Camshaft Chain Tensioner Removal
This is a non-return type camshaft chain tensioner.
The push rod does not return to its original position
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.
mounting bolts from this position could damage
the camshaft chain and the tensioner.
Once the bolts are loosened, the tensioner must
be removed and reset as described in "Camshaft
Chain Tensioner Installation".
Do not turn over the crankshaft while the tensioner
is removed. This could upset the cam chain timing
and damage the valves.
Loosen the Cap bolt [A].
