is the 750sx pump the same at the sxr800? do they use the same bearings?

I have a pump in my SXR800 and its stamped on the side JS750B. I have gotten new bearings for my pump but they don't seem to fit properly. they seem to be to wide. I can get them in but there is no room for the seals? They are definately the right bearings as they are Kawasaki OEM parts for my ski, not a cheapie aftermarket replacement kit. I'm not sure if someone swapped out the pump for a 750 pump at any time before I got the ski. what do you think??
