Crankshaft: Service and Repair

REFER TO FIGURE FOR REMOVAL/INSTALLATION


INSTALLATION POINT:
BEARING CAP / BEARING CAP BOLT INSTALLATION

(1) Install the bearing caps so that their arrows are directed to the timing belt side.





(2) Before 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 (2.79 in.)

(3) Apply engine oil to the threaded portion and bearing surface of the bolt.





(4) Tighten the bolts to 25 Nm (18 ft.lbs.) in the specified tightening sequence.
(5) Make a paint mark on the head of each bolt.
(6) Make a paint mark on the bearing cap at the position 90° to 100° from the paint mark made on the bolt in the direction of tightening the bolt.
(7) According to the specified tightening sequence, give a 90° to 100° turn to each bolt and make sure that the paint mark on the bolt and that on the cap are in alignment.

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 has been overtightened (exceeding 100°), 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 the crank shaft turns smoothly and the end play is correct. If the end play exceeds the limit, replace crankshaft bearings.

Standard value: 0.05-0.18 mm (.0020-.0071 in.)

Limit: 0.25 mm (.0098 in.)
