You are never going to believe it, the vp44 CAN be "rebuilt" in your shop/garage/lean-to!! Since my pump went out I have been feverishly searching for a cheap fix or the at least the cheapest rebuild I could possibly find……how does about $40.00 sound?!?! I have researched this in depth and found the common problems that cause vp44 failure, most of them are manufacturing process related (burrs left on metal components, pump case wearing through due to lack of lubrication, and parts seizing due to improper lubrication) Once the components have worn down they seize and of course the pump stops working, the less common failure is the electrical pack solders become weak and loose their proper connection, the connections could possibly be re-soldered but for the most part, when the electronics fail the pump has to be sent in as the electrical pack is calibrated to connect to the ECM on a calibration bench and unless you have a 100k to drop on a bench you may as well get a reman pump. As for the rest of the internal moving parts, it seemed to me you could just replace them….better yet, I found a guy that simply honed the parts and sanded them down with some fine grit sanding paper to relieve the clearance on these parts, he replaced the gaskets and lo and behold….his truck is now running!! I am in the process of ordering the gasket set he found and also am looking for the proper tool to remove the tamperproof bolts that hold the pump together, within the next couple weeks I will be attempting to rebuild my pump assuming the internal parts are seized and the electronics pack is not toast, once I have it apart it should be relatively obvious what the culprit is….. Here is a link to the site I found this information on, http://www.dieseltruckresource.com/dev/vp44-rebuilding-t111329.html in this thread you will find the part number as well as the contact information for ordering the gasket set to fix what is a ridiculously expensive problem for an otherwise excellent truck. This already worked out for at least one guy that had a bit of common sense and know how, I see no reason the same line of thought wouldn’t take care of many peoples vp44 headaches!! GAWD I HOPE THIS WORKS!!!!!!!
