• If necessary, regrind crankshaft journal and select
undersize bearing to use with it as follows.
a. Regrind journal to the following finished diameter.
Finished journal diameter
For M13 engine: 44.7320 – 44.7500 mm (1.7611
– 1.7618 in.)
For M16 engine: 51.7320 – 51.7500 mm (2.0367
– 2.0374 in.)
b. Using micrometer, measure reground journal
diameter.
Measurement should be taken in two directions
perpendicular to each other in order to check for
out-of-round.
c. Using journal diameter measured above and
alphabets stamped on cylinder block, select an
undersize bearing by referring to the following
table.
Check bearing clearance with newly selected
undersize bearing.

Bearing Cap Bolt
Measure each thread diameter bearing cap bolts (1) at
“A” and “B” by using a micrometer (2).
Calculate difference in diameters (“A” – “B”).
If it exceeds limit, replace with new one.
Bearing cap No.1 bolt diameter measurement points
“a”: 60 mm (2.36 in.)
“b”: 90 mm (3.54 in.)
Bearing cap No.1 bolt diameter difference
Limit: (“A” – “B”): 0.2 mm (0.008 in.)
Sensor Plate Inspection
