Note
t | Refer to technical data when installing new gears or final drive gear set → 6-speed manual gearbox 0A3, four-wheel drive; Rep. Gr.00. |
t | Always renew the double angular contact ball bearing → Item when renewing the pinion shaft (final drive gear set) → Item. |
t | Lubricate all needle bearings and synchro-rings with gear oil before installing. |
t | When renewing synchro-rings, renew inner ring, intermediate ring and synchro-ring for the corresponding gear together. |
t | If synchro-rings are not being renewed, make sure they are re-installed on the same gear. Do not interchange synchro-rings for reverse gear with synchro-rings for 1st and 2nd gear → Fig.. |
