DRZ400 Water Pump Rebuild + Coolant Leak Fix

Rebuilding my DRZ400 water pump which has a slightly leaky oil seal, and possibly a very minimal coolant leak.

For an actual how-to guide, see my writeup here: https://thumpertalk.com/forums/topic/1355345-drz400-water-pump-rebuild-tutorial-video-pics

This is not exactly a how-to video, but it can be useful. If you are using this video as a reference, be sure to replace the side cover gasket which is not shown in my video. Other things not shown in my video which should be done include: greasing the impeller rod on reassembly when inserting it into the pump assembly (and try not to remove it after inserting it because the slit for the e-clip is very sharp and may damage the oil seal); putting a little grease on the o-rings (and "b-ring" as I call it) so they stick to the pump assembly; and I torque all the side cover bolts to 84 in/lbs, although that's just my preference. Don't use loctite on anything. Also: If you use a blind bearing puller for the two bearings, use the 10mm fitting (not the 8mm which I use in the video). And then obviously don't forget to refill with oil and coolant. Wait 24 hours before running the engine if you adhered the coolant seal with RTV silicone.
