Brake arms (Ref. 19 and 12) are to be adjusted as described in part 6 of the Maintenance Section. If difficulty is experienced in obtaining adjustment check the location of the armature pins (Ref. 21) and the slot in the side of the arma-ture which engages the brake arm support  (Ref. 16). The pin should be located in the center of the armature with the center of the pin 5/8" be-low the top of the armature.  The top of the slot should be 15/16" below the top of the arma-ture.

Brake Springs - (See brake spring plan).

Brake springs are to be installed as shown on the brake spring plan.

Spring (Fig. 2) is secured to spring bracket (Fig. 3) by means of 1/4" X 2-1/2" stove bolts, the smooth section of the stove bolt providing free escapement for the downward motion of the spring.

Spring bracket (Fig. 3) is secured by the existing machine bolts that attach the end casting to the base casting.  In some instances it may be necessary to use longer machine bolts to provide a full-length thread for the nut.  The top portion of the base on the end casting is usually slightly sloped or may have rough pro-jections that will prevent the spring bracket from extending straight out from the end casting. In these instances it will be necessary to dress the bottom or the o-ring bracket with a file or to chip rough projections from the castings. The spring bracket must be parallel to the base cast-ing and stove bolt must extend straight up and parallel to the end casting.
