I am attempting to bring a 1993 L555 back to life. Both hydrostatic pumps and both motors have been rebuilt. I am now in the process of putting everything back together. Once I get it all assembled I will fill with new fluid but what about the filters? Should I put new filters on now also or wait until the pumps and motors are broken in? Are Wix filters good enough? Are they better or worse than filters from the NH parts store? Should I do anything to the chain case besides refill with fluid? I already cleaned the magnets and suction screen but I haven't attempted to clean the chain cases. Anything special need to be done to prime the hydraulic system and/or the diesel fuel system? I also replaced the rear axle seals and outer bearings since they were leaking (baling twine). Thanks, Brett
