Driveline Clutch

Cutter drive components are protected from shock loads by a slip-clutch. The clutch must be capable of slippage during operation to protect the gearbox, driveline and other drivetrain parts.

Prior to initial operation and after long periods of inactivity, the clutch should be “run-in” to remove any oxidation that may have accumulated on the friction surfaces.

!CAUTION!

Engage parking brake, disengage PTO, shut off tractor, and remove key before making any of the following adjustments.

Clutch Run-In

Refer to Figure 4-2:

1.Using a pencil or other marker, scribe a line across the exposed edges of the clutch plates and friction discs.

2.Carefully loosen each of the 8 spring retainer nuts on the clutch housing a total of EXACTLY 2 revolutions. It will be necessary to hold the hex end of the retainer bolt in order to count the exact number of revolutions.

3.Start the tractor and engage the PTO drive for 2-3 seconds to permit slippage of the clutch surfaces. Disengage the PTO, then re-engage a second time for 2-3 seconds. Disengage the PTO, shut off tractor and remove key. Wait for all components to stop before dismounting from tractor.

4.Inspect the clutch and ensure that the scribed markings made on the clutch plates have changed position. If any two marks on a friction disc and plate are still aligned, such indicates that slippage has not occurred and the clutch must be disassembled to separate the friction discs, see “Clutch Assembly and Disassembly” below.

5.Tighten each of the 8 spring retainer nuts on the clutch housing EXACTLY 2 revolutions to restore the original clutch setting pressure.

6.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. See “Clutch Assembly and Disassembly” below to adjust for proper spring length.

Clutch Assembly and Disassembly

Refer to Figure 4-3:

If the clutch run-in procedure, see “Clutch Run-In” above, indicated that one or more friction discs did not slip, the clutch must be disassembled to separate the friction discs.

Disassembly of the clutch is simply a matter of first removing the spring retainer nuts (#1), springs (#2) and bolts (#3) from the assembly. Each friction disc (#4) must then be separated from the metal surface adjacent to it. Inspect all parts for excessive wear and condition. Clean all parts that do not require replacement.

Clutch Disassembly

Figure 4-3

The original friction disc thickness is 1/8" (3.2mm) and should be replaced if the thickness falls below 3/64" (1.1mm). If the clutches have been slipped to the point of “smoking”, the friction discs may be damaged and should be replaced. Heat build-up may also affect the yoke joints.

Refer to Figure 4-4:

Install new friction discs if needed and reassemble all components in proper order. Progressively tighten each spring retainer bolt until the spring length is between 1.120 to 1.110 inches for 540 RPM and 1.020 to 1.010 inches for 1000 RPM.
