Replacing the Nippon Denso Alternator
< -------------------------------------------------------------->
I'd developed an oil leak from my existing ND Alternator. Based on the location of the leak (coming out through the cooling vents in the alternator itself), I determined that the source of the leak was the oil seal in the "cushion drive" adapter. Felicia Landes of Wagner's Cycle Shop was kind enough to provide me with a warantee replacement for the entire alternator assembly. So, pulling the old one out and installing the new one was a pretty easy job. Here's how I did it...

Serious thanks go out to
Rich Maund for the wonderful write-up he did on this topic. His write-up is available on the Wagner's Cycle Yahoo! Group web board. Check it out - it's a beauty!
Step 1: Assemble the Tools

The tools for this job are very basic. In fact, you could do the entire job with just the provided Ural toolkit. I've added a couple of tools to make things go a bit easier - like a ratchet wrench with an extension and an 8mm allen socket...

The dielectric grease was used when I re-installed the electrical connectors onto the new alternator.

Step 2: The Supplies

You can't install what you don't have... As stated earlier, I got the new ND alternator assembly from
Wagner's Cycle Shop. Flicka and Mike are great folks - call them up and they'll get you what you need!

Step 3: Disconnect the Negative Leg of the Battery!

Always unhook the negative leg of the battery when doing work on the electical system of a bike. For that matter, if there is any risk of shorting a circuit to ground when working on a bike, be smart - disconnect the battery. It only takes a minute - especially since I'd "flipped" the battery around so that the negative post is on the "outboard" side of the frame.
