B44 clutch operating rack

Just installed a new clutch in my 1970 B44 however the actuating rack (gear cog) is jammed in the outer timing cover and the lever is not quite in the right position (1 tooth out). The top or the rack has a chip out of it and I wonder if the piece is jammed in the pinion gear. First I thought there might be a lip on the edge of the cover that was preventing it from coming out but that's not the issue. I've tried prying and picking at it but to no avail. I'm wondering about removing the pinion gear from the lever - any comments or suggestions?

The lever unscrews from the pinion left hand thread!

Thanks for that. Coincidentally I just read that on page 109 of St. Rupert's epistle to the ham-fisted. It also explains why the ball bearing is jammed and flattened.

I worry that the correct smaller ball can drop out during clutch adjustment or cable changing.

The problem with the clutch rack was that the pinion gear and rack were so very badly pitted, corroded and rusted that it was jammed. I cleaned, filed, polished and greased them, but was unable to get the ball bearing out (no way will it just fall out). I reassembled with the correct lever angle and the clutch now works smoother than it has for a couple of years. Thanks for your help.
