Lower seal missing 10515?

[mulligan]

I need to replace both upper and lower seals on my 1994 10515 so I started to tear it apart. Got the flywheel off and removed the top seal. Went to work on the bottom got the blade, blade plate, muffler all off and this is where I got confused. There is no bottom seal there was just some crud around the shaft. Am I crazy? Could the seal have totally broken down? The mower would run fine just a hard start when hot and was told that it would most probably be the botton seal.

Yes the seal can break down over time and cause it to start hard. it must be a 2 stroke?
I know I had a snowmobile do that one time I had to hold the throttle wide open to start when it was
hot.

First thing first clean your engine.. Just looking at the picture it looks like a seal in there. My self I buy a bottle of spray engine cleaner, then I spray down the engine with the cleaner and built up dirt I brush or scrap, then spray it down with water. It will be well worth your time in doing so. This also helps to prevents any dirt from entering the engine when you take it apart or remove the seals.

Clean the area X2, Hard to tell, wipe off bore area. I can't tell if there is a seal down in there or if the seal is missing from the bore.

OK I'll clean it and gat a new picture tonight. I really don't think theres a seal in there and if there is I'm not sure how I'll get it out.

if you are going to rebuild the motor just clean the motor and tare it down and replace al the seals so you know it will be right

 

[mulligan]

Not rebuilding just replacing the top and bottom crank seals

 

[Flintmotorsports]

so how are you going to replace the top seal with out taking the crank out of the block?

 

[mulligan]

The top seal part #611396 can be replaced by just removing the flywheel. Perhaps we're talking about 2 different things

 

[Flintmotorsports]

Nope we are talking about the same thing I do this for a living and I have never done it that way but maybe
it is different with the motor you are dealing with.
