Model 7 rods

I think they will be the same as later 88 and 99 rods, whatever they are! I have a spare 99 rod somewhere if no one else comes up with it.

The 500 and 600 had the same rod with 1.5 big ends , the 650/750 had 1.75 big ends.Your book is rubbish!!, Norton did make a few specials for Works racers. There has been talk of perhaps a mystical Nomad with !.75 crank ,But no one has one that I have heard of. No reason you can't have one made, send me 4000 Quid !!. The 600 got its extra capacity from a crank with a bigger throw and bigger Barrel.. The 650 /750 rods wont fit a 7 . The 650/750 Rods with crank will fit in 7 cases if you weld extra room in there for the bigger crank throw. Are you very brave??. A 99/77 crank /rods/barrel set will fit your cases. Simples!!. Dynamo and alternator cranks are different to each other.

For the idly curious, a BSA A7 rod will fit an 88 or 99.

He is confused enough as it is Gordon. Don't mention your 750 model 99.

For the idly curious, are new A7 rods availiable?, are they better than old Norton Rods?.(they do appear to be made from the same forging/stamping).

Just measured the spare 99 rod. 6inch centers.

Possibly a good place to remind anyone going inside a Norton twin engine for the first time... Crankshaft bolt torque is listed at 35 lb.ft. in Haynes also... And should be 25 as noted above.
