to support the timing
sprocket and maintain tension on timing chain.
(Fig. 29)
The timing chain must not be allowed to become
slack during this operation. The timing cover will
have to be removed to release the tensioner if the
chain
is
slackened accidentally.
The dummy bearing (A) will only be used if the
crankshaft has to be turned, for example, when
"piston and liner" assemblies are changed to
prevent any alteration in the valve timing.
