Radial bearings for the head

[dan-uk]

Hey guys, just rebuilding the 766 head and spotted that the manual indicates two different sizes of radial bearings for the head.  Looking at them, they are indeed different brands, but are both labelled 6800Z (10x19x5).

Is the one labelled T3 200 on the outer ring the inner radial bearing

Thanks

The radial bearings should be the same. Same dimensions, same part number (108-105). The thrust bearing races have different inside diameters.

Thanks Danny.

It did come as a bit of a surprise to me until I saw the part no was the same 

I think the difference is just the snap finish on the seals (as attached).
