ebay hub puller

[Palmer 221]

Hey all,

bought me on of these the other day.


http://www.ebay.co.uk/itm/2524318746...%3AMEBIDX%3AIT



Iv got one one there hydraulic things on my gear puller, I will admit I do prefer the feedback you get with a breaker bar, but this thing made removing the drum like opening a jar. So I would recommend.
however I do wish i came in a blow moulded box rather then the Avon flight case

Cant win them all.

Estate fans! any recommendations on sourcing replacement bearings??




I will email my Haribo supplier but knowledge is king

Cheers Palmer

That looks like a good piece of kit.Any good bearing supplies shop should be able to get hold of those bearings,just quote the number on both parts.

This is described as a 10 ton puller. Is this more than can be achieved with a non hydraulic puller?

Palmer;

WOW! That is the most impressive Drum Puller I've seen to make the irresistible force necessary for some stubborn Drums on a Volvo! (No!, I am not the one offering it, but the price seems reasonable even, for what one is getting: The ability to persevere against even the most stubborn Brake Drum!)

When using it, be absolutely certain you put the Drum Nut back on loosely (castellations IN), to reinforce the halfshaft, lest that irresistible force turn the end of your Axle shaft into a metal Portobello! ...in looking at the listing, it states: "Hydraulic"...so I had to think about it for a moment...and here is what I came up with...it works by means of the (almost miraculous) principle of Hydraulic Force Multiplication:

...and to retract it, I would start by unscrewing the input piston...the unit might have a self-retracting provision...I've drawn in (orange) a retractor (compression) spring which might be in there...of course, on the other hand, it could also be a tension spring on the other side of output piston. If it doesn't self-retract, I'd try backing off the input piston, and pushing the output piston back in...worst case, squeezing it together in a press...

I advise you work carefully and methodically when wielding the "Power of Excalibur"!

Good Hunting!

PS. Seeing as this is I expect one of the most (if not THE most) powerful Drum Puller in existence, I request your permission to include and republish your pictures of it on the SW-EM site.

PPS. As far as that case vs a blow moulded case (with a "live hinge", right up until it dies). I'd prefer it in a nice case...you wouldn't put Excalibur into Mc Donalds Styrofoam container would you?

[Palmer 221]

wow,amazing response. I am impressed with your x-ray capabilities, and of course I am an advacate of sharing knowledge!!

The piston was smaller then the diamiter of the half shaft so i didn't put the castle nut back on. but sounds like good practice!

Thanks for the bearing advice, looks like brookhouse has the bearings so putting an order in later.

I don't know what bolt is used on the conventional puller but I think the clamping force off a tensile M12 bolt is around 7 tone?

I still don't like the case

[grahamwatson]

Can anyone confirm the 7 tons? I still have a recalcitrant drum so an extra 3 tons (assuming the 10 ton is also accurate) is certainly something I would be interested in at this price.

And all those extra slots in the puller face would mean I could get some more heat closer to the stiction interface.

Graham;

It's the temp delta that's important here! I can't speak to the numbers, but on the coldest day (or augmented by extreme cooling by liquid Nitrogen from an industrial gasses supplier), I'd get the Hub toasty warm with a oxy-acetylene gastorch, then quickly install Palmer's PoMaIF (Puller of Magic and Irresistible Force) and DON"T FORGET that Drum Nut!!... and have at it...I'd bet a pint something will yield...hopefully the stretched joint of desire!

Good Hunting!

PS. I still like that case better!

I just ordered what was claimed by the seller to be the last of the ebay pullers--but I suppose that every one ordered was the last one. I have no immediate use for it, but when I inevitably do require one, it would be nice to just go to the toolbox and pull it out. Much better than sweating and cursing for two days. I am having it delivered to my pal Phil Singher, Volvo Amazon expert and mechanic extraordinaire.

eBay page says 2 available 64 sold so they are popular. Is there a makers name on them anywhere? That might make them easier to find elsewhere.
