Removing propeller shaft
1. Lift and fix a car. 2. Remove the lower engine protection. 3. In order not to disturb the balance in the back of the propeller shaft assembly, mark its position in the following locations:
| Fig. 6.16. Places labeling rear propeller shaft (arrow): 1 - the rear propeller shaft; 2 - the gauge of frequency of turns on a differential
|
- The position of the propeller shaft flange (Fig. 6.16, arrow) on the differential; - The position of the propeller shaft, and disk damper hinge relative gearbox and each other. 4. Remove the rear part of the exhaust system.
| Fig. 6.15. Details driveline: 1 - centering sleeve; 2, 10 - elastic coupling; 3 - bolt 45 Nm; 4 - front axle; 5 - locking nut; 6 - rubber sleeve; 7 - the bearing; 8 - bolt 25 Nm; 9 - rear shaft
|
5. Loosen the screws 8 (see. Fig. 6.15) fastenings of the support bearing 7, before that having marked position. 6. Remove the bracket from the tunnel. 7. Remove the protection of the exhaust system. 8. Loosen the lock nut SW 41/42 on the sliding part (front and back) the propeller shaft. 9. Remove the propeller shaft from the flange gearbox so that the disc was left hinge shaft (bolt head SW 15 nut SW 17). 10. Loosen the driveshaft to the differential output (three bolts SW 15 nut SW 17) so that the shaft remains constant velocity joints. 11. In the case of kick is the differential output shaft to release his small impacts. 12. Gently slide along the shaft of the propeller and remove the flange. 13. The rear portion of the shaft leave hanging down. 14. Remove the bolts securing the support bearing 8. 15. Remove the propeller shaft from the central tunnel at the bottom of the car. 16. Xpress centering sleeve couplings 1 of 2 and 10. 17. When reinstalling the plugs fill the cavity multi-purpose grease. 18. When reinstalling the front axle capitalize on first flange gearbox, following the marking. To fix, use new nuts. 19. Install without wrapping to the end support bearing. 20. Observing marking tighten the rear shaft. Use new self-locking nuts and tighten them to a torque of 45 Nm. 21. Tighten the front shaft to the flange to 25 Nm. 22. Tighten the support bearing 25 N ?� m. Rear-wheel drive vehicle must be at the same time on the ground. If the rear axle is unloaded, tighten mounting only if previously applied the appropriate tags.
| Fig. 6.17. Tightening fixing nut spanner SW 41. Observe the tightening torque 30-40 Nm, otherwise the propeller shaft will buzz

23. Tighten the lock nut SW 41/42 torque 30-40 Nm (Fig. 6.17).
PRACTICAL ADVICE Noises in the propeller shaft Vibration and buzz indicate an imbalance propeller shaft, and the absence of the balancing plates on the shaft leads to the conclusion that the balance is broken. Both the shaft carefully balanced in relation to each other. Dismantling the propeller shaft without first marking the starting position violates the balance. The imbalance of progress is also possible due to breakage or tearing of the elastic circular joints (constant velocity joints). Fragility fixing centering sleeves indicates a deterioration of joints. Also unacceptable expansion of the production of the fixing holes in the flanges of gearbox and reducer. Whistling sound may be due to worn or a failed thrust bearing. Scrape and rattle usually result from too much play in the connection of two parts of the cardan shaft or dowel bushings are insufficient lubrication. |
