HINT:
If using a standard bearing, replace it with one having the same
number. If the number of the bearing cannot be determined, se-
lect the correct bearing by adding together the numbers in-
printed on the crankshaft and connecting rod, then selecting
the bearing with the same number as the total. There are 5
sizes of standard bearings, marked ”2”, ”3”, ”4”, ”5” and ”6” ac-
cordingly.
