 Topic: Center Hub
Posted: 17 Aug 2024 at 12:22am |
|
I bought new rims for my WD45. Does anybody have any ideas to get the old center hubs off of the old rims? I have soaked with some PB Blaster and used a sledge hammer with a board across the bolt circle.

Strike down on top of one of the four eccentric areas, not in the center.

Assuming your working on the rears….make sure the eccentrics are loose. There is a rib on the outer surface of the center that the eccentric housing has to come out of to get it apart.

Im4racin, that is most likely his problem. The eccentrics are probably rusted up so he can't loosen them.
Remove the rim from the axle and lay the wheel on the ground facing up. Remove the nuts from the 2 bolts that connect each eccentric to the rim. Find the heaviest wooden beam you can handle and repeatedly drop it on the wheel center around each eccentric. Keep doing it. When you see a gap form between the center and eccentric, you are getting close. Eventually the center will drop out. Then make sure you pick up all of the little parts - you do not want to lose them.
To loosen the eccentrics, cook them! In the winter, I put mine in the wood stove for the night. In the summer, I put them in a little firepot.

I bought a 40" (3/4" drive) breaker bar and a 3/4" (3/4" drive) 6-point impact socket. I loosen them while the rim is still mounted on the tractor. I haven't had one that I couldn't loosen (yet).

Thanks for the help. I didn't have the eccentrics loose. That made all the difference.

On my other rim the eccentrics won't budge at all. I've been soaking them for a couple weeks now and they still won't budge even with an impact. I'm going to be having a bon fire in a couple of weeks should I just throw the whole rim in there and let them cook? Do you think a tractor shop, truck shop or machine shop would have a bigger impact or some type of machine to break them loose?

You do not need to soak the eccentrics to separate the center from the rim. Lay the tire on the ground and remove the 2 bolts from each eccentric assembly. The strike down on the wheel center with a heavy block of wood around any eccentric. Eventually you will see the eccentric separate from the center - then move to one of the others beside it. Once 2 separate, the rest will go and everything can fall apart. The seized up eccentrics can then be put in the fire to help work them loose. Have done many this way.

I thought the eccentrics held the center hub in. I couldn't remove the other hub until i loosened two eccentrics completely and the other two about a third of the way then it just fell out.

The eccentrics do hold the center to the rim, but once you remove the bolts on each of the 4 sections, it's only decades of rust holding things together. Once you break the rust apart, everything will be in pieces. After that, you can work on getting the eccentric cams loosened up. As mentioned earlier, putting in a fire helps a lot, then I take out the pin and bead blast everything before reassembling.

I use a piece of 2x6 laying across the wheel and put a short piece of 6x6 in that to hit with a maul. As stated, the eccentric bolts need to come off first. As stated, watch ESPECIALLY for the eccentric BLOCKS when the wheel falls out. You don't wanna lose them!! $$$$ Try and take the snap rings off the eccentric pins BEFORE you throw them into the fire. The fire will weaken them. You can wire wheel the eccentrics afterwards or get a sand blaster. It's a lot easier.
For bolts you can't get loose? Using a six sided socket and a breaker bar, put a piece of lead pipe over the end of the breaker bar. LOTS of force that way. I have snapped a few breaker bars that way, but that was why I bought Craftsman.....They replace them!!
