In Kent's manual '61x Automatic Transmission Tuning', on page 17, there is a description of how to adjust the ALDA.
You show a wrench around the locking nut. On W126's at least, the locking nut is not exposed. I cut the plastic cap off, but there is a metal "collar" or cylinder surrounding the screw & nut. This cylinder appears integrated to the top part of the aneroid capsule body itself, with no obvious way to remove it. There is no mention of this in the instruction.
How do W126/OM617 owners get to the locking nut with this collar so close around it? I think this may be the cause of some reports of people breaking theirs (trying to adjust the screw without loosening the lock nut).
Also:
- must the car be off for the adjustment?
- which way is "loosen" on the locking nut?
- how tight do you re-tighten it?
(I think this info should be added the print instructions too, once answered here.)
Thanks.
