Gap measurement in brake В1



1. Insert a radial epiploon (39) into the piston of a brake of B1 (37).
2. Insert a finger with laying and a sealing ring into the piston of brake В1. The sealing edge should be located outside.
3. Fix a stripper (026) and tighten it on a transmission, establish the measuring device (031).
4. Insert the piston of brake В1 (37) with one press spring.
5. Tighten on a spindle the device (026). Be convinced that a finger of the piston of brake В1 (37) which is established on a brake tape, and a radial epiploon (39) are not damaged.
6. Insert a lock ring (41), weaken and remove the device (026).

Measurement and gap adjustment


1. Tighten the measuring device (031) by hand to resistance.
2. Having put on a key a bolt, screw the measuring device (031) for a bolt, counting up number of turns until the moment in 1 N.Rezba of the measuring device will be defined has a step of 1 mm so one turn is equal to a gap in 1 mm.
3. Weaken the device (026) and remove the brake piston if it is necessary.
4. Adjust a gap, having inserted or having removed laying (136) on a finger (38). Thickness of laying: 0.5, 1.0 and 1.5 mm.
5. Establish a cover (40) pistons of a brake and the second press spring (35) into place in the measuring device, insert a lock ring and unscrew the device (026).
