The info in the download section about crankshaft seals are not correct, in the info there is stated 25x42x7 for the NZ 350, the right dimensions for the NZ 350 crank seals are 25x42x10

@Frank

Many thanks for your input about the NZ350 seals! I have updated the files accordingly. You are absolutely correct, but when I rebuild my motor, the 10mm thick seals were not available, so I used 7mm thick seals and shimmed them accordingly.

Merry Christmas

Hello,

sorry,I do not have pictures. But the gaskets and the bearings, except for the crankshaft, are absolutely standard items. With the description 6203 and 6204 and the measurement of the radial gaskets, you will get the parts in ANY bearing shop.

the bearings for the crankshaft are not available from any bearing shop. I only know two companys who overhaul the crankshafts an who make the bearings. As far as I know, they do not sell the bearings separately. One source might be

Have your crankshaft rebuild by someone who knows exactly what he is doing.

I recommend:

http://www.jbk-moto.de/ ( takes approx. 3 months)

or

http://www.ebenheim.de/eikuma/ (takes up to 10 months)

I don't think that you will be very sucessful in finding a bottom end that just need "cleaning".

Merry Christmas

OK
What about your machine ?
How did you do with your engine ?
Did you change your bearing and seals by new one ?( with a transformation of the crankshaft or other thing)
Or did you "clean" and replace them ?
