Interesting.
Very apparent the Charger was breaking loose on torque. I'm now seeing 199 hours on the ski so it's time. Hope they didn't do too much damage riding the ski like this. Order me a WSM kit from Bay Area Powersports. Gonna pull the Charger and rebuild it that way... we'll be good to go. If I decide to keep this one I'll check the torque setting yearly.I did some web research on bearings that I posted on the Seadoo Facebook owners page. I recently installed a kit from SBT which came with koyo bearings.After riding the 2009 RXT... the Supercharger needs attention. These engines talk to you I tell ya.
I wonder if these bearings have a degree of loosness due to the high RPM and environment? Even the same bearing number can be different internally. We had to order special bearings for our 4 stage 350hp blowers that ran 24/7. The bearing was the same size but had a greater loosness than a regular bearing. Sounded crazy to us 35 years ago.
Have to agree the Supercharger system is a crap design. On the RPM I've seen above 8k RPM so that's 50,000 rpm.
There will be pictures. The previous owner told me I have to do something with the floating suspension to remove the supercharger and I've read that some people can't remove the supercharger without removing the jet pump. Typical for me... always a extra stuff to do.
Well, it saves me from replying to a new thread so I get the notifications. It don’t take much to keep me happy, some coffee, smokes, a Seadoo or 12, a few snowmobiles, some good Seadoo forum threads and I’m good,If that's all it takes to make you happy my brother... it's done.
I never click any of those buttons.
Yes, you are correct based on what I've read..https://bywbbearing.com/bearing-clearance-everything-you-need-to-know/. There are also hybrid bearings, ceramic/metal that you get in 6200 series. I considered getting a pair of those and seeing how they work out. Turbos use ceramic bearings, and it would seem that they might have a higher reliability. From what I've read they have a higher speed rating, due to thermal and material properties that are not subject to deformation. Not sure I want to risk damage if they don't work out. I was working with some engineers and testers from Pratt & Whitney back in the 90s and they told me that they had experimented with ceramic turbine blades for the same reason. However, they found out that the blades would absorb fuel on wet starts, and explode once the flame lit so abandoned the technology.I wonder if these bearings have a degree of loosness due to the high RPM and environment?

Shooting from the hip, I believe the failures are due to impurities in the airflow, and worn pieces of the washers getting into the bearings. I think maintaining the proper torque might make the supercharge last longer but if you are bringing it to Seadoo the adjustment would cost too much to be worth while in savings. For a mechanical owner... it might make a big difference. Good Stuff but for most people, they don't have the tools or knowledge to pursue it. You are not going wrong with better bearings.
Both my 2015 and 2016 skis are suspension skis, and although I've only owned them a couple years have taken the upper deck off several times. It's not too hard once you get used to it, first time getting some of the fasteners out is a bitch if they are corroded. I coat them with copper Permatex anti-seize for easy removal next go around. It helps to have an overhead crane or engine lift, you can get the supercharger out just by disconnecting the rear hinge and removing the engine cover. Not much space in there though, and getting the cover out the back is a challenge. If you take the entire assembly off, the handlebar steering cable and 24 pin connector need to be disconnected from the handlebars. I use two 1x3s to support the front suspension deck attachments. If you don't, you risk tearing a hole in the bellows.If that's all it takes to make you happy my brother... it's done.
Wow that's great information. Sounds like a real pain in the azz for sure.
Just curious, how much would a shop charge for the supercharger rebuild and install on the suspension ski? I'm not paying... but I think the guy that sold the ski sold it for this reason. It's time. I was curious about trying a 4-stroke so I didn't do too bad for $2500.
There is a guy I found on Ebay that lives in Florida. He comes highly recommended and I talked with him about it. I had already ordered the WSM parts kit that has the wrenches. This guy will also just change the torque washers if you like but for the money and time it just doesn't make sense to me. He said if I send him the parts he'll rebuild it for $130 which is worth it but I'd have to tack on shipping to and from. I like the adventure.
I want to know what Seadoo Charges.
Me too, I might call on Tuesday.
