Eprops on Rotax 912 fitting tool

[Blueadventures]

I have recently purchased this adaptor tool for torquing the flange nuts used for Eprops and some other propeller brands that are not attached using the usual drive lugs on the Rotax flanges.  Will be handy. Just need to do calculation for reduced Nm setting.

I believe... (CHECK IT TO A RELIABLE VERIFIABLE SOURCE) that if it is at 90 degrees to your torque wrench, no calculation is needed. Set and use.

I have one of those things but can't for the life of me recall what they are called.

Agree and have a full set, for e-props and warp drive the ring end 13mm adaptor will be great.  For the other question they are torque adaptors or 'Dog Bone' in some circles.

Agree, I have crows foot for certain deep narrow access needs.  Used sockets and allen key drives as best grip on fastenings for prop torque.  Bought the dog bone (E-Props prop hub nuts are torqued at rear of flange) and yet to use it.  It will be good for the tight area between the rear of the gear box prop mount flange and the front bearing body area of the Rotax 912 gear box.   Anyone with props mounted to the Rotax drive lugs inserted into the flange will be tightening props from the from and won't need this tool (examples Bolly, DUC, etc)

Have you torqued a Hartzell prop? Open end only.

What Torque are we speaking of? Any mechanic worthy of the name knows the limits of an open end spanner.  Nev
