Main Bearing Cap Torque

DIMENSIONS
Bearing Cap Bolt Shank Length: 71.1 mm (2.80 inch)

TIGHTENING SPECIFICATIONS
1. Install the bearing caps so that the arrow 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 the limit is exceeded, replace the bolt. The maximum limit (A) is 71.1 mm (2.80 inch).
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 - 100° clockwise (from the paint mark).
7. According to the specified tightening sequence, give a 90 - 100° turn to each bolt and make sure that the paint mark on the bolt and that on the cap are in alignment.

NOTE:
- 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.
- If the bolt is 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 crankshaft turns smoothly and the end play is correct. If the end play exceeds the limit, replace No. 3 crankshaft bearings.
Standard value: 0.05 - 0.18 mm (0.0020 - 0.0071 inch).
Limit: 0.25 mm (0.0098 inch).
