I dont use this anymore...

3 months ago I replaced all the bearings of my s/c.
Last couple of weeks i heard a grinding noise .......

So i dismount the s/c again for the 4th time since i have my s/c.

And when i opened the s/c...i found this:



The left propeller grind to the housing.

What was the cause:

The Sealant is to thin, so the prop goes to deep in the housing and grinds to the side.

So today i have taken some pictures and measurements, so i can make some real gaskets.

Dang man, that sucks.

Oh crap! I bet that sounded nasty.

wow, how did you not hear that wearing through? It had to make some crazy noise / vibration, not to mention that your motor is probably shelled too with all that metal going through the combustion chamber... Damn, this really sucks, I feel for you.

If I were you, I would pull the head off RIGHT NOW and check for any damage in the cylinders, before you even start the car anymore. Those metal shavings could WRECK your engine, not to mention clog up the cat(s). And definatly change your oil.

Are you referring to the sealant for the nose? If so, that wouldn't affect how deep the rotors go into the housing. Typically, bearing problems are what causes the rotors to scrape.

i totally agree. the sealant that you use will have absolutely no affect on that accept for leaks. bearings outta tolerance

[trd4life]

ouch!

[JvR]

Thanks alot for the concerns ...but no, the engine is running Perfect.....scrapings are to smal to make damage.
(engine is running 500 rpm idle with any hik-up)

10.000 km ago i replace every bearing with caremic bearings. I even replaced the needle bearings.
For the closing of s/c i used that sealant i mentioned .

The nose sealant, is no problem at all...it only needs to close...so it will not leaking any oil. But the second one:

This part......:

When the sealant is to thin the rotors wil go deeper in the housing.
When the s/c is heating up the rotors will expand and eventualy it will hit the housing. (we are talking about less of 0.1mm tolerance)

I now have bought paper sealant and i can choose for 0.1mm or 0.8mm (thick)
Anyone knows what size I should use ?

[akora12]

I'm not aware of anyone using a sealant between the rotor assembly and the s/c housing.

Regardless, I still think this is a bearing issue. The ends of the rotors should bottom out in the needle bearings w/o rubbing the inside of the s/c housing. I have no gasket between the rotors and s/c housing, and my rotors don't scrape.

I'm lost here.....

These are new bearings.
When i drop the rotors in the housing i don't have to force it to go in.

After i mount everything i can rotate it, but when i lift it by 0.5mm i can rotate it easy.

Can you explain me, why it must be the bearings?

The rotors should be able to butt all the way to the s/c housing w/o any problems rotating. As I said before, my rotors have no gasket and don't scrape. I can't be sure of your exact problem, but you might have the wrong bearings (i.e. too short) or they may have been installed incorrectly.

Probblay sounded like putting a puppy on top of a meat slicer.

[TxBmbleBee]

yikes you said you installed them yourself, i hope you did it right

[jetbtkng]

if its rubbing its a bearing, or spacer issue, not a gasket issue, thats why it costs $800 to $1000 to rebuild them, very tight tolerances..................
