Paul, if you use the search function “T6 steering head bearings” you will see my solution and measurements. It works well.
Thanks Bert, I've already ordered some bearings but having read your article....I've ordered the same as you!  :)

I'm pleased to report that my headstock bearing removal tool worked rather well.  Not my design, but I did make it  :wink:

Piece of hard steel; small diameter to clear the outer shell, while the large diameter is thin enough to fit under outer shell but not too wide to foul the headstock sides:



Slice it into 6 pizza segments and then insert four of them.  Using the same drill that you used to drill the initial hole (1/2" in my case), centre and straighten the four pieces and hold it together with a jubilee clip.  If you've got the sizes just right, you might have to tap the drill into place and then use the jubilee clip to straighten the pizza segments.  It should be rock solid before the next step. 



From below, tap it out.  Mine came out quite easily; top and bottom.

Paul,
         If the outer tracks are worn to the point of not being reusable, a method I have found that is very effective for their removal is to lay a short run of arc weld on the inside - as the weld cools, the track contracts enough to slacken it and get it moving.

Regards,
              Eddie.

Thanks Doug for that chart...I assume that is at the front of the parts book....I'm wondering what else I'm missing  :frown:

Thanks Eddie, I'd found that one on the BearingBoys site and will probably use that.  I found an old article in the New Conrod where someone had used angular ball bearings but as the nearest ID is 25mm, they had to turn down the sleeve that the bearing fits to.  Your taper roller with an ID of 26.99 (1 1/16") is spot on, so I'll go with that.

While we're talking bearings, as I was missing one of the races for the clutch bearing, I converted it to a sintered bronze thrust bearing and gave the bike a ride yesterday.  Although it works, the "drag" of the large surface area of the bearing gives rise to a rather weird feeling; it feels like a brake is being applied and the quicker you release the clutch, the better.  I'm still finding the optimum adjustment for it (on the cable adjuster) but I'd like to get back to a roller/ball bearing if possible.  Going to take a closer look at some of these needle roller thrust bearings and see if I can make one fit...

...now off to garage to make a tool to remove these headstock outer races.

Paul,
         Have a look at 'Simply Bearings' website - they list a taper roller bearing that is 50.29 O.D. x 26.99 I.D. x 14.73 high - that should fit the S6 with just a stepped sleeve to make the O.D. and height correct.

  Regards,
                Eddie.

The ones I bought for my A31 decades ago were 45 degree. Would think the 350 EW was the same.
