Steering gear adjustment

Recommended Posts

How do you adjust the steering gear? My 606 will only turn right!? Can't turn left because it runs out of splines

Here is the manual with parts list.

 

Remove the cotter pin and shims from the rear of the lower steering shaft #34. See if you can push the lower shaft forward enough that the gear teeth will clear each other. You may need to loosen or remove the 2 bolts holding the support casting #28 to the frame so the gears will clear. Center the steering wheel and front wheels/tires and then mesh the gears back together. The fan gear should end up straight up so left and right turns are equal. Add enough shims at the rear of the lower shaft to pull it back so the gears are very close to tight through a full left to right turn. You need to end up with a few thousandths clearance between the gear teeth through the full travel so they don't break in use. Reinstal the cotter pin and add grease.

Check the bushing #29 in the cast support for excessive wear which may be causing some of your problem.

Garry, If I may, I would add to loosen the set screw in the thrust collar on the upper shaft and tap it up as you push down on the steering wheel, and then tighten the set screw.

I suspect wear in the upper bushing and tower parts may allow the gears to jump when turning hard.

You can do that first if they are adjustable. Most are not. Give it a 1/16" - 1/8" toe-in which is the front closer than the rear of the tire.

I believe that I have read here that a batch of steering fan gear assemblies made it out of the factory not welded straight (the steering fan gear should be 180 degrees from the front steering triangle). If you just cannot get it adjusted, this may be your problem. If this is the case it can be cut and re-welded or obtain a new one.

 

Also, I dont know what years they started welding the fan gear to the lower shaft, but yours may be attached with a roll pin and if its wallowed out or someone re drilled it it could be way off center.

Okay yeah I slide the lower shaft forward to try and center the fan gear but when I did that the wheels are turned. So it looks like the fan gear isn't in the correct orientation on the lower shaft. I will try to get a pic tonight

My 1978 c161 has the same problem, fan gear not oriented properly before welding. It has more travel to the left than it does to the right.

most of the Wheel Horse tractors I have driven have had some difference between the left and right turn radius.just not enough to make a big difference or to worry about.

Must be one of the NASCAR models, those stock car drivers are generally turning left!      :ychain:

Well we just bent the "tie rod"... which was a piece of 1/8" all thread the previous owner had cobbled together.. gives me a good reason to fix the problem now

You mean 3/8" rod ?

 

I used that on my one 520 that has the non-swept axle.

 

So far it has not bent but I only use that machine for mowing and tilling.

No its 1/4". The previous owner had no business even messing with it. I'll take a pic when I get home. It's a mangled mess

Yes, that is bad.

 

I guess it sort of works.

Likely some new MTD's come similar to that.

 

I did this. Could be made stronger but so far it works.

Hard part is finding fine thread rod.

The tie rods on my 69 Raider twelve are like the ones above. Have been on there about 20 years. Probably be better if 

they were bigger diameter but has worked.

      On my D200, when I turn the steering wheel all the way to the left, it has a tight turn radius, but when I turn it all the way to the right, the turn radius is significantly wider.
       
      The tie rods appear to be adjusted evenly.
       
      Anyone have a similar problem and what was done to fix it?  The steering does have quite a bit of play, at least 1/4 to 1/2 turn of the wheel.

      Okay, so I just know just enough about engines to do basic care & know when something is wrong.  I have what presented as a hydraulic leak on my 416H with fluid spraying everywhere from under the center of the tractor and it is really only significant when the PTO is engaged.  I took the mowing deck off today expecting to find a cracked hose or loose fitting.  Wrong!  Instead I found fluid coming out from the steering shaft on the opposite side of what I am finding is called the "steering fitting lube" piece on the Toro parts website.  So where it shows part #7 going in the fluid is leaking out of the other side.  I'm really at a loss on this one.

      I need some advice. Worked all afternoon and was unsuccessful at removing the steering wheel from a 1961 Wheel Horse tractor. How is the wheel attached to the steering column?  There appear to be two holes where I suspect that the wheel is secured, but I cannot find a way to loosen any type of a fastener. Has anyone had a problem with this? I have a wheel puller attached but that wheel is really on there. How do I get this off?
