CAMSHAFT GEARS AND AUTOMATIC DECOMPRESSOR
Check the gear teeth for wear and damage.
Inspect the automatic decompressor for damage and ensure it is in
working order.
If any defects are found, replace the camshafts and the timing chain
as a set.
Do not attempt to disassemble the gears and the automatic
decompressor unit. They are unserviceable.
TIMING CHAIN TENSION ADJUSTER
The timing chain tension adjusters are maintained at the proper ten-
sion automatically. Release ratchet A and move push rod B into
position to see if it slides freely. If the push rod is difficult to move, or
if the ratchet mechanism is faulty, replace the timing chain tension
adjuster assembly with a new one.
