Checking eccentricity

Install the front (rear) cardan shaft in the centers and, turning it, check the runout of the pipe, which should not exceed:

0.5 mm at a distance of 50 mm from the end welds;
0.3 mm in the middle part.

If the runout exceeds the specified values, straighten the shaft under a press or replace it.

Splined connection

Check the clearance in the splined joint of the sliding fork of the front and rear shafts. The maximum permissible circumferential clearance for the average diameter of the splines is 0.30 mm.

Check for plug 5 (fig. 3-48), condition of the sleeve 7 and the seal 6 of the sliding fork. If necessary, replace the seal, and if damaged, the sleeve.

Cardan joints

Check the condition of the bearing housings, needles, crosspiece pins, seals, and end washers.

If the bearing housings, crosspiece needles and pins, as well as seals or end washers are damaged or worn, replace the crosspiece assembly with bearings.

The diameter of the fork hole for the needle bearing should not exceed 28.021 mm.

If the working surfaces of the intermediate shaft joint parts are damaged or worn by more than 0.1 mm, replace the joint assembly.

Flexible coupling

Check the condition of the rubber elements of the elastic coupling. If there are cracks or separation of the rubber from the metal inserts, replace the elastic coupling.
