I can’t remember what the gimbal bearing looked like, but I think the inner portion is pushed in. |
:eek:You're going to need a bigger slide hammer! Those splines are impressive.

Just to check I’m not crazy. Since I have the lower off, if I rotate it and the prop shaft turns 1 revolution, and the shaft that goes up in the upper rotates 1 and almost 1/4, that means I have 1:24 gear ratio,,,,right? If so , I’m surprised I can turn 32p and 30p props. |
Do the upper gears have the same number of teeth? If not then the upper gears will change the ratio also.

Well, since I’m not opening it, I can only count rotations, on a differential, this would be the procedure. Since you say the upper is 16/19, it’s not 1:1, but darn close. |

I guess what nobody is saying is, since the upper is not 1:1 , you can’t figuer out gear ratio by turning the vertical shaft in the lower and count rotations, you need it together as a unit and turn the driveshaft, and count rotations. |
No it can be done, by rotating the lower 10 times. Your rotating 10X because it becomes more obvious, then working with small degrees
As example Upper gears 19/16 = 1.187 Lower gears 15/19 = 0.789 Calculation 1.187/0.789 = 1.504 ratio So rotate and count 1.26 lower 17/18 = 0.944 10X = 9.44 1.35 lower 15/17 = 0.882 10X = 8.82 1.50 lower 15/19 = 0.789 10X = 7.89 |
