Gearbox Maintenance

[efwd]

wow, if you weren't a tinkerer Larry, this could have ended up with you landing off field sometime soon. Glad you found that and that scenario was averted.

Larry,

just out of curiosity, any idea how much time the engine with the damaged shaft had on it; or, if it had the rotax recommended mid time overhaul?

[Av8r3400]

The engine has about 350 TT on it. I was going to do the gearbox re-shim when I was assembling the plane but ran out of time. That was another reason for doing this now, I wanted to get that "mid time maintenance" done.

It isn't because of all that extra HP you're carrying around from the Zipper?

-- Just me being jealous of the stupendous climb rate you get.

How about that huge prop as well?? Maybe I'm just being jealous as well. :-) Maybe it doesn't put any more pressure on the gearbox than a heavy 3 blade Warp drive??? Hope you get it sorted out and back in the air soon. JImChuk

I was worried about that during the build so I did the MOI test. The whole hang the prop from a string and swing it back and forth, deal.

My calculations showed something like 4900 cubic meters per lunar rotation or what ever the units are. 6000 is allowable.

Now the 400hp, plus nitrous mega-zipper 912 has nothing to do with it...

Well I hope you get it all fixed up. I do enjoy those Wisconsin videos.
