parts differences- updated 11. july.

[svenn]

Thought I would post som pics of som diffferences I have noticed on some parts I have. I would guess it was changes made througout the production period due to evaluation and experiences from the different parts. Perhaps someone can shed a light to this..why many parts have differenrt parts number ending... -0 -1 -2 etc..

Is there a system of the endings? I have 1939 model 250 fitted with some parts ending on -2... Would that be version 3 of the parts, after -0 and -1?

Part # 122546 and 122547-Zwischenstück - difference in casting on underside of head for spring holder.

Part # 122546-2



Part # 122546-0




Part # 122547-2



Part # 122547-0



Klemmkopf- part #122660
Not sure which ending on part number, but different in the section to tighten around the main fork shaft. No cut out on one (red) version.




Oberer Gelenkhebel - part # 122656
Different in casting on the underside. The inner rib on each side is more narrow on the red version, not so easy to spot on the pic Not sure which ending on partnumber. Could not find the number.




Part # 122526 Fussraste
Have number on one of them.. Will check asap.
Difference in casting ( One has been straightened at some time)

Part# 122526-1


Part# 122583-0

Hi Svenn,

I think you have mixed up the pictures. Instead of sending pictures from the "Zwischenstück" in version -1 and -2, you postedtd only the pictures from the -2 version?

Anyway, what I can tell you is, that for the "Zwischenstück" the change from Version -1 to -2 was made very early in the beginning of the production of the civilian NZ350/250. I have no idea what this change incorparated (maybe you can post some pictures ? ).
The change from -2 to -3 was made in 1943 when the bolt which attaches the footpegs to the frame was enlarged from the previous 10mm to 12mm diameter. This change asked for a "Zwischenstück" with bigger mounting holes. I can only guess that unter rough conditions during the war, the footpeg bolts simply were not strong enough to carry a fully equipped soldier

Best regards

Hi Thomas!

The pics are correct, but I just haven't posted the other versions yet..Will post them were I have written- "pics coming soon". Will try to get some pics today!!¨

Thanks for the info about the Zwischenstück. Allways nice to learn sometechnical history.

[thomas591]

...yes now I see

Sorry, I think should be more observant...

HI Svenn,

from the parts-manuals I was able to identify the following different footpegs:

1. From partslist 58: 122526-1

2. From partslist D605-12 1941: 122583-0
No idea about the differnce to 1.

3. From partslist D605-12 1944: 122583-1
Now with M8 thread in the shank to attach an M8 bolt with big flatwasher to stop the footpeg rubber from slipping of the shank at heavy use. Funny, the change from M10 to M12 of the footpeg attaching bolt does not result in a new footpeg with 12mm mounting hole. Maybe it was expected from the workshop to take a drill and enlarge the 10mm hole to 12mm! ...Times are changing..If one would do this to a sparepart today, the guarantee for the part would be void with the first turn of the drill.

regards

Hi!

I have updated the first thread with the numbers you provided Thomas.

Hope I got i correct.

So from what I understand, the footpegs changed parts number at some stage, 122526 - 122583 ? Both the pegs on the pics have the same diameter on the hole for the mounting bolt.

Hi Svenn,

if you look at the pictures of my bike in the owners section, you can see the the later footpeg with the M8-Bolt and washer.

Regards

Nice bike you have Thomas.

Do you have any info on rear footpegs? I have two different types on my bike.

Svenn

[thomas591]

Hello again Svenn,

as far as I know (I know that I dont know anything..Plato)there are three types of footpegs.

1. From the manufacturer "Blau".

This is shown below and was used from the beginning until 1943.





2. Used from 1943 on the NZ350/1943 and also on the NZ350-1. See picture below:




3. The third type is similar to the 2. type but the part were the rubber is mounted onto, is made out of steel tubing instead of solid steel. I guess that this change took place in late 1944 to save again some material. Unfortunately I do not have a picture of this footpeg available.

I would appreciate if you could send me some pictures of the footpegs you have.

Regards


Thomas

Here are pics of the two types-- I doubt any of them are original...Nowhere near the pics Thomas has posted. The first one has a too small mounting bolt. The hole on the bike had a home made bushing..

...ups!......
..one picture.....( sorry for my mistake )

[maciek gorski]

.... and one more interesting mistery ....
See pictures below. I've got two upper parts of front suspension.
I'm 100% sure that parts are of NZ's origin, but ......
.... what's year/version of motorcycle?????
Is anybody who has any idea?????

[svenn]

Here are another difference I have noticed: Note the height difference on the height on the center piece. Other from that they are identical as far as I can see.





The parts list claims on partnumber 122874 for both the 250 and 350, so perhaps the last one is for a NZ500??

No partnumber on the parts.
