Topic: Early ARD pulleys needed for the triple (solved)

[Don R]

  The title says it all, RC jr. needs the ARD pulleys and belts for the triple to reverse engineer them. If no one has a parts mag, I'll offer to loan my mag.

Thanks for your help Don.

Don, if you have the pulleys, just measure them and find off-the-shelf parts to fit. McMaster is a good resource.

Also, the way the ARD pulley attaches to the end of the crankshaft is problematic, and if I was going to re-engineer anything on the ARD it would be that.

Don did I understand from the recent FB post that Russ had gotten access to the correct ARD drive parts via a thread here on the forum? I vaguely remember an entire thread here on them, but since the one I have is buried in some box for a project 'somewhere down the road' I never followed up on the important stuff.

 Yes, I believe someone got them the part numbers for the common industrial pulleys used on them.  They are covered now. McMaster Carr or Grainger can supply them. I wondered if that information is posted here somewhere.
 I think a lot of ARD's get pulled off of old engines and the crank adapter gets left behind. My CD version of the ARD has the crankshaft end but most of them that I see for sale are missing that part.

 It would be awesome to make a FAQ on the ARD information so it's all in one place.
