Hey folks, I am replacing my main gear axle nuts with wheel pant axle nuts.
Does anyone here know the torque specs on the main gear axle nuts ?

Jeff,
It appears that everyone here is assuming you are using tapered roller
bearings. If using a straight precision , non tapered bearing,the
process would be much the same but I suspect not tightening it quite as
tight. Either way, grasp the tire top and bottom or front and back and
check for free play when you wiggle the tire. When you get to point of
no wiggle go to the next castle nut hole for cotter pin. On a self
locking nut with no pin as on the Challenger I go maybe 1/8 turn beyond
"no wiggle". There should be an ever so slight drag on the wheel in
rotation with the tapered bearings.
As for jacking up the plane, I place my floor jack on the bolts that
attach the axle bracket to the bottom of the gear leg. My bracket
attaches to the gear leg with 4 AN4 bolts with the nuts and one or two
rows of threads sticking out the bottom side of the gear leg. I place a
rag on the jack head and use the bolts for a non slip lift point.

get the idea. There is not enough bolt beyond the gear leg to bend the
bolt.
