extractin steering head bearings

[Deleted Member MS]

Gs 100 (92)
Winter stripdown time, but how do I get the steering head bearing outer race out of the frame ????
I presume there is a special tool available ??

As the frame is about to be powdered, I thought about heating the area around the race to watch it hopefully pop out !!

Idea anyone !!!

Thanks in advance.

never done it, but i know there is a special tool for the job.

2 other ways:

weld around the bearing faces. weld shrinks when it cools & bearing falls out.

weld a bar across the bearing & use it to beat out as normal

Just recently faced this problem myself, heat from a blow torch and a gentle tap via a cold chisel did the trick.

Bearing removal tool - and others

In the US, this guy makes some great tools. I have the bearing removal tool, it works very well, no damage to the headstock.

the neatest trick that i ever saw was watching my old man remove a bearing race from a heavy gearbox.
He ran a nice even weld around the inside of the inner race, waited about 30 seconds and just lifted it out of its housing with his gloved hand.
As the weld cools it contacts the metal around it just drops out

While its totally over the top for this it is an option where the housing is soft , ie head race in alloy frame

just thought i would share that with you

Works on the head bearings, thats how i get them out, takes less than 2 minutes.

Also works on airhead swingarm bearings .

But don't do as they say in the haynes manual, about removing the inner race off the bottom yolk, by heating it up and pulling the stem out. You'll feck the stem and bottom yolk.
Just cut the old bottom yolk bearing off.
Heat up the new bearing and drop it onto the stem.
