Did this today with help from the gas equipment dealer. I swapped out my dirty wheels with ones from a new computer.
They are now 4 wheel and the marking are different so choose your wheels. They use a "star" screw instead of the older Allen screws.
Undo the Allen screws on the side with the wheel shaft grooved end. The bracket just comes off. Now take a rod similar in size to the wheels shaft and shove it through the shaft hole, forcing the original shaft out.
Your wheels should be on this new shaft still in the computer. Now use a similar shaft that is less than the width of the INSIDE of the computer and do the same thing.
The wheels should now be on this shaft and can come out all at once(remove the totalizer, pry off metal cap covers if in place.)
You will need to swap like sides as the gearing is diff on each side.
Now repeat the procedure with the new computer, new wheels on short shaft, and swap your wheels out. Line up the replacement wheels in the old computer and get your original wheel shaft and push back into place, forcing the short shaft out.
Put the bracket with grooves back in place and move the wheels so the gears mesh, reset to 0, and line up the "cotter pin" on the other end of the wheel shaft in its groove.
Replace your totalize and you are done.
Here are pictures of newer computers showing the sides with the bracket you'll remove.

The bottom smaller pricing wheels just remove the cotter pin and slide up to replace.
Hope this helps someone
