Re: Ural Dnepr Flywheel adaptation (pics)

I had to move the engine to the right to fulfill the critical dimension of matching up the drive shaft giubo to the drive shaft. This involved some drastic rigidity compromising frame cutting so I could retain sidecar capability. The Ural frame lower cradles are approx 1/4" thick round tube. I'm goi...

Re: Ural Dnepr Flywheel adaptation (pics)

A v50 gearbox? Funny story about this Ural drivetrain. When viewed from the rear, the 4 forward gears spin the driveshaft clockwise. So something in the kardan is different on Urals compared to Guzzis. But before this project started I made sure I wouldn't have 4 reverse gears!!!

Re: Diesel Bike Diary

I plan on making my adapter plate from a thick piece of aluminum. 2 inches thick (.05 meters). and one square foot area (.09 meters^2). Im looking at about $250 USD. What's your idea for an adapter plate?

Re: Ural Dnepr Flywheel adaptation (pics)

Thanks for the info. Im working with an Ural 650. But I seem to have the same need for low profile bolt heads. Mine is a 2001 Ural Deco which broke its crankshaft at 3000km!
