Ive been digging all over the internet for the past day or so trying to find information about these pumps. I was able to source a seal kit for it locally in stock for 35 (factory Stanadyne parts) that I will be picking up in the morning. Through the magic of Google I was able to track down a factory service manual for the DB2 pump. Stanadyne Injection Pump Rebuild Instructions Pdf I KnowStanadyne Kit Number 24370 I found it in stock at two local places Perkins Diesel Service - Mesa, AZ - SWDiesel - Phoenix, AZ - You can also find it on eBay for 26 and up link Factory Service Manual: click on thumbnail below View attachment IP Shop Manual.pdf I know most of you frown upon someone doing any IP work at home.but Im stubborn and have to try it myself before I can justify farming out the work or buying a rebuilt unit. Im sure Im not the only stubborn one around and someone else might be able to find this information useful. Stanadyne Injection Pump Rebuild Instructions Update This ThreadIll update this thread tomorrow with how things are going with pictures and everything. Ill provide tips and tricks that I find make things a little easier along the way for me too. Just make sure you put it back together right or it will runaway. I found it is an incomplete manual that describes an old version of the DB2 IP, and is not complete enough to dismantle a more recent model of the DB2. Youll need to take off the intake manifold to pull the shaft completely out, remove the o rings install new ones. I still have not gotten the hydraulic head or drive shafts out, but that is all that is left. They were glued on with high melting point esters (fat), so it required heatdiesel fuelultrasonic cleanerpulling hardwigglingtwisting to get them off. There were 2 broken drive shafts, so I hope to reassemble and reseal 2 of them today. I suspect that by the time one of these IPs fail, its hydraulic head is worn out, and will not make pop pressure, so I will not be doing it again. The IP on my 1986 M1031 has the low speed governor retainer issue. All my plow trucks have the same DCP Memphis pumps and the Easter Find M1008 has one also. I ran contaminated fuel thru a few and had less then favorable results but in the end they corrected themselves with good fuel. ![]() Free Fuel. Why NOT. Then winter came. Silicon seals tend to swell if alcohol is in the blend over 3, and the even swell badly with xylene above 5. The real problem becomes apparent after running gasoline-based waste oil blends, then followed by straight diesel fuel with xylene in it. However, if the straight diesel fuel with xylene in it is never more than 50 of the fuel blend, then I had no problems with the DB-2 IP. So, tell the rebuilders to stop using silicon seals when they rebuild the Stanadyne DB-2 IP.
