21. REMOVAL OF AUTO TENSIONER
(1) Turn the crankshaft clockwise and align the timing
marks so as to bring the No. 1 cylinder to compression
top-dead-centre position.
At this time the timing marks of the camshaft sprocket
and the upper surface of the cylinder head should
coincide, and the dowel pin of the camshaft sprocket
should be at the upper side.
CautionThe crankshaft must always be rotated clockwise.

(1) Check the auto tensioner for possible leaks and replace as*
necessary.(2) Check the rod end for wear or damage and replace as
necessary.(3) Measure the rod protrusion. If it is out of specification,
replace the auto tensioner.
Standard value: 12 mm
(.47 in.)
(4)Using a vise with soft jaws push in the auto tensioner rod. Ifthe rod can be easily retracted, replace the auto tensioner.
You should feel a fair amount of resistance when pushing
the rod in.
,J-Caution
’1. Clamp the auto tensioner in the vise so it maintains
a level position.
2. If the plug at the bottom of the auto tensioner
protrudes, surround it with a plain washer as
illustrated to prevent the plug from being in direct
contact with the vise.
