Details of disassembled drive shaft with sprocket joint inside
1 - retaining ring; 2 - internal hinge of equal angular velocities; 3 - retaining ring; 4 - hinge sprocket; 5 - clamping bands of rubber cuffs; 6 - rubber cuff; 7 - drive shaft
The CV joint on the wheel side, as well as the ball joint of the right shaft of the car with the injector, cannot be disassembled. You can only replace the rubber cuffs. The internal constant velocity joint of the left shaft of the injection engine, as well as both shafts of the carburetor engine, can be repaired as described below. It is also possible to disassemble the thrust bearing to replace the ball bearing located there if it is broken.
When disassembling the tripod joint, proceed as follows, guided by illustration:
1. Clamp the drive shaft in a vise and remove both rubber bands. Tie-down straps can be thrown away immediately.
2. Mark the position of the pivot housing relative to the drive shaft and remove from the end of the shaft.
3. While holding the drive shaft in a vise as shown in the illustration, paint the sprocket and shaft with paint.
4. Remove retaining ring (3) from the end of the shaft (7). Discard the retaining ring immediately.
5. Position the drive shaft under the press so that the pivot rests on the press table and press the shaft out of the sprocket. Hold the shaft from below, otherwise it will fall down.
6. Remove the rubber collar from the shaft. Clean all parts and check carefully. The pivot sprocket is not disassembled and must be replaced as a set if the needle roller bearing is broken. Check for wear on the splines inside the pivot sprocket before reinstalling the part. When assembling the drive shaft, proceed as follows:
7. Put a new small clamp on the shaft of a new cuff.
8. Clamp the drive shaft in a vise using chocks.
9. Put the sprocket on the shaft in accordance with the designations (illustration below). If a new asterisk is used, it doesn't matter. The sprocket has a grip on the inside on one side, and this side must be put on the shaft first.
Before removing the tripod joint, mark the shaft and joint with paint.
10. Drive the pivot sprocket onto the shaft with a light metal hammer and insert a new circlip (3). The rounded side of the retaining ring faces the sprocket.
11. Now fill the hinge with grease. Depending on the car model, the amount of lubricant is different. At the shaft of a car with a 1.6 liter engine, the amount of lubricant is 175 - 185 g; on all other vehicles 205 - 215 g. Press grease into the joint and install the cuff.
12. Install the large clamp and pull tight. Then fold the end over so that it goes between the staples and fold both staples onto the tape.
13. Stretch the cuff until the size "L" (see illustration below) on a car with a 1.6 liter engine will not be equal to 89 - 91 mm or on other cars 96 - 98 mm. Place the small clamp in the same way.
Stretch the cuff on the side of the gearbox until the size "L" will not match the value in the text.
14. Pictured on illustrations drive shaft constant velocity joint (Bearfield hinge) can be replaced like this:
15. If the joint needs to be replaced, remove the ABS gear rotor from the shaft.
16. After loosening both clamps, slide the joint collar back on the shaft.
17. Remove the retaining ring from the groove (8) using special forceps. Discard the retaining ring immediately, as it should not be used a second time.
18. Mark the mounting position of the hinge on the shaft with a felt-tip pen and remove the hinge from the shaft. If the joint needs to be replaced, it can be knocked down with a hammer while holding the shaft in a vise. Otherwise, it should be carefully knocked down with a light metal hammer.
19. Thoroughly clean the drive shaft and clamp the shaft again in a vise.
20. Slide the rubber boot over the shaft, with the large opening facing out.
21. Put the hinge on the shaft. If the same parts will be used, the marks must be aligned again.
22. Thread the old driveshaft nut until the end is flush and tap the pivot onto the shaft with a light metal hammer until the circlip can be snapped onto the inside with sharp pliers.
23. Fill the joint with the required amount of grease. On a car with a 1.6 liter engine, the amount of lubricant is 80-110 g, on other engines 110-130 g.
24. Install the large clamp and pull tight. Then fold the end over so that it lies between the staples, and fold both staples over.
25. Stretch the cuff until it reaches the specified length (see illustration).
26. Attach the small clamp in the same way. Check that both clamps fit well.
Repair of the right shaft of a car with an injection engine
Separate parts of the drive shaft with thrust bearing
1 - bolt, 30-40 Nm; 2 - bolt, 25-35 Nm; 3 - bolt, 45-60 Nm; 4 - dustproof ring; 5 - retaining ring; 6 - bolt, 16-19 Nm; 7 - support console; 8 - thrust bearing housing; 9 - ball bearing; 10 - retaining ring; 11 - dustproof ring; 12 - intermediate shaft; 13 - retaining ring; 14 - balls; 15 - inner race of the bearing; 16 - separator; 17 - cuff clamps; 18 - cuff
The outer hinge of this shaft is of the same design as shown in illustrations. This also applies to the shaft. shaft end (7) is located, however, not in the tripod joint, but in the ball joint. The illustration above shows additional details of such a shaft, which is guided by a thrust bearing.
1. Remove the collar straps and clean the inside of the shaft and joint from grease. If the shaft and joint are reassembled (e.g. when replacing a cuff), mark the connection as appropriate.
2. Clamp the shaft firmly in a vise and tap the joint with a light alloy hammer as shown in the illustration below. Hit different points on the circle.
Knocking down the hinge of equal angular velocities.
3. Remove the hinge and remove a rubber cuff.
4. Wrap the end of the shaft with duct tape and slide the collar with a small collar over the shaft.
5. Fill the hinge with grease in the amount of 175 - 185 g and install the cuff. At the small end, the cuff should sit well in the groove, as shown in the illustration. Tighten both cuff clamps well and fix by bending the staples.
The cuff should sit well in the groove in the place indicated by the arrow.
Thrust bearing replacement
The thrust bearing must first be unscrewed from the mount before it can be disassembled.
1. Knock the outer dust cover off the shaft with a rod. Dust rings (4) (see illustration) shoot together.
2. Use a screwdriver to remove the dust ring (11) from the bearing housing and open and remove the retaining ring underneath using special pliers.
3. Place the bearing housing under the press and press out the shaft.
4. Knock out the bearing (9) from the body. Assembly is carried out in the reverse order. Carefully hammer the dust rings on both sides with a small drift without damaging them.
