    Well.... The new motor is known as a 12v and my trans is a 6v.

    What the means is the flywheel is larger 200mm as opposed to 180mm..meaning there are more teeth (larger diameter) and we have fitment issues with the trans bell housing and the starter.

    Combine that with the current transaxel being almost 50 years old and tired, now would be the opportunity to get a rebuilt late model 12v transaxle....

    :D

    One thing leads to another..

    Thinking of what's known as a "Pro Street One" build..

    Super Diff
    Aluminum Side Cover
    Welded 3-4 Hubs
    Hardened Keys

    Or.....Get out the air grinder and safety glasses ! Not that bad of job, VERY helpful to have a 200MM flywheel to test fit along the way !
    Swap out the starter bushing and starter then You're good to go !

    I thought about that... the main shaft has a good amount of play, the seal is leaking, the motor mounts are shot, the cradle is bent, It's a 6v trans, it's almost 50 years old....

    The thought now is stay with swing, or spend a bunch-a-money and go to a Bus Trans with a nice IRS suspension???

    Swing is strong and dependable and can easily be worked on.. and at the speeds I travel off road is just fine...

    The Bus IRS set up??? Super trick, tempt me to hall ass and more expensive..

    Decisions, decesions...

    The input shaft on the transaxle will be somewhat "loose" until it is supported by the bearing in the flywheel securing nut. The seal is easily changed out too... I'd do a little flywheel clearancing on that 6v transmission and use a self supprting Bosch starter SR-17 (no need to change the bushing) and run it until it doesn't run any more. These are fairly stout transaxles that are under stressed in a light vehicle like a buggy powered by a stock(ish) engine.

    Going slow on this project... :lol3 Too much other stuff going on..Life that is.

    Just got my Transaxle back rebuilt from The Wright Gearbox.... ProStreet plus they call it.. SuperDiff, welded gears, converted to 12v surfaced the Bell housing opening for a 200mm Flywheel, 12v busing for the starter...(HD parts, Aluminum side plate on the Diff side) should be good to go..

    Ideally I get this thing running in the month of August.. That is the goal and will post back pics and progress.

    :lol3

    The Motor was $1700 and the Trans was $800....

    :clap

    all the miscellaneous will put me over which is OK... I was going to re-build the whole front suspension but will wait on that.. Will be installing Front Disc brakes as the Drums are virtually worthless.. Stopping is an important part of "Driving" and to be taken seriously.... Stopping poorly can leave one in bad spot...
