Connecting Rod Bolts :
1st
tightening torque : 5 N · m (4 lb · ft) [0.5 kgf · m]
2nd tightening torque : 10 N · m (7 lb · ft) [1.0 kgf · m]
6. Tighten connecting rod bolts 7 in two steps to specified
torque.
28) Inspection of Crank Pin Oil Clearance
1. Clean crank shaft 1 and connecting rod parts 2 and 3.
2. Place cylinder block upside down on the work bench.
Install piston 4 to connecting rod 2, and then, install the
assembly to cylinder block.
3. Install crank shaft 1 to cylinder block.
4. Place a commercially available plasti-gauge 5 on the

Do not move connecting rod and crankshaft until
oil clearance measurement is completed.
· Be sure to install the cap 3 in original position
(direction).
· Be sure that connecting rod "▲ " mark a
points crank shaft flywheel side.
7. Remove connecting rod cap 3 and measure width of
crushed plasti-gauge 5 on the crank pin 6. Replace
connecting rod 2 or crank shaft 1 if the measurement
(converted value) is over the limit.
Big End Oil Clearance : Converted value
0.015 - 0.041 mm (0.00059 - 0.00161 in)
Functional Limit :
0.060 mm (0.00236 in)
Do not attach piston rings in this step.
When installing, bring projection of bearing to notch
of cylinder block.
