Steering head bearing.

[Mosin]

I am in the process of replacing my very old and worn out ball bearings with a nice new set of taper roller bearing from SRM.

When I come to slide the lower inner bearing cage down over the tube on the bottom yoke, I notice that it does not slide right to the bottom. This is because there is a slightly raised section of 6mm or so at the bottom of the tube and the bearing cage sits up against it. I am sure that when I removed the original bearing it slid right to the bottom over the top of this raised bit. Is this correct?

Hi Mosin,
Try the other bearing, they have different size bores

Thanks John,

I had just come to this realisation myself. But not before completely destroying the new bearing as I was trying to remove it to swap them. 
It would have been nice if SRM or Haynes had taken the time to mention that they were slightly different as they look identical to the naked eye. Especially as SRM send the bearings out with fitting instructions which doesn't bother to mention it either. Grrrrrr.

Worth asking for a replacement.

Hi guys, this is exactly the info I needed and saves me posting the question again.

No I know there’s a taper bearing alternative, could you please post part no. or size. (It’s for an A10)

Cheers Craig

Or if anyone knows the bearing number (not SRM part number) that could be very handy.

Cheers

I have been in touch with SRM this morning and they are sending me out a replacement bearing FOC. This is absolutely excellent service because at the end of the day, it was me who destroyed the original. Fair play to SRM.

They have always been great with me. In the early days of my bike's restoration (2005ish).I learned on Gary and John quite a bit for advice. They were always generous with their time and extensive knowledge, even while guiding me through things that they otherwise sold as services.

Hi All,
Craigy, the bearings are not a standard catalog size,, they are modified

Fair play to SRM
