SHIFTING LINKAGE
Before assuming that internal transmission problems exist, check all external linkage. Inspect the shifting
linkage beginning with the control lever and work towards the transmission. Check for binding. Look for
broken or missing cotter pins and sheared keys.
CLUTCH ADJUSTMENT
Clutch adjustment is necessary anytime clutch slippage occurs.
Clutch rods when engaged should just completely compress the springs on the clutch actuating lever when
fully engaged.
To adjust, tighten the jam nuts until proper adjustment is obtained.
If external adjustments do not correct problems, internal examination may be necessary.
