BELT GUIDE POSITIONING

5.2.9Brake Link Adjustment.

Check to make sure brake is adjusted properly.

a)Disengage brake lever (lever down).

b)Measure the length of the spring. Measurement should be 2.75” (7 cm) (See Figure 16).

c)If adjustment is necessary, adjust the nyloc nut at the bottom of the spring to achieve 2 3/4” (7 cm).

d)Engage the brake lever (lever up).

e)The space between the brake spring bracket and the nyloc nut under the spring should measure 3/16” to 1/4” (4.8 – 6.4 mm).

f)If adjustment is necessary, loosen jam nut above the trunion roller. Adjust the nyloc nut under the trunion roller until 3/16” to 1/4” (4.8 – 6.4 mm) exists between the spring retainer bracket and the adjacent nyloc nut. Tighten the jam nut above the trunion roller.

g)If a 3/16” to 1/4” (4.8 – 6.4 mm) gap can no longer be achieved because there is no clearance between nyloc nut below the spring and the jam nut above the trunion or there are no threads left on the bottom nyloc nut, the length of the brake rod can be adjusted. Remove a pin from a yoke at either end of the brake rod and lengthen (or shorten) the brake rod until 3/16” to 1/4” (4.8 – 6.4 cm) gap can be achieved by following steps e) and f).
