1980 5040 has a leak (steady drip) on injection pump

Jim Flowers · May 3, 2014

I have a 1980 Allis Chalmers 5040 that runs good, doesn't smoke or overheat and really does not have but one issue and that is there is a steady drip on the injection pump about in the middle where the name tag is and right above what appears to be is a nut with a knot (acorn nut) or top of a rupture disc. Is there an oring that may be replaced and can I fix the leak without removing the pump ? Is there any prints and/or trouble shooting guide for the injection pump? Thanks in advance for any responses and help.

Might try tightening the nut. Worked on my uncles.
