This may be a rant but maybe not, a few months ago I found the sump gasket leaking oil on my Craftsman. tractor with 22.5hp Briggs engine so I did this repair myself and all went well I did all the things I felt needed to get this done correctly as I'm a senior with Copd so things don't go easy. So I greased the seal to hold the spring in and also lubed the shaft no gasket sealers etc. Made sure the lip wasn't lying flat on shaft, over all went smooth I do have an automotive repair back round so I am not new to these kinds of repairs. About a week ago I blow off the tractor after grass cutting and notice a small oil film near the rear mount on the oil filter side of engine checked the filter and didn't see anything with the gasket wiped it down and waited till new cutting and film returned. So stuck my hand under motor above the pulley and found some oily grass on my fingers so got a mirror and sure enough there is oil mostly around the seal housing. So here we go again pull the motor it just seems easier than trying this with the tractor jacked up. After getting the motor off and flipped over the oil is around the seal area cleaned the seal and the lip was in place pulled the seal and the spring was also there as well. There seems that the only thing is a bad seal I did notice that the seal seemed to be a lot harder than the new one I purchased. So, I am still a bit baffled as to why the first seal failed but after running it again and checking the new seal is dry but will keep watching. Is it possible that these seals are just not made as well as they should be or was it just Bad Luck that I got a bad one? If it wasn't for the bad sump gasket the old seal would have been still working even being 21 years old. Sometimes you do everything right and things still go south.
