For Sale: Omega Lister Clone 6/1 "NEW".......$1800.00   Pickup Only

Matt.....Escondido Ca

Back in the days when I used to repair gearbox's I found the easiest way to get bearing off shafts was to just stick the shaft on the over head crane so i could spin the shaft then apply the oxy torch to the bearing while slowly spinning the shaft. Wor...

The slitting wheel method works a treat. For the outer race welding round the track works great but normally ball race are not a tight fit on the outer housing.

Once steel on steel has cold welded there is little chance of getting enough heat intio the...

heat the race good and hot--then stick the shaft end in ice..the rapid cooling  and contraction of the shaft should make it easyer to break the race free............

Sparweb  you can find any number of suggestions on the web especially in the practical machinist
 Had this been the outer race you could have run a weld bead around the inside when it cooled it would have contracted I used to rebuild a lot of heavy eq...

Oh yeah I buy WD40 by the 6-pack.  It was liberally applied while pulling, to some effect.  Just not enough, that's all.
I'm definitely going to pick up some Never-seize as you suggested before.
Thanks again.

Spar another hot tip, a can of good penetrating oil like PB blaster can take out a lot of the cussing fussing when trying to unstick things

OK that worked.  I made 2 cuts with the dremel , using the 1/16" cutter disk.  Cut as deep as I dared, and whacked it with the cold chisel.  No effect the first try, so I cut a little bit deeper, then hit it again and it cracked.  I nicked the ...

that all depends on what you want to do with the juice and at what speed your alternator will spin at ,
my vertical mills rotate slowly .
i opted for single phase initially now i do two phase.

Yep, a cut on each side with a cutting wheel on a die grinder, then whack it, don't heat it you want it to stay hard so it'll shatter. QED.
I'm surprised you didn't polish that shaft before you tried to pull it.

Done this lots of times. Use a dremel like rotary tool with cut off disks. One cut and a cold chisel into the cut will crack it loose. An old flat tip screwdriver hammered into the cut slot will do the same. Add some oil once it's cracked loose and wor...

heat one spot on the race with an acetylene torch till yellow hot and the race will come off easy

Yuasa Endurance (AGM's) 2*12v 100Ah for 24v, ex-telecom backup, bought 2nd hand about 4-5 years ago, used daily, still going strong (though I try not to go below 80%).

looking for something bigger now, and sometimes struggle to get them fully equalised...

more than likely the race has stuck only because of oxidation build up like mentioned cut and split the race  use 2 cuts though to make things easier
 be sure to emery the shaft clean before installing new bearing

My self I would cut it all most to the shaft with a 1/16 grinder blade. Then wedge a cold chisel in to the cut crack the last bit.

Hot tip when you get it off and cleaned up use never- seize on the shaft.  So the next time the bearing will come off wit...

 Angle grinder and thin cutting disc ? Make 2-3 cuts, so the hard race could crack when struck with 2 hammers, like cracking a nut.

 Just the heat from 2-3 cuts might also swell the race enough to tap it off.

This should have been easy.



I'm replacing the bearings on my genny.  The rotor's rear bearing came off without complaint but the front bearing got stuck half way off, pulling harder just broke the outer race.  Now I can't get the puller to c...

I don't have any Xantrex inverters at this time.  Don't really have a practical need for one at this time but would like to go 24V in the future so a 24V Prosine 3.0 would be cost effective.  These are about the price of a control panel. In about two w...

Thanks, I understand now. Will get hold of some steel plate and do this soon.
How much of a benefit would changing to 6 coils and 3 phase give over of 8 coils and single phase?
