hub removal question

[briankd 817]

worked on getting hubs off my c-120 to replace axle seals have a puller on them and heated them and won't budge. seen on here someone talked about using wax to help them come off ? i got into my wife's sewing wax and while hot ran block off wax around axle it seemed to draw it in and at one time had the whole hub flaming from the wax burning off. how does this wax thing work ? never used it before. i really don't want to break the hubs if at all possible  i have enough  pressure on puller now that any more it may snap em. i did my 857 and them hubs fell right off but not theses ones . Thanks Brian

 

 i thought of using one of them bearing splitter pullers they will fit tight around the axle behind the hub but my buddy has one but won't be till next week before he around to borrow it thought i could get them off without it

Show us a pic of your puller set up.

all i have now is an automotive harmonic balancer puller. have 2- 3/8 bolts going thru the 2 of five lug bolt holes. that is all that the puller will line up with hole wise

 guess if they won't come off after i soak em for a week guess i will cut them off split them into 2 halves and go and find 2 hubs and put them back on using never seize.

thought making up a puller but will prolly never use it again after this one here.like i said guy i know worked on wheel horses back in the day he may have on he used but he at tractor shows till next week.

You better stop now before you break a hub.

You need equal pressure around the hub (all 5 lug bolt holes) like this:

yea exactly going to show in  portland indiana this week will see if i can find any hubs of any kind close  to make a puller. and may run across some wh hubs

Remove the set screw(s) and look in at the key.  If the groove inside the hub wore so that the key is no longer in line with the keyway, you will not be able to pull it off.  If you can rotate it with a hammer, that may be the problem, so then tap it to align it and try pulling again.

Oh Boy!!! those da** hubs!! they and steering wheels are the bane of us horse lovers!

 

I got disgusted and got on the mill and lathe and with a piece of 5/8" metal plate and a 3/4" bolt I made a puller to match the 5 holes --- even then with my big 3/4" impact driver with 130psi hammering it took some 10-12 min just creeping off. So, like the fellas said get a much better puller, that cast iron is somewhat brittle and it WILL break.

You might want to add the hitch pin that goes through the transmission rear-end housing!

heres my lazy solution - not broken a hub yet, but had to change bottle jack to a 6 ton one

 

[elcamino/wheelhorse 9,355]

@meadowfield Did you attach the bottle jack in any way or does it just set in the puller and a aligned by sight? 

[woodchuckfarmer 333]

Ive got a puller something like that only I used a 20 ton jack.

[KC9KAS 4,741]

@meadowfield It looks like you only have 3 pieces of threaded rod between the hubs...Is that correct?

[ohiofarmer 3,276]

 Brian, I have an old hub to pull yours with. You are not that far away from me according to the member map. Bring over your tractor and we can get the hub removed

Only got the pic. I have to put them in pieces to fit the bottle jack in. But can only fit 4, those rods are under serious tension and snap at around 5 tons!!

[meadowfield 2,595]

just in case you wondered why I knew they snapped...

It's a lot easier with some heat. But, you will then need new seals.

btw i did get the hubs off  spent 2 hours on one had it cherry red with a torch and still didn't wanna move but i got one off and broke one.

I tried this works great.

That is an ingenious contraption @Dennis Gintowt!!! The bar has now been raised significantly!

 

I just found this post today after snapping a hub last night with a 2-ton gear puller driven with a 20v Dewalt impact. Don't try it this way:

If you use a puller this worked for me. tighten the puller 20/30lbs, heat the hub, pull and hold the axle out even if its only an 1/8", then hit the screw in part of the puller good and hard. the shock load will move the axle a tiny bit. The shock is what gets it done. As it moves the sound of the hit will go from high pitch to a thud. rinse and repeat. Also grind the point off the puller. it may swell the end of the axle.   What Iynnmor said it very true. Mine were really wallowed out. Hope this helps. good luck.
