4.3.1. Possible malfunctions of cardan transfer, their reason and methods of elimination

Cause of defect
Elimination method
Knock in cardan transfer at start-off from the place, at sharp dispersal or gear shifting
1. Weakening of tightening of bolts and nuts of fastening
elastic coupling and flanges of cardan hinges
1. Tighten nuts the moments specified in the appendix
2. The increased district gap in shlitsevy connection of the forward driveshaft
2. Check gap size; if it is more than 0,30 mm - replace worn-out details
3. The increased gap in bearings of cardan hinges
3. Repair hinges with replacement of worn-out details
Noise and vibration of cardan transfer
1. Deformation of driveshafts
1. Correct on the press or replace shaft
2. Discrepancy of assembly tags of a forward shaft and
corresponding coupling
2. Remove cardan transfer and achieve coincidence of the tags put when dismantling
3. Imbalance of driveshafts
3. Check balancing; at the imbalance exceeding 2,15 N of mm (220 гс mm), act as it is described in the subsection "Balancing of Shaft"
4. Wear or damage of the aligning plug of a flange of the elastic coupling and the aligning ring of a secondary shaft of the transmission
4. Replace a flange of the elastic coupling assembled with the plug and the aligning ring of a secondary shaft
5. The raised gap in the bearing of an intermediate support
5. Replace the bearing
6. Damage of an intermediate support
6. Replace a support
7. Weakening of tightening of nuts of fastening of a cross-piece
to a car body
7. Tighten nuts of fastening of a cross-piece
8. The raised gap in bearings of cardan hinges or jamming of hinges
8. Repair hinges with replacement of worn-out details
9. Weakening of a holder of an epiploon of a flange of the elastic coupling
9. Draw in an epiploon and press out its holder; at leak of lubricant replace an epiploon
10. Weakening of a nut of fastening of a fork of the forward driveshaft
10. Disconnect a forward shaft from back and tighten a nut then fuller a nut
11. Insufficient lubricant of shlitsevy connection
11. Grease shlitsevy connection with FIOLV1 lubricant
Lubricant leak
1. Weakening of a holder of an epiploon of a flange of the elastic coupling, wear of consolidation
1. Draw in an epiploon and press out its holder, replace a worn-out epiploon
2. Damage or wear of epiploons of cardan hinges
2. Disassemble hinges and replace epiploons
