Today I helped a friend replace the seals on the draft control shaft on his old model 4020. In order to get the shaft back in through the notch in the draft control arm we had to play around with the level on the side of the rockshaft control. This lever has 3 positions, it was always in the middle position, to get the draft control arm free we had to move it to the bottom postion.
Now the arms will only lift with that lever in the bottom position and only lift part way.
Any ideas what went wrong or how I can correct the situation? I'm not sure what that lever is. The dealer I picked up the parts, they said I might have to play with it to get the shaft back in. Until I move that lever there was pressure on the arm and the shaft wouldn't line up with the holes on the other side.
It is also possible the hitch was set up due to my friend doesn't use the hitch that much. Had a hard time getting the hitch to drop when I started.
