- 3. Tighten the bolt to 25 Nm (2.5 m·kgf, 18 ft·lbf).
- 4. Tighten the bolts 1-7 and 10 to 115°-125° and bolts 8 and 9 to 130°-140°.
Connecting rod cap bolt
Use new bolts.
- 1. Apply Molybdenum-disulfide grease to bolt thread and cap/nut mating surface.
- 2. Tighten the bolt to 20 Nm (2.0 m·kgf, 14 ft·lbf).
- 3. Retighten the bolt further to reach the specified angle of 145°-155°.
Crankcase bolt (main journal)
- 1. Lubricate the bolts thread, mating surfaces and washers with engine oil.
- 2. First, tighten the bolts to approximately 30 Nm (3.0 rnrkgf, 22 ft·lbf) with a torque wrench.
- 3. Loosen all the bolts one by one following the tightening order and then tighten them to 18 Nm (1.8 mrkgf, 13 ft·lbf) again.
- 4. Retighten the bolts further to reach the specified angle of 60°.
