wrong airpack on deuce

[ctmustang]

wanted to pick some of your brains. why does this air pack on my deuce not look like other deuce air packs? master cylinder looks rite best I can tell. have a brake problem and need to rebuild airpack but I realized it looks different from other 2.5 ton airpacks I have seen.
any ideas?
thanks yaw

There are 2 styles of airpacks on deuces. A new and old style (length is different). Be sure to get the right rebuild kit if you go that route.

 

[ctmustang]

is this the old or the new>
thanks again

[tomesee1]

this is the old style

 

[ctmustang]

is it a problem to install the newer version? would it bolt rite up or need modification?

 

[Recovry4x4]

It's the old 80's style but my Stude's came with the long one with the studs on the cover. My Studes are all dated 1953 and I'm pretty certain that the one off the M108 was original, still had strata blue paint on it! No mods, they are completely interchangeable.

 

[tomesee1]

the new style is longer not sure on mounting though

 

[ctmustang]

I was hoping to lube the pack but unless I'm missing something there's no way to lube this one- no square plug on the back. am I wrong? any pics outthere of the newstyle installed on the truck. may want to just swap over since valve in my pack is stuck.

They are interchangeable. No need to worry.

 

[Recovry4x4]

You can lube it, pull that "J" shaped air line off and lube away. Can all of you folks saying the shorter one is the older one, tell me where you got that info? I've been around these trucks along time and many friends been around them even longer. I've never seen an old truck (gasser) with one unless it was a retrofit. I'm pretty certain that the short one without the rear studs is the new one!

 

[gimpyrobb]

Yeah, not too many of the little can ones out there. Many times more of the longer ones. The longer ones are the old style.

 

[dabtl]

The 'short' one is the new one.

I read, here, that the rebuild kits for the airpack were the same for the old, long, and the new, short, airpacks?

Same down here!

I think you had this Q. already cleared, here: http://www.steelsoldiers.com/deuce/9695-m35a2-airpack.html

Kenny, you are right the short one is the newer one. The NSN's are different for the rebuild kits too.

 

[hndrsonj]

Just to clarify a bit. The NSN's are the same for the Hydrovac's, it's the part numbers that are different since they are interchangeable. NSN for both is 2530-00-040-2188 however the newer short one has p/n: 12368255 and the older long one has p/n: 8345003. There are two different NSN's for the long/short rebuild kits, however, I can't tell which is for which hydrovac. I would think any of the dealers could tell which fits which. (I think the 2190 is the old one).

 

[dieselsmokem35a2]

Just to add my two cents......I had found a good deal on fleabay about two years ago on a brand new airpack so I bought it for spare parts in case the one on the truck ever went. Even though there was nothing wrong with the one on the truck, I recently swapped em out. I thought I would switch it out just to see if it made a difference. The one that was on the truck was the long version. The one I bought and put on was the short version. The swap was a cinch and everything was very interchangeable. The breaks felt much firmer afterward but that could just be from new brake fluid, bleeding, etc. I couldn't tell you though which one is the "new version" or "old".

 

[ctmustang]

thanks

Thanks everybody for your response. nothing like the words of somebody that has been there aand done that-whatever the case may be. And a big thank you to Deuceman51 for some great-straightforward advice that he put on me in English so I could understand!

Glad I could help out, let me know how it turns out.
