Rotax 912 ULS - Fretted CrankCase
in 912 / 914 Technical Questions
12 years ago
Hello
I am after some information please. I have a Rotax 912 ULS (S/N 5645095) that was new in 2005 and has been in an Alpi Pioneer 200 since new. It currently has 750 hrs on it (I have owned since 600). We have recently found it has been hard to turn over and after finding the thread on here regarding this we slackened off the number 2 cyl studs and sure enough it freed up indicating a fretted crankcase.
Today we removed the engine from the aircraft and have totally stripped the motor, which has confirmed fretting in several areas between the crankcase halves and there is significant wear on the white metal bearings all of which was pretty much as outlined on here and what we didn't want to see but were expecting.
What I would like to know is if Rotax provide any assistance on this issue (replacement parts etc)?? There would appear to be a serious design flaw with this older style crankcase (hence the newer design) and it seems only right that a company such as Rotax should standby there product. The rest of the engine is spotless and the pistons, liners, and crank are in fantastic condition. Its just the fretted crankcase and associated clearance loss in the crankshaft journals.
Basically I need a new crankcase, bearings, seals, bolts etc and to move everything over and I will be up and running again. Unfortunitely I am in New Zealand and parts are going to have to come ex United States. If Rotax are not standing by their product, can you please advise a good company to deal with in the United States that can provide me with the replacement parts??
Does anyone have an email address for Rotax Aircraft Engines?
Thanks,
Jonathan
