Re: NH350 piston ring size.

Dave,
Thank you for that information. I may have found a supplier but if that falls through I will contact Cox and Turner.

NH350 piston ring size.

I broke a piston ring re-fitting the barrel on my 1956 NH350 today. I see that Drags sell piston ring sets but they stock standard/ 20/40 and 60 oversize. My piston has +30 clearly stamped on the crown. Do I need to find +30 rings if they exist?
Many thanks, Dennis

Re: Find bike registration details from a frame number

Roger,
Many thanks for looking. I assume that you or someone at the club entered my name against the frame number when i posted a topic asking what year the frame was made so we come full circle😁

Re: NH350 camshaft locking up on assembly.

Will, good point about the crankcase bush. If it is the camshaft length there is not much I can do about that since I have no access to a lathe. The thick gasket provide a small amount of end float for the shaft sufficient to give free rotation of the shaft so I will go with that for now.

Re: NH350 camshaft locking up on assembly.

Will, Thank you for your reply. The camshaft bushes line up and the shaft moves freely so I do not think it is a problem with the camshaft alignment in the bushes. I tried another inner timing case that I have, an unserviceable one, with the same result. I only mentioned the profile of the cam for i...

Re: Find bike registration details from a frame number

Roger, nice one! I read with interest the topic in the Ariel section about factory despatch records and your endeavours to link that to frame numbers. Given that some bikes were pre-registered by the dealers it might be the case that my 1956 NH350 was pre-registered. If you have the time would you p...

NH350 camshaft locking up on assembly.

I am rebuilding a 1956 NH350 engine from used parts. I bought a camshaft and inner timing cover from an earlier model (no dowel holes). The camshaft locks up when I tighten the case screws unless I use a vey thick homemade gasket. Is that acceptable or is there an underlying problem? The gasket is m...

Re: Find bike registration details from a frame number

This thread is quite long now so for information I do not know the original registration. Regarding contacting the registration authority archives, I am some way off completing the restoration so I will wait until the bike is complete in case I need to re-register it with the help of the club. I ask...
