I recently traded out some work for a bobcat meldre? 743 ds it has a 4 cyl diesel engine that runs front to back (I think its a kubota) (I dont know a lot about skid steers but have been a linde forklift tech for some time) the back story unit had been sitting without starting for 3-4 years had some minor leaks and leaked out most of the hyd fluid. after a little coaxing we fired it up and runs good a little blow by but nothing major. got in to move the thing around and very noisy (cavitation sounds whining) immediately shut it down and checked hyd fluid, it was not showing on the stick added 3-4 gal and tried again. got the bucket moving and the boom up. tried to drive and vary little movement abosolutely no movement when the yanksticks are crossed up just scream. I got it on the trailer with a little pull from another truck and brought it home once home pulled off the trailer the old cat seemed a little stronger but still wont pull its weight up a grade wont push into a pile of sand. I assumed there was a lot of air in the system so i hooked up a hose to the bleeder hole on the drive pump and ran to tank ran it for about 30 mins let rest overnight and repeat i notice a little improvement but still wont move when the sticks are crossed up and very weak pushing into a pile or going up hill. I noticed hyd oil is foamy. where do i go from here. anyone have hydraulic schematic
