I think bobcat just sold out to Doosan within the last few years. Have you tried loader parts source? Most of the hydraulic stuff should be common to other loaders if you have serial numbers and such. What parts do you need? Cylinders and hoses can be built and pumps and engines are kind of general usage. The rest of these machines is mostly 3/8 bolts and 1/4 in steel however valves and gears may be a problem.
