GENERAL ENGINE MECHANICAL 6A – 55
6. Piston and Connecting Rod
• Apply engine oil to the cylinder bores, the connecting
rod bearings and the crankshaft pins.
• Check to see that the piston ring end gaps are
correctly positioned.
• Insert the piston/connecting rod assemblies into each
cylinder with the piston ring compressor.
• The front marks must be facing the front of the engine.
5. Connecting Rod Bearing Cap
• Tighten the cap nuts in 2 steps, using angular
tightening method as shown in the following
specifications.
4JG2 N∙m (kg∙m/lb∙ft)
1st Steps 2nd Step
29 (3.0/22) 45° - 75°
4JA1, 4JB1, 4JB1TC N∙m (kg∙m/lb∙ft)
83 (8.5/61)
After tightening the cap nuts, check to see that the
crankshaft rotates smoothly.
4. Piston Cooling Oil Pipe
• Install the piston cooling oil pipe to the cylinder body.
• Tighten the oil pipe bolts and relief valve to the
specified torque.
Oil Pipe Bolt Torque N∙m (kg∙m/lb∙ft)
(1) M8 x 1.25 19 (1.9/14)
N∙m (kg∙m/lb∙in)
(2) M6 x 1.00 8 (0.8/69)
Oil Pressure Regulating
Valve Torque N∙m (kg∙m/lb∙ft)
(3) M16 x 1.5 29 (3.0/22)
NOTE:
Check that there is no interference between the piston
and the oiling jet pipe by slowly rotating the
crankshaft.
