| t
| Lubricate all bearings (except tapered roller bearings) with gear oil before installing in gearbox. |
| t
| Heat inner races of tapered roller bearings to approx. 100°C before installing. Press in onto stop when installing so there is no axial clearance. |
| t
| Heat inner races of needle bearings and roller bearings to max. 130 °C. |
| t
| Do not interchange the outer or inner races of bearings of the same size (the bearings are paired). |
| t
| If required, renew the tapered roller bearings on one shaft together and use new bearings from a single manufacturer. |
| t
| Check the double angular contact ball bearing → Item for wear (running noises); pinion shaft remains installed and differential is removed. “The bearing should not catch and should run smoothly when rotating the pinion shaft”. |
