K-restoration blog updated - Drive shaft stripes

Sure wish we had this kind of documentation for a Dearborn kar. I assume you will pass this info along to Jack?

From the original Ford Motor Company released engineering drawing for the Hipo driveshaft assembly engineering part# C4ZW-4602-E (2) paint bands 1" wide for identification approximatetly in the center of the tube GREEN & VERT (two different shades of green).

Per another note on the Ford drawing: "After balancing-daub with yellow paint the light side of balance condition"

Balance weights can be located at the front or rear of the shaft within a specified distance from the(ends)center line of the U joints.

BTW:distance between the center line of the U joints = 49.70"

From blog:

"I found yellow paint splotches all over." Not sure where you found the yellow paint....

The pink paint on the differential end of the shaft could indicate the U bolt nuts were torqued to spec. during assembly.

The Ford drawing indicates that the driveshaft was shipped to the assembly plant as a complete assembled driveshaft DRIVESHAFT ASSY. PART NUMBER C4ZW-4602-E. The assembly includes balancing, yokes, slip yoke, tube, front & rear U joints,(the rear U joint was retained for shipping),grease etc.....Your picture shows a balance weight on slip yoke/front end of the driveshaft. Hence the yellow paint to indicate the driveshaft was balanced????

Each of the components(yokes,slip yoke,tube,U joints,etc.)that make up the driveshaft assembly have an engineering part number.

The Ford documents I have do not reference any pink paint. I would assume the pink paint was applied during vehicle assembly to indicate an assembly process was completed to specifications???

The original driveshaft from my late March 66 San Jose car had a large yellow daub at the very rear.

The pink on the end looks like it was applied before the u-joints were installed. I should have the original u-bolts, which I'll clean to look for pink paint. ...........

Really doubt that the pink has anything to do with the U joints. instead (like the later drivelines) would think that they might have identified the cast end so that the guy putting together the driveline could tell that particular size from the others.

Of course there is documentation for the later (66 cars) for the yellow use. The document states that its purpose was to allow a service worker the ability to reinstall the driveline the exact way it was originally. This helped (Ford hoped) address the ongoing complaints of vibration at or about 35-45 mph

I notice in the pic of your driveshaft that the front UJ has the circlips whilst the rear has the flush caps.

Mine is the other way round - all of the front caps are flush, with the two rears having circlips.

Is this a huge problem or can I leave it until a joint replacement is needed.

Thanks Mark

It is the pic from the resto blog above of the K convertable driveshaft dated 30 December.

Second pic down shows front joint with spring clips on the caps with rear joint with flush caps.

As prevoiusly said my front joint has the flush caps with two spring clips on the rear caps that are not in the diff yoke.

I wondered if it would be ok to leave the front caps as they are, I did not want them to move out as they have no clips to hold them in.

I can see that the shaft has been assembled back to front.

The enlarged pic you have just sent shows the bearing caps retained by spring clips.

At the axle end of the shaft the bearing caps have no spring clips.

Mine is the other way round.

From a safety point of view should the front UJ bearing caps be retained by spring clips?

Caps flush with the outer face - no spring clips front joint

Recessed caps - with spring clips rear joint

I think the penny has just dropped - outerlocks = springclips.

So springclips on both ends - I will get another joint for the front.

Thanks

Thanks

Now sorry to beat this to death but what the heck is an inner lock ?

All the joints I have ever come across have clips on the outside to hold the caps in.

Is there something that holds them on the inside or are those front caps just an interferance fit.

Thanks

There will be a C clip on the inside of the yoke.
