12v system in a 1300 bellhousing

[amelchert1]

I am starting to paint my 66. The primer in on and the engine is out. I would like to go to a 12v system and ditch the 1300. How do you grind the bell housing in order to fit a 12v flywheel?

you're going from 180mm to 200mm so generally speaking you don't need to take a lot off. A Dremel and some grinding bits on the mounting stud surfaces, the top, sides, and bottom of the bellhousing, and you should be good. Take your time and don't take too much off.

Here's a decent video on how to do it.

Like he mentions, if you pull the flywheel (or if it's a new build, don't bolt it up until you clearance the trans), it'll help a lot. I know he's not a fan of the "let the engine finish the grinding" method, but it does work just fine. Just make sure once you do it, you pull the engine again and clean out the debris. Don't run it with those chips and shavings in there.

Although, I was pretty sure the stock transmission, like the stock case, were made of magnesium...

Thanks for the info. I wanted to ask before I did something drastic. This was a good video. All of his videos are informing.

Without looking at the video ...

Grind down the four points inside the transmission closest to the engine stud/bolts. You'll want them flush to the bellhousing on the top, and almost through to the stud holes in the bottom. Make sure to remove the throwout bearing to keep it from getting full of shavings, or mask it off real good, and thoroughly clean the bellhousing after grinding. If you have a spare flywheel to test fit for clearance, that would be helpful.

A Dremel seems kind of light duty. I prefer a die grinder. Make sure to wear eye protection, coveralls, gloves, a mask and a hat, because those shavings will get everywhere. You'll also need a 6- to 12-volt starter bushing or switch to a self supporting starter.

When installing the engine, snug the bolts until the flywheel starts to rub, and back them off until it turns freely. Then start the engine and tighten the bolts and let the flywheel finish the clearancing. It will only divot the bellhousing a slight amount. There will be no additional shavings.

Is there a new location for the video(s)?
