Air Pack extra part

[rhuther]

I rebuilt my air pack and now have an extra part. The part is not in rebuild instructions and I hope some one can tell me where it goes.

I don't recall seeing a part that in a long airpack, I have only repaired/rebuilt a few of 'em. Maybe someone more experienced will chime in

That doesn't look like anything out of a long or short air-pac.

That part goes seated inside the outlet plug (pic below).
Possibly to help keep the return springs centered in the cylinder bore; prevent the coils from shifting to one side and touching the cylinder wall when fully compressed.

Not a crucial part IMO and it seems like some of the (long)airpacks came without it. At least the TMs I have don't show it.
Now to find out if this was added as an upgrade on later versions; or if it was the early models which had it...?

Thanks I was starting to second guess myself thinking I got it mixed up from something else.

I've rebuilt 6 long style air-pacs (from 1954 to 1976) and none had this "spring guide ? " on them. My early manual doesn't show it either. Must have been some sort of up-grade. I will be rebuilding my 1988 long style air-pacs this summer. Maybe they will have it in there.

My 88 duece's long style airpack a had these cone things in them to help center the springs also. A few of the rebuild kit parts didn't fit either like the gasket between the back cap and the air cyl body. There must have been a few small differences in the newer of the old long style airpaks.

Well then, it must be a late model upgrade.

I have found that some of the gaskets don't fit because they are dried up. If you soak them in hot water they will be restored to their original size and be pliable again.

Now that sounds like a good trick. That's one of the reasons I don't like using "NOS" gaskets. Especially ones over 30 years old. Also I never trust oil seals and 'O' rings over 20 years old. Unless there made out of "Silicone" or a good "Neoprene" or "Viton" .
