Eccentricity test
Install 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.
If the runout exceeds the specified values, straighten the shaft under a press or replace it.
Spline connection
Check the gap in the splined joint of the sliding fork of the front and rear shafts. The maximum permissible circumferential clearance along the average diameter of the spline is 0.30 mm.
Check plug in plug 5 (rice. 3-48), the condition of the clip 7 and the gland 6 of the sliding fork. If necessary, replace the seal, and if damaged, replace the clip.
Cardan joints
Check the condition of the bearing housings, needles, cross spikes, seals, end washers.
If the bearing housings, spider needles and spikes, or seals or end washers are damaged or worn, replace the spider assembly with bearings.
The bore diameter of the needle bearing yoke must not exceed 28.021 mm.
If the working surfaces of the intermediate shaft hinge parts are more than 0.1 mm damaged or worn, replace the hinge assembly.
Elastic coupling
Check the condition of the rubber elements of the flexible coupling. If there are cracks or delamination of rubber from metal liners, replace the flexible coupling.
Flexible coupling flange
Check the condition of the centering sleeve of the flexible coupling flange. If the bushing is worn or damaged, replace it.
