@richard-rogers I'll move this to a technical forum for you.

Great, Thank you  :o)

I remember running into the same situation when I first started messing with these one ton trucks (circa 1990). I bought a couple of rusty, dilapidated '28 LPs and I couldn't for the life of me get the rim (with the tire) apart from the felloe (the inner rim that is connected to the wooden spokes).

Soooooooo, I went to the farm where I bought my trucks and I talked to the grizzled old farmer about how to get the rim off the truck. He said that he didn't know. He always took it to the mechanic (Earl Malech) down the road.  (big sigh from me). AND, here's his address!  He's still around, but in his 90s!

I went to see Earl a few days later and he was very gracious with this little whipper snapper. He told me to:

1. Jack up the wheel until it is off the ground.
2. Remove the 6 rim keepers.
3. Turn the wheel so the inner tube stem is at the 12 o'clock position.
4. Take a small sledge hammer and give the outer rim a whack on the backside (under the truck). 
5. The rim pops off the bottom and then you lift the rim to get the inner tube out of the felloe.

Then, he asked me if I wanted to buy another 1928 LP truck that he had in his barn!!! The wood spokes were in GREAT shape, he only wanted $500 for it and he said it ran. I passed on his offer and have kicked myself many times for not buying that truck. Such is life!

I found out later that it is good to use a short length of 1x4 wood that is set against the rim and hit the wood with a 3 pound sledge.

I have also found that if the outer rim is not truly round (aka bent), the rim takes some real hard whacking to get it off the felloe. When I realize that the rim is not coming off easily, I set a bigger sledge hammer to rest against the outside of the felloe to give more mass to the wheel and help prevent undue stresses on the wood spokes.

Now that you've got the rim and tire off the truck, you'll want to know how to get the tire and inner tube off the rim. 😉 There's a great PDF in the Technical Resources area of the website (club members only) that is titled 1928 Tire Change info.pdf and you navigate to it from the club's home page: vcca.org > Resources (Forms downloadable) > Vehicle-Technical-Resources > 1912-1928-4-Cylinder-era

This article was originally in the G&D magazine and it made the job of changing a tire WAY easier than what I had been doing.

Enjoy!  Dean
