THANKS George!  That is exactly what's there.

Sounds like either way I'm good.  If one is steel, both are steel, I might as well go with what's there.  Kinda like the idea of the bearing in there whether it helps or not.

The chain and sprockets are going, just as you mentioned.  I've seen you write that several times in various places.   Friday I'll be getting some sealer and oil to put this bad boy together!

While I'm at it, your tranny plate looks SWEET!!!!   It won't be hard to tell the stuff I fabbed up with my limited available resources, and the stuff I bought.  LOL

Dale, always grateful for advice in Michigan.  If you ever wanna know about a Wheel Horse, ask, that's my area!!   LOL

My luck never ceases to amaze me.

This 700-078 transmission I bought has an output shaft number 776421 with nine splines, as opposed to the apparently more common output shaft number 776217 with it's much finer spline setup.  You know, the one that fits the sprockets George listed and I bought along with the transmission.

To change the output shaft, assuming this is a straight swap, will cost over $80 with shipping.  That's over half what I paid for the dern thing.

Before I just go ordering up sprockets or shafts willy nilly hoping to get something that will fit, does anyone know the sprocket part numbers that will fit this beast????  Are there any outside sources that might have them?

Dale there are no sprockets that will fit the 9 spline shaft. Find some old junker tranny's and rob the shaft they are all interchangeable. nly difference are some are 2 key shafts some are 4 key.

How do your clutches actually work? Do they loosen the belt and let everything loose power or is it a setup that a clutch atcually throws and the pulley is disengage like on a dirtbike (how the chain continues to move and it isn't loosened allowing everything to slip persay the sprocket/pulley actually disengages!)

Could you possibly use this clutch?

Or is another clutch better? If so please leave a URL Address and a brief description if the URL doesn't take you directly to the page!![/url]

All classes except FX has to use an oem style belt acutated clutch. It tightens and loosens the belt to alow it to slip or not slip. The noram mini cup clutch is what I use on my FX

George for right now I will not be able to race but I am building 2 machines one for my cousin that will go about 22 mph and the other for me. these machines will not be raced at this point and time, but i want to learn and build these 2 machines as a starting point and to be able to work out all the kinks and then build me a baddd racing mowchine!!! So i guess all the info you can provide me doesn't have to be based on USLMRA but if it is I guess it needs to be F/X based! Appreciate it

Oh yeah where is that clutch located on the web? I went to their website and couldn't dind the mini cup! And how do you engage and dissengage the clutch? Do you use a pedal or handle or is it diff.???

Oh yeah you can visit my other topic in Driveline under the gearing topic and see what i want out of my mower at this point in time!!! And I wouldn't mind going 90 the 60+ number is something i pulled out my head. I have raced cars at over 145+ mph!!

Appreciate it all!!!

Thanks

George it'll be ran based on a 14.5 OHV with everything done to it except crank. There will be no governor except for what i govern with my hand/foot from a read off of my tach! I want this thing to squill, burn, slide, drift, haul butt, maybe even "cat walk" it!  Does the clutch atctuate itself or do you relieve a pedal or handle?? Or is it like slow build up the boom! Because i wouldn't mind have like a motorcyle or racing fourwheeler clutch. Has that been done?

Thanks

Its a centrifucal clutch rpm activated. If you want to squill burn out drift and kick but you might be best with a car. Sounds safer anyways. A mine has close to 50hp and it is a hand full. It dies all you want but if you did it all the time it would get expensive in repair cost's.
