Does this mean a new crankshaft? -- Flywheel Pins

[zachswy]

Like the title says. I've got a '77 standard. To cut right to the chase, looks like my flywheel and crank are ruined, but I'm wondering if y'all think these can be machined and saved, or do I need to split the case and do a full rebuild

I also look to have a ding in the side of my case:

It doesn't leak, but should that concern me?

Crank, pins, & flywheel are junk.

You can try using a 8 dowel jig to drill 4 new holes. Obviously the dowels and flywheel must be replaced.

"Crank, pins, & flywheel are junk"

That's what I thought -- Thanks for the speedy reply!

I believe that 4 new holes can be drilled

Thanks for the input, all. I doubt larger pins will work, 11/32=0.32375, and according to my calipers, the smallest of the wabbled holes is about 0.406 wide. But I'm going to call around to a few machine shops and see what it'll cost to have it done. Not confident enough to just take my Makita to it and hope for the best, but if I can avoid chucking it, all the better.

This is my first post on this forum, and I'm already floored by the helpful, supportive Samba community!

The question really should be “How long do I plan on keeping this car” you can kind of patch it up drilling four more holes but you also need to get the mating surface crank flat again, when the holes wallow it makes high spots and you cannot not get full contact between the two parts.

I’ve seen this done many times and sometimes successfully, often times it’s a bandaid fix and it happens again. Be sure to get the endplay set correctly too. If it were me I’d fix it once and do it right, this means tear down. So ? If you patch it up be honest and disclose to buyer when you sell.

Upon closer examination look at that crank again about 2 O’ clock and 7 O’ Clock position I see what appears to be a crack radiating from dowel pin hole. Then again may just be a shadow. 😀

Zundfolge1432 -- those are indeed cracks., and though I didn't mention it, they are cause for concern. Plans for the car is to keep it. I actually bought it about a year ago for what still is a great price for its condition, and I find the work enjoyable. My kids (soon 5 and 6) will need something to wrench on when they get older, (I hope), and it's a nice yin and yang match to my '47 Willys CJ-2a.

With the input of the forum, I think I've decided to consult with a local machine shop -- if they think it can be drilled and prepared in such a way that it will last long-term, I'll pursue that route. Otherwise, I'll just knuckle down and get a new crank and flywheel. -- Fortunately, nothing for these cars is terribly expensive.
