My Craftsman is kind of the Ship of Theseus at this point. Every blade, mandrel, pulley and spring on the deck has been replaced, as has the drive idler pulley, the chute shroud, the transaxle, fuel pump, intake push rod, crank seal and sump gasket. Amazingly, it still has the original drive belt. The replacement transmission is getting really noisy and hard to shift so when I replace it I’ll probably just go ahead and install a new drive belt. I have a $50 Craigslist replacement transaxle just waiting to go.
