Left-hand drive belts
Relieve tension on spring-loaded cylinder. To do this,
proceed as follows:
1. Determine the dimension (X).
2. Slacken off the lock nut (K).
3. Slacken off the spring guide tube (R) by the
previously determined distance (X). At the same
time tighten the nut (K) until the washer (S) is up
against the bracket (H).
The pin (B) should now be tension-free. Should
there be still a little tension on the pin, then a little
bit of adjustment may still be required at the spring
guide tube (R) and the nut (K).
4. Remove pin (B).
