Yanmar 2610d steering problem

aparker · Oct 2, 2006

My Yanmar 2610d pulls hard to the right when the 4wd is engaged. Does anyone have any thoughts about why this is happening. Also has a koyker front end loader. Thanks

Could be mis-matched tire sizes, more info needed. Did it just start happening, on hard surface?

Possably only the front right wheel has power to it. I would jack it up and see if you have power to both front wheels.

Because of the differential, there is only power to 1 wheel at a time, same as the rear, (without the differential lock).

what's your tire pressure? Have you checked the toe-in adjustment for the front-end?

Did this all-of-a-sudden start happening? Are there any unusual noises?

Will it engage/disengage 4WD?

Does it do it in 4WD, 2WD, or both modes?

We need more info....

Also, do like arthr31 said and check the tire pressure.............sure could/would be a cheap fix!

Pulling hard to the right would seem to indicate that only the right wheel is driven. I also agree that we need more information.

I just noticed the problem with the steering, although I just bought the tractor a few weeks ago. It only pulls to the right when the 4wd is engaged. No unusual noises or anything. I will check tire pressure and size, but since it only seems to be a problem with 4wd engaged, I think its something else.

Take it back to the dealer.

" I will check tire pressure and size, but since it only seems to be a problem with 4wd engaged, I think its something else."

When I said "mis-matched" tire size, I was referring to front mis-matched to rear, which would cause driveline "wrap-up", especially if you are trying to use 4wd on a hard surface. Keep in mind, these 4wd tractors are really only 2wd, (2wd is really 1wd), unless you engage the diff. lock, when they become 3wd.

I agree with Danny.......Take it back.

normde2001,

You are partially correct...Not trying to confuse anyone, but the machine will be Completely 4wd without having to use the diff lock ONLY if the tractor is on level ground...... But if the tractor "leans" to one side or one of the tires "dips" into a rut or something, THEN the wheels start to slip (and it don't take much to make them do that), as we know these are limited-slip differentials.

As long as the tractor is on a flat surface all 4 wheels will pull, as long as there is nothing wrong with the 4WD 'system'.

I think there is something wrong with the 4WD components somewhere in his tractor.

Another problem from a new owner. As he posted, he has only had the tractor a short time. Hopefully with a warranty!! Just curious Mr Parker, is this tractor a refurb??????

WHAT????? All 4 wheels will pull?? Where do you get this stuff?

I wanted to ask that Wayne, but I'm just reading as for now. Not feeling like posting as yet.

Travis, hold on a minute. Your uh... innocence continues to astonish me. We all (except you apparently) know these tractors DO NOT have a limited slip differential in the rear axle. (or in the front or middle either for that matter) Your "as we know" mis-states what everyone here but you already knows.

Norm isn't partially correct. It is offensive for you to say that. He is entirely correct here, as he always is so far as I have seen, and you could learn a lot more than you know now by listening to him.

A 'lean' or 'dip' doesn't cancel the fact that the tractor is 4wd any time the lever is engaged. If you meant to talk about all 4 wheels pulling effectively that's what you should have said. 'Limited slip differential' is nonsense.

Please - there really are people here who know far more than you do. Your contributions are often like this one, speaking a tone of certainty when you are clearly showing you don't know what you are talking about. You just watching and learning for a while would improve the Yanmar forum.

He's all yours, Wayne

Well, Wayne, theoretically, in a lab setting, under controlled conditions, with all the loads perfectly balanced, you could maybe detect tractive forces at all four wheels. I guess.

But, Travis, pulling a bushhog around the pasture? I don't think so! The standard, run-of-the-mill differential directs torque to the wheel with the least traction. To wit, one wheel in the mud, one wheel on dry ground, the wheel in the mud is the one that spins. Would that it were not so.

I'am taking the limited slip unit out of my tractor cause it ain't working correctly. It never locks all 4 wheels in so that they all pull . I'am going to install a spool . Anyone know where I Can get a spool for a tractor ?
