The steering hydraulic cylinder consists of a body 3 (figure3.14.5), a rod 4, a piston
1, a cover 6 and a cap nut 8. The piston is fixed on the rod with a nut 15, which is locked
by punching of the land in rod 4 slots. In eyes of the body and the rod, spherical bearings
7, that have channels in the inner race for lubrication of friction surfaces through the oiler
in the pin, are installed. In the cover 6 a seal 9 (wiper seal), rod guides 13, that exclude
friction of the rod and the cover, and rod packings 10 are installed. An integrated seal 14,
that excludes friction of the piston and cylinder liner, is mounted on the piston.

The oil tank of a welded design with a 6L capacity is mounted behind the storage
batteries. It has an in-built drain filter 2 (figure 3.14.6) with a replaceable paper filtering
element of 25 micron fineness. Oil is filled through a filler neck with a plug 3. The oil filter is
equipped with a safety valve 5. Oil lever is checked by means of a dipstick 4. For oil drain
there is a drain plug 1
