Subject: Wheel Bearing Specifications


Hi folks

Here's the bearing specs from the MPS catalog in the UK.

Dimensions: 	Inside Diameter, Outside Diameter, Width

FRONT		6203-2RS	17x40x12 	GBP 7 / DEM 19
REAR LEFT	6303-2RS	17x47x14	GBP 9 / DEM 25
REAR RIGHT	6203-2RS
SPROCKET	6204-2RS	20x47x14	GBP 8 / DEM 22

The ones shown in the catalog are Koyo bearings, we can also get cheaper
Korean ones for GBP 4,50 / DEM 12,50.

The MPS phone # is + 44 1626 835835 fax +44 1626 836666 but I don't
suppose the UK is any cheaper than Germany.

I haven't changed the @ ones yet but on other bikes I haven't needed any
special tools. Previously I've changed them by first breaking up the
cage on one of the bearings and removing the balls and the center, this
gives access to the back of the other bearing and it can be hammered
out. After this I put the balls+center back in the first bearing, spaced
the balls out with bits of paper to make sure the center is gripped and
then hammered this out from the back.

Regards, Phil

PS Welcome back from Italy. I went to Scotland for the weekend so the
last thing I want to hear about is how sunny it is in Greece ! :-)
