NZ 350; 3 or 4 "Kork-lamellen"

Post by martdapp » Tue Apr 13, 2010 11:01 pm

Hello, NZ-enthousiastics
Here a technical issue. If you look at the spare part list nr. 58 of NZ- models, on page 18 can be found the clutch parts. The Figure shows 3 "Korklamellen". In the workshop-manual is an average of the engine block, each with 3 blades. Odd as it is, on the opposite side is the infliction of "Fit 4". The NZ of a friend has a not so well-functioning clutch (clutchhandle is heavy and switch is not so great). When disassembling the clutch, it shows 3 lamellen. Is it possible that 4 must be installed? Anyone who knows out there?
If it is true, that 3 blades are enough, how to redress the switch then?
Is it perhaps the oil (for the summer SAE50). Should he use thicker oil? Could it be due to the length of the pen pressure? I wonder who knows it!
By the way: clutching from speed 3 to 4 is perfect, backwarts too.

I had a look in the spare parts list 58 and the D605/12 from 1941. I scanned both pairs of pages and marked red what I found concerning the clutch/friction plates. The spare parts list (Ersatzteilliste) 58 is for both, NZ 250 and NZ 350. In the red circle there is said "*Nr. 122304-0 und 122305-0 kommen für NZ 350 je 4 mal zum Einbau" which has to be read that NZ 350 needs the friction plates 4 times, and only the NZ 250 needs the friction plates 3 times. In the later D605/12, concerning only to the NZ 350 there is just said to use 4 friction plates (red circle). The switch is identic both on NZ 250 and NZ 350, there is no alternate part.

The upper picture is from List 58, the lower from D605/12.
