15

Install constant speed gear 2 (5)

16

Heat up tapered roller bearing (4) to approx. 100 °C, and push onto main shaft (12)

 Grease the tapered roller bearing (4) with multipurpose grease.

*BR00.45-Z-1008-06A

17

Determine shim (3) for axial play of tapered roller bearing of constant speed gear 2 (5) on main shaft (12)

 If checks show the axial play to be OK, the correct shim (3) is already installed.
