Question on gear ratio
« on: June 20, 2015, 07:34:42 pm »
Hey guys i have a questions, i am converting my racing mowers from belts to centrifugal cluthes and sprockets, i am running at the moment a 4 inch pulley on the engine and a 4 inch pulley on the bottom of my jackshaft, i am running a peerless 820 with all gears still in it with a ec lock up kit.

My question is if i install my new clutch with a 13 driver on it and if i put a 13 driver on the bottom of the jack shaft will this still be a 1 to 1 ratio like i have now. I am gearing my mowers off the top of the jackshaft.

Thanks for any information have a great weekend. Steve Sims

Yes, it will still be a 1:1 ratio.
I don't think the shift keys are going to like the shock loading provided by the centrifugal clutch though.

My ol' buddy Sims up to new tricks and Ed King is helping him!   Hope you get them lined out.
