MF285 front end alignment issue

tg in VA · Oct 20, 2012

I have a MF285 with a FEL. Last spring the "pivot pipe" for the front axle broke. I ended up having to have the saddle reqorked, we got it all back together and now, whenever I turn the tractor to the left, the right front tire "heels" over and digs up the drive, pasture, yard, etc. This digging is from the outside of the tire. When I turn to the right, everything is normal, no digging with either front tire.

I did not have this issue before the collapse of the front end, which collapsed, by the way, as I was scooping a load of compost, the tractor was barely moving, so there was no real trauma to the tractor parts like there would have been had it collapsed while driving along in second or third gear.

Any suggestions?

Thanks

There are 3 things with alignment of front ends. Cars, trucks, tractors, doesn't matter. Caster, camber and toe.
Toe in is pretty simple. In vehicles, the wheels spread a bit and it saves tire wear as well as allowing your vehicle to track down the road straight.
Camber, is the tip in of the wheels to allow the full amount of tread to hit the road at all times.
Caster is the ability to easily return the steering wheel to center. If you get tire wear or "digging" into a corner, this is where you need to look. It is not possible to weld or repair a piece without throwing off one or more of these angles. Replacement of said broken parts is the only way to get back into factory specs properly.

Have a good look at the square box section of the right hand side spindle housing, and see if it has a bend in it, where the king-pin or spindle housing attaches.
It may be noticeable as you look at the opposite side, as the spindle will seem to "lay back" towards the rear of the tractor, more than the opposite side.
If this is the case, mounting the spindle in a suitable press, and "heating" the bent area with a blow-torch and applying ample pressure to the spindle with a long bar, may do the job,
let us know what you find,
Evan.
