hinook mechanics, keep your aircraft’s aft engine mount link (dog bone) with
the airframe whenever an engine is removed. If you don’t, you’ll have to order a
new one before installing the engine.
When an engine is removed, the dog bone is often removed, too, and often
misplaced. Each engine has its own dog bone, and each one is specifically
adjusted to align that engine’s drive shaft with its combining transmission.
The dog bone has its own storage place on the outside of the airframe, just
below and to the right of the engine.
After engine removal, put the dog bone there, so that its adjustment stays
intact. You mount the dog bone to the airframe with the same hardware used to
attach it from the engine mount to the engine.
