Ural Alternator

On Friday, I pulled the Ural alternator after noting the position of the slotted bolts. I could still see the punch marks I made when I overhauled the engine. The slots are used to set the gear lash between the alternator drive and the cam timing gear. After removing the drive from the alternator, I tried to measure any play. I could feel a very slight amount when putting pressure on the cush drive but it wasn't enough to even try and measure. Just to make sure, I disassembled the drive by pulling the drive gear then pushing out the shaft. There was an internal snap ring holding the bearings in place. This was easily removed followed by the bearings. The bearings looked good, very smooth movement. I removed the dust cover from one side of the bearings and there was still plenty of grease.

After reassembling the drive, mounting the alternator to the drive, and reinstalling the unit, I went for a short ride. I could still hear the whine but I guess it must be normal. No pictures as everything was good. Total time was maybe half an hour.

Last Spring, SueL had mentioned that she wanted a sidecar ride. Saturday was a great day for riding. Clear and sunny. We went around the Chena Ridge-Chena Pump loop and the Fall colors were wonderful. She mentioned that the view from the sidecar was much better than when riding pillion. Of course I pushed the concept that they needed a sidecar rig. And I know for a fact that the BMW they have would pull a sidecar around just fine but I'd look for something more comfortable than a Cozy. (They had picked up my '83 R100RT last Spring) I nabbed this photo from her FB feed as I forgot to take one.

Well done re the ride for SueL, you're a good ambassador for sidecaring. As to the work done on the alternator...were you feeling bored? ;) The darn things have always had a whining noise, in fact, it comforts me to hear it....if it stops, then I wonder.

I had noticed the slight bit of play when I had the engine apart. I was just wondering if it had gotten any worse.

Creating sidecar owners one free ride at a time. Good job.

I try to suck others into the insanity known as "Ural".

You have cause me considerable stress. Now she wants me to get a sidecar rig instead of a boat. Not sure I make enough for either let alone both. Bad Richard! :-)
