Maintenance of brakes operating in oil
Adjustment operations of “wet” brakes are similar to those of dry brakes: travel of pedals
110…120 mm upon effort of 300 N on one pedal is adjusted with bolts 25, (Figure 4.144).
Oil level in brakes’ bodies must reach edge of check plugs openings 22, (Figure 4.145), on face
walls of bodies. Operations of changing oil in brakes’ body must be carried out at the same time
with changing oil in transmission. Grade of oil used for brakes must be the same as for
transmission. To drain oil from brakes’ body drain plugs (10) are provided in the bottom. (Figure
4.145). Level of oil in bodies is checked each
500 hours of tractor operation.
.
Attention! Operation of brakes without oil or insufficient level of oil is not permitted.
