The adjustment of the brakes is shown in Fig. 5-5. The length of the control rod is adjusted so that
when the top of the brake pedal is subjected to a force of 13 N. the travel should be 20~40 mm.
It shall be assured also that the left and right brakes will work equally effectively.

5.5 Adjustment of Final Drive
For adjustment of preloading of the drive shaft bearings, see Fig. 5-6
(1) Place of piece of fuse wire of about 2mm diameter between the inner bearing cover and the bearing
No.7307. Place also a set of adjusting shims of a total thickness of about 1.5 mm. After mounting the
inner bearing cover, tighten the bolts with a torque of 40~50 N*m, to press the fuse into a flat plate.
(2) Dismount the bearing cover, take out the fuse plate and measure its thickness.
(3) Deduct the thickness of the fuse plate from the total thickness of the shims. This will form a set
of shims, the use of which will result in clearance or interference of less than 0.1 mm. Assemble the
shims and bearing cover and tighten the bolts with a torque of 40~50 N*m.
