INSTALLATION
(1) Install the bearing caps so that points to the
timing belt side.
(2) Before installing the bearing cap bolts, check that the,
shank length of each bolt “meets the limit., If, th e limit’
is exceeded, replace the bolt.
Limit (A): Max. 71.1 mm (2.80 in.)
(3) Apply engine oil to the threaded portion
sur-
face of the bolt.
(4) Tighten the bolts to 25 Nm
in ‘the’
tightening sequence.
(5) Make a paint mark on the head of each bolt.
(6) Make a paint mark on the bearing cap at the pos ition
to from the paint mark made on the bolt in
the direction of tightening the bolt.
(7) According to the specified tightening sequence, give a
to turn to each bolt and make sure that the
paint mark onthe bolt and that on the cap are in alignment.
Caution
If the bolt is turned less than proper fastening
performance may not be expected.When
tightening the bolt, therefore, be careful to
a sufficient turn to it.
2. If the bolt is overtightened (exceeding
loosen the bolt completely and then retighten it by
repeating the tightening procedure from step (1).
(8)After installing the bearing caps, make sure that t he crank-
shaft turns smoothly and the end play is correct. I f the
end play exceeds the limit, replacer crankshaft bear-
ings.

(1) Visually check for scratches, rust, and corrosi on.
Use also a flaw detecting agent for the check. If d efects
are evident, correct, or replace.
