OK Ive got the old>>>BIG case maxmod truer...I have a problem with it.. When it cuts tires it cuts them out of round....

Sooo I got out my camshaft degree micrometer kit...Here is what I found..

The metal(steel) shaft seems to be dead on... However at the end of the metal shaft there is this aluminum collar with 2 pins on it that the arbors slip fit onto...That has some substantial wobble...The threaded rod that goes into it also shows wobble...I removed the threaded rod and it cheacks ok... So my problem is with the aluminum collar that the arbors slide into...

My question is has anyone ever disassembled that shaft and removed that arbor mount aluminum piece....Im not seeing exactly how this thing attaches to the metal shaft????

PArt 2 of this question would be...If I bought new arbors say from Murdock does it only come with the arbor itself or does it come with this piece????

I kinow I really need to talk to maxmod but Ive been unable to get in touch with him...I was hoping some here could give me an idea of how to remove that alum part from the shaft itself....Id like to check it out completely before ordering parts...

Here's the info for Maxmod Products.
He has parts to fix the machines.

The arbor mount is pressed on. You can have the shaft turned down to accept 5 mm arbors like Murdock or Hudy sells. Check out my Maxmod

cool...I may remember that for the future...I got a hold of maxmod last night....he is going to rebuild the upper portion of mine for me...

thanks for the numbers and help...

depending on how this works I may somewhere down the line switch to the murdock version...seems like an easier alternative to shipping it back..

i pressed the dowel pins out on my adpters and now i chuck the wheel up and rotate the wheel\tire until it spins true.. then make the cuts.. the threaded shaft really doesn't have to be too perfect,if anything you could leave that a tad loose then tighten the arbor down.. you could also take the whole shaft off the machine with the aluminum piece that is pressed on and take it to a machine shop and have them face just the aluminum to make it run true with the steel shaft.

It sounds like this unit was dropped at some point.

good luck still the best tire truer out there!!

Well maxmod told me how far to disassemble and said $30 to remachine a new part and install it..so thats cheap enough for me...

It was not dropped...I think the previous owner used to LIFT the unit by the arbor to carry it...
