Oil filter failure

My new D-14 showed good oil pressure on the gauge and I guess it had plenty.

Anybody know what caused this or how to correct it I don't want to do this to many times, because filters aren't cheap.

Thanks for any help or opinions.

It wasn't brand new, but I don't know how old because I just got the tractor. It will peg the gauge when first started but comes down to the middle or slightly higher once it is warm.

The relief valve somewhere is stuck. There is one in  the oil pump and another at the front of the camshaft. When I bought my ol14 the oil gauge was rusty so I stuck one on from a car that read 80 psi. When it warmed up it wouldn't show any pressure so I put a washer behind the spring in the oil pump and I had great pressure but when the weather started getting cooler it would do the filters just like that. I took out the washer and got a gauge made for low pressure and it was fine. That was thirty years ago. I doubt anything was wrong with the filter. Wix is a high quality filter even though for some reason a few years ago they changed the design on the AC filter for awhile and it gave them a bad name. The one you have is the good one and I have never had a problem with them and I use mine to feed hay every other day in winter. Hope this helps.JP

I would screw it off and look for ice/water.

I have heard of that happing a few times. Faulty oil filter or a plugged up filter that had a bad relief valve.

I could be wrong, but I think the oil filter should have been of the cotton nature, and that is what is supposed to build up a little resistance and give you oil pressure. I know it sounds strange, but there was much discussion on the topic a few years ago and I believe it pertained to D14's and 17's. Maybe someone that knows more will chime in. Only thing that don't add up though, is that a faulty oil filter would cause a lack of oil pressure. Darrel

But, a D14 should be the "bypass" oil filtering system with the standpipe up thru the center ( like a WD45)......is the hole from the filter base to the block plugged  so oil can't get out???

Didn't you say you just bought it? I wouldn't do anything to it until I changed the oil and put on a new filter. If you don't know what it has in it then it could have maybe 50 weight racing oil or something in it to keep good pressure. This works good as long as you drain it before winter. I ran mine for about 25 years til I finally done a complete rebuild on it. I used to use the heavy racing oil and it would hold pretty good pressure all summer but you had to get it out before cold weather. I used to have a car I did the same thing with but like I say it had to come out for the winter.JP

I think I am going to swap change the oil out and try some 5w30 and see what that does for pressure.

New 5w30 oil had no effect. I stuck on a old filter to see what happened and it started to swell up so I shut her down. I guess I need to start looking into what is causing this. I noticed that there is oil in the base where the filter mounts and it drains away slowly, but it doesn't seem to be restricted. I see a small plate on the timing cover with four nuts retaining it, is this the plate that holds the pressure relief valve? it seems that it would be accessible without removing the radiator, can I just pop the plate off and check to see if there are any shims and remove the ball and spring to check them over or is it possible to loose pieces in to the engine this way?

The filter puts back pressure on the system. That is why the "new design" Wix came out with a few years ago didn't work right. I still don't why they did that. The oil pump has a relief in it and the cam does too but I can't think how it all works. I do know when I shimmed the valve in my oil pump it swelled the filters up.JP

Denis.  Check  for  correct  thickness plate end of cam.  Albert had  this  problem last  summer , i sent  correct  thickness plate  , problem solved.  No more  ruined  filters .     Tony

Can any body shed some light on how the D14 oil system works? I was under the impression that it is a bypass filtration system, but I only see one line coming out of the pump then it goes into the filter base. I don't see any other outlet for oil to come out of the pump?

OK, So I most certainly have a oil pressure issue. I installed a gauge that has numbers and I have well over 100 PSI at the oil filter base and the port on the side of the block. I am using 5w30 oil and the temperature outside is about 24. The relief valve is unseating because it is leaking oil out of its cover, so I don't really know where to turn from here.
