5.2.9 Brake 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 12).
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).
5.2.10 Adjust Throttle Lever Tension.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Tension in throttle lever can be adjusted by adjusting the tightness of the
lever pivot bolt, which is located under the console (See Figure 13).
