March 27, 20215 yr While turning the countershaft on my 199 by hand it stops turning once every revolution. If I turn it harder it will rotate. The transmission works as it should although the shifting is a bit notchy. What is the cause the sticky countershaft?
March 28, 20215 yr Author I have fresh gear oil in trans. The 199 sat for 24 years while I was working heavy hours. I did ride it last year a few miles. I wonder if changing the fluid every two rides will fix the problem. I would not want to damage the transmission by riding the bike.

If you rotate it until it binds does it rotate freely the other direction then bind up again in the same spot every time? If you loosen the sprocket nut does it change? Is the shoulder on the sprocket on the inside? How did you come to notice this?
March 30, 20215 yr Author Yes, It rotates freely in both directions and binds in the same spot. I noticed this when I would roll the bike in neutral there would be momentary tension and then release on the chain. I will pull the sprocket tomorrow and let you know about the sprocket nut and shoulder.
March 30, 20215 yr Are you turning it with the chain attached to the rear wheel, if so check that its not the rear brake

April 5, 20215 yr Author I removed the sprocket and the problem still exists. There are shoulders on both sides of the sprocket. To take off the sprocket I bent the washer straight and tapped the nut and the socket with the flat end of a small ball peen hammer. To my surprise when I put the socket and breaker bar on the nut it turned free with no effort. The chain wasn't even on. I was attempting to rock the sprocket back and forth at the bind hoping to loosen what ever is causing this problem. I am going to tighten the nut so I can rock the sprocket at the bind.
April 6, 20215 yr I'd try it without the sprocket to eliminate it. Any "telltale" marks on the sprocket or case ? Edited April 6, 20215 yr by b40rt
