Sequence for tightening the camshaft gear |
Use the following procedure to tighten the camshaft bolts.
- Lightly lubricate the O-ring seal on the outside of the sealing plate of the camshaft with a 50/50 mixture of 8T-2998 Lubricant and engine oil that is clean.
- Apply 9S-3263 Thread Lock Compound to the three bolts for the sealing plate of the camshaft.
- Tighten the three sealing plate bolts on the camshaft to the following torque.
Torque ... 12 ± 3 N·m (9 ± 2 lb ft)
- Tighten the camshaft bolts in the following sequence.
Refer to Illustration 1 for the numbering of the bolts. ... 1, 4, 2, 5, 3, 6, 1, 4
Torque ... 240 ± 40 N·m (177 ± 30 lb ft)
