Cylinder Head Assembly

CYLINDER HEAD






Tighten the cylinder head bolts in the following sequence, using the 4 step torque-turn method. Tighten according to the following torque values:
Step 1: All 61 Nm (45 ft. lbs.)
Step 2: All 88 Nm (65 ft. lbs.)
Step 3: All (again) 88 Nm (65 ft. lbs.)
Step 4: + 90° Turn Do not use a torque wrench for this step.

Bolt torque after 90° turn should be over 122 Nm (90 ft. lbs.) in the tightening direction. If not, replace the bolt.

Install three inner timing cover to cylinder head bolts.
Tighten bolts 54 Nm (40 ft. lbs.).

HEAD BOLT RE-USABILITY

The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced.






SURFACE VARIATION

Cylinder head must be flat within:
Standard dimension = less than 0.05 mm (0.002 inch.)
Service Limit = 0.2 mm (0.008 inch.)
Grinding Limit = Maximum of 0.2 mm (0.008 inch.) is permitted.

CAUTION: 0.20 mm (0.008 in.) MAX is a combined total dimension of the stock removal limit from cylinder head and block top surface (Deck) together.
