DIAGNOSIS
Before attempting to repair the clutch, transmission or
related linkages for any reason other than an obvious failure,
the problem and probable cause should be identified. A large
percentage of clutch and manual transmission problems are
manifested by shifting difficulties such as high shift effort,
gear clash and grinding or transmission blockout. When any
of these problems occur, a careful analysis of these difficulties
should be accomplished and the following checks and
adjustments performed in the presented sequence before
removing the clutch or transmission for repairs.
CLUTCH ADJUSTMENT
A. Clutch Free Pedal Travel
I. The clutch free pedal travel adjustment should be
made as outlined in "Maintenance and Adjustments."
2. Check clutch linkage for lost motion caused by loose
or worn swivels, deflection of mounting brackets or damaged
cordon shaft.
1. Run the engine a normal idle with transmission in
neutral and clutch engaged.
2. Disengage the clutch, wait nine seconds and shift the
transmission to reverse. No grinding noise should be heard.
A grinding noise indicates incorrect clutch adjustment, lost
motion, clutch misalignment or internal problems such as
failed dampers, facings, cushion springs, diaphragm spring
fingers, pressure plate drive straps, etc.
