formariz 12,045 #1 Posted January 2, 2020 A while back I was having trouble with my oil pressure light in my 520 and decided instead to introduce a gauge rather than rely on a light. Did also a transmission temperature gauge. New oil sensor for gauge is substantially larger than original and would not line up with hole in engine so it required some additional plumbing using brass fittings. When weather got cold and metal shrank it developed an oil leak. So back into I have to go. Easy job but time consuming is removing and reinstalling engine shroud. So I decided to bring sensor totally out of that area. Used a stainless braided racing line made for that application. Effectively also reduced joints in the system, and now working on sensor or its electrical parts is within a second . 3 2 1 Share this post Link to post Share on other sites

N875ED 98 #3 Posted January 6, 2020 RedSquare Pro: I wanted to let you know that clamping the oil pressure sensor directly to the engine shroud will probably reduce the life of the sensor. These devices use a mechanical resistance "wiper arm" connected to the pressure sensing tube, and the constant vibration tends to wear out the electrical resistor on the arm, rendering it inoperable. Since you already have the hose, suggest you just mount the sensor to the chassis somewhere within reach to drastically reduce the vibrations it experiences. 1 Share this post Link to post Share on other sites

However at this point tractor has blower and cab mounted which restricts opening hood greatly making it difficult to install sensor in another area so I decided just to mount it there for now. It will be relocated in spring once blower and cab come off.. Share this post Link to post Share on other sites
Greentored 3,220 #5 Posted January 7, 2020 I dig it! Was thinking about doing the same on my 520H, but with mechanical/analog gauge style. Would like to do the same with a head temp gauge. What kind of oil pressure do you see on these engines? Share this post Link to post Share on other sites

I am not aware of anyone else having a oil pressure gauge in theirs for reference, but on mine it idles at 16 PSI and at full throttle will go up to 50PSI.
