Where you live at I can take a look,
I'm 35 miles south of Detroit.
I have been a snowmobile mechanic for over 25 years.
I have all the parts to fix it.
The bushing that support the oil pump/ waterpump shaft goes bad on these engines.
If you grab the impeller it should have zero side to side or up and down movement,
If it does the bushing is bad. The bushing is number 3 in the pic

 

I have replaced everything it is all new all bushings and seals there is no movement in the impeller this is what I didn't get why it was still leaking I wasn't sure if it could be coming from some where else I have taken a mirror and looked under I'm almost possible that's where it's leaking

 

Ok it's for sure the water pump just pressurised the system had a steady drip guess I have to pull it apart and see if I can find an imperfection in the case didn't see one yesterday when I had it apart but could be a very small one

 

I had the same problem with mine and replaced the ceramic seal in the impeller 2 times and it still would leak. The problem was like snow800 said was the impeller AND the oil pump/water pump gear was wore where it fits on the impeller,the edges where the drive fits onto the impeller were rounded off just enough to let coolant weep through and make you want to pull your hair out. There should be no play (side to side) play in the impellar and impeller drive shaft with No bolt in it.

 

With the impeller off, grab the shaft sticking out and lift up slighty toward the plugs, then toward the pull start, then toward the clutch.
If this moves at all, the bushing is worn taking out your seals.
Also the impeller itself MUST be replaced.

 

Ok I will pull the impeller off and Check it I just replaced the impeller and the bushings and the seals I can't get to it till next weekend but I will let y'all know thanks again

 

That rubber thing with a spring on it. Make sure that don't have a hole in it. The seal on the water pumps is the white part on the back of the impeller and the black carbon on the end of that rubber with the spring on it. That seals it up. They put a weep hole on the bottom of the case so if it does leak it runs out of that hole not in the crank case. Check that rubber part with the spring and your shaft play. Thats all it can be if you replaced everything.

 

Ok I'm trying to go home this weekend I'll look at it again thanks a lot

 

thanks yall for the help I didn't get to go home over the weekend i'm going home for sure Thursday night late so ill pull it apart and let you know what I find

 

Don't forget to replace the rubber coated washer under the bolt that holds on the impeller. #8.

 

im going to pull it apart and see if I can find any imperfections in any of the seals I just don't get why it would leak after just replacing it all

 

Ok so I got it apart but I left my manual in lima can any one help me with the water pump section in the manual with pictures or a free download our something

 

So there is play in the shaft after I for it back apart I have no idea why there is 5 miles on the Engine and there was no play in it when I put it together the first time question is so I have to pull the engine to get the bushings out
