Steering head bearing replacement Tenere XTZ660
 

I am replacing top and bottom, I plan to use aftermarket bearings (complete set less than one OEM bearing from Yamaha and I am pretty sure its the same bearing) , but I am trying to figure out if there is a seal on the lower race. On the parts list I have it just shows the bearing. Has anyone done this and figured out if there is a seal what part number it is ?

I am sure I have seen a reference to this somewhere on the forum but cant find this now

Thanks
Scott

I believe the KOYO 32005JR (upper) 32006JR (lower) come with a built in rubber seal, but not totally sure.

All the bearing reference numbers that I have for the headraces are below:

Upper: I/D 25mm x O/D 47mm x W 15mm (SKF 32005XQ) (Koyo 32005X or JR) (Timken 52005X) (FAG 52005X)

Lower: I/D 30mm x O/D 55mm x W 17mm (SKF 32006XQ) (Koyo 32006X or JR) (Timken 52006X) (FAG 52006X)

Yamaha make motor bikes & a few lesser things...
Not bearings or seals... they buy them just like you can...

What ever you choose make sure you use plenty of grease especially in the bottom one as the heat from the oil in the frame tank dries them pretty quickly..
