Also, the guy at Napa told me he could match a gauge and sender up if he knew the thread size for sender? Do you know the thread size

Who is lavoy?

Will any aftermarket gauge work with these sending units or do I have to get a different sender as well.

Hey guys i am having trouble finding the oil pressure sensor/sending unit part number for a 450b dozer. do any of you know it?

The oil pressure gauge is moving but the moment I turn the key on even before I start the gauge goes up some . This can’t be right.

Short of removing the tank what’s best way to clean it out ?

I’m way before that serial no. So doubt I have a in-line screen. How do I check the vent

Does a 450b have any in line fuel filters or strainers other than the 2 that are on the side of the motor. Mine is starving for fuel getting to the lift pump

My oil pressure gauge is not working. What is best way to test it. Is it just one wire where I can ground to block to see if sender or gauge?

I do not have turbo. I just got this dozer and starting to go through it. so the picture helped it appears i need to access it from behind the fuel filter.

Thank you sir! Yes I do not have a turbo but i was thinking it was behind the fuel filter. I couldn't find it in my technical manual what page is it on.

Is it behind the fuel filter? I still can’t seem to find it

I believe I have a turbo as I got the breather coming out of the hood. So where is relation to the turbo is the oil sender?

Hey guys does a 450b have a hydraulic filter in the tank and where is the oil pressure sending unit?
