'36 A has been having problems with the oil pressure. Gears look good, we tried to up the pressure not much of an improvement. Had 15-40 in it then changed it to straight 40 weight, it gets up just over medium & thick it all good till next time we start it & barely off low. Been cleaning dirt from inside the oil pump adjustment area, aswell as the lines. This weekend tried to start the old girl & would back fire out the exhaust. I took the valve cover off to find #2 exhaust valve was stuck. Got it freed up, thankfully didn't bend it. The pipe from the governor to the cover was Also plugged. Then I wanted to look in the governor to see how dirty it was, the bearings gone under the cover. Does anyone know the # for the bearing? I know they are a steering bearing I went through this on dads H. Sharps has the bearings, but doesn't say what years of A's they cover. Thanks,Kevin
