I have a 1959 D14. the oil filters at NAPA (wix) bring the oil pressure up on the guage. I noticed this the last time I changed oil and I have changed recently and the guage reads high. I do not remember what was on the tractor prior to using the NAPA filter, but the pressure was in the middle of the normal range and now it is in the high side. Possibly the media is denser creating more resistance ??? Anyone seen this before ? My other problem is hard starting. When cranked over fast, the engine does not want to start. Bumping the starter a few times seems to find a sweet spot and the engine fires. It runs very well, idles good, power is good but it is sometimes difficult to find the spot and annoying if nothing else. i would appreciate any insight you may offer into these two issues.

Thanks

Mike

My guess is you have a 6V tractor and it's been converted to 12V. My Oliver 60 used to do the same exact thing. 6V tractor with 12V battery. Cranked really well, but would not fire. Turned out the battery had a bad cell so the cranking voltage was dropping below 9V while cranking, too low for a 12V ignition system. It would fire off every time when the starter button was released, or the hand crank was used. A new battery fixed that issue.

There was an issue with Wix filters at one time. They tried to go to a pleated paper filter that no doubt did a better job cleaning the oil, but did not have the proper density and caused very low oil pressure. Could be the situation you are thinking of. One filter being senser than another.

If it has the 7011 Napa (57011 Wix) filter then it has the right filter. I sell Wix filters and use them on my D14 with no problem. Did you put in different weight of oil.JP

You will see different oil pressure after changing filters even when you use the same filter. I use Fram P-159 and Napa 7011 {Wix Filter} and I see different pressures all the time.
You can put on a brand new filter and check the pressure and then put on another new filter {Same brand and number} and get a different reading. They are not made with the best quality but they want to get top dollar prices for them. Napa is up around $17.00 for a $6.00 filter.

Don't worry too much about oil pressure with that engine.
Even if it drops to 5 lbs it will probably be running long after you are gone.

An old AC guy around here told me once "as long as it has good pressure when you first start it,don't worry about it."JP

I have some B's and C's that don't even have good pressure when I start them and I still don't worry about it.
Some have been that way for over ten years and probably will be that way for the next 20 years.

Just try to kill these engines.

Thanks for the replies. The dead cell in the battery makes a lot of sense. It has been converted. The battery is real old. It seems to start just after I have let off of the key and likely the distributor sees 12volts at that moment. I will try a diffrent battery. The battery has been in it since I have owned the tractor ( nearly 15 yrs) You can always hope something lasts forever ! I have the right NAPA filter, just was concerned about the higher pressure, but it sounds like it should not be a problem. I will post the outcome of a different battery.

Thanks

Mike

If you have the dropping resistor on the coil , check the wires as there should be a wire that bypasses the resistor when starting . On older GM cars this wire ran from 2nd terminal on starter solonoid directly to coil. On later cars they use a resistance wire from switch to feed the coil but had a bypass wire in system to deliver full voltage to coil when cranking.

Ford style 4 wire solenoid has the bypass marked I.
When using a ballast resistor run the I wire on the 4 wire solenoid directly to the coil bypassing the resistor.

Might try checking your points gap, and setting them a little wider. Turn the key on and use a meter or test light and check for 12v at the coil and points. If it's a distributor ignition, it shouldn't start or run with a bad cell. I don't think you would get any voltage from a battery with a bad cell anyway.
