Looks like I'm having the a problem with my 2008 Challenger 230 SE 430hp with about 50 hours on it.
One engine only revs to 6500 while the other is at 8000. I took off the hoses on the Super Chargers and one of the blades spins by hand and the other doesn't.
Is that what happens when the washers go or is there another problem? My "dealer" has changed my oil twice and I mentioned that it could not be synthetic. He said that it was ok now and used a "blend" , whatever that is.
I've put about 4 hours on it since I noticed a difference in the operation. Only once did I open the throttle all the way to see what would happen. Hope that didn't cause more problems.
How difficult is it to replace the washers?
Thanks for any info.
EDIT: Whoops. Looks like I missed %90 of this thread, and you've gotten it fixed. That's awesome!
Hi Dave. Sounds like your ceramic shims might have failed as you guessed - especially if you can just turn the tubine blades by hand like that. You really shouldn't run the motor that much more now that you know something is wrong. Bare minimum that oil needs to be changed and filter too.
The shims themselves aren't just replaced alone. BRP offers a shaft repair kit that contains new bearings and a gear and several other parts needed to do a complete rebuild on the blower. You should probably have the other one done at the same time. The new kit will have steel washers with a moly coating instead of ceramic shims.
Good luck, hope this helps some.
