Hi Billy26F5 - and thanks for the info!
so for the oil pressure, if I get a new line, we should be ok? that would be great!
Temp gauge - it had been running a little bit, but I didn't really look at it after working for a little while - will have to try to remember to do that. lol
We popped the cap off the radiator that evening.. was still lukewarm at the time - not hot at all. the bottom of the radiator cap was wet, so I am going to guess that the level is ok, but if it should be seen, will top her up this morning. She never smells hot, even after running the back hoe for a bit at a high idle
She runs very well - the fuel system had been worked over very well.. new main pump, new fuel filter housing, new injector lines, and a new pad for the injector timing. Starts right up even after sitting for a couple of days.
Not working her real hard yet until we get oils changed, and filled to proper levels. Engine oil is pretty black, and the gearbox and rear end are slightly low.. but not knowing what is in there, we want to change it - looking a tiny bit milky in the rear end, too.. so moisture is getting in somewhere.. not a lot, but enough to notice.. the dipstick appears to be bent, so that could be where it is getting in.
(changing fluids is one of the first things we do with any new to us vehicle, LOL)
Her numbers are as follows
Serial - 1277576 - manual she came with says Jan 1954
Trans casing - P30U
Rear end - P9U
Front Axle - 7A4 < was told this may have been changed at some point as it is newer than the rest
