clutch Z bar finish
« on: December 30, 2015, 01:20:32 AM »
I was wondering if my Z bar got short changed in the plating vat? Is this normal? looks like part of it was sticking out of the mix!

 It may have been! I can tell you for certain that on my '67 NOR, the BB Z-bar was originally phosphate. I also have a NOS SB z-bar I recently found in its wrapper collecting dust in my shed and that has a greenish hue phosphate.
Today it would be considered gray but when it ages it turns towards a greenish hue like an old firearm. It looks like phosphate in your picture.

I think its phosphate and I didnt clean it up yet. I thought the whole thing should be the same finish. I might leave it like that if it cleans up

Hi Bill, sure looks like phosphate and probably is! On our 01B 68 our bar did not have any phosphate and just seemed like a piece of metal with just a little type of greenish hue to it so maybe it had some type of coating. It had very minor rust so on mine I soaked in Evaporust and then protected. Here is a picture of mine installed. The spring had what seemed like a type of aqua blue paint on it which like the Z-bar I only soaked and protected similar to the Z bar.

Hi Chick,

 That greenish hue should be aged phosphate. Many times it will change color due to preservatives such as oil. With firearms it was due in part to cosmoline. The hardness of the metal has a lot to do with the hue also. I have parts I used a gray phosphate bath for on things like pulley's which came out dark gray and the bolts (harder metal) came out with a green hue (after preservative oils were applied).
  That picture looks good!
