Refer to “engine bottom side assembly” .
Inspection
- Inspect each upper and lower crankcase bearing for any damage.
- Set the crankshaft onto the upper crank case.
- Install the plastigauge onto each crankshaft journal.
Special tool
(a): 09900–22301 (plastigage (0.025 –
0.076
Mm))
- Mate the lower crankcase with the upper crankcase.
- Tighten the crankshaft journal bolts (m9). Tighten each bolt a little at a time to equalize the pressure in the following two steps.
| Note do not rotate the crankshaft when a piece of plastigauge is installed. |
Tightening torque crankshaft journal bolt (m9): 18 n·m (1.8 Kgf-m, 13.0 Lbf-ft) then turn in 50°
- Remove the lower crankcase and measure the width of compressed plastigauge using the envelope scale. This measurement should be taken at the widest part of the compressed plastigauge. If the oil clearance exceeds the service limit, select the specified bearings from the bearing selection table.
Crankshaft journal oil clearance standard: 0.016 – 0.034 Mm (0.0006 – 0.0013 In)
Crankshaft journal oil clearance service limit: 0.080 Mm (0.0031 In)
Selection
- Check the corresponding crankcase journal i.D.
Codes “a” ([a], [b] or [c]), which are stamped on the rear of the upper crankcase.
