How To: Trailer Hub Conversion/Upgrade For 520H

Recommended Posts

looks really good! 
when i did mine i welded the hub spindle to the WH spindle, i would imagine your method is preferred by most people because its bolt on. 
do you have any side to side play? from what it looks like in your third picture the WH spindle protrudes from the hub bearing.

There is no play side to side as these are tapered bearings.  The third picture just shows the loose nut and wash on the end.  Once tightened, the dust cap provided with the hubs fully covers the nut and cotter pin.  The hubs go together like they were meant for these spindle.

Thanks for the nice explanation! I'm glad that I suggested this option to you. It makes me all the more anxious to heal so that I can get about again and maybe try a hub conversion on a 5xi.

Looks like a nice setup. Where did you buy the wheels from?

I'm thinking of going this route on my 520H only because my original front tires are shot and I kinda like the look of the bolt on setup.  I would use some kind of acorn nut to hide the stud threads though. I thought there was a swap for the front spindle from another wheel horse for the 520 that allowed for the bolt on swap using studs that threaded into the hub, like the old VW's if anyone remembers those.

 

Kudos to Rexemouse for the use of a Hemostat to clamp off the hydraulic line... we ain't dealing wit no shade tree mechanic here boys! ;-)

I wouldn't do this to my 522, but my SB-421 is a definite candidate.
Thanks for the tip.

Tapered bearing trailer hubs are the way to go. I did my C-120 in 1989 bought hubs spindles wheels with tires from Northern Tool. I've only had to tighten the spindle nuts one time since.

Do you have a front photo? I’m curious of how much wider it made it

I just happened to have a trailer set under my bench, hilarious! I’ll buy these AG tires and run with it.

I added about 3/4" width to each side from the original wheel stop to the backside of the trailer hub..

These are 3500 # spindles 1 3/8" bearings on the back side. The total width of the front tread is 36".

I cut the trailer spindles 3/4" past the rear seal area. Then drilled the spindle 3/4" diameter, cut half of the WH  spindle off.

I cross drilled the trailer spindle 1/2" on one side between the bearing surfaces and welded to the end of the WH spindle..

The back side is also welded to the original spindle.

I've done the same with my C-121 Black Horse ploughing tractor and C-125 general worker.
