Hi
it's a long time since i have been posting on this forum, however my 1950 TEA has had some oil pressure issues for some time now.
Im running straight sae 40w, the pressure gauge is an
aftermarket one with uncertain accuracy
I followed John UK's advice from a post back in 2004, that i copied in below.
I turned the relief valve
screw in two turns, that resulted in 100 psi at full
throttle, backed out half a turn, and got 80 psi at
full throttle on half warmed engine.
After 18 km driving in 4th gear and full throttle the
engine was thuroughly warm, and now I have 60 psi at
half, to full throttle, and 0 psi at idle. At 5-600 rpm
i have around 10 psi.
So what do you guys think? Is it time for an engine
rebuild soon?
Regards Jone

The oil pressure on a good engine should be 40 - 60 psi at anything over half throttle. The oil should be 20W/50 unless you are in a very cold climate then you should change to a slightly lower grade. Have you changed the oil filter, that can affect the oil pressure reading and there is an adjustment on the top side of the oil filter, try screwing in in a couple of turns to see if it puts the pressure up, if that doesnt work Have a look at the filter in the oil pan (the oval plate on the right side of the oil pan)make sure its clean. If that fails you could drop the oil pan and check the bearings, if they are down to the copper backing they need replacing if the C/Shaft is worn it needs a regrind. If it just needs bearings I would change the oil pump Rotor too, they are available from Sparex Part number S61996, it should also be available from this site too (top left of this page and click on H.Ferguson)Any good tractor dealer should be able to get this for you. You can get bearings too and gaskets. If you have any problems post again.
