jsoluna 472 #51 Posted March 29 (edited) Adjusted the backlash as advised. Took a small amount of play, maybe 10% out of the steering. Looks like most of my gains will be by adjusting/removing shims from the fan gear shaft mount. There is significant backlash there with everything else snug. Will deal with that along with the missing grease fitting and the misaligned quadrant next season, most likely. Edited March 29 by jsoluna 3 Share this post Link to post Share on other sites
jsoluna 472 #52 Posted 6 hours ago Just couldn't help but take care of both areas of backlash adjustment, and repair the broken grease fitting. Made a significant difference, but still more gains to be had. 2 2 1 Share this post Link to post Share on other sites

Never could figure out why this issue was never caught, and fixed, at the dealer. What I did was center the quadrant and readjusted the tie rods to the proper toe. It wasn't my preferred fix but at the time. Steering wheel ended up way out of alignment but just learned to live with it. Replacement steering shafts are sometimes hard to find. Guys want the entire 520 front end to have on other tractors. 2 Share this post Link to post Share on other sites

Yeah it's a shame it got through production and the dealer pre-delivery inspection/setup with it like that. I think the simple fix is to just cut the fan gear shaft somewhere in the middle, reorient the two halves, and weld back together with a sleeve over the joint to reinforce that area.

It's so far off I had actually thought it served some purpose. No way quality control let something like that slide! It's on the 523-H and so far as I can tell it doesn't affect the steering in any significant way. I guess I need to check the radius both ways to see. Probably turns one way a little sharper than the other at the stops. I set the center of the setup on the middle tooth in the fan and aligned the wheels off of that at the links so that's probably why it doesn't show up. All of my other swept axles are 1990 models without the reduction setup. Edited 1 hour ago by kpinnc Share this post Link to post Share on other sites
