62 window crank handle

[Chris H.]

I had a plastic handled window crank in my 62. I found a couple of handles that looked identical to the one good one I have.

However the part number on mine is in the large round end and the two I bought have it on the back of the crank handle lever. 4151869 p/n

which is original and is there any discernable difference? Are these NOS?

Re: 62 window crank handle

Correct handles have NO plastic.

Chris--
I think the number is 4151868 rather than 69--you either have some NOS ones there or some repros. Compare the quality with the original, and if identical, those are NOS. Repros may, or may not, have "Taiwan" on the back.

Re: 62 window crank handle

Mike, you can zoom right in and it is pretty clear that it is a 9 on all 3 parts and they are pretty identical on the face side. However on the back they are slightly different and therefore came off different tools. The two I assume that are NOS have a shaft hole style similar to my later plastic handled replacement.

The AIM and my 53-72 parts book says I should have 3725377. What is going on here?

Thanks, Chris

Chris, could the 3725377 be an assembly number?

Re: 62 window crank handle-part number?

yes Art it probably is, but the 4151869 cast in number is a later number than the 3725377. I assume both of the numbers are Chevrolet numbers and therefore should be in year order with the 415xxxx coming later. Perhaps Joe can answer?

If the numbers were closer I would wonder if the 4151868 could be the chart/casting number with different knobs used on different cars. In later vettes the knobs colors matched the interiors. I also just noticed that my parts book states that the 3725377 includes knob. hmmm again strange that the cast in number comes later than the assembly number.

Re: P.S..............................

It is under my interior and should have shown up with the handles displayed?

Re: 62 window crank handle-part number?

Well Chris, ya know what the real meaning of assume is don't ya?

4151869 is a Fisher Body issued number.

Chris----

As Art mentions, the 4151869 is Fisher Body part number. The 3725377 is a Chevrolet part number. In this case, the 3725377 is the part number for the finished window crank ASSEMBLY. I strongly suspect that the 4151868 is the casting number or part number for the just the zinc diecast component of the assembly. This part may have been used for other GM vehicles and does not identify any, particular, finished assembly. Very likely, the Chevrolet part specification called for the 4151869 casting to be used with a certain knob to make up the 3725377. That, particular, finished assembly was a Chevrolet part and it was uniquely applicable to 1956-62 Corvettes. This, particular, part was the only part ever available in SERVICE for 1956-62 Corvettes. It's possible that other parts were used in PRODUCTION, too; I don't know that.

yeppppp....I knew I should not have used that word.

that makes sense then. Cheverolet borrowed the arm from some other GM car and probably designed up their own knob. Parts bin engineering!!

Chris--
You've made me think--a dangerous thing to do!!!
Here's what I've found:
I have 5 NOS cranks (in 4 different sizes of original GM boxes, by the way). All have the 869 number, and all are cast along the backside of the handle, not around the circumference.
I have one with 869 on the circumference--that is the only one that also has a patent number.
I have three used ones with 869 on the handle.
I have two used ones with 868 on the handle.
I looked at the back side of the handles on the three unrestored cars I have-- couldn't find part numbers on the backside of the handle--that would lead me to believe that these have the numbers on the circumference.
All the above used cranks come off of original 62's.
The ones that have the numbers on the backside of the handle also have a code--
one of the following:5B 1B 5C 4B. I am convinced that those are mold numbers, not dates.
The reproductions I have, by the way, have the "Taiwan" cast in an area that would be invisible when installed on the car. The only discernable difference I find is the peening of the back side of the actual knob's rivet.
So, now that you woke me up on all this--this is what I can tell you. It has no real value, but I managed to fill several paragraphs--that's what a day off is for, isn't it!?
