Got no such magical device. Used an allen wrench to pry it out. It looked fine - no flat spots or signs of wear. The races refused to come out. I put the new bearing in just for G.P. and will put the pivot arm, etc. back in place tomorrow after work. Then I will start her up and find out if she makes the noise.
Question - does the bolt sticking out from the pivot arm have any function that may cause it be adjusted? Clymer's is silent on that.

I was able to get the tranny side clutch parts put back on. Have free play at the handlebar clutch handle. No change in the noise - when the clutch is engaged, noise like a Ducati around 3,000 - 3,500 rpm. No rattling when clutch handle is pulled in. No noise when clutch is engaged and engine speed is at idle or 4,000 and higher. Ain't never heard this before, definitely coming from the clutch area.

Took the old gal to a bike shop in OKC that works on airheads. Was told an input gear blew apart and spewed forth metal shavings throughout the tranny. I am now looking for a good used tranny. Else the bike goes to the junk yard.

Ah well, at least you now know what went wrong. And you live in the US of A where used Airhead parts seem to be readily available. Perhaps a Wanted to Buy ad in the Airheads section over at ADV will yield something. Maybe somebody here has an excess of gearboxes. Best of luck.

Thanks! I have asked the shop for an estimate to clean up the tranny. Have found a few on eBay for around $500.

This should be a lesson to all airhead owners. If you rely on your bike, have a good, tested, spare transmission sitting on the shelf. You WILL need it.

Hey Manfred, I'm in Oklahoma too, north of the city in Crescent. If you get serious about the 'junk yard' give me a call, I'll save you a trip and come and pick it up - Rod

Will do. You are 180 miles north and west of me.
