AC 620 with front wheel rubbing


Recommended Posts

Posted
I noticed this problem a while ago and now it seems to be noticeable on both wheels. I replaced both front tires and noticed that the control arms, holding the ball joints, are rubbing on the inside of the tires. Not a lot but enough that it is touching them. The tire size is the correct size for this tractor and the tires do not appear to be ballooned so I don't quite understand why there is no gap between the control arm and the tire. I also don't see any adjustment for this since the control arm is keyed in place. Am I missing something here? I am thinking of adding spacers behing the wheels to move them out a quarter of an inch to give a little clearance. There seems to be enough lug threads to perform this. Anyone else have this problem? Am I seeing wear or wheel bearing slop? Everything seems pretty tight and correct on the wheel bearings. Thanks!

not sure if it is possible but can you put the rims on backwards. The valve stems go to the inside.

It's not uncommon for the tops of the spindles to wear a little. Even though they are keyed in place, a small amount of slop can direct the crank arm towards the tire. I think this is one reason why they went to the stronger spindle assembly on the 720/9020 models.

Sounds like the new tires may have a slightly different cross-section. You could try a liitle more pressure to round them out. The shim idea seems like a good one too.

Be carefull adding some shims. As you push thw wheel away from the center line of the verticle spindle you'll add to the amount of room it takes for the tire to swing from lock to lock. Inother words you'll start hitting the deck with the tire.

I know my original 20-8-10 flotation tires hit the deck now so it might make it worse

On my 713S I was using the wide 6.50 turf tires. I switched from them to the 4.00 tri-ribs from my other tractor. When I did, I noticed that one side had a thicker spacer washer behind the inner bearing. Now the side with the thin spacer almost rubs while the other side has plenty of clearance. I need to add another shim washer to the close side.

Here is the tire that will solve your problem. In addition, shoulder is rounded which makes steering much easier. The "R/S" seen on tire ="round/shouldered". [img]/club2/attach/mikefox/P91200677.jpg[/img]

Carlisle Tire, T U R F T R A C R/S

White grease so tire rubbing doesn't cause smoke????? LOL

I wish I would have known that before I bought my new tires and mounted them (real pain to mount too). I bought Carlisle but not the right model....and I always thought R/S meant Rally Sport...live and learn
Posted
I thought that the R/S stood for really special since they have them priced like they do.lol

Update...I reversed the rim (valve on the inside) and added two washers on each stud. Since the rim holes are slightly beveled and the washers did not seat perfectly flush with the hub (stud diameters slightly larger at the hub holes) since the washers were tight, I ended up with 3/8 to 1/2 inch clearance now on each side. I'm sure that there is more of a shear load on each stud (200 lbs approx.) but it should probably be okay.
