The Bosch AFR sensor has been replaced since cleaning it did not restore it's function. With no power to the sensor heater, it would read 10, with engine warming up and heater powered on would momentarily read 13 and then go to 15 or higher.
The 2nd ring gear was replaced yesterday. A Dremel cut off wheel cut a slit as deep as possible without nicking the flywheel, then a cold chisel was used to pop/crack the ring. The replacement ring was heated to 450F and the flywheel was chilled in the freezer to prepare for installation. The ring easily dropped into place and shrank in a matter of seconds. A new alternator belt was installed.
LPS2 (no silicone) was used to lubricate control surface hinges.
We'll plan the cowls on and do a taxi test on Sunday or Monday. We'll plan on about 40 knots to finish bedding the brakes.
