2004 Mahindra 4110
Greetings. Has anyone changed the oil pressure relief valve on a daedong 4a200 engine. I recently tore my engine down and replaced the oil pump as well as Camshaft gear. Both were destroyed. I still don't have enough oil pressure to make the oil pressure light go out. Also does anyone know what oil pressure is supposed to be? I think I have 4 or 5 psi? I may pull off the oil filter housing to see if i can find the relief valve. The parts diagram isn't clear.

Found the daedong engine shop manual online. 7psi is the minimum pressure to turn off the light. Also Found the location of the relief valve. Under a cover next to oil filter. I am going to try to get that cover off without removing the gear cover again

I have to pull the gearcase cover again. I will update this thread after that is done and I know more

Was that manual a freeby or a purchase? Would you share the link?
Thanks

Getting close to having it back together a second time. I installed the new oil bypass spring . I don't think that was it. Nearly identical in compression force to old one

Tractor is back in service. It is clearly moving oil and sounds ok, but oil light stays on. Other than a full engine rebuild i can't think of anything else to try. Already put a few hours on it.
