Service and Torque Specifications

SERVICE SPECIFICATIONS

Standard clearance:
STD: 0.026 - 0.040 mm (0.0010 - 0.0016 inch)
U/S 0.25: 0.025 - 0.061 mm (0.0010 - 0.0024 inch)
Maximum clearance:
STD: 0.06 mm (0.0024 inch)
U/S 0.25: 0.08 mm (0.0031 inch)

If the oil clearance is greater than maximum, replace the bearings. If necessary, grind or replace the crankshaft.





HINT: If using a standard bearing, replace with one having the same number. If the number of the bearing cannot be determined, select the correct bearing by adding together the numbers imprinted on the cylinder block and crankshaft, then refer to the table for the appropriate bearing number. There are 5 sizes of standard bearings, marked "1", "2", "3", "4" and "5" accordingly.





EXAMPLE: Cylinder block "3" (A)
+ Crankshaft "4" (B)
= Total number 7 (Use bearing "3")





EXAMPLE: Cylinder block "3" Crankshaft "4" - Use bearing "3"

TIGHTENING SPECIFICATIONS

INSTALL MAIN BEARING CAP BOLTS

HINT:
^ The main bearing cap bolts are tightened in 2 progressive steps (steps (b) and (d)).
^ If any of the main bearing bolts break or deform, replace them.

a. Apply a light coat of engine oil on the threads and under the heads of the main bearing cap bolts.

Main Bearing Cap Bolts Tightening Sequence:

b. Install and uniformly tighten the 14 main bearing cap bolts, in several passes, in the sequence shown.

Torque: 44 Nm (33 ft. lbs.)

If any one of the main bearing cap bolts does not meet the torque specification, replace the main bearing cap bolt.





c. Mark the front of the main bearing cap bolt head with paint.
d. Retighten the main bearing cap bolts 90° in the numerical order shown above.
e. Check that the painted mark is now at a 90° angle to the front.
f. Check that the crankshaft turns smoothly.
