Hi Emlupi, What motor & transmission? There are different sizes.
For sprocket removal with main shaft in place you must have very deep socket. Problem is most deep are not deep enough.
But, if you get 3/4 drive the main shaft fits into the 3/4 square a short ways. So you just don’t push the 3/4 to 1/2 adapter all the way in.
650/750 5 speed is 1-7/8”
650 4 speed is 1-5/8”
500 I don’t know.
Bonneville Shop sells a special dual size 1/2 drive deep socket. It’s 1-7/8 with an insert to fit 1-5/8 also.
I have Sunex 3/4 drive deep impact socket. 6 point. Then you need a 3/4-1/2 adapter.
Shopping on line socket was about $35, adapter $10-15. Be sure it’s 3/4 drive. The 1/2 drive is too short & won’t reach nut. Even my snap-on deep was too short. Again it must be 3/4 drive so main shaft can enter into. Be careful you don’t accidentally get 1/2 drive.
Socket allows use of impact gun, but more importantly a torque wrench
Obviously if you can weld you can cut top off one socket & weld on another or a steel tube spacer.
Kind of puts the $59.95 price of dual socket into perspective. Not a waste of $$ for what you get.
