Prelube on all deuces and what to look for?

[wsucougarx]

I did an inspection of several deuces yesterday. We were not allowed to start the trucks up but I did do a check on the prelubers. I have a question, do all M35A2's have prelubers? Is the oil pressure suppose to increase when you turn the switch (sorry I am new to this) and the buzzer comes on? I noticed a couple trucks had the increase in oil pressure and others did not. Is the preluber dependant on the battery condition? The trucks that I checked said that they do not need a jump and the volts looked good. If the oil pressure did not go up during the "prelube" what needs to be done to remedy this or can this just be left alone and not have prelube?

Thanks

No worries but no prelube. Think you were looking at the air pressure gage.

No I was watching oil pressure. It was my understanding that the OP was suppose to increase during the prelube process. Please advise

Not to be rude, but unless you have been reading about another model MV you are confused. No prelube system exists on a deuce, its part of the design shortfall. You just lack oil press untill the engine has run for 15-25 seconds. People on here have added prelube systems to give thier engine a hand in this dept. but i'm sure the army hasn't.
Good luck in your search for a truck.


Oh one more thing, if your seeing pressure with the engine off then the gage is wrong, its just not gonna happen on a stock deuce.

The deuce does not have a prelube system (unless somebody added an aftermarket one). The oil pressure needle may move a bit when power is applied, but pressure won't come up until the engine is turning. From a cold start, it might take 10 seconds or more for the oil pressure to rise after the engine is started.

Turning on the master switch on the dash energizes the in-tank fuel supply pump, but it doesn't do anything that will affect the oil or air pressures.
