Rockcrawler69 11 #1 Posted September 7 Hello, New to the forum. Love the wealth of information here. I picked up a new to me 520H last night. Crawling around it I noticed the left hub is farther away from the axle housing than the right. I believe the left has been replaced, it’s black so different color than stock. Is this spacing ok or is there a way to tighten that up? Share this post Link to post Share on other sites
953 nut 55,158 #2 Posted September 7 There is very little space between the axle and hub on an Eaton transaxle, yours look about correct to me. 1 Share this post Link to post Share on other sites

lynnmor 7,303 #4 Posted September 8 The 520H tractors have a plastic spacer because the hub runs so close to the transmission. When you install a hub, leave a bit of clearance. I think that I see an uneven amount of clearance on your black hub, it may be just the camera angle, jack it up and see if there is some up and down movement of the tire, there should be next to nothing. 1 Share this post Link to post Share on other sites
Bill D 1,916 #5 Posted September 8 Looks like the plastic spacer is missing. 3 Share this post Link to post Share on other sites
Ed Kennell 38,113 #6 Posted September 8 to the Like Lynn noted, the black hub does appear to have an uneven gap with the axle housing. I would remove the wheel and hub and inspect the axle for damage and try to determine why the hub was replaced. 1 Share this post Link to post Share on other sites
Rockcrawler69 11 #7 Posted September 8 Thank you. Yes, the black hub is uneven. I’ll jack it up and check. 1 Share this post Link to post Share on other sites
Rockcrawler69 11 #8 Posted September 8 Definitely excessive play on the black hub! IMG_8661.mov 1 Share this post Link to post Share on other sites

Ed Kennell 38,113 #10 Posted September 9 (edited) Afraid you need two new hubs and or axles. Maybe you'll get lucky and find some "mechanic" installed 1 - 1/8" hubs an 1" axles and the axles are not ruined. The good news...removing the hubs should be easier than normal.

Rockcrawler69 11 #11 Posted September 9 Thanks Ed and one can only hope! I noticed the black hub spacing when I bought it but $300 for a clean machine and a 60 inch deck I said I’ll deal with it later. Well looks like later came sooner. lol. Share this post Link to post Share on other sites

A $500 60" deck for $300 is a steal....and a free 520H. Just hope the "mechanic" has not worked on the 60"er. 2 Share this post Link to post Share on other sites

Ed I believe that all 1100 Eatons came with 1 1/8" axles and eight pinon rear differential.. Share this post Link to post Share on other sites

Yes, they did. but I wonder if that is an 1100. It's just hard to imagine they can be worn enough to be that loose. I've seen and repaired some bad hubs and axles but usually the keyways are just wallowed out. Share this post Link to post Share on other sites

Rockcrawler69 11 #19 Posted September 13 Thanks for the link Squonk Ed Kennell how does one tell if it’s an 1100 reared, aside from measuring the axle shafts? I’m hoping to tear into it this weekend and I’ll take some pictures as I go… Share this post Link to post Share on other sites
lynnmor 7,303 #20 Posted September 13 All 520H tractors came with an Eaton 1100 hydro, it is doubtful that a previous owner, that was too dumb to install a wheel, changed the transmission. 1 Share this post Link to post Share on other sites

Agreed. Hopefully any damage is limited to the hub and not the axle. Share this post Link to post Share on other sites
Rockcrawler69 11 #23 Posted September 17 Well Ed Kennell called it. 1 1/8 hub on the one inch axle. Share this post Link to post Share on other sites
