M35A3 Wheel to hub O rings

[R Racing]

I did a search and didn't turn up any part numbers or sizes. I'm doing a tire changeout this week and would love to have them in hand. Any help would be greatl appreciated !!

I got some from Erics military surplus, it was almost 2 years ago though.

Wheel to hub O-rings? Not sure what you mean. Are you talking about something for the ctis? The air goes through one of the wheel studs. There is no O-ring between the wheel and hub.

The O-rings you are after are inside of the hub assy. There are 4 per hub. Don't have a p/n for you but call one of the surplus guys as they are more likely to have them.

.... OP said "tire changeout".... I think he meant the O-ring between wheel halves...?

If so, the part# is 12363606, NSN # 5331013147598

I have a tire with my ctis that loses air over night .after talking to and reading a few posts I was under the impression there was a o ring that goes bad at the wheels that causes this. Since Im changing out the tires I thought it be a great time to change the o rings and fix the 1 leak I have at the same time. Any help is appricated.

RR, do you have the TM 9-2320-386-24P? Figs. 117 & 118 show all O-rings and seals, hub to spindle. Front and rears are different.

Sounds to me like this is what you want. If you are putting new tires on, I would put new O-rings on all the rims.

Thank You ! Now on to fix the Air assist steering , LOL

Don't forget to replace the rubber grommets under the valve stem! Also, they need to be torqued to 45-60 Lb-ft. I find that they are more likely to leak than the wheel o-rings, probably because when touched, they disturb the seal.

Got everything ordered ! Thanks guys ! Now need to find a Air assist cylinder. 2 bottles of air tool oil and its blowing air thru the cylinder when you turn left like wide open 90 psi

The bad news is that many times water makes its way down to the o-ring sealing surfaces and rusts the sealing surfaces (especially with salt water environments). Takes some sanding,filling and painting to make a good sealing surface again.
