OK, so I got the special tool and bushing from US Diesel, cam screw cam out just fine (couple sharp raps with a pin punch). Pump is apart, and full of the governor flex ring crumbles. I can see the where the crumbs were plugging up the return check valve, and probably causing my engine shut down after 1 minute.
Got the one piece 29111 weight cage, rebuild seal kit, pilot bushing is badly scored inside, so I got a new one. I ordered a pilot tube mandrel and installation spacer, to press the new pilot tube in (Marco at US Diesel is most helpful).
I have a couple questions:
1. Is there an alternative to the A-12 #46739 epoxy for installing the pilot bushing? I see on the data sheet that this is a 2:3 ratio mix, with a high temperature rating of 82*C (179.6*F). I presume that is 2 parts catalyst to 3 parts resin, to extend working time? I have checked several places, out of stock. The quantities sold would be good for dozens of pilot bushings, I only need to do one. Does anyone know of an epoxy that I could purchase at the local auto parts, that would work for this application?
2. My return check valve seems to be the wrong thread size, or cross threaded by a previous owner. Is there more than one size of check valve for this pump? I found a number stamped into the mounting flange of the pump that reads "5 27 87". Is this a Stanadyne number, or was this pump maybe rebuilt on that date? What size is it supposed to be, 1/8" npt?
Thanks for any help you could give me.
