Front wheel camber

TCBoomer · Nov 7, 2004

I've tried searching and came up with zilch.

Anyone know why the front wheel camber for TC series is set on the positive side?

My 21 looked odd with as much camber as it had. My new 24DA also is set on the positive side, but is not as noticeable...possibly due the tire size.

Could it be related to stability /forums/images/graemlins/confused.gif

TC, I found the same thing on my 33. I checked it as per the manual ;width of front compared to rear of the front tires. They were off by 1 1/2 inches. I guess they don't check'm during assembly. Quality Control ?

David, it sounds to me like you are describing toe-in or toe-out rather than camber. Camber is when the top of the tire leans inward or outward. Negative camber (tire leans inward at top & outward at bottom) on cars is common to improve handling in corners. I can't think of an instance of positive camber unless it might be on road graders where the tires lean as the grader turns. TCBoomer, do you mean your front wheels are wider at the top than at the bottom?

I'd expect a slight toe-in on our tractors, but I don't know if 1-1/2 inches is normal. That sounds like a lot and would cause severe scuffing on the tires if driven on pavement. /forums/images/graemlins/confused.gif

I'm thinking that 1-1/2" isn't normal. Couldn't find anything in my TN55-TN75 manual, but peeked in my combine manual and found a toe-in tolerance of 7/16 to 19/32"(11 to 15mm). That's for 24" rims. Can't imagine it would be more for Boomer size tractors.

Looking forward to hearing the final verdict. Good luck.

Just looked in my combine(CaseIH 1660) manual again and saw where 16" wheels toe in is 9/32 to 3/8"(7 to 10mm).

They also mention a power guide wheel toe in of 1/4 to 3/8"(6 to 10mm).

If you have MFWD, I'm thinking the power guide wheel adjustment is gotta be getting close?

I better quit throwing out numbers and hope someone who really knows replies! /forums/images/graemlins/confused.gif

MnKurt,

I am from Rochester, Mn. What city are you from if you care to say?

jinman, you're right , it's caster. You could look at the front of mine and the wheels were pointed in different directions. Easily corrected though. It's a simple quality control issue. No excuse for them to be that far out (1 1/2 in.) on a new tractor.

Hey Murph:

My address is Rothsay, a town of about 500, but an easier town to recognize is Fargo, ND. I'm 40 miles SE on the MN side.

Not caster either, it is toe in (or toe out). Should be in the range of 0 to 3/8" of toe-in for most compacts. Note this info does not come from any manual, but it is better to be in that range than outside it. Camber has been accurately described, caster is the relationship of the steering swivel axis to a vertical line. Of the three, toe in/out is the only adjustable value on tractors.
