Can anyone tell me where the oil pressure sensor is located on the engine of a L3301 or L3901 ? I am curious and can't find it.
Thank you, Pete;)

Sorry to tell you, but MD is right.
The picture of what MD put up is the oil pressure sensor! ;)

The coolant sensor is up above this sensor about 8", it also does not have a single light blue wire with a fork connector. ;)

You can go here and download the WSM for that tractor:

No Kidding ???
I unhooked the wire off the one you have listed as the "oil sender". The one with a fork connector and a single wire to it. The one by the radiator return hose.
Anyway....when I did...and turned on the key (with a warmed up engine) The coolant gauge just sat there....no sweep as normal.
No lights on for oil pressure warning.
I may look at it all again, but I doubt it...because this DPF baby is getting traded in for a L2501 tomorrow. It is a great working tractor, but I am tired of not being able to idle it without worrying about plugging up the filter, etc...and dreading the time to regen.Also the computer running things.
Should not have bought it but I simply did not know about this stuff and too dumb to research the tractor.

The sending unit goes to ground when there isn't any pressure, so taking the wire off doesn't do anything. If you ground it the oil light will come on.

I have 280 hours on my L3901DT and haven't had to do anything special when the tractor is regen'ing. You just have to keep the RPM's up until it is done, you just keep on working.
