I'm in the final stages of dismantling my '55 M18S and have just removed the top steering yoke. I was a little surprised to find that the two bearing tracks that are in the frame were a very loose fit... like a pound of sausages up the Blackwall Tunnel!!
From my experience with my older Triumphs that use loose ball bearings in the steering head I had expected to have to tap the bearing tracks out of the frame. Is that correct or has someone put incorrect bearings in at some point in the past?

Re: Head race fit
I believe they are correct and called floating cups.

Re: Head race fit
Hi
The bearing races are located by their spherical, (torroidal actually), surfaces and as such are not a tight fit into the frame, mine could be lifted out and replaced with a finger only. That said the difference in OD of the race to ID of the headstock was only a few thou.
Regards Mick

I probably exaggerated the looseness just a little.Mick D wrote:Hi
