2420 injection pump ?

[bobfor]

All right guys got her running ,a new pump was the ticket just have to rig up the throttle and fuel cutoff tomorrow as the rain has put a hamper on things in N FL. Thanks again for all your help,Bob Also wanted to ask on the timing,when I removed the pump there where keys on the pump shaft and then the gear so I don't see how it could of went back on incorrect (so that the timing would be off)? Also this is the 2 cylinder TY290 so is that the reason? thanks again Bob

Under normal circumstances the tang should slide easily out of the slot, and the drive gear would remain inside the housing. If you need a gear puller, the tang has rotated enough in the slot to have jammed. And operating with the tang no longer aligned correctly in the slot necessarily changes fuel delivery timing proportionate to the number of degrees it's jammed off center.

Greg I definitely understand what you are saying,but with the woodruff keys,slots for the gears it cant move unless something got jammed and then it would be a mess. And like I mentioned with those it can only go back on one way?

Ok, my bad. You were talking injection pump, I was thinking hydraulic pump. Sorry for any confusion.
