A: 208-27-00240 is the general supersession part number for this final drive model; 208-27-00241 stands for left side final drive, 208-27-00242 stands for right side final drive. Left and right units cannot be installed reversely.

A: Yes. If the planetary reduction gearbox is intact without gear damage or oil leakage, you can replace only the faulty motor head (706-8J series part numbers) to lower maintenance costs.

A: Rebuilt final drive replaces all worn internal consumable parts (piston, valve plate, planetary gears, friction plates, oil seals), fully bench tested to OEM performance standard with cost advantages. Genuine New is original factory brand-new assembly fully compliant with Komatsu factory specifications.
