Help.
Vacuum pump replaced last week. Started holiday, half way to Scotland and lost power assist for brakes. New vacuum pump has sheered all the bolts holding the cover. On line found part numbers 075145100 and 075145101a. I don't know which the broken one is! Any idea which I need 1989 LT31 Florida with the 2.4 TD engine 102 HP, 75 KW Model DV Thanks for any ideas

Just a thought - did you replace with exactly the same part number pump? There is a variation in the length of the diaphragm operating rod (the rod inside the spring). The difference in length means that the pin that runs the pump from the camshaft can be one of two sizes. My understanding is that if you fit pump with a 'long' operating arm, to an engine that has a 'long' pin - it'll smash the pump up. The pin just slides out of the head so can easily be changed. Maybe worth checking before you put another pump on - I'm always a bit wary of replacing parts when I have an unexpected failure. |

Back in the slow lane, yeah!

Unfortunately no VW parts are available so the mechanic used what the supplier sent. Can't check the original now as it is a couple hundred miles away and probably disposed of already.
Does anyone else have an idea of how I can tell if the samples arriving in the morning are the right one? Thanks Roger

Problem Solved
The Brickwerks service department did not have the correct part available but they kindly sent me a Pierburg service bulletin which clearly states the problem and has a photo of the correct pump. Evidently the part number cross checkers don't always note the change VW made in 1994. Note: this also applies to some T4 as well. Edited by Roger - 12 Jun 17 at 17:27 |

Reposting Piersburg Service bulletin as image in previous post may soon disappear due to photobucket changing their T&Cs.
