TWIN DISC “DRY” CLUTCH
A clutch that engages easily is out of adjustment. It will take most of your strength to lock the clutch in
place. Clutches are a high maintenance item and expensive to repair. New or rebuilt clutches require several
adjustments in the first few hours of operation. During this time the clutch plates are wearing in. Burned clutch
plates are never covered under warranty. Failure to properly adjust will cause the entire clutch to burn up.
To check clutch engagement, attach a torque wrench to the cast-in hex on the hand lever. Measure the
effort needed to force the clutch engaging linkage over center to lock up the clutch.
Engaging torque must be:
Between a minimum of 510 ft.-lbs. (691 Nm) and a maximum of 676 ft.-lbs. (917 Nm) for the Model SP318SBO
and, a minimum of 194 ft-lbs (263 Nm) and a maximum of 257 ft-lbs (348 Nm) for the Model 314SB1.
Frequently adjust and grease per the clutch manufactures manual.
ADJUSTING THE TWIN DISC CLUTCH
1. Shut down engine, disengage clutch and observe all safety procedures.
2. Open up the inspection plate on top of the clutch housing.
3. Turn the clutch so that the adjusting lock pin can be reached through the cover plate opening.
4. Press the adjusting lock pin and turn the adjusting ring clockwise one or two notches to tighten.
5. Release the lock pin and continue turning clockwise to the nearest notch.
6. Make sure the lock pin snaps out in the notch.
7. Reinstall the clutch plate and recheck engagement torque.
8. If engagement torque is not within the limits, re-adjust starting at step one.
CLUTCH SECTION/APPEARANCE
PAINT AND APPEARANCE
To help keep up the appearance of your Smoracy Equipment and reduce the possibility of surface rust follow
these steps:
1) The machine should be washed on a regular basis with a non-abrasive mild detergent and then rinsed
thoroughly.
2) If stone chip, paint scratch or paint crack occurs - it should be repaired immediately. Simply sand the edges
of the damaged paint area, mask off the surrounding area and add a primer and paint to the dry clean warm
surface. This will help keep the damaged area from spreading or getting worse.
3) If you are unable to sand and mask the area, there are containers of primer and paint available. A small
brush can be used to touch up the area.
4) Also, primer and most colors of paint are available in aerosol spray cans to simply spray over the effected
area after it is cleaned, dry and warmed. This method is not as reliable as the #2 process.
It is also reported that some equipment owners polish their machines at least yearly, and keep good mud flaps on
their towing trucks.
