Hi;
Does anyone have two 9030 bearings for sale? Or post the dimensions so I can obtain a modern replacement(Od Id and width).
Thank you;
Bill

Hi Bill,

as far as I know the 9030 Bearing was only used for the early cam side main bearing 47mm x 20mm x 14m (6204) ... later they changed the cam side shaft to 25mm and used the 47mm x 25mm x 12mm (6005) bearing.

On the sprocket side they were using 52mm x 25mm x 15mm (6205) for ball bearings and later a 62mm x 30mm x 20mm (22206) -- spherical roller bearings

all can be bought in any technical store ....

hope this helps

Ralf
