SPIRAL BEVEL PINION SUB ASSEMBLY - SEE FIG. No. 2
8.1
Fit inner and outer bearing cups (31 & 25) into their respective bores in bearing housing (22).
8.2
Press inner bearing cone (31A) onto pinion shaft (32).

Pinion assembly as follows :-
Fit inner bearing spacer (30) large inside chamfer end first, then outer spacer (29) large outside chamfer
outwards onto pinion shaft (32). Feed assembly into position in housing.

pre-load and resultant bearing damage.
