Inner Tube Question

[Howard H.]

I was replacing a rear tire and inner tube on my JD 4840 this weekend.

The new tube had either a protective rubber sleeve that was pretty poorly made over top of the valve stem - or it was just a piece of waste rubber from the manufacturing.

It was separate from the tube and just slides over the stem like a sleeve with a "foot" on it about the size of a tire patch.
Anyway, I left it on there thinking it would be a little bit extra padding/reinforcement around the stem - but now I can't get the the stem to come through the rim. I hate to get rougher with it and tear it...

Should that piece be left on?

Some wheels have an extra large hole that requires that bushing. Extra parts, throw it away.

If your rim had been a bit rusty.. you needed it.. sounds like you answered your own question.

Can anyone explain how inner tubes are made? It must be simple as they have been around since the model T days.
