I could do with a small bearing puller

[beko1987]

Does anyone have experiences with bearing pullers?

 

I need one that could be used in a gap that's 7-10mm wide

 

This, to be precise

 

anyone know of one that will fit? Looking on ebay there's some that might do the job, but of course could be far far too big when they eventually arrive from fuck knows where land...

Bought a bearing puller to use on the CBR's wheels. Useless. Resorted to drifting them out with a socket v

[beko1987]

I cant get a socket under this though. I've used my flat crimping tool and a hammer before, but did destroy the whole armature once so reluctant to try that again!

There's a pressed-on bearing in that sort of position on Anglia half-shafts, albeit a lot bigger than what you've got there. To get them off you have to cut through the outer race, cut through most of the inner race and split the last bit with a cold chisel so you don't damage the axle. You might need to do something similar with a Dremel and small chisel.

 

If you've got some 2.5mm or thicker steel plate knocking about you could drill a hole in the middle of it, jigsaw it in half so you can slot it either side of the bearing race and stand it on top of an open vise, then maybe tap it out with a soft-faced hammer? Some wide flat bar stock might be sufficient.

[beko1987]

That's a good idea tbh, it's sort of similar to how I used my crimping tool and hammer, although the hammer destroyed the end of the armature rendering removing the bearing impossible ever again...

 

Might take a punt on this - http://www.ebay.co.uk/itm/450492-Mini-Arm-Bearing-2Legs-Puller-Car-Truck-Gear-Replacment-Tool-55X90MM-/281600566160?pt=LH_DefaultDomain_3&hash=item4190b3a390 first, then if not try your steel and vice idea, and buy a soft face hammer too...

 

They dont need cutting off tbh, on all the ones that have come off they have knocked up pretty easily

[jonny69]

Block of wood between the hammer and armature may save buying a new hammer

It would be simple enough to make something up with flat bar and threaded rod.

[beko1987]

I'd have to buy a welder though wouldn't I? And then I'd need to buy a car that needs some welding so I can justify the welder...

 

Or is that what I should do?

[Minimad5]

As already suggested:

 

Flat bar with a slot in it, so it fits below the bearing, tap two holes in it for the threaded rod .

Another piece of bar on top, but with clearance holes - lock two nuts together on top , then simply wind them in evenly (both sides)

 

The bottom bit of metal then pulls up on the threads, bringing the bearing with it.

[alf892]

2 lengths of angle iron and file a semi circle on each.

 

Place under bearing. You could make a small piece to keep in place but not really required.

 

support the angle on some blocks deep enough.......and whack the shaft down.

 

On the other hand I have a hydraulic bearing puller you could borrow but posting it would be expensive....

[Christine]

There's a guy on here that fucks about with old  hoovers ..He'll have one you could borrow  

[Station]

Just pull it off with your hand, it doesn't look that tight. Unless it's too tight for you?

[beko1987]

Oh it's very tight! And sometimes rusted on. Will splurge on a cheap ebay one tomorrow and see what happens, if not I may have to take measurements and ask someone here to knock me one up for beer and mig wire money

This style is ideal for getting bearings off motor/generator/alternator shafts, I'm assuming you mean using the 3 leg type?

[beko1987]

Have seen those kits but TBH have no idea how it works! Only went with the three leg idea as it looks simpler!

[derskine]

Like this

 

 

You clamp behind the bearing with the two silver bits, screw the silver bar to the silver bits via the threaded posts and then crank the threaded rod in the middle up and it pulls the bearing off.

Hard to explain but they're great for this kind of bearing removal.

[OwdChina]

A cheap two leg puller from Halfrauds or equiv. should get that off.

[beko1987]

That does look quite good tbh. But it's £40 vs £10 for something I'll only use occasionally...

[derskine]

They are good, but that makes sense, grinding the races is effective too though.

[beko1987]

Can only imagine how many cutting discs my shite dremel clone would destroy trying that!

[derskine]

Carbide burr in dremel might be more effective than discs, though, not entirely sure how well they work on hardened steel.

[billyboy406v6]

I used my ball joint splitter( not the scissor type) for a similar job on a chop saw motor I was repairing.

[twosmoke300]

I find those 2 and 3 leg mechanical pullers to be a four handed flimsy pain in the cock tbh . The type with the knife edge separator and 2 rods seems to work much better .
