Re: JD X500 Steering Gear fail
Had a better look at this last night in the garage. The sector gear teeth tips have worn off on one part of the sector gear, allowing the pinion to "skip" when it gets to that part of the sector gear. Specifically, about 15 degrees left turn.
Now, I also noticed that the short shaft that mounts the sector gear to the support has a little play in it. I don't know if that is normal or if a bearing or bushing has worn allowing the sector to move slightly away from the pinion in some spots. That could answer a lot of questions as to how the sector teeth got worn off. As mentioned, I did put an additional washer to take up any vertical slack, but which still allows a little side play. I suspect the bearing failed and the rest is the result.
I'm going to order a new sector gear and replace it, along with the bearing that is is mounted in. The pinion looks good. I am also going to see if I can somehow make the sector to pinion a closer fit.
Thanks for the comments and support.
