M35A2 Air system questions

[Lenny]

Does anyone know what is the typical air pressure in a fully charged M45A2 air tank? My air pressure gauge is messed up. Also what is the tank capacity? Thanks, Lenny

 

[Lenny]

Sorry, that should have read M35A2, (my failing eyesight)....

Should be about 120psi. No clue on tank size.

Hey Gimpyrodb sounds like my deuce 120 psi is good to go.Al.

 

[Lenny]

I'll have to check it with an external gauge. Thanks guys. Lenny

 

[gimpyrobb]

Just swap out your gauge. Just about any pressure gauge will work as long as it goes up to 130.

My M45 530C sits around 95 PSI, But I do have an auxiliary extra air tank fitted for capacity as I fitted air power steering. I was thinking of adjusting the air pressure up some when I get around to it.

 

[Lenny]

I didn't realize that was adjustable. How do you do that? Lenny

 

[gimpyrobb]

Thats a function of the air governor. I've never had to adjust one so I'll let someone else tell you how to do it.

TM 9-2320-361-20
8-29. AIR COMPRESSOR GOVERNOR MAINTENANCE (Contd)
c. Check and Adjustment
1. Start engine and buildup air pressure (TM 9-2320-361-10) until gage (4) reading is steady.
2. Check air pressure. Gage (4) should read 85-120 psi.
3. If air pressure gage (4) reading is correct, stop engine. End of task.
4. If air pressure gage (4) reading is too low:
a. Stop engine.
b. Remove cap (3), loosen jamnut (1), and turn screw (2) 1/4 turn clockwise.
c. Start engine and buildup air pressure (TM 9-2320-361-10). Check air pressure gage (4) reading.
If still low, check for air leaks and repeat step b. until air pressure is correct.
d. Stop engine, tighten jamnut (1) on screw (2), and install cap (3).
5. If air pressure gage (4) reading is too high:
a. Stop engine.
b. Remove cap (6) from air valve (5).
c. Turn air valve (5) left and bleed air until gage (4) reads below 100 psi.
d. Close air valve (5) and replace cap (6).
e. Remove cap (3), loosen jamnut ( 1), and turn screw (2) 1/4 turn counterclockwise.
f. Start engine and buildup air pressure. Check air pressure gage (4) reading. If still high, repeat
steps a. through e. until air pressure is correct.
g. Stop engine, tighten jamnut (1) on screw (2) and install cap (3).

Thanks Diesel Bob for the detailed explanation and the pictorial. It's simple enough. Lenny
