Hey guys, I am new to this forum and own a 1985 Allis Chalmers 653. Unfortunately, I believe the shaft in the injection pump has broken. Is there a rebuild kit that anyone is aware of for this with the seals? I plan to take it out this weekend and actually look but trying to get ahead. I have seen a lot of people mention it is based off of an HD4. I know some places can rebuild them but want to be able to do it myself and learn along the way. Any insight would be extremely helpful, thank you in advance.

Roosa-Master pump? Easy pump to rebuild but you can't calibrate it correctly and that is best left to a fuel shop with the needed equipment. Lot of wear parts to be addressed.

Try posting this in farm equipment section and maybe injectorpumpEd will comment. He has a pump rebuild shop and would give sound advice. Not sure if he looks through construction area.
