Triple clamp help

New to the forum….. I recently picked up an early 80's 250CR to restore. I am in the process of disassembling the bike and need some guidance. I am taking the triple clamp apart to have it re-powder coated and I am running into problems with the bottom of the clamp and stem. What is the best way to remove the stem and lower bearings from the bottom clamp. I have had it in a 20 ton press and have not been able to budge the stem from the clamp, I have removed the circlip. I haven’t gotten too aggressive with it as not to bend the bottom of the clamp. Suggestions, thoughts ?

Thanks,
Mike

It should come out pretty easily with a press. Remember to push down on the top of the stem so that it exits out the bottom of the lower clamp. The bearing will slide off as this is being done. Put some support under the clamp next to the stem area to prevent flexing.

migz,
Just my $.02 worth.

If your just powdering the stock clamp, leave the stem attached. Bust the old lower bearing off and let the sandblaster/powdercoater tape the stem assembly up before they do their work. Put new race and bearing set in once they are done and you'd be good to go.

I needed just the stem for my project and the dang thing had to be cut out the lower clamp. Thats after heat, a big ball peen and subsequent press.

I had the same problem and did the same fix. I just let the Powdercoater Tape it off after removing the Circlip and washer. Mine didn't want to move either.

mee too

i left mine on and got the coater to tape it up worked spot on

+1 above, just leave the stem in.
I was able to drive the lower bearing off with a long tapered punch and hammer by holding the punch at a 60 deg. angle to the stem centerline. Hit one side then the other.
There is a slpit puller adaptor for this type of bearing. It has a knife edge on the ID. You tighten the halves of this device under the bearing then attach a puller to it.
The bearings for an 86 are Timken L44600LA and race L44610. The bearing has the grease seal on it. Very common as it fits a trailer axle as well.
Don't forget to put the spacer washer under the new lower bearing. You can easely drive the new bearing on with a pc of pipe. Be sure it is seated by tapping on inner race with long punch and hammer.

My local bearing house had the bearings no problem but those Grease seals no way....
