I'm new to Norton's and will be refitting the head and barrel on my 750 soon.
I'm concerned about tightening the barrel and head to the correct torque settings.
The problem I see is with access to the barrel base nuts and the sleeve nuts for the head, as getting a socket and torque wrench on these looks impossible without some kind of adapter.
I'm sure most of you have overcome this, so any help would be gratefully appreciated.
Cheers
Robin

Absolutely - this is exactly how I didit on my Mk 3 850 and never had a problem.

It's reasonably simple to use a torque wrench on the cylinder base nuts of a Commando. Obtain a 1/4 whitworth combination spanner (ring spanner at one end and open ended at the other) and grind or file the ring down until it fits over the base nuts without fouling any part of the barrels. You will fing a 1/2 inch square drive torque wrench will fit the open ended jaws. Provided you set the angle between the torque wrench and the combination spanner at 90 degrees you will be applying the torque set on the torque wrench to the nut. Be careful not to apply any angular assistance to the spanner when supporting it in position. I've just used this method in the last week on my 750 Commando. With a little care you can use it on the sleeve nuts on the head as well. The 90 degree figure is the important part and the length of the spanner is irrelavent.

Not sure about the spelling of irrelavent (Twice now or maybe three times)
