Tightening Specifications

Tighten cylinder head bolts using the following procedure.
a. Tighten all bolts to 39 Nm (29 ft. lbs.).
b. Tighten all bolts to 78 Nm (58 ft. lbs.).
c. Loosen all bolts completely.
d. Tighten all bolts to 34 to 44 Nm (25 to 33 ft. lbs.).






e. Turn all bolts 90 to 95 degrees clockwise with angle wrench tool No. KV10112100, or equivalent.






NOTE: If an angle wrench is not available, mark all cylinder head bolts on the side facing engine front. Then, turn each cylinder head bolt 90 to 95 degrees clockwise.

f. Turn all bolts another 90 to 95 degrees clockwise.
g. Ensure that paint mark on each bolt faces the rear of the engine.

NOTE: Do not turn any bolt 180 to 190 degrees clockwise all at once.







a. Arrange bolts (size and length), per the illustration.
(Bolt type A): M6 x 53.8mm (2.12 inch.)
(Bolt type B): M6 x 37 mm (1.46 inch.)
(Bolt type C): M8 x 35 mm (1.38 inch.)
(Bolt type D): M6 x 64 mm (2.52 inch.)









b. The tightening procedure is:
STEP 1:
RH camshaft: Tighten bolts Nos. 9 and 10, in that order, then tighten bolts (1 - 8) in numerical order to 2 Nm (17 inch lbs.).
LH camshaft: Tighten bolts Nos. 11 and 12, in that order, then tighten bolts (1 - 10) in numerical order to 2 Nm (17 inch lbs.).
STEP 2:
Tighten bolts in numerical order to 6 Nm (52 inch lbs.).
STEP 3:
Tighten bolts in numerical order, bolts type (A) (B) (D) to 9.8 - 11.8 Nm (7.2 - 8.7 ft. lbs.) and bolt type (C) to 18 - 25 Nm (13 - 19 ft. lbs.).












Connecting Rod Bolts
1st Pass 14 - 16 Nm (10 - 12 ft. lbs.)
2nd Pass [1] 60 - 65° clockwise







Tighten main bearing bolts all bolts to 26 to 32 Nm (20 to 24 ft. lbs.).






Turn all bolts 75 to 80 degrees clockwise with angle wrench tool No. KV10112100, or equivalent.
Loosen all bolts completely.






Tighten all bolts to 32 to 38 Nm (24 to 28 ft. lbs.).
Turn all bolts 45 to 50 degrees clockwise with angle wrench.
If an angle wrench is not available, mark all bearing cap bolts on the side facing engine rear. Then, turn each bolt specified degrees clockwise. Confirm angle of degrees with a graduator, not by eye measurement.
After securing bearing cap bolts, make sure crankshaft turns smoothly by hand.
