180 injection pump thrust button

Good morning. We are finally getting our 180 put back together. After three years of being spread out all over the farm we are down to the last few items. Unfortunately the front cover for the injection pump drive gear got lost. Thanks to ebay another is on the way. However the thrust button is no longer available. I have a new spring coming from Agco, but no button.Any ideas where to get one or a set of measurements to make one. Were they used on anything else? Thanks.

You need to provide more info as to which type people need to look for. The pump bolts to a separate adapter and that adapter bolts to front plate, pump uses the long 16444 shaft, takes a different button than the later short shaft 10213 where pump bolts right to front plate. Neither version is available from Stanadyne though. You'll need to get the AC numbers off Agco Parts Books web site, and hunt salvage yards. There's bound to be lots laying around. I have very little of that type of thing here as most pumps come without the shaft. Good luck in the hunt!
