2-PLATE SLIP CLUTCH ADJUSTMENT (FIGURE 9)
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected if the cutter strikes an obstruction.
A new slip clutch or one that has been in storage over the winter may seize.
Before operating the cutter, make sure it will slip by performing the following
operation:
1.
Turn off tractor engine and remove key.
2.
Remove driveline from tractor PTO.
3.
Loosen six 10 mm cap screws (6) to remove all tension from Belleville
spring plate (5).
4.
Hold clutch hub (3) solid and turn shaft to make sure clutch slips.
5.
If clutch does not slip freely, disassemble and clean the thrust plate faces
(4), flange yoke (1), and clutch hub (3).
6.
Reassemble clutch.
7.
Tighten Belleville spring plate (5) until it is against the thrust plate (4) of
the clutch, and then back off each of the six nuts by 2 full revolutions. The
gap between Belleville spring plate and thrust plate should be 3.18 mm
(1/8 in) as shown in Figure 9.
8.
If a clutch continues to slip when the spring is compressed to 3.18 mm
(1/8 in) gap, check friction discs (2) for excessive wear. Discs are 3.18
mm (1/8 in) when new. Replace discs after 1.16 mm (1/16 in) wear.
Minimum disc thickness is 1/16".
