Wheel Horse rear axle hubs do one of two things. Either constantly
come loose, or attach themselves permanently to rear axle. I've
buggered them by pounding on them, pulled snap rings loose from the
inside of the axle with prying, and snapped them with three jawed
pullers. Heating will help, but that always ruins the paint at best,
the seals are also in question afterwards.
Not too mention the just pain in the butt it is to do all that stuff.
There has to be a better way. Tell you what, there is!!!
Take a 6" square piece of 1/2 steel. Drill 6 appropriately placed and
spaced holes. Tap the center one to 1/2" fine thread. Weld a 1/2" fine
thread nut over the center hole just for good measure. Grind a small
taper on the end of a 1/2x6" fine thread bolt. Cut off the points of
the "square" for good measure. Using 5 bolts of appropriate size,
attach to rear hub. Just set center bolt snug. Even up pressure on all
6 other bolts. Using a 3/8" impact on low setting, watch the hub slide
of the axle harming NOTHING in the process.
Takes about a minute to attach the puller, pull the hub, and disengage
the puller from the hub.
Allways replace the keys and the set screws If a hub has movedWell' I guess I got lucky as I went ahead and replaced both my brake shaft & axle seals and all went very smooth. I sprayed mine with PB blaster several times for a few days before starting the job. I also replaced my woodruff key because it had the edge smashed down where the bolt was so over tightened at some point and it had a bit of wear all along the edge too making it a bit narrower so I suspect it came loose and was driven at some point? Key don't look ground down intentionally or at least I see no grind marks but its weird that its about an 1/8th narrower just along the edge like it was indeed narrowed to slide into the hub slot easier. I bought tractor used so I'll never know for sure? If it was intentional maybe for future hub removal, if so it sure worked for me as it didn't take much cursing to get it off. I did put anti-seize on it for any future repairs needed.
