Hey guys, I have a model 601 yard machines tractor and my steering is slipping. I took a look under the front end of the tractor and noticed that the steering pinion was slipping off of the steering gear. Upon inspection of the pinion I found that it had been worn down, so I ordered a new pinion. I put on the new pinion which definitely improved the situation but it does still slip. Any ideas what would cause this? It doesn't sit tight against the steering gear but I'm not sure how to fix that. Thanks!
