Everything was going great. Just finished replacing belt tensioner lever and pulley, belt, water pump, fan clutch - with some spot cleaning thrown in (oh the filth). "Oh look that vacuum line is split, I'll just snip it and push it back on" ... the *&^%$ nipple on the brake booster line
non-return valve broke. Why oh why did the Mercedes engineers invent their on vocabulary, why not call it a check valve. Hmmm, I'm digressing
Anyway I am having a hard time coming up with a part number for the line from the vacuum pump to the brake booster with a check valve in the middle that also T's off to the key operated engine stop valve. The closest I can find on EPC is 140 430 07 29 but the EPC description is INTAKE MANIFOLD TO BRAKE BOOSTER ASSEMBLY which just doesn't sound right. Mine looks suspiciously like:
If someone knows the p/n for a W140 1992 300SD, vin WDBGB34E0NA039946, I would appreciate it.
Normally I can find what I need. I remember looking for this when I first got the car because the check valve had that white-ish color that some plastics get when they have been sitting around in the heat too long, but I couldn't find it and gave up because it
was working.
In the interim, I'll plug where the nipple broke off and T in somewhere else for the stop valve or just open the hood and push the lever.
That was an awfully long post for a p/n request - maybe it was the beer after coming in from working in the heat/sun.
thnx,
Bill
