Check your rims for cracks.

Post by UCKeith » Sat Oct 13, 2018 4:03 pm

Check you rims. I found this yesterday. The small cracks are on my sidecar and front wheel. The really big one is on my old pusher that I replaced 2 yrs ago for another reason. When I found the small cracks on the sidecar I went out to the shed to get the old pusher to swap out the rims. But that is when I found that it was cracked wide open. All the rims that are cracked are 2013 and 2012 rims.

Thanks for the mention of this important safety issue.

It's cold comfort knowing that monitoring for cracks is made a bit easier with black wheels.

Here in Germany you will not get a rig legally registrated with alloy rims on spoked wheels since about 10 years in most counties except of Bavaria and Saxon . Some technical engineers don´t know that and sign for it but generally it´s not possible. BMW gave out a memo 1968 (!) where they say that on their bikes the alloy rims must be changed to steel rims in a sidecar application.
I wonder how Ural got their rigs onto German roads with the alloy rims. Most of the owners I know do not have any issues with them, but some do have.
Before the alloy rim ban I built several rigs with such wheels (most of them BMW bikes with Ural sidecar) and there was not a single problem since.

So check your rims for cracks. If the spokes are laced too firm they might occure.

Just replaced my drive wheel due to cracks (actually chunks of aluminum were missing). Gene gave me a decent price on a new wheel. I will use the rebuilt wheel as a spare drive wheel. 42000 Km, failed wheel was a 2013; strange since the other three are 2015.

I believe the some cracks may have little to do with "mileage" as I had cracks on my '15 GU spare that never was on the ground. The rim was 2013 vintage and replaced under warranty

This must be a 19" wheel issue. Neither of my rigs with 18" wheels have that problem and I've field tested them pretty well. Most of the issues go back to assembly when when the spokes are put in and grossly over tightened and are centered (as far as I know) to 2 sets of wheels from 2011 and 2013 respectively. Unfortunately, Ural seems to make things in batches so 1 mistake takes years to play out. Oddly enough all 8 alloy wheels in my garage come from those 2 periods and have not had the issue. I have more mileage than listed above on both of my rigs (whole lot more on the "11 Retro), even the one that has been basically down for the last 7 months due to non-wheel related issues. As far as what German (note NOT EU, yet) laws covering motorcycles are concerned, well, that is in the realm of excessive analness and has no or little basis in reality and most Germans are aware of that. Um, I'll just leave that with this, take a good look at BMW GS wheel and leave it there.

Yep. You´re absolutely right and I have to deal with that stupid regulations all the time. Talking about BMW GS-wheels (tubeless ones only): These rims are much stronger and explicit legal for sidecar applications. Since the Tripteq Heeler has been tested with that wheels, TUEV and government legalized that type of wheels for rigs.
When I look around in Europe, what kind of rigs have been manufactured by companies or built by owners with original wheels and "poorly made" connectors, without subframes etc, I see hardly an incident caused by the way of building. So you´re right again about your assessment of German laws covering motorcycles. I see it about the same way but I´m trapped in the system.
The EU-laws are overcoming German laws slowly. Step by step things become possible, we would have been hung for thirty years ago :mrgreen: . Not bad, but coming very slowly...

Between my 2 Urals I have 7 alloy rims, 3 of them dated 2010, 4 dated 2015. none have cracked yet. One of the original steel rims on my 07 patrol split open, and all required more attention.

Obviously there's still room for improvement, but it's still better than it used to be.

I feel for you! Kills me that the same TUEV also could not tell an early M72 from an R71, so now you all have MMZ, IMZ and even some early KMZ M72s registered as BMW R71s in Germany now. Allegedly there are more R71s now than were actually made to start with...just thrills collectors to death, not. They second guess everyone else's safety standards and testing (note the DOT and EU marks on some if not all the wheels in question.), generally going against, on motorcycles, anyone but BMW, but generally rule in favor of BMW exception requests, like the aluminum GS wheel...and continue as if no one notices. (I was on BMW RA's board of trustees when that happened, had BMW sweating bullets for a few months. . Heard that cost them a bloody fortune in, er, "donations", but that is just a rumor.) Flippin' travesty if you ask me! Glad US DOT (and oddly enough California) has basically ignored sidecars since we are such low volume in their eyes. And damn, EVERYONE uses alloy rims on bikes, a lot with spokes! Vent over...

And you all had me worried, so went out and checked my 103K Ural's 2011 and 2013 wheels very carefully and all 4 are just fine and dandy.
