Then I could just trim the marked part off.

Test fit with the aluminum. No key at this point.

It took a puller to get it off. I knew I was shimmed correctly because the inside of the pulley was flush with the shoulder on the crankshaft.

The brass came in different thicknesses. I measured it at .0025, same as the can. Again I traced it and trimmed as needed. This time I made room for the key. It went on relatively easy, the shims didn’t need anything to slide on and stay where they needed.

The old key was buggered a bit but since my package from Old Britts showed up today with a new key I was golden. The new key fit much better. Without tightening it down it was much tighter. Just the tiniest little movement. I reassembled and will try it out tomorrow. I don’t expect any issues.

Thanks for all the suggestions and the banter.

One less thing to worry about.

good photos too!
 
I knew you were a mechanic and no mere parts replacer. Good show. I hope any remaining run-in issues are minor because you've earned this bike the hard way from where I sit....Need a perilous road vid.
 
looks good. Maybe check the pulley run out with a dial gauge just to see if there's any wobble due to whatever dressing was done to the shaft taper before you acquired it. I'm not sure what the tolerance would be, but it would be good to find out how close to perfect the shimmed pulley is spinning...

I’ll do that the next time I’m in there. I know there’s some people who don’t like the belt drives but you can be inside the primary in less than five minutes. With a chain you’re still waiting for the oil to drain out.

I would never call myself a mechanic. More like an intrepid tinkerer.

I'm totally interested in belt drive primary, but I don't have any experience with them. What's not to like? It seems like a better system to me... (not looking to open that can of worms...) I just wonder how much run out they tolerate, and certainly in your case, the potential is there for greater run out, so I felt the need to mention it. At some point I'd like to convert to a belt drive primary myself, but I have other real life issues that are piling up, demanding the money in my pocket. I'm lucky that my commando only needs to be fueled up to enjoy it, but I still have a list of things to change. A belt drive is near the top of that list. Well done
 
Steve Maney in the UK makes one of the better belt drive systems around. I have had experience with them in four bikes, I have two, one 30 mm in the Roadster and one 40 mm in the race bike.
Belts are off the shelf Optibelt OMEGA ,the system is lighter weight overall than standard set up and no need for oil in the chaincase which usually means one less oil leak to deal with !
I like them.
Regards Mike

He only has a few left. So if you want more you better not wait.
 
I’ve run the Maney belt too and agree it’s a well made quality bit if kit.

Then again, I actually ran a Norvil kit for longer, and that never gave any trouble at all.

But my favourite has to be the cNw belt I’ve just fitted.
 
Bob Newby is worth an honorable mention as well.
Spoilt for choice we are.
 
I recently felt the clutch on a Newby fitted to a Commando and was kinda horrified at how heavy it was. Dunno if they’re all like that?

This because....it has coil springs, not a diaphragm.....compare original Atlas with original Commando....

As you continue pulling the lever with coil springs you are continuing to compress them, with a diaphragm the spring flips and the load required to hold it reduces......

Bob makes a nice clutch that many people like. I have one of his pulleys, very well made. But I have a Norman White clutch drum and I like that. It is smaller and lighter than Steve Maney's Clutch because it doesn't use Commando plates and centre, but unlike Bob Newby's it also has a diaphragm spring.

For a race bike I would only consider a belt drive. For a road bike I would just work on keeping oil in the primary and save my money for other more important stuff!

The key is in the words......'you won't notice the difference when riding!'

Keep servicing the real life issues :)

Ok so I got off the couch and checked. Mine is on an ES2, I don’t know whether the springs are heavier on a Commando version. It is a little heavy on initial movement but has quite a short action (lever stops well clear of the grip) and something pops over centre so that it is easy to hold fully in.
 
Looks good swoosh. That's how we've all become mechanics - confronting problems head-on. There's a real satisfaction working through a tough issue and coming out the other end. Like they say, the proof is in the pudding.

I could bring a dial indicator over to check runout.

You could but a dial indicator was one of the first tools I got. The one I have is a good 25 years old.

I’m not too worried about run out.
 
Which reminds me that I need to go run mine down because sooner or later...
It is a real pain to search for something you need when you need it then. Dave...you are a good influence to help control my bad habits.
