HINT:

If replacing a standard bearing, replace it with one that has the same number If the number of the
bearing cannot be determined, select the correct bearing by adding together the numbers imprinted
on the connecting rod cap and crankshaft Then select the bearing with the same number as the
total There are 6 sizes of standard bearings, marked 2, 3, 4, 5, 6 and 7

EXAMPLE:

Connecting rod cap "3" + Crankshaft "1" = "4" (Use bearing "4")
