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.
