original fitted location, DO NOT DROP. Screw
each bolt by hand into oil rail.
CAUTION: It will be necessary to
temporarily remove cylinder liner retainer
clamps LRT-12-144 in order to test the
bolt used with the retainer clamp. Retainer
clamps should only be removed one at a time
and replaced immediately bolt test is completed.
Take great care not to rotate crankshaft or
disturb cylinder liners whilst clamps are
removed.
