TORQUE LIMITER
Avoid overheating of the Torque Limiter by too long or too frequent slipping since this can damage the
friction plates and limiter parts. When checking the Torque Limiter for overheating, DO NOT touch with
hand. It could be extremely hot and cause severe burn.
If an adjustment is required, this may be done in the field by following the procedure outlined below.
Following these instructions will give maximum rated torque and long life. See FIGURE 13.
(a) With the three Capscrews (#8) backed out until the points are below the surface of the
circular Adjusting Nut (#7), run Adjusting Nut up finger-tight, or slightly less than finger-tight.
(b) Alternately tighten the hardened, cup point Capscrews (#8) no more than one-half turn at a
time until the Capscrew heads "Bottom Out". Do not over tighten the Capscrews nor completely
flatten the Spring Washers (#5).
If the Hub is removed from the Shaft for any reason, the Shaft and Hub should be coated with a heavy
grease before reassembly to prevent Hub from freezing to Shaft.
SEASONAL TORQUE LIMITER MAINTENANCE
It is important that the Torque Limiter slips when an obstacle or load heavier than the setting is encoun-
tered. Before using the Torque Limiter each season, use the following procedure to make sure it will slip
and give the overload protection required.
1. Loosen Bolts (1) until gap between adjusting nut (2) and guide ring is approximately 1/16".
2. Attach machine to tractor, set engine at approximately half throttle and quickly engage PTO. This
procedure will break clutch facings loose and allow the proper torque to be maintained.
3. Return the bolts to their original position as described in (b) above.
NOTE: If machine sits outside longer than 30 days and is exposed to rain and humid air, the Torque
Limiter should be removed from machine and stored in a dry area. Torque Limiter facings will soak up
moisture and cause the metal plates to rust badly. When this occurs, the break-away torque increases
greatly and damage to gearbox, driveline, or tractor PTO can occur.
SLIP CLUTCH REPAIR PROCEDURE
1. Remove two bolts from top cover plate which holds shield bracket to gear box.
2. Remove locknuts #11 from bolts #12.
3. Remove cotter pin #13, castle nut #14, and washer #15. NOTE: It may be necessary to rotate yoke to
remove cotter pin. Remove driveline yoke from shaft.
4. Loosen three bolts #8 until large nut #7 maybe removed from hub #1.
5. Remove all parts from hub #1.
6. Clean or sand outer plates #2 and center plate #4 to remove rust or burned lining material from plates.
7. Reassemble clutch as shown in figure 11 replacing parts as necessary.
