Small Parts and a Big Part
Posted by: WhenIm64 ()

Today I have questions concerning a few more small parts, but first, a question about a big part:

I have a used Corvair crankshaft, just one. But I no longer remember where it came from, and I do not know whether it is for a 145-cid or 164-cid engine. What visual difference might I see to make that determination?

Now, on to today’s photos, below.

#1 shows three Corvair engine oil dipsticks. They’re all the same length, but as you can see they are different at the top. What, if any, significance is there to these differences?

#2 shows a small bracket. I am about 99 percent sure of what this is, but I am seeking confirmation (or contradiction).

#3 shows two pairs of bolts, each sharing a common nut. The nut is about 2-7/16" long.

Thank you for your help. I’m having fun sorting through all the parts I have accumulated through the decades; I hope you don’t mind these periodic questions.

–Bob

The center dipstick matches the one in my very original 28,000 mile 62 Monza Sedan (84 hp).

Enjoy the Corvair!

Bracket #2 goes on the clutch end of an FC clutch cable. Clevis pin goes through the big hole, rear cable spring through the small hole.

How about the large casting number? That is a very visible part that is different between 145 and 164. grinning smiley

BTW, you got an answer back in 2012.... smileys with beer

This is why having a Junkyard Primer is important.thumbs up Helps the memory bank.winking smiley

So important, I took mine apart and scanned it to load into my phone and iPad. I also loaded the shop manuals from the Corvanatics site into my devices. very handy for tech sessions.

OK, too much suspense, if the casting number is 8409, it is a 164 crank.

And if there is an ampersand (&) stamped in the rear front flange grinning smiley, near where a pilot bushing would go, it is a nitrited crank from a turbo or 140.

The 1st pic the one on the right does not look Corvair at all, the other 2 can't tell if it's the pic or what but looks like there is a bead or wire wrapped around from top to bottom.

That's funny, the one on the right looks just like the one in my two '65 Monza engines made one day apart.

Oil dipstick on the right was on all LMs I scrapped. Also my Coupe and my More Door (80 hp). Greenbrier's 80 hp was changed out to the one on the right from the one on the left.

Vern, thank you, but I think my photo misled you. There is no big hole nor small hole, both holes are the same size. Here are two more photos that I hope will show the part more clearly.

#3 is for a 65 standard transmission shifter at the rear where the "reaction rod"(?) attaches to the
transmission cross member.

Tim that is what I first thought but the part that you are thinking of is 5/16"x 18 course threads and those look like fine threads and those bolts are too long. Your application would be for all late models with a manual trans. That bracket also looks a little too thick.

Okay, #3 is proving to be a stumper so I'll throw in my own guess.

I think they are related to securing control arms to crossmembers, possibly on Forward Control models, maybe also earlies but certainly not lates.

But I really don't know.

You may be right Bob. What size are the threads? 3/8s or 5/16s?

Hi guys, I'm rebuilding a 65 180 turbo engine. The bearings that were in it were all std size. The crankshaft has the part # 8409 on one side of the throw between main journals # 3 &.4, & 16 B on the other side. It has the letter R stamped on the throw between mains # 2 & 3. Also has G M T on throw between mains 1 & 2. I could not find any ampersand anywhere on the crankshaft. The area around the flange near the pilot bushing has no marks.
Do you think this is a standard shaft, not a nitrided one ? The engine s/n indicates that it is in fact a genuine 65 140 or turbo Any feed back ?

Yep, no Ampersand means no nitriding.

Here is a link to a picture on corvairforum.com

Unless you are going to run it hard a lot, I would not worry about it, just use a good harmonic balancer, not an old one that has dried up. Other might chime in.
