Lycoming R680 - Part 2 - Cylinder Replacement

Описание: In section two, Steve walks through the cylinder replacement process. Beginning with the tools required and the positioning of the piston head in the cylinder that is being replaced. Cylinder number seven is the master rod cylinder and should be the last off and first back on if removing all cylinders. It also needs to not be disturbed as it could allow other pistons to travel past their bottom position and piston rings would spring out in the case locking the pistons in place.

Steve follows up with the order of removing components starting with the front of the cylinder. After this, Steve shows the areas where the intake, exhaust and baffles need to be loosened and removed. The process to get a single cylinder off does require a separate set of hands to make sure the link rod and piston don't come into contact with the side of the case as the cylinder is lifted off the engine.
