Vacuum pump diaphragm bolt toque etc.
Hello,
I don't have a manual for the girlfriend's '78 240D. We pulled the vacuum pump, cleaned it, replaced the ball bearing with Nachi bearings from Japan. I put new diaphragm in with the convex shape pointing up or forward towards the radiator. I put blue Locktight on the diaphragm bolt and tightened it. Now there is no movement in the diaphragm when I compress the spring. Is the bolt supposed to not be tightened all the way down? What is the torque supposed to be? I won't be the hero until we get it back on the car. Thanks, from the girlfriend and me... |
