Removal and disassembly
Separate the pendulum lever from the ball pins of the middle and side rods by unpinning and unscrewing the nuts beforehand and removing the ball pins from the lever sockets with a puller 67.7824.9516. Then turn away bolts of fastening of an arm to a side member of a body and remove an arm.
Fix the bracket in a vice, unpin and unscrew the nut 4 (pic. 5-12), then remove washers 3 and 6 and pendulum arm 1 complete with axle 9, washer 10 and self-locking nut 11, remove seals 7 and press out bushings 8.
Pic. 5-12. Section of the pendulum arm bracket:
1 - pendulum lever; 2 - bracket body; 3 - washer; 4 - adjusting nut; 5 - cotter pin; 6 - top washer; 7 - sealant; 8 - bushing; 9 - axis of the lever; 10 - bottom washer; 11 - self-locking nut.
Examination
Check the condition of the pendulum arm axle bushings; if you find an ovality or an unacceptable gap between them and the axle, then replace the bushings with new ones. At the same time, sealing rings 7 are also replaced.
Check the axle for ovality and damage, replace it with a new one if necessary. Make sure the pendulum arm is not deformed, otherwise replace it with a new one.
Assembly and installation
Before assembly, lubricate the pendulum arm axle bushings and fill the space between them with Litol-24 grease. Assembly order of the pendulum arm bracket, reverse to disassembly.
If the axle 9 has been replaced, then tighten the self-locking nut 11 of the lever fastening with a torque wrench.
Washer 6 is installed with bulges up.
After tightening the nut 4, the lever in the horizontal position must not rotate under its own weight. It should rotate under the action of a force of 9.8-19.6 N (1-2 kgf), attached at its end.
If nut 4 is overtightened, unscrew it, lift washer 6 and tighten again.
After securing the bracket to the side member with bolts with self-locking nuts and flat washers, tighten them with a torque wrench.
Connect the ball pins of the rods to the pendulum lever.
