Final drive grinding or tractive force falling on your ZX330 or ZX360? A worn 1022195 travel ring gear loses tooth-flank geometry, allowing planet gears to skip load and reducing the tractive force the planetary set can deliver to the sprocket. RITO supplies this heavy-duty ring gear to restore the full reduction ratio and tractive capability of your Hitachi ZX330-series final drive.

In Stock1022195 Travel Ring Gear for Hitachi ZX330, ZX370, ZX360, EX270-5 and EX300-5 excavator final drives. The ring gear is the fixed outer reaction element of the planetary reduction set. Its case-hardened tooth flanks carry the full tractive torque of the ZX330-class machine; correct tooth profile and surface hardness are critical to quiet, efficient torque transmission without premature pitting.

Tooth flank surfaces induction-hardened to HRC 55-60 with a tough unhardened core, providing high rolling contact fatigue resistance under the high cyclic loads of ZX330-class travel duty.
Internal teeth hobbed and shaved to OEM tooth form for correct mesh with the planet gears, minimising transmission error and reducing the noise and vibration that indicate premature wear.
1022195 covers ZX330, ZX370, ZX360, EX270-5 and EX300-5, addressing multiple Hitachi ZX330-class models with one ring gear part number.
Outer diameter machined to h6 tolerance for controlled-interference fit in the final drive housing, preventing ring gear rotation under peak tractive shock load.
FAQ
Q: How do I know when the 1022195 ring gear needs replacing on ZX330?
A: Progressive low-frequency rumble during travel, periodic clunk on hard ground engagement, unequal track drive speed at equal motor pressure, large steel chips in final drive oil, and visible step wear on tooth flanks are the key indicators.
Q: Should I replace the planet gears when fitting a new 1022195 ring gear?
A: If the ring gear failed by tooth fracture, planet gear tooth surfaces are typically also damaged. Replace the full planet set together with the ring gear to avoid rapid re-failure on new ring gear teeth.
Q: What final drive oil grade should I use after fitting 1022195 on ZX330?
A: Use EP 140 gear oil as specified in the Hitachi ZX330 service manual. Drain and replace after the first 50 operating hours to flush any assembly residuals from the new ring gear.
Q: How to confirm 1022195 is the correct ring gear for my ZX330?
A: Match tooth count, module and outer housing bore diameter. Provide the ZX330 serial number and final drive model to our team for cross-reference confirmation.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
