Help with identifying part on EDC injection pump - frans-c - 09-03-2017
I've noticed that my injection pump is weeping oil from the bronze (loose) cap at the of the injection pump (the one on the left, below the level of the shut-off valve).

On taking the cap apart from a spare pump I have (there does not appear to be any non-destructive method of removing the cap), I discovered an o-ring that was very hard and brittle; I assume my pump's o-ring is in the same condition, hence it leaking.
EPC doesn't list these parts (or any other internal components of the pump for that matter), but I did discover this photo on Peachparts. I want to replace the cap #123 and o-ring #124. However, I don't even know if the diagram is for an OM60x pump, although the thead was on the topic of an OM606. I'm not too concerned about the o-ring - that I can find anywhere; the cap is the most important. Alternatively, is there a method of removing the cap without destroying it?
