Z1 Fuel Taps

[DogsbolloxofZ1B]

Calling all mechanical engineers When I was a lad, long time ago now, I used to work alongside some mechanical guys who used to have a process that applied metal to shafts to build them up to be final ground back to size.
It wasn't sprayed on but almost like chroming process.
I need to find out if anyone out there does this and could build the shaft of a Z1 fuel tap up so I can machine back to best fit diameter, they're a bit thin walled to sleeve.

I've tried all sources of the replacement seals and the only one that worked out of the bag were the Black ones that are now discontinued from USA. The problem is the fit of the shaft within the seal, no shit Sherlock, and given the age of these things all the taps I have have some wear so need to be built-up in some way.

Anyone done this

Are you using any lubricant between the tap shaft and the inner bore of the newly supplied seal
I use red rubber brake grease on the tap rebuild,if you have not already tried this :
Have the new Brown items failed?

Steve,
Yes tried the Red rubber grease, soaking in fuel and still they won't seal. I've even tried shimming beneath and around the outlet hole and no joy. If you place the sleeve on the lever and apply the smallest amount of force onto the seal it works so a few thou build-up on the shaft should do the trick.

I'll let you the outcome of my experiments. Also spent ages restoring a few Z1 horns, that was another joy
Cheers Mike
