I've got an interesting issue and any suggestions or thoughts would be great. I have a 2003 Kubota L35 TLB with 1180 hrs on it.
A few weeks ago I was doing some levee work on our property and I had my oil pressure light pop on and it comes on and stays on once you get to 1900 rpms and higher. Weird. Here is what I have done.
1. - I swapped out my oil pressure sender switch Part # 1A024-39010 === still getting the light
2. - Changed my oil and oil filter. I had been using 15w 40 and a Kubota brand oil filter. The oil and filter only had 20 hours on it but I changed everything anyway. Same oil and Kubota brand filter === still getting the light
3. - I bought a brass t fitting, adapter, copper tubing, and oil pressure gauge. I wanted to see exactly what my oil pressure was doing. I got everything installed and started it up to get a reading on what is going on.

My pressures are as follows:
1000 rpm - 57psi
1500 rpm - 60psi
1800 rpm - 65psi
1900 rpm - 67psi
2000 rpm - 68psi
2200 rpm - 70psi
2500 rpm - 75psi
The light is still coming on at 1900 rpms. As far as I can tell from these pressures, everything is looking good. Here are a couple questions I have.
1 - Does anyone see any issue with those pressure numbers?
2 - Any other ideas why the light could be popping on?
The tractor is running great. I don't see any indications of issues. I recently changed the glow plug relay and controller but this oil pressure light came on before I swapped those out so I don't think there is any relation. Thanks for your thoughts on this...
