This is what you need;
2 bearings: 6002-2rs premium grade ball bearing (15x32mm). You can type in 6002 bearing on eBay. The -rs just means what type of seal and temp range. Don’t get a metal shielded one. The Polaris specs show they use the cheapest bearing. Just make sure the size is 15x32mm. Common uses are for an alternator bearing or wash machine bearing.
1 seal: Polaris part # 3610067. Must get at Polaris dealer or babbits online. I called the manufacture direct and they said they can no longer get it.
1 gasket: Polaris part # 5811627. Get at Polaris dealer or babbits online or make your own.
1 water pump seal installation tool # 2872389. Web site: polaris.spx.com I would recommend this because the seal is very fragile. You need to keep that depth of 8.9mm constant. Sockets and washers will work, but you need to be very steady and very careful. The seal is around $17 the tool is $12. If that seal breaks you'll be buying a new one.
1 water pump belt. Gates 5mm power grip, 90 teeth, 9mm wide. This is a timing belt. I got mine at:
http://kscdirect.com/ecomm/search_results.php?q=93906090 it cost me around $12-14. It is recommended to change the belt as long as you got the recoil housing apart because if it breaks you shut off oil and coolant to the engine.
If you need or want to replace the shaft, the Polaris part # is 5132273. Usually you don't need to replace this. The keyway may look like it is wore ( |\ \| that is a picture), it should be cut straight, but it is usually not. The only thing it does is spin the oil pump. The pump is not centered to the shaft causing it to wear. Again, this is a design flaw. If you put on a new shaft, it will look like this again. So if it is not more than half way rounded, I see no need to replace it, but that is your choice.
The only other thing you need is rtv sealant, and antisieze (put those on the bolts that hold the housing. steel bolts and a cast aluminum housing is a good recipe to snap off the bolts. Buy it! It’s cheap) and antifreeze.
1. Take pipe off and the y-pipe
2. Take recoil housing off
3. Lift front end of sled
4. Disconnect hoses
5. Open up water pump housing
6. Take impeller off
7. Push (don't wreck the threads) the shaft out of housing. THE SHAFT AND THE BEARINGS SLIDE OUT TOWARD THE THORATTLE SIDE (not brake side).
8. take bearing off replace (use a press or be careful) everything is just pressed on.
9. make sure the seal is out and the surface is clean.
10. Tap lightly the bearings and shaft back into the housing (lightly coat the bearings and housing so it slides easier).
11. Use wood or something to hold the shaft into the housing (brace it, because you are tapping the seal in from the other side.
12. Lube the shaft lightly with rtv, then carefully place the seal onto the shaft straight, then use the tool and carefully tap the seal down the shaft (keep the seal straight) until the seal seats into the housing.
13. Put the washer and impeller back on.
14. Reassemble and you should be all set.
15. Next project, put and edge skid in and 2" handle bar risers. You’ll have a great trail sled. The edge skid does wonders for the genII. I did this and it was night and day difference.
