Thanks for the help guys. How do you get to the water pump? Do I remove the recoil starter and acces it in there??
Thanks

 

Yes and then you have to remove the next small piece of case.Remove the starter recoil housing then you will have to remove the flywheel,then the stator,then you will have to remove the slotted nut on the crankshaft(remember it is left handed threads)then you drain the counter balancer oil (the plug is located at the bottom of the case).You can then remove the bolts that hold the case half on.Once you get that off the water pump is right in front of you.You remove the impellar.The back of the impellar will then slide off and now you can access the seals.Their are two seals in there one is an oil seal which is in the back and the water seal that is in the front.The seal that has two lips on the inside is the oil seal.The one with three lips on the inside is the water seal.Just make a note of how they come out.Get yourself a service manual and you will have all the torques and the basic information to do this.Hope this helps.

 

Well explained Ced. Also Machman use a blunted chisel and hammer to get that stubborn nut loose. Not the "correct OEM way", but it works great.

 

The only other thing I would suggest is to replace the WP bearing while you are already there.

CED - you ever thought of writing manuals? You make it sound so much less confusing than the manuals normally make it out to be. I understood every word you said. I can't remember which particular manual I was reading once upon a time (it was a Haynes), but it had something to do with the fuel tank and the proceedure was something like "using a torch, inspect the inside for signs of rust and corrosion". Well, if I had not have traveled the world, I would not have known that the Limey's refer to a flashlight as a "torch". [img]i/expressions/face-icon-small-smile.gif[/img]

 

Well i just figured since i had just rebuilt a 400 the night before,that i would try and put in a way that even i could understand it.While it was fresh in my head.[img]i/expressions/face-icon-small-happy.gif[/img]

 

I have been reading of our great advice dealing with water pumps and counterbalances. I have water in my counter balance because of a leaky WP seal. But, I am getting water into the compression chamber. Can water get into the compression chamber from the counter balance? I have already replaced head gasket. Thanks for any help!

 

I guess it could get in there thru the seal between the crankcase and the counterbalance area.

 

Well, the counterbalancer is sealed from the crankcase , but the head gasket could be leaking in there. Does your overflow bottle ever fill up while your riding? You wont really see steam out of the exhaust on those like the thumpers if that's the case. If the C/B area was full of water, then it might suck it into the crankcase if the seal isnt in real good shape.

 

Thanks Bubba, the crankcase seal is worn. so it is possible to get water into combustion chamber if the waterpump seal is bad and the crankcase seal is worn. Thanks Man!
