I feel like I should already know this, but how is the belt deflection set on the 67 Oly with the original 3-pin secondary? Yesterday I was taking her for a test ride and noticed that when idling, the belt was REALLY loose. Like there was 3" of deflection. So much that it looks like the belt is hitting the belt guard and eroding a groove in it. I don't think the chain case position is very adjustable?? Anyone have a shop manual for it?
Thanks for any help.

Hey Mark, I don't have a specific manual for that sled. But if you just loosen the case u bolt and slide the case forward after also loosening the long stabilizer bolt, you should easily get rid of some of that slack. I don't think it has to be perfect, but a little at a time you should find the sweet spot. As long as you can idle without walking away and the belt isn't pulled into the secondary while idle.

Thanks Vince! I'll give that a try. I wonder what the actual distance between the sheaves specification is?
I hope I can make the adjustment without removing the hood, LOL. I don't really want to drill out those rivets again.

I'm guessing that it will be the same (or close) to what the 1970 models show. @ 1/2" offset, should be about 1 7/8" between pullies. I like to just use two 5/16" nuts on either side of the pulley to maintain the 1/2" distance (the nut it 1/2" O/D between the flat sides)  |

Cool Vince, thanks for the info! I'll shoot for the 1 7/8" distance and see how that goes.
