Turbomeca Astazou .

This engine was purchased along with the propeller hub and several spare bits and pieces. The intention was to get it operational with a propeller installed. However unfortunately finding the correct parts such as the prop shaft proved very time consuming despite being able to visit some wide and unusual sources that actually operate the engine. (the engine must have its prop shaft or a complicated test adaptor installed as there are several seals on it and internal galleries for lubrication of the front gearbox brg and actuation of the prop pitch change ram, a splined adaptor and the front gearbox bearing itself) Digging around for all of this took weeks and weeks and ultimately proved beyond my patience level and available schedule at the time so after a great deal of mulling I let it go. It eventually found its way onto a wing and to my great pleasure I have since seen it run installed with a prop fitted.

The engine systems looked a lot more complicated than they were. It was all quite straight forward, just different in places that's all.
