Measure the Plastigage at its widest point

Standard oil clearance: 0.025 to 0.050 mm (0.000984 to 0.00197 in.)

Maximum oil clearance: 0.070 mm (0.00276 in.)

If the oil clearance is greater than the maximum, replace the bearings If necessary, replace the
crankshaft



If replacing a bearing, replace it with one that has the same number as its respective
connecting rod cap Each bearing's standard thickness is indicated by a 1, 2, 3 or 4 mark on
its surface



Select the correct bearing by adding together the number marks imprinted on the connecting
rod big end and crank pin

Example:

Connecting rod "1" + Crank pin "2" = 3 (Use bearing "3")
