Adjustment Procedures

Series 80, 82, 86, 8040 & 8240

1. Remove the shock absorber from the vehicle and hold it vertically with the lower eye or pin attachment in a vice. Use clamp plates to prevent damage.
2. Fully compress the shock absorber, at the same time turning the dust cap or piston rod slowly to the left (anti-clockwise), until it is felt that the cams of the adjusting nut engage in the recesses of the foot valve assembly (fig. 1).
   NOTE - Some shock absorbers include a bump rubber concealed under the dust cover and this must be removed prior to adjusting. Don't forget to re-install.

   

3. The damper may have already been adjusted. Therefore, check whether the shock absorber is in the unadjusted position by keeping it compressed and gently turning further to the left while counting the half turns until a stop is felt. Then stop turning and do not use force.
4. Keeping the shock absorber compressed, make 1 full turn (360') to the right (clockwise). In case of prior adjustment, add half a turn to the number of half turns previously found. The total range is about 4 to 5 half turns (fig.2).
5. Extend the shock absorber vertically for at least 1 cm without turning in order to disengage the adjusting mechanism. The dust cap or piston rod may now be turned freely.
