You will have a much easier time determining the source of the leak if any left over mess from the motor change out and chain replace has been cleaned out. After the unit is cleaned out run it for a bit and check for the source of the leak be diligent and remember the rules of gravity. Oil will travel to the lowest point it never climbs. Sweating fittings may look like they have climbed but its just fine debris soaking up the oil sweat. As far as the brakes some times a little air in the system and cause the unit to be a little more movable . If you have the unit off the ground on blocks you should only be able to rock the wheel back and forth about 1/2 to 3/4". more than this and you have had the chain installed to loose, not to worry you can fix this easy. Remove the tire while machine is in the air or on blocks loosen the bolts holding the axle hub to the machine. pry the hub forward if its in the front to tighten the front chain. pry rearward if its the rear chain. keep tension and tighten a few bolts so it wont more when you relieve pressure on the hub. rock the hub and axle back and forth to check play. check to see if they are "the same". Now about the brakes these units have a separate park brake assembly as in not integrated to the motor. These often fail and can be expensive to repair. The machine should sit when parked and off due to the reliefs in the hydrosatatic system. These will eventually leak down and the machine could roll or move over time. Especially if the reliefs have become weak over time. Check you hydraulic oil to see if its "creamy" or contaminated with water. The oil that has leaked in your machine is it stinky? 80-90 gear oil in the chain cases is smelly. The all season trans diff/ hydraulic oil that's in you hyd tank should be thinner and not as pungent of a smell. if it stinks it maybe left over mess or a bad seal job on the motor replacement. Sorry for the encyclopedia but when I cant see or touch I need to swing with a broad sword. Keep me posted and i hope something here is helpful.</p></blockquote><p></p>
