Brief Description: Fit Alternator, Stby Alt, Prop Govnr
Today while Paul did some more internal work, Dad and I fit the Alternator, Standby Alternator and the Propellor Governor to the engine.
This was a temporary fittment to see what screws/bolts etc.. was used and whatlittle things we were missing.
All seemed to go well, however, I cant seem to get anyone to tell me the torque settings for the engines studs so that I can tighten these up and mark them off as complete with some torque seal.
I will just keep waiting on that. Once I have some figures I will complete the torquing and refit the engine ready for baffling, wiring and sensor fitting.
I have been a little concerned about this as I have no clear instructions on the torque settings associate with the studs on the engine.
The VANS community has only really refered me to the Lycoming maintenance manual which is a little vague on the torque settings. The standard settings seem way to high and the stud settings way to low.
I refered to my brother who used to work for the default Airline Ansett Australia. His comment was that according to Boeing, they used to use the PT rule........"Pretty Tight" and then if there was any doubt, it would be either lock wired or split pinned. If there was no lockwire or split pin hole and it was deemed a potential issue.... a hole was drilled into the exposed section of the bolt and a split pin or lockwire applied.
I may well complete the same process just to make sure I am happy there are no future issues. Need to think about this one.....
