AndreiC Posted October 8, 2023 Report Posted October 8, 2023 Hello all, the governor cable on my 1970 M20E looks to be rigged a bit funny. It is not pulling on the arm of the governor in a straight way, and I am not sure it allows the arm to reach both stops. Can someone with a similar engine installation (IO-360) perhaps post some pictures of how the cable is rigged on their plane? The mechanic at my field, who is a very good mechanic but does not work on Mooneys regularly, told me he could fix it if he had some pictures showing how it is supposed to be when it is right. Thanks! Andrei. Quote
EricJ Posted October 8, 2023 Report Posted October 8, 2023 The Illustrated Parts Catalog or Parts Manual for your airplane should have a drawing showing the factory installation orientations, etc. Quote
AndreiC Posted October 8, 2023 Author Report Posted October 8, 2023 Strange. According to the IPC, on a 1970 M20E the prop cable should be coming through the firewall on the pilot's side, and pull on the governor control arm from right to left. (See attached picture.) On my plane the prop cable comes out through the upper part of the firewall on the passenger side, and comes to the governor from above, held by a bracket attached to the upper-passenger side engine mount. Is this a non-standard installation? Could someone maybe confirm? Quote

This might be the prop control version you have… Quote

Could you please perhaps shoot me another picture of the higher part of the governor control cable? The portion that goes from the firewall to the support bracket? Thanks a lot. Quote
PT20J Posted October 10, 2023 Report Posted October 10, 2023 I might replace that ball stud attachment with a rod end. 2 Quote

That picture is from a previous post… Perhaps @chriscalandro or @Skates97 who have installed the ATH-1 prop governors have more detailed pics of the cable routing they can share with you… good luck!

Skates97 Posted October 24, 2023 Report Posted October 24, 2023 Sorry, a very late response to this. Getting good pics requires removal of the top cowl. This past weekend I did an oil change and with the cowl off and oil filter it was wide open for pictures. @Andrei Caldararu 2 Quote
AndreiC Posted October 26, 2023 Author Report Posted October 26, 2023 Thanks @Skates97! This is very helpful. Quote
