Topic: Early 4 Speed manual transmission shift control assembly (7400) finishes

[Bossbill]

I thought I'd use the nebulous term "early", but I suspect this may apply to 65-68.
I'm redoing my shift control assy (shifter box part 7400) and wondered if I have the finishes correct..
Cad=shiny Cad plate..
Referencing the attached starting at approx 12:00, counter-clockwise:.

• Main 'body': 7416: Cad

Yes and no. You are using a service drawing which does not usually contain the full hardware part number - specifically the finish. The Ford locator code associated with the hardware item has the item's finish "built in" to the number - but you don't know what it is. For service use, one finish for any one hardware item is all that is stocked on the shelf. In effect, you don't know what the assembly line used. On the bright side, what you listed is probably the correct finish.
Attached are four pictures of the one that was "left over" when I rebuilt three of these, the best of which went into 6S1902.
You might consider using the full Ford hardware number - it has a dash and a capital "S". A "-S" without any number has a meaning, no finish. A "-S7" means Cadmium plated, etc.

Excellent pics, Jim. Thanks.
The service blow-up was meant to be a parts identifier. It was a generic "Ford 4 speed shifter" illustration. The Assembly manual is no help since it comes to the factory floor as the 7400 assembly and no details are offered.
My shifter was coated with a zinc phosphate done in an effort to restore it. All original finishes were gone.

The 376444 bolt was not found in your spreadsheet. The 34940 is listed for other applications with an S36 finish. Your picture shows them as cad plated, so I'll go with that.
I may have to rig a fixture in order to get the saddle pin (378492) out. The hammer and drift method doesn't move it.

Bill,
Yup. Thanks to you, I got some research to do on seven pages of shift mechanism. For some reason, I missed 376444-S7 , and it is shown as a -S7 cad plated bolt (Sec 73 pg 6 - under 7348). Some hardware items were documented, some were not (must have been a bad batch of Bourbon that night).

One more thing - wavy washer, 351467-S (5/16WAVY,0.375ID,0.781OD,0.017T,SGL WAVE) is not reproduced. In its place I used 356297-S2 (5/16WAVY,0.380ID,0.750OD,0.010T,SGL WAVE - AMK B-11590). AMK list it as for Ford Shifter linkages. As it's 0.030 smaller in diameter, I doubt anyone will notice unless it's pointed out to them (but I won't do that).

My wavy is still usable. More of a pageant wave than wild wave now.

How did you come upon the treatment for the large "rod?" Looks like black dichromate.

I got the small pin out, but it took some heat.

The U-shaped cast steel piece is repoped and mine has a bit of slop in one hole.
Hmmmm.

WYSIWYG sucks, hence multiple edits

Excellent thread. Thanks Bill this is exactly what I was looking for.
