- There is only one type of main bushing housing

hole in the crankcase

The standard bushing diameter after driving is var-

iable on the basis of a coupling selection.

- The bushing housings in the crankcase are avail-

able in two categories, Cat. 1 and Cat. 2, as are

the crankshafts.

- The main bushings are available in three thick-

ness categories, identified by colour markings, as

shown in the table below.

Match the shaft with two category 1 crank webs

with the category 1 crankcase (or cat. 2 with cat.
