What are people using to remove the sprocket retaining nut on the gearbox shaft?
It needs a very deep (3") socket and I am having trouble finding one that deep.
Also, I measure the nut at 1-1/2 inches, but the spec on OB is 1-1/4".
Suggestions?

YES! Knew it was out there someplace. Love spending big $ for a one-time tool. :roll:
Wish I knew a local truck mechanic!
 
I took a 1-1/2' deep socket and cut it in half (Pep Boys <$10.00) then welded in a piece of black pipe I had in the garage. Made it deep enough to fit over the shaft. It also works on the large drain plug on my MKIII.

Hi

I brought a box spanner for about $12 a few years back now. My mate welded a plate into the other end to take a socket wrench.

I sacrificed 2 $10 sockets to make one priceless one. On the end of a impact wrench it is just a matter of holding the sprocket in place with a rag and giving it the gun. Reverse of course (left hand thread).

what should the tightening torque be in psi when putting a new sprocket on with a rattle air gun?

Not very tight. The nut will split if you hit it with an impact. Jim
 
Mine's a creation of 1" bar stock. Cut into 6 pieces of 5 1/2 ". The big nut itself was placed inside for internal support/correct positioning and the pieces wrapped once around to hold in place. Then spot welds to hold together ,then the nut tapped out. Then more final welds along the lenghts. Then 2 recesses were cut into one end to drop into place the 7 " piece of 5/8 solid round stock which was welded into place as a tightening/striking handle. Splatter ground off. Works well ,remember the big LH nut itself has beveled corners on one side ,this side mates up with the drive sprocket itself. A fun mini-project I recall.
 
I just got a 1.5" wrench :| It was like $12 at my local version of harbour freight. I also hold it perpendicular to the frame rail and use a fishing scale right above the open end for torquing. The wrench I have is 14" long from the nut centre line to that point so I only have to pull with 60lbs of force on the fishing scale, if pulling perpendicular to the wrench

Works if you take the outer primary cover off and hold the brake, have had zero problems with this method.
 
Fred / Old Britts it so good to us - with information and parts!

Local super-mechanic-engineer dude Tom Volkman fabricates the needed tool. :mrgreen:

This is a nut removal thread not a nut install thread. Anyhow, the monster socket on the end of a torque wrench is also quite handy. 80 ft lb ish. I will get it close to 80 ft lb then back off slightly if needed to fit the retainer ring. I think torque number are suggested limits and not simply suggested.

if $32 bucks is big time bucks for a Norton repair - you haven't had your bike a very long time! :shock:

I laugh when some forum member says he's cheap, as in frugal. If you are cheap you damn sure shouldn't own a Norton.

I would imagine Jim Comstock is well aware of cheaper sockets. His OTC suggestion is, no doubt, in keeping with his standards of quality.
