 Topic: Dealing with Power-Adjust wobble
Posted: 01 Mar 2012 at 6:48am |
Anyone ever have problems dealing with aftermarket power adjust wheels not rolling straight? Is there a good way to correct it? I have a D15 with 26" wheels and I'm haveing trouble getting the one side to track straight. The eccentrics don't have much resistance when you bind them against the rail. Maybe the cams are worn or possibly a defective wheel? Thanks for any help on this. Eddie

I would jack up that side off the ground, loosen the eccentrics so that you can spin in and out the rim and let it find it's sort of sweet spot in the general location that you need. Then tighten it up and see if it helped. If it still wasn't correct you may need to remove that rim and install it on the other side to be sure it's the rim and not the center or eccentrics. That would be a pain but would tell you where the problem is.

Old mechanic said he would always take a coke can/bottle, lay it close to the tire, then rotate it and slowly move it in closer to the tire as it was rotating. When it started to rub in one place, you could find out where the tire was out of line and adjust it. I guess if you have a hardware problem, this won't be much help, but if it just needs to be lined up it could work.

Loosen youir eccentrics. and spin the Wheels all the way out. set the stop where you want the tire. Now spin the wheel in untill it contacts the stop. let the tractor move in the direction your going a few feet. Last tighten the eccentric cams starting at the bottom. Your wheel should run straight now. Take a close look at it and make sure the tire is completly seated all the way around. Its more likely the bead is not completly seated than the rim is not runing true.

Thanks for the advice guys...this was out enough that I even put a dial on the wheel center to make sure it wasn't bent. I got everything against the stops and locked it down, and it rolled out pretty good, but when I got it out to drive it, it popped loose on the ecentrics and wobbled again. I'm apparently going to have to replace the cams so I have more tension against the rails.

When you tighten the cams they need to go all the way against the stops. when you do that they overcenter and can't loosen.

If your blocks in the eccentrics are worn, the rim will not tighten up properly. you can buy replacements from Jim Danforth, Tony Carbaugh and others.

I had problems with aftermarket rims for a CA. The rails were not welded on correctly. Sent them back and got replacements.
