Remanufactured FX assembly provides OEM-equivalent performance at a fraction of new assembly cost for EX750-5 class machines where new travel motor assemblies command high prices.
FAQ
Q: How to diagnose motor versus gearbox failure in the 4395028 assembly?
A: Measure motor case-drain flow at rated travel pressure. Above OEM spec confirms motor section wear. Normal drain flow with gear noise and metal in gearbox oil confirms gearbox failure.
Q: What is the FX remanufacture standard for 4395028?
A: FX indicates housing inspected and recertified; motor rotating group (barrel, pistons, piston shoes, valve plate) replaced with new components; all seals new; park brake release pressure tested before shipping.
Q: What gearbox oil grade should I use after fitting 4395028-FX on EX750-5?
A: Use EP 140 gear oil as specified in the Hitachi EX750-5 service manual. Fill to the correct level and change after first 50-hour break-in period to flush assembly residuals.
Q: How to confirm 4395028-FX fits my EX750-5?
A: Match part number 4395028, 4315069 or 9135220 and confirm machine is EX750-5, EX800-5, EX750 or EX800. Provide machine serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
