Adjusting lever (ratchet) 120-3501136, Kharkiv region.

Adjusting lever 120-3501136 assembly, ratchet, driving tractor axle of wheeled tractors manufactured by X T Z, T-151, T-156, T-17221, T-17021, T-157, T-150-05-09-25. In the body of the lever there is a worm gearwheel, installed on the shaft of the expansion fist, and a worm with an axle pressed into it. The axis of the worm is stopped by a ball that enters the holes on the axes of the worm and is pressed by a spring that rests against the stop bolt. When turning the square end of the axis, the worm turns the gear wheel, and together with it, the expansion fist - as a result, the pads expand, and the gap between the drum and the pads decreases. This gap is adjusted manually. The need for regulation is established by the output of the rod from the brake chamber; it should not exceed 40 mm. In the regulated state, the gap should be 0.4 mm at the expansion fist, 0.2 mm at the axles of the pads. The gap is checked with the help of a feeler gauge through the windows in the brake shield, located at a distance of 20-30 mm from the ends of the pads. The windows are closed with rubber plugs.
