T-L repair

This was triggered by part of Dad's 5677A blog. I happened to be dealing with the exact same issue on a 56 Super. On this car the splines on the lever not only twisted but actually broke off--the first time I have encountered this in forty-odd years. Fortunately nothing else was ruined.
Whilst cleaning and checking decided to look at the ball bearing that supports the first stage reduction worm drive. To do that I drill a hole in the 1 1/8" soft plug and flip it out with a punch. The bearing was rusted solid as condensation tends to collect at the top of the gearbox. The shaft was spinning in the inner race.
Replaced the bearing as pictured and Loctited the shaft into the bearing for good measure. Made sure there was a lot of the Moly grease all around the worm and bearing during reassembly.
Once again, flee the temptation to operate your leveler manually. Once it has gone over center and you have lost track of which way it is rotating, the gearbox produces enough torque to destroy itself before the fuse blows. My guess is that they put such a heavy fuse in the circuit so the units would operate in sub-zero temps.
