Number of dynamo gear teeth

Forums

Hello all,

From memory the number of teeth on the steel drive gear for Nortons (non-magdyno models) has 22 teeth, is that correct? I can't seep to find it in writing anywhere. My Lucas books dont give a part number for the gear, neither does my Model 7 parts book.

Thoughts?

Skip, the Dynamo drive gear for my dominator, (now. Sold ) was 23t.

I am pretty sure that the Dynamo drive gear for mag/Dino setup is 22t, my dominator was 1957 99,hope this info is useful to you, Jim.

Yes, Model 7 dynamo gear is 23t. In about 2004 my dad and I had to make one, since I could not buy a correct lucas one anywhere. Well, I now know they are a Norton part D12/1013 not Lucas. Les at Norvil had a batch made and sent me one for testing. They may still have some.

Listed in the 1955 M7 parts book pg 6 item TA/100

Thanks Gents! I missed the part number on the "Plate TA" in my parts book, as it is not shown in its normal place. It does list it as D12/1013.

Les does have some (I ordered two), his part number is:

121013 GEAR - DYNAMO MODELS 7, 88, 99 - ON DYNAMO

Whats uniqe here is not only the 23 teeth, but also the recess on one side for the bolt head & the spacer built into the back.
