hi,
my lawnboy 8237 mower stopped self propelling itself this weekend, so i disassembled the engine and found the drive gear was shredded into pieces. So i will replace the gear with a new one, no problem. My question is, what lubricates this part? Is the gearbox supposed to be reassembled with gearbox oil? If so, how do you get it in there?
Also while I have the engine all apart, should I replace the piston and rings? When the mower is running it seems quite strong, so what are your recommendations? Should I just wait until the rings are completely worn out before replacing?
THanks, Fish
