1 — adjusting screw; 2 — dipstick; 3 — locknut.
Fig. 8.4.33 – Adjust valve clearance.
Operation 39. Check and adjust axial preload in pivot tapered bearings
Check and, if necessary, adjust the axial preload in pivot tapered bearings, as described in
5.6.4 Checking and adjusting axial preload in pivot tapered bearings
Operation 40. Adjust service brake control
Attention
— For BELARUS-1021/1021.3 tractors equipped with optional multi-disk
brakes working in oil bath (wet brakes), the operation of adjusting the service brake control is
identical to the steps below for BELARUS-1021/1021.3 tractors with dry friction brakes.
Before adjusting the service brake control, install the tractor on an even horizontal surface.
The engine must be killed. Put brake shoes in front and behind the wheels precluding spontaneous
motion of the tractor.
Adjust the service brake control as follows:
- unscrew the locknuts (3) (Fig. 8.4.34) of the adjusting bolts (2);
- screw the bolts (2) into the adjusting forks or unscrew them to provide the right pedal full
travel of 105 to 115 mm under a force of 120 to 130 N and the stopping distance of 6.0 meters
max. at a speed of 20 km/hours and under a force of 600 N max. on the pedals interlocked with the
plate (1), as well as unsimultaneous start of wheel braking by no more than one meter (by tire
footprint). The left brake pedal travel must by 5-20 mm less than of the right brake pedal for
simultaneous action of the brakes in the interlocked position. Reduction in the brake pedal travel
by more than the indicated values is not allowable because it leads to premature wear of the linings
and overheating of the brakes;
- tighten up the locknuts (3).
