WHAT CAUSES CLUTCH PACKS TO BURN UP?

There are various reasons why an industrial transmission's clutches burn up. We have attempted to list the most common.


1. LACK OF LUBRICATION.
Look for a kink in a line, a collapsed filter, or low fluid level.

2. INCHING (OR CLUTCH CUT-OFF) IMPROPERLY ADJUSTED.
The creeper pedal applies the clutches. This causes the unit to creep forward (or backward). If the pedal does not return to the proper point, the clutches will remain on, creating heat and friction.

3. STEEL SEPARATOR PLATES THAT SHOW HOT SPOTS.
This may be caused by warpage or distortion, incorrect loading of curved discs or pistons, the wrong thickness of plates, or incorrect pack clearance.

4. INCORRECT ASSEMBLY OF CLUTCH PACK.
remanufacture with new clutch plates and seal rings.

5. FLUID THAT HAS BROKEN DOWN OR IS CONTAMINATED.
The contaminants may be imbedded in the clutch plates or may have constricted oil passages.

6. SHIFTING CREATES HEAT.
If the clutch packs are applied during an open throttle shift, the heat is even greater. So heat distress can occur if the operator must shift frequently, or fails to stop between directional changes.

7. IF THE ENGINE IS MORE POWERFUL THAN THE DESIGN OF THE CONVERTER AND THE TRANSMISSION.
The clutch packs will suffer from the over-torquing of the power train.
