Vaccum actuator for diff and tranny

[Denis]

  I routed air lines for my 100Q for manual lock , center and rear (016 tranny) and i noticed an air leak.


  I pump vacuum with my mouth to each vac side of the lock actuator on the rear diff. I noticed one side is ok and the other leak.
  I did the same thing on the others i have in stock, all did the same !!!

  I tought each side of the lock act have seal diaphragm !!! suppose to be without leak on both side ?

  If not, all my actuator are bad :-(.
