I've just welded 16mm reo rod into the inside of the steering head bearing inner cones to get them out. is there an easy way or a bearing puller I don't know about?

A couple of nights ago I ground a cup head bolt down to remove a wheel bearing. Once again, is there a puller I don't know about?

The  steering head nut, 8*4mm pins. Is there any easy way before I make something?

Zanes...love the challenge...absolutely love the challenge.

Keyboard breathylock is off.. sorry.

A bead of weld along the inside of the bearing race should be enough to shrink it sufficiently to have it fall out, even out of the alloy frame.

You can tap the steering head bearings out from the other end with a drift. Use a steel drift because there's only a small lip of bearing cone to get the edge of the drift onto. Anything softer will mash its edge. Keep an eye on the bearing alignment and work your way around as you tap so it comes out straight.
 
10 mins with a heatgun on the headstock usually makes it easier to remove and replace with new while its still hot.

Heatgun and rawlbolt is my usual method for wheel bearing removal, should be lots of opinions on here if you use the search feature.

Hi Greg

I have accumulated an assortment of various of these bearing tools over the years, I especially like the wheel bearing removal assortment, the blind bearing puller set is pretty good, there is also a set for the head stock bearings, etc.

Not the worlds best quality, but reasonably priced and work fairly well. If you spend more money you can get better, but they seem to do the job and last fairly well

Paul,

Only just found your response, and have book marked the page. (thankyou) I've had a lot happening the last couple of months..

So far the only bearings i'm having problems with are the swing arm needle rollers. I can pick the old needles and cage out easy enough, and was looking at modifying a collet chuck type tool to expand inside the drawn cup to allow me to pull, or push, it out. I'm not sure yet if the lip of the cup is strong enough.

I can't get a drift in behind them from the other side. I also haven't tried a run of weld inside the drawn cup, or welding a nut inside the cup so I can punch, or press it out from the other side.

I'm not really into re-inventing the wheel if I don't have to....

Regards

Greg



 
Those blind bearing removal tools look like glorified rawlbolts to me Paul. ;)
 
Hi there
I'm facing the same challenge with no bearing lip or inside edge to use a drift to extract.
Please advise the best way to extract. Imp concerned heat may damage powder coating on frame
