Topic: 9" gasket

[jwc66k]

Don't know if I have those Assembly Manuals, but have you checked there in the notes?

That is not covered in the Osborn Assembly Manuals as the item was delivered to the line as a complete assembly. The "best" reference would be the service manual, as Ford Car Parts (aka MPC) usually does not include an assembly sequence, just a "this" goes "there" reference.

For reference my April 1969 MPC lists the gasket for 9" and 9 3/8" carriers as B7A 4035-A. Apparently after the April 1969 revision the part number was changed on that gasket.

I could not find the 9” stash, perhaps all sold.  But for NOS C9OZ-4035-A the thickness is 0.0325”.  Pictures attached. Maybe this helps...maybe adds confusion. Hopefully the former

The axle assembly drawing is a 1970 revision. I don't see any reference to sealant either in the illustrations or in the MPC so I doubt Ford used any.

Yes would not expect it to be reflected on the exploded view illustrations. Thanks for looking into the subject - both of you

I received a reply of no sealant used from factory on this one. - Thanks

I would recommend you take a quality flat edge to the housing to see how flat it is.  On my 66, it was nearly 0.050 out, and the gasket could not stop the leak.  If you have to use sealant, keep the amount small and out of sight.

Checked and no sealant used originally- .

The place where they are prone to leak is if you do not use the copper crush washers like the factory.
