1D-80 Engine Mechanical:
2) Set the crankshaft onto the upper crank case.
3) Install the plastigauge onto each crankshaft journal.
Special tool
(A): 09900–22301 (Plastigage (0.025 – 0.076
mm))
4) Mate the lower crankcase with the upper crankcase.
5) 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°
6) 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)
