Camshaft Chain Tensioner
Camshaft Chain Tensioner Removal
CAUTION
This is a non-return type camshaft chain tensioner
[A]. The push rod does not return to its original po-
sition once it moves out to take up camshaft chain
slack. Observe all the rules listed below:
When removing the tensioner, do not take out the
mounting bolts only halfway. Retightening the
mounting bolts from this position could damage
the tensioner and the camshaft chain. Once the
bolts are loosened, the tensioner must be removed
and reset as described in "Camshaft Chain Ten-
sioner installation."
Do not turn over the crankshaft while the tensioner
is removed. This could upset the camshaft chain
timing, and damage the valves.
