Who can press steering stems for me?

Is there an appreciable weight difference between the two? I bet not.
I dont't think modifying the stem to accept bearings is a particularly good idea, why not just buy some new bearings that will just work?

No such bearing is made is what I believe.

theres no gap between the inner race & the yoke to get a puller in... if yer pull on the bearing cage it will all come to bits
leaveing the inner race still on the stem.. Have to press the stem out...end of story..

Alloy stem.... the CR uses titanium... looks like alloy..

whats the ID & OD of the bearings you require for the conversion ?

Going back a few years but once had a kx250 set modified to fit a tt600 wanted the disc and usd forks on it. Simply had engneering shop trim the over all length as the stem was to long did have the cut more thread tho then a small amount of machining to get the right bearings to fit. Went that way as our 20 ton press wouldn't get the stem out of the yoke.

I had wondered if it could be turned down to suit the bearings with it still on the crown. I would have thought that would be impossible to do.

Cant think of the name of the place but it was in Olive road penrose bout half way down next to firestone western side. Cost stuff all and was the easyest way round the problem.

I have replaced countless steering head bearings.

I've never once had to press the stem out of the triple clamp.

Have to agree with you there even if the cage comes apart all you have to do is the place the clamp around the inner casing and press it off. Heat them right and the new one will faal back into place. Just watch the wifr isnt watchjng you using the oven as a bearing heater and dont over heat.

Use a mill to trim it down, then a live center to steady it while cutting the thread and new bearing fit on the lathe (at fairly low speed).

One I did a while back has those 45deg angular contact ones that come in 3 peices anyway, cold chisel and drift was needed to get enough separation on the bottom casing to even have a hope of getting a puller onto it. It was also a steel yoke with welded stem so pressing it out was a difficult prospect. Fucking kawasakis.

Have finally got round to getting this under way in between surgerys etc blah blah.

Even getting the axle modded so I can run the KDX front wheel.

Happy days.

Will give me a little project while I cant ride after my surgery.
