Usage:
Start By:
a. remove valve cover
1. Remove six bolts (1) and washers from the rocker shaft.
2. Remove the rocker shaft assembly (2) from the cylinder head.
3. Remove push rods (3) from the engine.
Install Rocker Shaft And Push Rods
1. Loosen the adjusting screws (1) on the rocker arms for valve clearance. This will prevent a bent valve or push rod at installation.
2. Install the push rods (3).
3. Put rocker shaft assembly in position on the cylinder head.
4. Put 2P2506 Thread Lubricant on the threads of all rocker shaft mounting bolts except bolt (10). Install bolts in the rocker shaft assembly.
NOTE: Make sure the rocker arms are on all the push rods.
| NOTICE |
|---|
The dowels (4) on each end of the rocker shaft assembly must be in alignment with the holes in the cylinder head assembly. If the dowels and holes are not in alignment when the rocker shaft assembly is tightened, damage to the rocker shaft assembly will be the result. |
5. Tighten the bolts for the rocker shaft as follows:
a. Tighten bolts (5-10) in number sequence to a torque of 155 N·m (115 lb.ft.).
b. Tighten all the bolts again in number sequence to a torque of 250 ± 17 N·m (185 ± 13 lb.ft.).
c. Last, tighten bolts again in number sequence (hand tighten only) to a torque of 250 ± 17 N·m (185 ± 13 lb.ft.).
6. The assembled length of springs at both ends of the rocker shaft must be 1.50 ± 0.25 mm (.059 ± .010 in.). Remove or install washers behind springs to change the assembled length of the springs.
7. Make adjustments until the intake valve clearance is .038 mm (.015 in.) and the exhaust valve clearance is 0.64 mm (.025 in.). See VALVE CLEARANCE SETTING in TESTING AND ADJUSTING. Tighten the locknuts (2) for the adjusting screws (1) to a torque of 29 ± 7 N·m (21 ± 5 lb.ft.).
