Re: Noticeable vibration at 200+ hours 912iS Sport
by Paul Hamilton » 6 years ago
Yes I just ordered a new gear box that better solve the problem for my airplane. People starting to notice and comment on the vibration. Tired of the gear box hassles/maintenance. No problem/vibration on my pusher trike 912iS.

Wow! Those are some rather large chips! Yes the 893341 gearbox will include the ser# 74000 series “oiler”. I have 50 hours on the new gearbox and it’s smooth as silk. No vibration whatsoever.....
Hopefully good after 500 hours....

is there a typo error in Bobzz's post listing the 4 different Rotax part numbers? the Rotax illustrated parts manual displays 4 part numbers, all starting with 89---- yet bobzz' post shows the 2 p/n for the SPORT as starting with 84---?

Well I ordered the new gear box June 6 2019, told 2 weeks no problem and still July 15 and nothing. The status from CaPower was that it SHOULD be here in another week to them then shipped to me. Vibration is getting pretty bad now I need to keep it out of the mid range 42000 to 4800 RPM. Pretty bad customer service.
