OPERATION
5.2 INITIAL ADJUSTMENTS
5.2.2 TORQUE LIMITER (SLIP CLUTCH)
The CWS comes equipped with a torque limiter (slip clutch)
on the main drive of the CWS. The torque limiter is set in the
engaged position from the factory. Before use, the slip clutch
must be slipped and adjusted to ensure proper function.
ALLOWING THE TORQUE LIMITER TO SLIP
1. Loosen the center locknuts (Figure 51) on the torque
limiter so that the pressure is relieved from the pres-
sure plates.
2. With the combine engine at idle speed, engage the PTO
for 2-3 seconds to make the torque limiter slip.
Do not
allow the torque limiter to slip for more than 2-3
seconds at a time to prevent damage to the linings
.
3. If the torque limiter does not slip, repeat the procedure 2
or 3 times. If it still doesn’t slip, check that all the center
locknuts are loosened and not placing tension on the
pressure plates.
4. After the torque limiter has slipped, refer to the next
section for instructions on how to reset the torque limiter.
ADJUSTING THE TORQUE LIMITER
After the torque limiter has slipped, it must be adjusted to
the tension required to operate the header. The goal of this
procedure is to have the torque limiter slip momentarily upon
initial startup and then operate normally. The slip clutch
must not slip at full RPM.
1. Slowly engage the PTO with the engine running at idle
speed.
2. If the torque limiter does not slip, shut off machine and
loosen the center locknuts in 1/4 turn increments until
it slips momentarily when the header is engaged. If the
torque limiter continues to slip after start-up, tighten
the center locknuts in 1/4 turn increments until it slips
momentarily when the header is engaged.
3. The torque limiter is ready for use.
At the end of the season, or before any long period of
non-use, loosen the center locknuts to relieve the pres-
sure on the linings.

5.2.1 MANIFOLD ADJUSTMENT
1. Adjust your header and pickup reel per the manufac-
turer’s recommendations.
2. Position air manifold to maintain clearance between air
tubes and reel bats/tines.
3. Adjust the air tube position to point at the back of the
sickle bar. This adjustment refers to the longer air tubes
on Crary Wind Systems.
4. Loosen tilt actuator clamp and adjust so the actua-
tor is in middle of stroke (approx. 2” of actuator shaft
exposed) with tube nozzles pointed at the back of the
sickle bar. Retighten clamp.
5. Make sure air tubes do not hit ground when reel is at
its lowest operating position. Adjust as required.
Place all controls in neutral or off , stop combine engine,
set parking brake, remove ignition key, wait for all mov-
ing parts to stop, then properly block machine before
servicing, adjusting, repairing, or unplugging.
WARNING
To prevent burn-up of slip disks the torque limiter (slip
clutch) must be adjusted prior to use.
