The difference in the weight is the 1st thing that struck me , wow . 10 ft'r is HEAVY , oh , that's why most of you guy's have gin poles , fork lift , overhead chain fall , cherry picker , etc. to lift the load .

They are much heavier the bigger they get and I’d imagine your 10’ #12 is heavier than my 10’ #15 with the #12 having two pinions and two bull gears. I can pick up most 8’ gearboxes, but I use the tractor frontend loader for the 10’ ones or bigger.

Mike, the guiderod that screws in above that race screws down on it to hold it tight. Make sure the race is all the way in before tightening that guiderod down.

Heat, tapping, and patience. They just slide on.
