How to remove Massey 6180 Cast Centers?

[GHuggins]

Pretty much what the title says. I took two of the 4 bolts completely out then loosened the other two about an inch. I've tried rigging a puller - never could get a good footing for good pulling. I've tried looping chains to another tractor that I had in place for lifting the wheel off and using ratcheting log binders - only pulled the 6180 sideways since I've got it up on blocks partially. I tried using an air hammer with lots of lube to drive the keyway both out from the inside of the tractor and in from the outside trying to break it loose - wouldn't budge at all - thought if I could atleast get the keyway out that I could take all of the bolts out and try to use the tractor to "shear it off"... Even used the loader of the other tractor to "rock" on the wheel assembly - again, didn't budge.

Only thing I haven't tried is heating mainly because I don't have any gas in the bottles plus didn't really want to screw the cast iron up any.

Trying to get the right rear wheel and center off together to get better access to the trans side panels - don't want to have to crawl around underneath dragging things out a lot longer than need be :/

Anyone know the trick?

Is there threaded holes in the hub with no bolts in them? Should be.

Clean these threads/ holes and lubricate them well. These are for push off bolts, run bolts in these holes until they go against, make them fairly tight, smack the wheel with biggest dead blow hammer you have.

If this fails, install the 4 bolts you removed except leave them loose,say about an eighth inch gap from tight, and proceed to drive tractor, while steering lock to lock . No need to go fast and shouldn't hurt anything.
Drive around in this manner a bit should break it, basically it just needs a good shock and it will be free

Don't try to drive key stock out, looks like a roll pin holding it in place. Also doesn't look like you have push off holes so disregard what I said about that unless there are push off holes in the center dish

There's two more holes there that I thought were push off holes originally and even ran two bolts down into them until I finally took a light and looked - pretty sure they're just attachment holes for extra weights or something else because they didn't appear to go through to the cone. Really hope I don't have to take it back off the blocks and drive it around - Had to use two tractors to lift the rear end up and put them there in the first place If I have to then I guess I have to though...

Pick about in those holes to double check that first. Most all manufacturers of that style hub make provisions for removal

Well, I was being a blind dumbarse - those are push through holes Went out after my last post, found a tap since the holes were buggered - which is why the bolts weren't going through to begin with, tapped out the threads and using a long ratchet since my junk milwaukee wouldn't do it - finally got it broke loose and slid right off... Kinda ticked at my own oversight and long waste of time, but hey - it's off now...
