Does anyone have an idea about the install sequence for the wheel bearings in a OEM, 17" profile laced wheel?

I pulled my bearings and noticed that one of the bearings must end up installed only partially into the bearing housing because the internal spacer is longer than the space between the bearing housing faces.

One bearing housing is 19mm deep while the other is 26mm deep

The bearings are 15mm wide and 18mm wide

Trouble is, I failed to notice which side this occurred on, and which of the bearings was on that side....

HELP!

 

On the stock wheels the manual says to seat the left bearing first,
FRONT LEFT Side Opposite Valve Stem
REAR RIGHT Valve Stem Side

Thanks, but the valve stem is centered in this optional OEM rim.

 

double post...............

 

Install the brake disc side first, on a duel disc wheel, left side first. Local dealer calls it the "primary" bearing.

 

Yes, but would that be the wider or narrower bearing on the left side?

 

Brian, help us to help you! What bike do you have and how many discs? Do you have the original wheel and does comparing the new and old help? If the old one has an offset valve you have the solution in front of you!

 

I am modifying a 2004 FLSTC to get dual front brakes.

The original wheel is 16", with off-set tube-stem, and one rotor.

I have acquired a OEM, Touring, 17", profile laced wheel to get:
1. the dual brake rotor mounting faces
2. a better selection of tires (with the 17" rim)
The valve stem is not off-set

I have noted that this new wheel is asymmetric in a couple of apparent ways:
1. the rotor faces are each different distances from the center of the hub (by 5mm)
2. the hub bore (for the wheel bearing) is different on each side (one bearing bore is 19mm deep while the other is 26mm deep)

I have noted that the wheel bearings that were in the wheel were each a different width (15mm wide and 18mm wide) and wondered which was from where, but have come to understand that the 18mm bearing belongs in the 19mm deep hub bore because the goal is to get a 1mm inset of the bearing in the hub bore.

BUT I now have determined that the bearings are the least of my worries. This asymmetrical hub is going to create problems with rotor/caliper location.

If I use spacers to center the wheel between the forks, the rotors will not be the same distances from the fork (which determines the caliper location).

If I locate the wheel so that the rotors are centered in the calipers, the wheel will not be centered between the forks. This can't be right!?!?

 

A little progress then! I think a trip to a local dealer to study a touring bike may be in order, perhaps have a chat with the workshop to get to the bottom of this. Seeing a wheel correctly installed may help solve your own installation. It's a bit difficult to help any more from across the Atlantic! Best of luck and keep us posted.

 

Done that and discovered that the long side is the right side.
Now why is this asymmetry there?
