Is there a Left or Right side on Snowflake

Read this in my repro Riders Manual or the Clymer while doing my dual brake upgrade. It says to be sure to install front wheel in the proper orientation. There are no markings on the wheel to indicate a right or wrong side as to the way the wheel should roll. Now there are casting marks with part numbers and other info on one side only. The wheel is installed with those casting marks on the left side. Seems to spin fine by me with just a very slight drag from the pads/calipers. I don't feel the Snowflake is installed backwards. Just checking.

Maybe it is referring to the obvious orientation if it was a single caliper that originally came on my '78. I believe the complete fork/dual brake/wheel setup I installed to be from an '82.

Thanks Dave

My 81 has had the wheel both ways with no problems.

+1. Tyres and keeping the same discs with the same pads.

The wheels are stamped with an "R". I have no idea why, except that the people who made them had no experience with BMWs.

I'm running Dunlop K70's front and rear and they are not directional. But I do see your point and that would be very important. And even being non-directional I still keep the tires rolling the same as they set in from new. That I would have certainly noticed and did keep it the same. You never know what the other person could have missed. Never hurts to question the obvious.

Tire direction. Also keeping the rotors matched to the calipers?

Tried the multi quote and lost the entire message. Maybe it has something to do with spoke wheels. I don't know.

Very possible. May have nothing to do with spacing L to R at all. Bike is setup ready to ride, I'm just not a negative (below -0 F) temp rider. It'll be warm enough before long.

Look at the valve stem on the rear snowflake when it is at the bottom. The stem is to the front of a "main" spoke. I orient my front wheel the same. I don't know if it really makes a difference or not, but that's how I do it.

Yep, the spoke wheel hoops are indeed directional believe it or not. They have a little arrow stamped into the inner tire seating area. I have a picture of one somewhere.


Edit: Found it. Here's a Weinmann from my r75/5

What's funny about this is that the rear Snowflake has an arrow cast into it
to show direction of rotation, when you can only put the rear on one way!

That's interesting. I wonder if the arrow is there so the bearings always spin the same. The rear is obvious as to how it goes on.

I dunno, i don't know if it makes a difference in how they're laced on the spokes or what? I put it back together correctly when I got new spokes...I forget where I learned about that, probably Hucky.

I put my Lester front wheel (dual disk) on backwards--there is an internal spacer sleeve in the bearings that if you get the wheel on wrong, it won't line things up and the wheel binds. As I am a lazy sort, I just pulled the spacer out of one side and put it in the other and it was all better.
