Is there an factory orientation that the window cranks should be installed on the mechanism shaft? I recently purchased the Ford equivalent of the Assembly Manual and noticed that the angular postion of the window crank is actually a called out spec.

Re: Mid Year Window Crank Installation
Position of window crank handle installation was documented in your AIM for a reason--that's the way the factory wanted it! What's documented in the AIM was within easy grap of occupant(s) with windows in their up position and gave max leg/hip clearance with occupant(s) seated. Expect savvy interior judges to inspect/check and take appropriate deduction(s) based on the INSTALLATION component of originality....- Top

Re: Mid Year Window Crank Installation
Jack,
How is it documented in the AIM? I see a drawing but I see no notation as to their assembly position. I would think that if GM had a prefered position, there would be a note: Position as shown with window raised.

Excellent Point!
Thumbing through AIM books ('61, '66, '67, and '71) you are ABSOLUTELY correct! There is nothing more that artist's interpretation of the position of the crank on the shaft and no note regarding window lift up/down!
The same is true of the orientation of the outer door lock cylinder. Only an artist's interpretation of it being installed such that key enters with teeth down vs. teeth up.
But, you can expect NCRS judges to look for these assy norms and deduct for restored cars that deviate. Only thing I can say is practices like these may have been used so long at GM, they were basically understood without the need for clarifying notes on the drawings....- Top

Re: Excellent Point!
Jack,
In the 60's, I worked in the service department of a Chevrolet dealer and several times, the topic of random installation of parts on new cars would come up among the mechanics. One particular item I remember was the placement of window cranks, especially on 4 door cars. A new Chevelle 4 door had the left front and rear window cranks at about 6 o'clock and 8 o'clock but both right front and rear cranks were about 11 o'clock, not at all symetrically opposite. That told us the worker on the right put them on one way and the worker on the left put them on another way, quite randomly. I always thought that was strange but of all the new cars we looked at that afternoon, none had matching crank positions, even several new Corvettes that were in stock. The majority, as I remember were about 8 o'clock on the drivers side. I suppose it was just the easiest way for the worker to install it. While holding the crank knob with the left hand and using the right hand to push on the center of the handle, the 8 or 9 o'clock position would be the most logical position, IF he was right handed etc etc. And so it goes... There are probably a lot of reasons why they're in all different positions.
When there is a specific reason why something must be installed a certain way, it's almost always noted in the AIM. I know over the years several judges were deducting points if all the hub cap spinners weren't mounted in the same clock position on the cap. I totally disagree with that. I really think that's going way overboard and it's not at all accurate judging, just picking. I really like seeing a restoration with a certain amount of slightly questionable items, as long as they would be considered "possible" and I've sure seen a lot of that on totally untouched original cars.- Top

Re: MORE
Joe:
I'm disappointed to hear that Ford specified the position of the crank handles, whereas Chevrolet did not. My personal preference is to have both the main and vent cranks pointing down-and-away from the occupant. Although what Michael says is probably more correct, from both a LACK of quality control and safety aspect, I just prefer them in that orientation. Ford seems to specify up-and-away, as opposed to down-and-away.

Re: Excellent Point!
Fisher Body always specified on their O.D. (Operation Description) sheets (FAR more detailed than Chevrolet A.I.M. sheets, as they described the assembly process) what the installed position of window/vent cranks should be, but installation was sill random in most cases, as nobody paid much attention to that level of "nitpick" in the 60's. Chevrolet never specified that level of detail on A.I.M. sheets (or a detailed assembly process with tooling callouts), and didn't have a "Body Specifications Manual" like Fisher Body did. Anyone trying to make a judging call on crank positions based on Chevrolet A.I.M. sheet illustrations is "inventing" a specification that never existed.- Top
