Your about right right with the revs/speed thought

...36mm kind of hard to find...

Just head over to your local Sears store. They have 36mm x 1/2" drive in chrome in stock.

Now I know you should not use chrome sockets with an impact but for our race car application it is the only socket that will fit inside of the driveshaft coupler we mount in place of the sprocket.

I have only broken one of them in 16 years and as always, Sears replaced it free of cost.

sorry,should have been more clear....hard to find ...in my friend(s) tool box's.  but the 1 1/2" should be available.  I did take it apart today (thanks andy)     I notice that my axle is directly in the middle of its adjustment range.....and i do hope i can move it forward enough to fit the 18T. didn't really want to add links.  when i went to the 17" wheel and a  180/55 tire,(vs.160/80) i did pick up some unwanted RPM.....just enough to bug me.  I was always looking for 6th gear as it was....now more-so. I bet the motor pulls this new gear no sweat. I have to shorten my brake stay as well.  sometime i wish i could just leave stuff alone.

I just went from a 17t to an 18t with a 40t in the rear. Same as you, my adjusters were about midway thru their range and I was able to get more than enough slack to fit the 18t without adding any links.  Hope your luck is as good.

I was running the stock length chain (110 link) with an 18/42 sprocket combo.  That was about the max combo as the adjusters were almost at the very front of the adjustment window.

I ran the same setup, required slight clearancing on the front of the adjuster slot, 18-40 should fit fine given a 110 link chain.

18 / 40 fits just fine.
