Oliver 1800 Engine Oil Pump

Anonymous-0 · Jan 7, 2013

I have an engine oil pump from an Oliver 1800 gas, with regards to the oil pressure relief valve. There are two drillings through the casting for a carter pin to secure the plug that holds the spring against the relief valve. Is this for two different pressure settings?

Thanks

Imposter, I don't know anything specific about the 1800 oil pump, but I have the oil pump out of my 1650 diesel. I am going to see if there is a way to connect air pressure (42 psi for the 1650) to the pump body, then adjust the relief screw until it just dumps pressure. The cotter pin holds the screw adjustment so it can't back off. Jack
