8.8 Replacing a shock absorber for S variants
Position of the item numbers, }8.12 [/57]
The shock absorbers have a limited lifespan, depending on the
load. For this reason, their function should be checked regularly.
The shock absorber is working correctly if the unit moves gently
to the end positions. When replacing it, observe the control
number "-446" at the end of the shock absorber designation.
These specially tested shock absorbers are only to be ordered
from SCHUNK. When replacing a damper, the complete additional
parts list for hydraulic dampening should be ordered.
Proceed as follows with the replacement:
1. Remove the compressed air lines.
2. Loosen the counter nut (124).
3. Remove the shock absorber (121) from the unit and remove
the sleeve (122). If the latter cannot be loosened from the
shock absorber, it may be helpful to use a small bar magnet
or turn the unit by hand.
NOTE
If the shock absorbers are installed vertically (horizontal axis of
rotation of the module), make sure that the sleeve (122) and the
ball (142) are secured against falling out.
Clean all parts thoroughly and check all parts for defects and
wear.
The unit is assembled in reverse order; finish by re-adjusting the
end positions Adjusting the end positions.
