Hoping someone has an idea what this might be, I've taken this engine off twice now, and down to the local mower shop for repair, still leaking once it warms up.
The first time they replaced the output shaft seal, the oil pump gasket, and the O ring on the oil dipstick tube, which is pretty much everything on the bottom of this motor.
Is definitely leaking underneath somewhere that it cant be seen. Motor is clean and bone dry with shrouds removed, nothing running down the sides.
It was ok a few mowings, then oil mostly around the output shaft, all over the electric mower deck clutch, pulleys, flying off in all directions. Pulled the motor off again and
could see the shaft seal was crooked in its seat and the rubber seal edge (in contact with the output shaft) was partially rolled under, partially not.
They replaced the seal again, pretty much the same thing happened again. I finished out the season with it last year, have to add oil every 3rd mowing or so.
Not taking it back to these folks, they're the biggest outfit in town, supposed to be good but since I didn't buy the mower from them, they put me on a back burner and
act like they really don't want to work on it.
Do not know what brand seal they are using, are some better than others? I'm no small engine mechanic, just a tinkerer :)
Can't feel any side play in the shaft, no sign of heat damage to seal.
Really want to fix this, have had this mower a lotta years and have gone all out to keep it in nice shape. details :
Is a John Deere STX38, 1991. Kohler CV12.5s spec# 1249 Runs great, no smoke, oil still pretty much yellow at the end of the season,
virtually no oil usage before this leak, hope someone can help, thanks..... Paul
