12V engine to 6v trans…HELP!

[Mrorangecrush77]

I have a 1970’s 1835 (originally 1600) that I am attempting to stuff into a dune buggy, the title for the buggy states it is a 1967 however it seems that the Trans/starter are both 6V, is there a way I can put a 4 dowel flywheel onto my 8 dowel crank? I have the original flywheel for the buggy (motor was locked so I pulled it apart and purchased this 1835) and it’s a 109 tooth. Is it possible to hook up the 1835 to the swing axle?!?!? I’m going in circles finding ways to get it to fit!

Remove 4 of the dowels.

Not if you are trying to put a 12v flywheel onto a 6v crank.

Just clearance the 6v bellhousing and and use the later engine as is. Use a 12v starter.

Thank you for your reply’s, I pulled 4 of the dowel pins and the pins I pulled fit perfectly in my 6v flywheel, I attempted to put my 6V flywheel onto the crank and it looks like 3 of the 4 dowel pins start to slide into their respective housing, however it seems as if 1 pin out of the 4 won’t go on. is there a better way to pull pins? I attempted to pull the remaining 4 pins and had no luck.

In regards to the clearancing of the transmission, how might I even go about doing such? I am somewhat of a Novice when it comes to putting in engines and so I’m not sure how to make sure it’ll work, I assume ill need to get a 12V starter and that’s it? If anybodys got any more ideas/links to parts please feel free to send them over!

Pulling dowels that are properly installed is nary impossible without destroying the dowels.

Remind us, why just not use the later flywheel on the later engine? I'm just not understanding I guess.

You only need to clearance the bellhousing a little bit. Starters are not that expensive. If you get an autostick, you don't need to fool with that stupid starter bushing. I got one at Autozone years ago. Never a problem.

Also, you can use a 1600 clutch that will give you the correct clamping force. You may end up driving through the smaller 6v clutch. Just use a pressure plate WITH the centering ring.

The rest of the buggy is 12v already. You can run a 6v starter on 12v, but the bendix will slam into the flywheel. It can cause damage over time. Using the 12v starter, this goes away.

Also, you won't have a Frankenstein setup.

I see more downside to what your trying to do than just using the 12v setup complete as a unit.

Just my .04c (inflation and all)

Way less involved to clearance the bell housing and change the starter if th car is already 12volt, plus you'll have a bigger clutch. Make sure you have a collared pressure plate to match the TO bearing. If you switch flywheel do you have the ability to check/ set the endplay? You can't just swap flywheels without doing so

You can use a 12v battery on a 6v starter it has a lot more umff staring than a 12v starter but works fine, you will need to fit a 12v dyno/alternator though, no way round that one.
