Use matching illustration in Figure 5-9 below.

2. Measure from outside of belleville spring (#6) to

outside of plate (#4) on center line of all 6 bolts (#6).

Record these distances for reassembly.

3. Remove bolts (#7) evenly & belleville spring (#6).

4. Separate all friction disks (#2) from plates (#4 & #5),

hub (#3), and yoke flange (#1).

Inspection

Inspect all parts for excessive wear and condition. Clean

all parts that do not require replacement.The original

friction disk thickness is 1/8" (3.2mm) and should be

replaced if thickness falls below 3/64" (1.1mm). If

clutches have been slipped to the point of “smoking”, the

friction disks may be damaged and should be replaced.

Heat build-up may also affect the yoke joints.

Assembly

Reassemble each friction disk (#2) next to the metal

plate it was separated from. Install bolts (#7) through the

end plates and intermediate plates as shown and secure

with nuts (#8). Tighten each nut to the measured

distance (A) recorded in step 2 during disassembly.

IMPORTANT: If you have already loosened each

nut (#8) by 1 or 2 revolutions, retighten nuts before

measuring distance (A). Measure distance (A)

within (+/-.015") from outside of belleville spring (#6)

to outside of backing plate (#4) on center line of all

6 bolts (#7) and record before disassembling the

clutch. These six measurements must be kept and

reused when reassembling the clutch to restore the

belleville spring to its original pressure setting.
