Super charger rebuild question - metals washers?

[nateccnn]

I got the rebuild kit from Amazon with a Sea Doo part number 881 102. I disassembled the SC. Found what looks to me like metal washers with a brass color to them. They were worn and had a ridge on the inner ring. The new washer have a coating on them makes me think they look more ceramic rough coat. Or is that just a coating that eventually wears off. Did I somehow buy the wrong rebuild kit?

Those are metal washers. They are the newest you can get. Are you rebuilding yourself? Did you purchase a tool kit necessary to do this?

I got the cheap tools from eBay. 45 bucks for a bag of tools. Last weekend I removed the superchargers and put one in the vice and tried to remove the first shaft nut and the retaining wrench folded like a piece of tin foil. Monday morning I ordered a new retaining wrench made by BRP. Worked like a charm last night. I will say that the 4 pin tool for removing the bearing retainer plate does not quite fit...but a little influence from my BFH made it work.

45 bucks plus the 55 for the new retaining key, so for $100 I own the necessary tools. And I'll probably never use them again. LOL

So what was the total spend on the tools and the kit?

 

[nateccnn]

Lube $39.95
Rebuild Kits $359 x2 =718
Shop M<anual $26.97
BRP Retaining Key $51.99
Crappy tools $59.95

Grand Total $896.86

Bottle of Old Vine Zinfindale $30 = $926.86

PWC Muscle would have cost $870 for both. But...they do not offer the Old Vine Zin. That was the deal breaker for me.

I thought of another benefit if me doing this job...besides the therapy. Cuz clearly there is no financial benefit to doing it yourself. Hopefully the next person that contemplates doing the job will stumble across this thread and see my costs and check that box off their list of concerns. The cheapest way to do this job is to send it to a professional. If you add in the cost of shipping it to the professional, it takes two SC rebuilds just to break even. On the third rebuild I'll save a hundred bucks.

Now do the math on how long it will take to get to the third rebuild. My machines are ten years old and have a hundred miles. At the rate of usage it will be 20 years before I do the third and fourth rebuild.

Now...I do anticipate putting more hours on than the previous owner. But after looking at over 15 different skis last couple months in search of the skis, it's pretty average use to go 10-15 hours per year. I bet states like Florida have a higher rate of usage but in Nevada that's pretty common.

Well...enough chatter...I have one more SC to rebuild. I better get to it.

And...done. how long g did it take? 2.5 hours with a lot of interruptions from work.

I have only done a few, & my fourth will be soon. The mistake I made the first time is I accidentally pushed the shaft into the impeller side bearing "Without" using the support tool to insure the shaft presses against the inner race only. I did cool the drive side bearing & heated the housing so that fell tougher easily, but after realizing how I basically pushed the impeller side of the shaft against the ball bearings & possibly dinged the races, I pulled it back apart & ordered a second set of bearings. Of coarse taking it back apart compromises both bearings. Ooops. So, my first rebuild was $60 more than you spent. (and a little frustration at myself)

Knowing now how easy it can be to rebuild them incorrectly, & seeing first hand the carnage that happens when some SC pieces fall into the PTO side of the case (aka the meat grinder side) I will never take the super chargers lightly. I also would never buy a rebuilt one either, unless it was done by somebody I knew, so I had comfort that they were using the right parts & putting it together correctly.

The second one I did the inner race slid over the shaft pretty easily, so might not have mattered on that one.
First one was pretty snug. Just such a small bearing with such a big responsibilty to take any chances imo
