if your not going to race it, just ahve fun, thenput a big ol single cyl motorcycle engine in it!
I have an old 4 wheel harley golf kart with a KZ 750 4 cyl shaft drive in it. Its great fun!!

Now as for the reverse gears and chain, toss them out.

I guess A/P guy's cant do that since it must utilize a shiftable lawn mower transmission?

it says shift, not reverse. Ive got a couple 4 speed trannys off of an old fiberglass bodied international rear engine mower that has no reverse from the factory. It just needs to shift, not really need to shift to reverse.

Jeff no one using the 700 series tranny that I am aware of uses the reverse. If the chain breaks and it will, it wraps around the shafts and totally destroys the tranny. It only has to be shiftable in gear and outta gear.

I was wondering why you don't use needle bearings on the output shaft? How often you have to change the bushings?

George Herrin · « **Reply #38 on:** April 14, 2006, 12:05:06 am »

Sorry I havn't answered this sooner not sure why I didn't see it. I never used the needle bearings because of the extra expense in the machining to make them fit AND I have never had a bushing fail and change them once a season (during the off time) And why fix what isn't broke. I have Many feature wins multiple championships and 6 years of racing and can count the broke trannies on one hand. So you see why I never machined one for the needle bearings on the output shaft. I have run a couple with the ball bearing like a 700-039 and those work well but they are made that way from the factory!!!!

George Iwas reading thru your article again and in there you say you gear to race in third. Does that mean you swap gears around in there? Wasn't sure what you meant there. :?:

Squidd · « **Reply #43 on:** May 29, 2006, 01:40:40 pm »

Third is "generally" (but not always) a 1:1 ratio on counter shafts ...meaning the gears are the same size...(tooth count)

So you not overdriveing or under driveing "inside" the case..and end up with a true 3:1 from input to output shaft...(bevel input to spur)

Do you get these 700s out of a rear engine mower ?

And is that the best for a S / P or will a transaxle work just fine ? Thinking a S / P will be my next mower after a year or two of IMOW.
