I think a 1951 NH should have a one piece rear mudguard. Your mudguard and stay look to be for an earlier model.

for future reference the dimensions of the circlips according to my measurements (I measured the bore and groove in the cases): Crankshaft circlips 1443-37: Dia: ~54mm or 1.375" or 1 3/8", Thickness: as posted above 0,03" or ~0,8mm Hello Gui, I think the diameter of the crankcase bea...

I'm missing the circlips for the crankshaft ball bearings 1443-37 and the one for the camshaft bearing 1464-37. Is there a modern alternative? Does anyone have the dimensions? Or alternatively what if I just loctite the outer races to tha cases? Bad idea? Hello Gui, Welcome to the AOMCC Forum! Alth...

Chris, do you mean 3,175 mm? Hi Eero, Yes, 3.175 mm is what I mean. When the motor and sparkplug are hot it is handy to have a spare (cool) plug in one's pocket to make testing the spark a simple matter of pulling off the high tension cable from the hot plug, attaching the cable to the cool plug, p...

OK for 10/15 miles stopped for 10 minutes it wouldn't start Difficulty with hot motor starting suggests a magneto condenser problem. Next time it won't start when hot check to see if you have a good spark. Bring along another spark plug with the gap opened up to an eighth of an inch or so for testi...

should I warm the head and freeze the guides to help fitting Hello Ralph, I have used the heat/cold method for fitting the guides in my iron motor Sq4 and it seems to work OK. Nicholson, in the 3rd edition of his book, just says this on the subject: "Use a good quality heat-resisting jointing ...

Hi Wade,
I have a spare from an incomplete set that you can have. Remind me by PM of your mailing address and I'll send it out to you or next time you're in Montreal make a side trip down here to Sutton and pick it up.

Because the regulator is electronic there will be some sort of device (power transistor) that will first need switching on, so, maybe my dynamo just isn't outputting enough voltage without a field coil in circuit to ever activate it / switch it on? Hi Keith, I remember having an electronic regulato...
