[QUOTE="Mike10, post: 81341, member: 5461"] If you had a catastrophic failure of the hydro pumps and motors, you need to flush everything that came in contact with the oil. Disassemble all cylinders and clean. Flush solvent through hoses and lines. Disassemble control valve and clean. Remove axles and clean housings and chain cases. Disassemble hyd pump and reseal. NH recommends replacing the oil cooler because they are impossible to clean completely. Install new filters and use NH filters........ I have reused the oil coolers but spent a lot of time flushing them. You do need to disassemble the cylinders and flush the lines to get the old oil out. A little attention to the details now may save you thousands of dollars down the road. [/QUOTE]
