Injection pump for 2020

[Galen Houk]

I am getting my 2020 low profile utility injector pump rebuilt and they are having problems getting parts. The pump is JDB 431 AL and I believe it is the cam they need. Parts are not available for this pump anymore. There is a replacement pump but the lines are different and it gets pretty expensive to swap it out. Anyone here have a pump or parts?

Give these guys a call. I had a Bosch pump on a 2020 that everybody said couldn't be fixed because of a lack of new parts. I sent it to them and they sent the head off to Venezuela to have it rechromed. Took awhile to get it back but now I just tap the starter and it fires right up. Wasn't all that expensive either.

Is the place you brought that pump to and authorized Stanadyne dealer? I ask because it's hard to believe a cam-ring is no longer available for a DB, four-cylinder pump. Those pumps were used all over the place. Deere, Ford, Case, IH, Oliver, Allis Chalmers, Continental, etc. That being said, I cannot say I've tried to buy one lately. If you really get stuck, I've got a spare DB parts pump at my other place in NY. It's off a Case 207D engine. Most likely it uses the same cam-ring.
