    I bought this 48" Lesco used with this motor and do not know of it's history. The mower was very clean. When buying, I noticed a little oil from the seam of the cover and the crankcase right above the oil drain and figured I'd just watch the oil level. I changed the oil and over filled it a little. (wasn't much). Well today, I was lucky enough to catch it blowing out that same spot and was able to kill the engine. I checked the oil and it was just below full so I was happy not to have a complete failure. I have used it since March of this year.

    I plan on just replacing the gasket but wanted to know, is there anything else I should do while I have this apart?

    Also, does anyone have the torque specs for the bolts? I don't think I will be lucky enough to find a service manual before the repair.

    Any other advise?

    I would suggest replacing the crank seal while the sump is off then just follow the procedure below.

    Good Luck

    Since you have it open I would change the gov. assembly and the oil pump gear your right there would suck to have to tear it all back down again for a failure of an old part.:)
