4.2.9.2 Track formation for rear wheels mounted on bevel hubs

By order the tractor rear wheels can be mounted on bevel hub groups which consist
of split conic bushings 3 and 4 (figure 4.2.7) and hub group housing 2.
The bushings are tightened into the hub group housing with six bolts 1 (М20) with a
torque from 360 to 450 Nꞏm, thus clenching the semi-axle.
1 – tie bolts; 2 – hub group housing; 3 – upper bushing; 4 – lower bushing; 5 – dis-
mounting holes.
