paint marking on drive shaft

[Keith G.]

What are the paint markings on the long drive shaft for a 67 300hp, 4 speed. I did try the archives. Looks like there was 2 towards the front that went all the way around.

Keith,
I've seen green and orange bands painted around the drive shaft, And at the rear u joint there typical is a green swath on the drive shaft and a blue swath on the rear end yoke. I don't know what they signify. Perhaps for balance.

Here is how my drive shaft and half shafts were done for a 427 - 390. Hope this helps.

Re: paint marking on drive shaft

The paint bands (or stripes) were put on the driveshafts for the benefit of the assembly line workers for various engine/transmission combinations. However, the 63-67 Corvettes used only one driveshaft for A.T. & M.T. models, GM # 3830618 (2.00" dia., 29.90" c/c u-joints, 0.095" wall thickness). The 68-E70 Corvettes (exc. T.H.) also used the 3830618 driveshaft. Driveshaft # 3963852 was used on L70 Corvettes (same dimensions except 0.120" wall thickness). The 68-70 Corvettes w/TH400 used driveshaft #3924148 (2.00", 29.50" c/c, 0.095" wall thickness).

The paint bands must have been put on by the manufacturer of the driveshaft. The Nasty Z28 website has information about paint bands on 2nd generation Camaro driveshafts.

Jeff,

Are the stripes about 3/8" wide? Is the green just a spot (not a stripe) on the yoke? I assume the stripes are located at the rear of the driveshaft.

Re: paint marking on drive shaft

Here are photos of my original driveshaft, before and after restoration. The stripes are blue and orange with the daubs on each end being green. In my case the stripes were about 3/4" wide. I believe stripe width varied with how the operator held the paint brush as the shaft was turned on a lathe or balancing fixture. That is why some stripes are narrow and some are wide in the various examples. In my case the stripes were toward the transmission end of the shaft....

BTW, The car is a 427/390 with an M20

Re: paint marking on drive shaft

Here's my 67/300 shaft. The stripes are 1/2" wide with aa 1/8th gap inbetween. I think the width of the strips would vary quite a bit. The stripes are orange and green, I don't think the green stripe was blue that faded to green but anything's possible,it does seem to have a blue tint in the pics but looked green in the sunlight. The paint daub at the yoke looks like lime green definately different from the stripe. And the stripes are at the differential end not at the end with the trans yoke ( U-joints looked origional). I think the stripes could be on either end, there was another post about this a while back.

I didn't see a paint daub on the opposite end but it may just have been gone.
After cleaning (glass bead) , the stripe location is still visible.

Yes; found mine to be approx 3/8" & the green was kind of a 'dab' rather than a stripe. Location at aft.

I wonder if the transmission had anything to do with color or width? Mine is a 427 /390 with M21 and I was told the stripes should be green and orange and about 3/8" wide.

Re: paint marking on drive shaft

I don't think GM would rely on the paint width to mean anything.
Colors yes, but not the width...

Michael -

Nope, all midyears (from '63 250hp Powerglides to '67 L-88's) used exactly the same driveshaft; it was received at St. Louis as an assembly, including the front yoke and both U-joints.

Here's yellow and blue on the differential yoke of an early '65

red and green stripe copied from original:
here is a photo of my restoration, note the seam heat weld discoloration and at the yoke. I used an original one to reproduce as close as possible.
