NOTE:
1. Measure the dimensions in the A and B directions
at the position 1 and 2 in the right figure avoiding
the oil hole of the bearing (bush) and calculate
difference from the maximum value of the
crankshaft journal (oil clearance).
2. When replacing the bush, push it up using a
press or the like. At this time, align the oil holes
and push it up until the bush end surface
becomes level with the outside machined surface
of the cylinder block (see the arrow mark in the
right figure).
