Cap Bolt Outer Diameter Inspection

1. Measure the outer diameters [(a), (b) and (c)] at the position shown in the figure.

a : Value at the end of the smaller diameter of the bolt
b : Value at the end of the smaller diameter of the bolt [opposite side of (a)]
c : Value of the smallest diameter of the smaller of the bolt

2. Obtain a mean value (d) of (a) and (b).
3. Subtract (c) from (d).

Limit [(d) - (c)] 0.08 mm (0.0032 in)

4. If it exceeds the limit (large difference in dimensions), replace the bolt with new one.

Cap Bolt Tightening Torque
First pass 29.4 N-m (3.0 kg-m, 21.7 ft-lb)
Second pass Completely loosen bolts
Third pass 19.6 N-m (2.0 kg-m, 14.5 ft-lb)
Final pass Tighten 90°

Side Clearance
If the measured value exceeds the limit, replace connecting rod, and measure again. If it still exceeds the limit, replace crankshaft also.
