Right cuff (from the MGR side)
1. Disconnect the negative battery cable.
2. Apply the parking brake. Raise the front end and place it on supports. Remove the right front wheel.
3. Remove the right front wheel liner (Chapter 11).
4. Turn the accessory drive tensioner clockwise and remove the drive belt from the pulleys. Carefully release the tensioner.
5. When loosening the crankshaft pulley bolt, it is necessary to secure the shaft from slipping. On models with manual transmission, engage the highest gear and have an assistant depress the brake pedal. On models with automatic transmission, remove the cover from the transmission bell. Using a power screwdriver or similar, block the toothed ring of the faceplate when your assistant unscrews the pulley bolt. Do not damage the teeth or adjacent components. Another method of securing is to block the pulley with a metal bar with holes, secured with bolts to the shaft pulley.
6. Remove the pulley bolt and washer. The bolt has been plastically deformed during the previous tightening, so always use a new bolt when installing.
7. Use a puller to pull the pulley off the shaft. If the woodruff key does not hold well in the groove, remove it and save it.
8. Using a screwdriver, pull the cuff out of the MGR cover. Do not damage the cover or the crankshaft. If the cuff is difficult to pull out, carefully drill two diametrically opposite holes in it. Screw self-tapping screws into them and use pliers to pull the cuff out by the screws.
9. Wipe the cuff seat in the cover and the nose of the crankshaft.
10. Lubricate the rim and the sealing edge with clean engine oil and press the seal into place by hand. Tap the seal flush with the cover using a soft-faced hammer and a bushing slightly smaller in diameter than the seal, which should rest on its outer diameter. Be careful not to twist the seal and not to damage it.
11. Lubricate the keyway in the pulley bore. Insert the woodruff key into the keyway on the crankshaft nose, aligning it parallel to the shaft surface.
12. Place the pulley on the shaft, aligning it with the key. Press the pulley onto the shaft using the old bolt and washer. Unscrew the bolt.
13. Screw in a new bolt with a washer and tighten it to the required torque, turning it to the required angle. To prevent the shaft from turning during tightening of the bolt, fix its flywheel using the method described in paragraph 5. Note that the bolt must be tightened in four stages, as specified in the Technical Data.
14. Disassemble the locking device and (on automatic transmission models) install the transmission case cover.
15. Install the main accessory drive belt as shown in chapter 1.
16. Install the right wing liner as described in Chapter 11.
17. Install the right wheel and lower the vehicle.
Left cuff (transmission side)
18. Remove the transmission (Chapter 7A or 7B).
19. Remove the flywheel or faceplate (paragraph 19).
20. Remove the adapter plate from the engine.
21. Using a screwdriver, pull the cuff out of the cylinder block. Do not damage the cuff seat or the crankshaft. If the cuff is difficult to pull out, carefully drill two diametrically opposite holes in it. Screw self-tapping screws into them and use pliers to pull the cuff out by the screws.
22. Wipe the cuff seat and crankshaft.
23. Lubricate the rim and the seal lip with clean engine oil and press the seal into place by hand. Tap the seal flush with the cylinder block using a soft-faced hammer and a bushing of slightly smaller diameter than the seal, which should be supported on its outer diameter. Be careful not to twist the seal and not to damage it.
24. Install the adapter plate onto the cylinder block pins.
25. Install the flywheel or faceplate as described in paragraph 19.
26. Install the transmission as described in Chapter 7A or 7B.
