I have an oil leak coming out of the casing of my vacuum pump. I do not believe the case should be full of oil, so I think it's just leaking past the shaft o-ring or packing or whatever it uses between the oil supply and where it is coming out of. Has anybody ever torn one of these things apart? And where could I get a rebuild kit? I don't know the model # for the pump off hand, but it's in a 98 12V. I will probably take it to a shop, but I would like to have the parts so I don't get taken on their price. And as far as shops, are Cummins shops as bad as Dodge stealerships when it comes to pricing?

 

http:\\www.fixinrams.com has a kit for around $60. I fixed mine in about an hour and a half.

 

Sweet, I'll give em a call in the morning. The pump looks simpler than I thought. Maybe I'll just do it myself. Nothing wrong with saving money and getting dirty.
