This is the planet carrier out of an P&W R1340 650 HP engine I think.
Truly amazing that this relatively small planetary gear box
can transmit 650 HP from a 1320 cubic inch engine. Them are some
serious torque pulses :-)

How big is this set?  Weight?
Chris C.

I would guess about 12 inches in diameter and it probably weighs,
as a real wild ass guess 50 pounds ring gear and all.

Note the straight cut gears. No end thrust!

Good idea for a high power  20B Chris. Tried and true and bullet proof.
Relatively cheap too, prop shaft and all. A real bargain.
