C Bearing cap/bearing cap bolt installation
(1) Install the bearing caps so that their arrows are
positioned on the timing belt side.
(2) When installing the bearing cap bolts, check that the
shank length of each bolt meets the limit. If the limit is
exceeded, replace the bolt.
Limit: Max. 71.1 mm (2.799 in.)
(3) Torque the bearing cap bolts to 2.5 kgf•m (18.1 lb•ft)[25
N•m] and, from that position, retighten them 1/4 (90°)
turns more.
Caution:
1) If the bolt is turned less than 90°, proper fastening
performance may not be expected. When tightening the
bolt, therefore, be careful to give a sufficient turn to it.
2) If the bolt is over tightened (exceeding 100°), loosen the
bolt completely and then retighten it by repeating the
tightening procedure from step (1).
(4) After installing the bearing caps, make sure that the end
play is correct. If the end play exceeds the limit, replace
the crankshaft bearings.
Standard value: 0.05 to 0.25 mm (0.0020 to 0.0098 in.)
Limit: 0.4 mm (.016 in.)
