I have an Allis B I have been trying to bring back to life ,got it going tonight but no oil pressure. Is there a way to prime oil pump without splitting tractor ???

Check the oil filter. If it is the wrong type or the little tube inside of it is missing you will not have any oil pressure. The correct filter is WIX 57011

You may be able to prime the pump by removing the gage, attaching a line to the gage port and forcing oil thru the system. I do this with a homemade air over oil tank. About 15 psi and 2-3 qts.of oil is enough to fill all of the oil galleries on an engine. That way you have full oil pressure and flow immediately on start up. I have heard a lot about Allis B engines losing oil pump prime, but it's never happened to mine in the 60 years I have used it. As Old says, check to be sure the tube is in place that goes up thru the center of the oil filter, that is a common problem. Worth a try.

Also, drop the oil pan and see if the suction tube has gotten loose, might be sucking air, if its loose.
