Supercharger rebuild??

[shube31]

I have a 2007 and 2008 GTX 215hp Wake machines. Both have had their supercharges rebuilt and ceramic washers replaced at 100hrs with upgraded metal ones. They now both have over 200hrs. I was told by the dealer that it probably would not be necessary to have a rebuild done again at 200hrs because of the washer upgrade. Of course this has been done several years ago. They both have no performance issues and run like they are new. Would you recommend having the supercharges rebuilt again now that I have put over 100hrs on the last rebuild?

Thanks...Shube

The rebuild is recommended at 200 hrs because of the bearings and oil seal, there used to be a 2 year limit but they removed that. So you should be looking at doing it at around 300 hrs if the first was done at 100.

Funny enough, was just talking about this very thing recently. It is still 100 hours.

The clutches aren't the only issue; the bearings need to be replaced.

The supercharger in these engines gets essentially splash oil. This isn't enough to keep the bearings cool spinning at over 40,000 rpm. The bearings have plastic cages, which get brittle over with and with heat.

While the new clutch washers wont explode like the old ceramic ones, they still lose hold which induces more heat.

$100 to anyone who can tell me what is different in the "200 hour" kits from the previous kit (a side from part number). BRP just changed the service interval to help combat bad publicity on the service frequency.

Pretty much what they said I just finished rebuilding a machine that was already on steels so owner didn't worry about it. Bearings went, totally destroyed all parts of the S/C, nothing repairable. Pulled some crap out of crank as well and replaced both oil pumps and all main/rod bearings. It isn't worth the risk, if it just quit working when they go, then who cares but it eats expensive shit when it goes.

Agreed , I change the oil way before the recommended time suggested and I do the supercharger at 100 hrs. Why wait for an expensive failure

JoeZ:

You didn’t include a time interval in your post. After you rebuild a supercharger what is your recommended time interval between rebuilds for someone using their ski less than 50 hrs per year?

They removed the time requirement as far as years, only hours of use now

Don't go more than 4 or 5 years regardless of the hours. I've seen failed supercharger bearings on a Sea-Doo that was 6 years old with only 52 hours on it. Another had only 66 hours. Last week, I rebuilt a supercharger for a customer who bought a 2013 RXP with only 16 hours on it. It wasn't worth the risk for him. Those plastic cages in the bearings get old and brittle and fall apart.

The standard has been 2 years. I agree with @Chester that 4-5 should be fine, however the "corporate" me still says 2 years.

We've seen them go much much longer, especially in boats...but Chester is dead on.
