Axle Diameters

[hobdayd]

Hi, can anyone give me an accurate diameter for the axle diameters F&R? Or bearing part numbers? Thanks, Don

This may help, I based it on a 2016 but really should not make a difference

Thanks DogDaze.


Another trick is to see what other bikes a p/n fits. It looks like the same wheel bearings are used across much of the Yamaha line:

If you can pull the OEM bearings, and read the number off them.
Head down to your local bearing/transmission shop, and get them dirt cheap, and slightly better quality.
That said, the OEM items hold up well, all things considered.

I should explain...I want to buy some bar to slide the bearings over to use a tyre bar on so I can change my own tyres. I know that they are nominally 22mm but 22.00 or 22.10 or 21.90?

oh ok. nevermind then! ::025::

Based on the picture from Checkswrecks.
I am pretty sure it is 22mm inside and 37 mm outside (22=ø) (Z8=type of sealing) (37=Ø) 22Z837

And H7 ISO tolerance, that is -0 mm and + 0,021 mm

It's a 22mm bearing as you already know. If you can buy a 22mm round bar, you should be all set. If not, and the rod fits tight, it will only take a couple of thousands taken off the rod. Takes maybe 30 minutes manually with emory cloth. Here in USA, it's darn near impossible to buy metric round bar, so I bought a 3/4" bar and wrapped .005" brass shimstock around it to build it up to 22mm.

 

[hobdayd]

Ok, I will try 22mm bar and let you know how I get on....

The I.D. on all bearings is 22MM. The O.D. is different on the three rear bearings, but for what you want, 22MM is the number.
