Guys have a question I have a cub 105 or 6 but my question is the clutch what do I need to change out to pull in a stock class with a 4000 rpm limit. Will my 3 pin work with a new disc and spring and throw out bearing. And put a pillar bearing in the shaft or just go ahead an drill my driver and make it a six pin I have acesse to mills and lathes so that's no problem just need input on what to do I can do the work. And the stock drive shaft should I replace that also. Thanks in advance.

Welcome to GT Talk.

We have a few Cub pullers here who should be along in a little while.

Hello there and welcome. I would put a heavier clutch spring in it (a red spring from either Midwest super cub or any of the tractor pulling vendors) You should also change your gearing because with cubs being a 3 speed you only have access to one pulling gear which would be your second gear. You also might to find a shifter lock of some sort either a bungee cord or a home built shifter lock so it doesn't jump out of gear.

Thanks for your input. Which gearing the ring and pinion or the other gear sets. Is 3rd to high to pull with.

I would see what you have before going to far  We used to pull a 10hp on 26's using stock 1st and 2nd.  For the clutch we used chevy valve springs over the stock spring and put piano rosin on the disk (just a little other wise it will stick) As for the pillar bearing unless your going to run more hp and rpm's I wouldn't do it

Did you just put the valve spring over top of the stock spring or stack up the springs I had thought about that. Also the valve springs that I bought for my 10 kohler from Midwest cub is Chevy stock springs with a diffrent retainer for them.im pretty sure I haven't rated them yet but I am just to see what I have.

I believe the stock 3rd gear is a 26 tooth but im not sure. The only stock gear you'd be able to use is 2nd which is a 19 tooth. I would check with your local clubs rules before you modify anything. What you do to your engine determines what you need to do to your drive line and rear end. If you look at the back of Midwest super cubs book on the gearing, it should give you a good idea of what to use gear wise.
