On April 4, 2017, Sally & Clarence Davis arrived for a visit. Clarence & Sally had the Michigan stored at their barn in Hobart, Indiana for a year after we purchased the car in 2011 and they helped us move the car from our garage to our work shop in 2013. Sally (Janet’s sister) is also a great grandchild of Michael Fleck, the original owner of our car. Clarence has been a great help in working on the car and has extensive experience with the care & maintenance of very big power plant machinery. He & I commenced work on April 5th, going over the entire differential and drive shaft.
We got the adjustment of the ring & pinion gear to the smoothest operation so far, tightened up the torque tube adjustments of the depth of the pinion, closed up the differential and added the very viscous gear oil.
Maybe that will be the last we need to deal with the differential for a while.
