Hey I have a coolant leak in rhe motor I can't find. I thought it was base gaskets they were terrible around the water chamber and reeds (front and back). I put new top end gaskets I and I still have coolant in the crankcase.

To replace the water pump shaft seals do I need to remove the motor again and open the crank case or can I remove the water pump cover and impeller and do it from there?

Any other suggestions?

I really don't want to pull the motor again... Ughh.

I already replaced the o rings in the head.... no help but more compression!

I ordered the water pump mechanical coolant seal and a new impeller and an oil seal.

I pulled my water pump cover off and impeller off and found....

The mechanical coolant seal is destroyed! lol its not one piece anymore! So thats my main problem. Under this seal theres an oil seal Im gonna replace as well.....

Ill post about my results when its done.

Well its done...

Took the clutch, flywheel, stator, stator housing, etc off today then the oil seal plate (FKN Philips head screws... RETARDS.) - then finally split the crank case.

All in all replacing the waterpump oil and coolant seals then the oil pump seals was very easy. The hardest part was applying the gasket goop to the case and not having it near the crank or bearings. The rest was easy.

My main problem was that the mechanical coolant seal behind the impeller was SHOT and came apart from the metal backing plate and shaft.

Oh yah and the retard that assembled befor me did not put any rtv or gasket goop between the crank case halves - the water jacket had almost none...... ughhh.

Now its back together but I need the 4 philips head screws that hold the oil pump and bearing cap into the crankcase and a new primary clutch bolt... mine broke.

I was using a torque wrench too, not air tools! lol I knew I shoulda just used the air gun.... Damn bolt broke off in the crank but I got it out EASILY.... with a flat screwdriver....Strange right?

Its done. Just need to bolt on the primary clutch and oil pump! YAY!

If anyone has any questions about this endeavor just ask, Ill help out anyone... I know how to do it now. (unfortunately! lol) :plain:
