t
| Use a micrometer to measure the shims at several points. Tolerance variations make it possible to obtain the exact shim thickness required. |
t
| Check for burrs and damage. |
t
| Do not install shims which are damaged or not in perfect condition. |
t
| Install needle bearings, ball sleeves and roller bearings so the lettering (side with thicker metal) faces towards the installing tool. |
t
| Lubricate all bearings in gearbox with gear oil when installing. |
t
| Use inductive heater -VAS 6414- to heat inner races of tapered roller bearings to approx. 100°C before installing. Press home 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. |
Gear wheels, synchro-hubs, inner races for selector gears |
t
| Before installing, heat inner races for selector gears to approx. 100° C using inductive heater -VAS 6414-. |
t
| Use inductive heater -VAS 6414- to heat gear wheels and synchro-hubs to approx. 100°C before installing. Press home onto stop when installing so there is no axial clearance. |
t
| Note correct installation position. |
t
| After installing, check that 1st to 6th speed selector gears have an axial clearance of 0.15 ... 0.50 mm and check that they rotate freely. |
