Air Pack Lubrication

I received a 8 page book of sorts titled TECH TIPS by bob kettler with my truck and in it there is a tip regarding lubrication of the air-pak. It states that you should lubricate the air-pak every 6 months with some OHT oil. Does any one know what this oil is and where to get it as I have never heard of it? Has any one here done this before?

What you want to use is tool oil, same stuff that you use to lubricate you air tools...

According to FM 9-207 it is:
Hydraulic Fluid, Petroleum Base for Preservation and Operation (OHT) MIL-H-6083, NSN9150-00-935-9807 for 1 qt-can.

In other words "oil, hydraulic, tool" in the old parlance...

where do you put the oil?

On the back of the air pack there is a small plug to unscrew and squirt some oil inside.

Thanks for the info.

every six months you put a half ounce of OHT in the air side of the PAK... no air in system when you do it or you will be really suprised...open a glad hand on the rear and leave it open so you have no mistakes.. Oht is sold in small bottles by Spruce Mountain Surplus.. ACE

Wasn't the current recommendation to use Break-Free CLP for air pack lube?

On mine there is no air in the back of the chamber until the brakes are applied. Then air comes out,,,and all the oil that you just put in too,,what a mess! Is this right?
