s/b chevy oil pump.....how do i.....

clanu up around the relief valve ?? I'm a ford guy, so excuse my ignorance of the belly button oil pump Always prep my oil pumps (deburr, smooth the edges, chamfer the oil passages, etc. On the pump i have in my possesion, (sb chevy) the relief plunger looks like it is held in with some sort of a press fit plug. Question here is...is this removable, to check the relief plunger travel, cleanup of the passage after it is deburred, polished etc? And if it is, is there a preferred method of retaining the new plug, (stake in place, jb weld ect )

If you remove the bolts holding the cover plate to the main body. Look at the mating surface on the cover. Where the spring housing is, there will be a roll/solid pin. drive this pin out, towards the machined side and the relief spring/valve assembly will slide out of the bore. DO NOT mess with the valve itself. But you can chamfer the housing. Or even make anti-cavitation slots. Re-install valve, make sure it slides with no bind. Install spring. Us old Hotrodders always want to install a couple of washers for a bit more pressure!!! Not really necessary tho. Better than stretching the spring, then finding out ""OH my GAWD!! 150 lbs. OIL pressure!!"

Have fun! BOB
