I just got an old TD6 series 62 with d282 in it going after sitting for who knows how long. boy it rolls blueish white smoke when starting up and during load changes. dosen't miss at all. runs real smooth.But the governer seems unresposive when i throw it from wide open to idle it comes to a almost a complete stop befrore the governer revs it back up to the speed setpoint. sometimes it doesn't catch it and it dies. I let it run for a few hours and it seems to be getting better. no track on the one side so i cant drive it or see how it handles a load. is there an oil drain plug or something where maybe i could flush and clean and change the oil? or is it lubricated by the regular engine oil?
