How to replace the (Injection Pump Timing device) Stroke Curve on a bad vacuum pump.
Hello Folks,
I have a 95 E300D W124 with 152k miles and a very bad vacuum pump. Well pulled the pump and found a badly scared stroke curve. The instructions say I can't purchase an individual part that I have to install a complete injection adjusting device. Am I over my head here? Thanks for any help! David in Virginia |

Are you speaking of the timing device that runs off the timing chain?

Yes, the entire timing device. Not at all a cheap part and it's a major engine repair.

Yes, I'm talking about the ramp looking device powered by the timing
chain. Directions for the pump said you used to be able to purchase the part but now it is not available anymore. Said you need to purchase a complete injection adjusting device....what ever that is? Anyone have experience with this? |

What about replacing with a after market ele vacuum pump?
Folks have you every heard of anyone replacing the mech. vacuum pump
with after market one used by the auto racing circuit? Cost is around $329. and you get back some HP because it wouldn't be drawing on the engine. Heres a link of the pump I'm talking about. http://store.summitracing.com/egnsearch.asp?N=700+115+314448&D=314448 Good Idea? Bad Idea? |

Besides the fact the aftermarket pump costs more than what a Pierburg sells for the only real reason I can think of to go this way is to increase reliability, which, if you are using a new style pump, should be very reliable. Its the old pumps that were crap and have destroyed more than a few engines. If however you have a timing device (ramp) with a rough surface then installing an outboard pump is a way around a costly repair!

Just fix it properly with the correct parts.
