Thanks.
I have quite a few old parts without coating, only copper or brass.
The new copies are made of shiny chrome. 😬
That's why I asked because I wasn't sure.
I'll give mine for the galvanization. After a year, they patina on the mat.

The valve springs came from Austria in original Terrys packaging. Collar from Zundapp slightly reworked to fit inch dimensions. I'm assembling the engine tomorrow !!!
Unless the wife comes up with other, more important home and garden tasks. ☹️
Cheers
Paul

Another problem arose when assembling the engine.
The diaphragm (E1469) is missing in the crankcase breather. I don't know how it is constructed or what it looks like. Is this sleeve in the middle of the body (E1466) a plug (E1464)?
Do you have better photos of these items?
Parts from mine in the photo.
Regards.

It's usually the case that the diaphragm is missing, I think they just corrode away? It's best sorted now because it's impossible to get to without stripping the primary case off.  Brian Tillin has a knack to repair these and should be able to give you details or parts.  Ron

Hi,

Brian is a good idea if he writes back.

Unfortunately, valve collars from Zundapp was not a good idea. After folding, it turned out that the valve springs are not compressed enough.
I made technical drawings and commissioned collars and split cotter to be made in small series. The split cotter have been hardened. IN its old, original. EX its new.
After folding, everything fits.

Hi,
The breather nozzle in sleev nut was missing from the engine. Probably some genius mechanic had decided that it was unnecessary earlier.
Fortunately in the parts that were left over after the renovation from 1987of the civilian version. My dad gave me new parts and I hid the old ones. Fortunately, he made two diaphragms. Today, the old nut and the new diaphragm have found their place in the engine for the military version.
Works perfectly as a one-way valve.
Regards
Paul.

While working with the Triumph fuel system, I reconstructed the fuel pipes in my NSU 501OSL and Quick to their original condition.
The big NSU lights up and works. There is a problem with gear shifting (adjustment). Quick needs a little more work.

I already thought that the one that was run over by the tank is yours.
This is the big model 351 or 501. Uffff.....🤣
How was your 251 in condition before overhaul?
