Fig. 37 - Front and Rear Axle Drive Cardan Shaft
The front and rear axle drive cardan shaft design is shown in Fig. 38.
Before reassembling the joints, pack lubricant between the working edges of the end
packing. After reassembling the spiders should turn in the bearings smoothly, without jamming.
Check periodically the clearance in the spline joint. Should the clearance exceed 1.2 mm
(front and rear axle drive shafts see in Fig. 37) and 0.55 mm (intermediate shaft and intermediate
axle (rear axle for 4
х
4 trucks) drive shaft), replace the shafts.
When assembling the cardan shaft, see that the arrows stamped on the tube shaft and
sliding fork are positioned one opposite another, and the flanges, forks and balancing plates are
sealed in the same position they had before disassembling. To provide that, mark the parts of the
cardan shaft prior to its disassembling.
Upon replacing the flanges, welded and sliding forks, the cardan shafts should be dy-
namically balanced repeatedly. The disbalance causes shafts vibration, which effects adversely
transmission functioning.
