I have a 912S and I had the clutch upgraded to the slipper clutch. I had the 

clutch done by a dealer but I had to remove and install the gear box myself. 

After I changed the clutch I ran the engine and it all seemed fine, no leaks 

and sounded good. Yesterday I taxied out on the water and took a few short 

runs just to check that all was well. Oil pressure was good, all temps were 

within limits. When I shut off the engine I could hear a dry sound. It 

appeared to be coming from the gearbox. I hand proped it and could hear the 

same sound almost a squeeking sound from the same area. Pulled the plugs to 

check them they were all fine (left them out) and after when the engine 

cooled a bit I hand proped it again and it sound normal. Is my gear box not 

getting oil? Or is something else wrong.  Any ideas

It is not a good sound. It is the kind of sound that makes one happy to be 

on the ground and not in the air while it is happening.

Maybe a bearing or something was too tight when the slipper parts were 

installed and when the engine gets hot it is too tight.

The slipper clutch makes a squeeky noise when you stop the engine.

They are all like that.

When I first started to hear the noise I was idling down as I was pulling 

into the dock, so the engine was still running at the time. After I shut 

down and turned the prop by hand I could still hear the noise. After the 

engine cooled down the sounds were normal. Does your do this too?

I think it supposed to squeek only when you stop the engine.

Mine is quiet when i turn the prop by hand.

If your carbs are unbalanced it could possibly squeek a little at low rpm but thats just a guess.

Shane, if you have the capability, tools, and time, you might dismantle it 

to do some exploratory surgery.  If there is a problem it should be evident 

and it's just a matter of making a repair.  If you don't find anything wrong 

and you're satisfied that all is well, then your future flights may be with 

less worry.

It is the same oil.

  

 Tied the plane down today and fired it up. Warmed it up  first for about 5 min or so and then started running at higher RPMs. Finished at  5200 for two minuets. Sounded fine. Then ran it around 2K for a few  minents and shut it down. Shut down was normal. I didn't get it as hot as  yesterday, never seem to be able to get the temp up high when on the  ground. So I don't know maybe I will try it again on the water tommorrow.  I am going to check that magnitic plug on the side of  the gear case above the oil filter first just to see how it looks  first though.

I thought I would provide a up-date to my earlier problem. I have flown 4 

times since I first wrote and have had no further issues with the noisy 

clutch. One thing I have noted is that the engine doesn't normally run as 

hot as it did that time when I thought I had a problem. It runs about 20 to 

30 degrees cooler while in flight. So perhaps that was all it was, the 

clutch doesn't like the upper limits of the operating temp.

So all is good, engine runs fine.
