Default Water Pump Part II

How do you tell if it is the water pump or the base gasket. I thought it was the o ring for the head. It waws fine. I rebuild the entire top end this summer but did nott touch the water pump that I put on 2 years ago used.I pulled the mag crankcase plug to see if I had coolant in it. There was a lot. I lost power suddenly and it seemed to be only that cylinder.

If the water pump fails it won't pump fluid into your cylinders, that would be from a leaky base gasket.

on the ultras if the seal goes out in a certain way it will let water into the case, but then the water can go to either the mag or center cylinder. sometimes it goes to both and some sleds it goes to one or the other. dont ask me why, its just what i have seen.

the coolant that gets to the cylinders by the leaking water pump is through the gear drive, its open to the case so the water comes in and the suction from each cylinder takes in the water.
water does go through the upper case, under the exhaust flanges you see that aluminum cover piece, that is where the water flows, it hooks to the top of the water pump then gets pumped through that channel into the cylinder, up the cyliners and out the heads.

usually if the water pump seal is bad you will have some leaking out the weap hole at the same times its taking water into the engine.

If you have a leak in the water pump shaft, will it be very obvious in that you lose a noticeable amount of coolant? Could a case with coolant in the bottom effect the volume enough that an extra strong air impulse could be sent to your fuel pump?

When I got it home I checked the resevoir which was very low. It was only misfiring on number 1. Last time it failed I had coolant in 1 and 2.

at first it might be a slight amount, but if a seal really went it could be a lot. on the case reeds the water pump starts to sound like a supercharger at idle, that high pitched whirrrr sounds.

usually not long after that you will get some leaking, had one guy that his started to sound like that and several hundred miles later the sled was drinking water.

it would be hard to get enough water in the bottom to change volume, most of it is immediatly pumped into the combustion chamber and it kills the fire in that hole.

none, on the 96 model they had rubber seals on the crank shaft that created a seperate cavity for the gear drive.

on 97-03 case reeds they got rid of them seals so the mixed gas lubes the water pump.

if you crank has to big seals, like rubber looking or normal seal looking things, its a 96 case and you have to use 2 stroke oil in the water pump.

One more question. How is it that the oil would stay in the pump area and not get sucked into the engine but when the water pump failes, the coolant get suck in?

i have no idea on the year of engine vs body. either got a real early 97 or someone put a different bottom end in the sled?

if them seals are good once that cavity fills with water i would push past them from pressure.

maybe its not the water pump?

well, normally i go with cometic steel gasket rubber coated. but i have 2 cylinders on my sled that are enough to pull my hair out. normally they are bolt on and go gaskets. but for whatever reason i cant get 2 cylinders to stop leaking.

Hey mc, I just blew another base gasket on the same cylinder. I'm beginning to think there is a problem with my reman from us chrome. I am going to try an oem base from poo. I looked for the gaskets from htg but couldn't find them

put some dykem on the case and the cylinder base, use a straight edge and see where it rubs off or stays on.
there is really no way for us chrome to mess up the base of a cylinder. but if you used a die grinder or emery cloth to remove the gasket you could have made some low spots.
heck even a sharp gasket scraper can remove enough material to make a leak.

mine started to leak again the other day, so i used the dykem and filed down the high spot, then used three bond crank case sealant on the gasket.
