hi first post here, what i have is a melroe model 500 skid steer i got for free from a guy at work. the origanal 662 had a crack in the block, but he gave me a 582 motor that i put in there. i just got it runing but were the belt drive come's off the motor and go's up to the drive for the main shaft one side has a decent hydro leak. ive read a few post regarding how the M-600 cover has two adajustments nuts for the clutchs. now for my questions, when i go to remove the two big adjustment nuts do i need to count the turns or mark them. second how much oil will be in there, behind the cover. lastly is there a bearing and seal kit in there, i work for a major cat dealler as a welder and never worked on something like these before. other than the leak it a strong runing machine, need some paint and some TLC but hey it was free, thanks jason.
