345GC travel torque falling short on grades or travel gearbox making gear noise? A worn 345GC travel gearbox loses planetary reduction accuracy, reducing the tractive force multiplication that large machines need for steep slope and hard-ground travel. RITO's heavy-duty travel gearbox assembly restores full 345GC tractive effort and quiet, efficient final drive reduction.

Three-stage planetary reduction provides the high ratio needed to convert 345GC travel motor speed into the high torque required for slope travel with a 45-tonne upper structure.
Planet carrier pin bores sized and hardened for the high pin loads generated by 345GC tractive force during hard-ground engagement and steep slope climbing.
Floating labyrinth and lip seals isolate the gear oil circuit from external mud, water and gravel contamination common on 45-tonne machine final drives.
Right-side gearbox port orientation and sprocket shaft rotation direction confirmed for direct installation on the 345GC right track drive without mirroring or modification.
FAQ
Q: What are the signs that the 345GC travel gearbox needs replacing?
A: Reduced travel speed or pulling to one side despite equal travel motor pressure, grinding from the final drive housing, metal chips in gearbox oil, and visible oil leakage from the sprocket shaft or motor input seal.
Q: How is the 345GC travel gearbox oil changed after installation?
A: Fill through the level plug to the mid-level mark using EP 140 gear oil. Drive the machine for 10 minutes on flat ground, stop, check level and recheck the oil colour for contamination signs. Change again at 250 hours.
Q: How long does it take to replace the 345GC travel gearbox?
A: A skilled team with the correct lifting frame typically completes the removal and installation of a 386 kg travel gearbox in 6-10 hours including draining, lifting, connection and initial test travel.
Q: How to confirm this travel gearbox fits my 345GC?
A: Verify machine model is 345GC, confirm right-side application, and match motor input flange bolt pattern and sprocket shaft specification. Provide machine serial number for our team to cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
