Nick Jones Posted July 3, 2012 Share Posted July 3, 2012 Me too. Flying-saucer type tool made up and attached via wheel studs. I wound the jacking bolt up as tight as I could get it with a 3' breaker bar (and it's a nice fine UNF thread with plenty of grease) and.......... nothing happened. I beat on it with my biggest hammer for a while.......... nothing happened. I poured a kettle full of hot water over the hub and beat on it some more........ nothing happened. Added a piece of scaffolding tube and managed to tighten it a bit more....... nothing happened....... beat it, hot water plus beat, big blow-lamp plus beat........ nothing - except the flange is well bent now. Hate them..... I'm told they do sometimes come apart!Nick Link to comment Share on other sites More sharing options...
Lord Sorbington Posted July 3, 2012 Share Posted July 3, 2012 Often, a 20 tonne press isn't man enough to shift those flanges.I've heard of people 'shocking' them off (whacking with a big hammer) but be careful not bend the flanges or damage the stub axle.Any decent gearbox or transmission place should be able to press them off for you, or get exchange ones from the usual places.

Andy Borris Posted July 3, 2012 Share Posted July 3, 2012 Didn't someone suggest taking it for a drive with the nuts loose?Andy Link to comment Share on other sites More sharing options...
beefertoo Posted July 3, 2012 Author Share Posted July 3, 2012 ahh so its not just me then.... seriously though i only want the flanges and the bearings are scrap anyway. they are not on a car so cant try that method but will try hot water or a blowlamp though.craig Link to comment Share on other sites More sharing options...

It got to 20 tonnes - and nothing happened - except the press relief valve stopped it going any higher.....Nick Link to comment Share on other sites More sharing options...
piman Posted July 3, 2012 Share Posted July 3, 2012 Hello Craig,I've done three or four so far, only one failure which was an old hub with a split pin drilling, which collapsed and ruined the end of the spindle. I use a disc of 3\4" steel bolted to the hub with four nuts and a two leg Sykes Pickavant puller, it has about a 1" diameter lead screw. Screw it up tight, a few wacks on the end of the lead screw with a 2Lb ball pein hammer, tightening as I go then bang, it lets go. I don't believe heat is very useful as both the hub and the spindle will heat up together. Everything has to be very rigid, any flex and you will not get any real force on the taper, and I believe that such a set up is preferable to hydraulic presses as you don't get the shock that a hammer gives.Alec Link to comment Share on other sites More sharing options...

Nut slighthy loose, slow short drive (note slow not as Chatters thought) and problem usually sorted.I've never had to do it myself so cannot vouch for it but I was advised it worked most of the time with no adverse problems.Ted Link to comment Share on other sites More sharing options...
DJB_Harvey Posted July 3, 2012 Share Posted July 3, 2012 Be very wary of anything but the correct tool for removing the flanges .. Many are ruined by incorrect methods no matter how well thought out . Also heating the stub axle is a bad idea as it can have a detrimental effect on an already known weak point . Remember correct overhaul of these hubs is a major safety issue with these cars especially as the parts now are approaching 50 years old .Buy exchange hubs from a reputable dealer or send them to me and I'll remove the flanges properly !
