Control Valve Adjustment (1968-69)

  1. Adjustment should be performed with a full fuel tank (or equivalent load). Raise vehicle on hoist and support rear axle. Load rear of vehicle to achieve a riding height measurement of 6.44", as measured from axle to frame, at axle rebound bumper.
  2. Remove shock absorber line at control valve. Connect a suitable fill valve (part of tool T68N-5A681-B) to shock absorber line. Inflate shock absorber to 8-15 psi, and jounce vehicle to equalize suspension.
  3. Connect test gauge to shock absorber adapter on control valve and attach 80-110 psi air source. Loosen overtravel lever adjusting nut and hold overtravel body down in exhaust position until air escapes from exhaust valve port. Slowly move overtravel body and tighten nut at point of minimum air bleed. With nut tightened, a slight continuous air bleed should be noticeable.
