(i) Measure the Plastigage at its widest point.
Standard oil clearance:
    STD
        .035–.053 mm (0.0014–0.0021 in.)
    U/S 0.25
        .040–.078 mm (0.0016–0.0031 in.)
Maximum oil clearance.
    STD
        .08 mm (0.0031 in.)
    U/S 0.25
        .09 mm (0.0035 in.)

If the oil clearance is greater than maximum, replace the
bearings. If necessary, grind or replace the crankshaft.
HINT: If using a standard bearing, replace with one having
the same number. If the number of the bearing cannot be de-
termined, select the correct bearing by adding together the
numbers imprinted on the connecting rod cap and crank-
shaft, then selecting the bearing with the same number as the
total. There are 5 sizes of standard bearings, marked "1", "2",
"3", "4" and "5" accordingly.
