Oil Cooled Steering Clutch and Brake
(Power Shift Transmission)
Use the following procedure to adjust the brakes on machines with power shift transmissions when the brake pedal(s) touch the fire wall or earlier at the operator's option. 1. Tighten the brake adjusting nut (1) to a torque of 43 N m (34 lb ft).2. Check the brake linkage for excessive free pedal travel. Free pedal travel should not be more than 13 mm (1/2 inch).3. If excessive free pedal travel is found, check for worn, damaged and/or incorrect linkage components.A small amount of free travel can be adjusted as follows1. Remove pin (2) which fastens rod (4) to lever (3).2. Pull lever (3) back as far as possible and hold it there. Then, while pulling rod (4) back, adjust the length of rod (4) so it will freely connect to lever (3) with pin (2).If it is not possible to adjust the pedal travel to specifications, with the brake adjusting nut torqued to the above specifications, check all internal brake components for wear and/or damage.After free pedal travel has been adjusted to a minimum with the brake adjusting nut torqued to the specification given, loosen nut (1) 21/2 turns (15 clicks).The left and right brake pedal should have approximately equal free pedal travel. If they do not, tighten the adjusting nut (1) on the side with the most free pedal travel until free pedal travel is approximately equal on both brake pedals. One click of the adjusting nut (1) equals approximately 5 mm (1/4 inch) of pedal travel.Tracks
If tracks are too tight or loose, wear of components is accelerated. If they appear too tight or too loose, adjust the track. Follow the procedures in the "Maintenance Section" for adjustment.
