Water pumps aren't rebuildable. They're also expensive. And the single most common problem I've seen is that the inner oil seal works loose and the pump leaks oil out the weephole. As long as there's no radial or axial play in the shaft, and it's not leaking water, the pump is completely repairable.
first, clean the pump well. Brakeclean is a favorite. Remove the inner seal, the circlip, and the seal for the inner bearing. a small pick works well for removing the seal. Pack the bearing with some wheel bearing grease, reinstall the bearing seal and circlip. Now clean all the grease from the inner bore. A couple Qtips and some brakeclean does a good job. Install a new kawasaki seal # 92049-1416 with some locktite wiped around it's outer diameter to help it stay intact. Be sure you install it so that you're looking at the inner lip of the seal when you're done (flat side toward bearing). Tap it down squarely until it's fully seated. Let the locktite set up, then reinstall the pump. Easy to do, and will save about 175.00 on a new pump - HTH, Steve

I've seen two versions of this pump. One has a groove machined onto the impeller shaft, which serves as the inner bearing race. This type I would think is not rebuildable.
The other version, shown in Sig's links, is rebuildable. The problem is finding the mechanical seal, which apparently GPz zone now carries. Thanks Sig!

thanks Sig, I have tried to press a couple pumps apart but the housings cracked before the shaft moved. I'll try again. Rebuilding would be a whole lot less expensive than buying new - steve

Hello Steve in Sunny Fla

There exist two diameters mechanical seal therefore necessary to remove the pump to check if the axis is not too rusty and measure the le seal mechanical
After request from the seller I ordered the mechanical seal for water pump

Price: 27£

Hi Richard
The measurement is the widest point of the seal, not the diameter of the pump.
Measure the lip on the seal; it will be either 32 or 35mm.
Best wishes
Model water pump number: 990 – 1 KAWASAKI ZG 1000 1986 A1

So before I pull my hair out looking for the seals, approximately how much does it cost to ship to the USA? I have the clip style shaft and tools to press the bearings in.
