2nd time around on water pump rebuild

This is the second time i have rebuilt my water pump, machine is a 2003 700 sportsman. First time i put the ceramic/rubber washer on wrong, lesson learned on that, but my question is every kit I buy comes with a bearing for the water pump shaft, how do you get it tore down that far to put that in? I have the magneto cover off (i think thats what it is called), there is a few gears behind it anyways, removed that cover to put the oil seal on the water pump, assuming the bearing goes behind one of the gears? Dont know if its someting that should be replaced or not....but i have two of em now so id like to be able to replace them if its is reccomended...Thanks

2013 sportsman 800 EFI error code 51

Hey all, I bought my bike used from a guy and only had 45 hrs on it. After using it for a couple weekends the one weekend it wouldn't start. I put it on a charger then started up fine. Now I go to use it this weekend and no start again. I bought a new battery and the thing still won't start. I just keep getting a clicking sound.
The error code is 51 but I've traced almost everything and cleaned all connections.

Anyone have any thoughts?

Thanks,
Tyler

Oil Filter Drip

Before ride Saturday I checked oil and noticed it was low, about 1/4 of one quart. It had a slow drip from bottom of filter. So to be safe I decided to drain and change oil/filter. When removing filter it seemed as though it had about 1/8 turn before it was loose. Manual says tighten till gasket touches then 3/4 turn more. That seems like not enough so when I did my 570 and sons 450HO I tightened a bit more. No leaks on 450. Ran it after oil change today, all seems well. Just wondering what others do as far as tightening filter and or anyone ever have similar experience. I’ve changed many filters over the years and never had one drip before.

Running hot

Just have a question about the 18 can am renegade XMR it gets hot but when you take the cap off it don’t spew it just gets hot and I know it’s computer and will tell you if it gets hot we took the radiator off and cleaned it out and off just curious if it’s normal for them to get hot?
