Part of the Case Repair Manuals.
Draining the travel reduction gear oil on a CX490D or CX500D starts with two G3/4 plugs, drain and feed. The refill figure is 15 L (4.0 US gal). This Case service manual, part number 47937809, covers that job and the rest of the machine system by system.
It covers the electronically controlled diesel with SCR and EGR exhaust treatment, the variable displacement pumps, the main control valve and the swing and travel circuits. It also covers the undercarriage and track tension units, cab HVAC, and the electrical side down to harnesses, modules and ECU fault codes. Full electrical and hydraulic schematic posters are included.
You buy it once and it stays with this machine. Every capacity, relief setting and diagnostic check is in one book.
