Type B Clutches

Clutch Run-In

Refer to Figure 5-6:

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.

Disassembly

Refer to Figure 5-7:

IMPORTANT: If you have already loosened each nut (#8) by 1 or 2 revolutions, retighten nuts before taking measurement (A). Measure distance (A) within (+/-.015") from outside of belleville spring (#6) to outside of 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.

1.Determine if you have a 2-plate clutch or 4-plate clutch. Use matching illustration in Figure 5-7 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).

Type B Clutch Assembly

Figure 5-7

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.

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.

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.
