3349573 XCMG GR2605 motor grader planetary carrier

The 3349573 planetary carrier is the core load-bearing component of planetary reduction mechanisms in construction machinery. It mounts planetary gears, planetary shafts, and other components, integrating and outputting the power transmitted by the planetary gears. It withstands significant torque and impact loads, boasts high structural strength and excellent positioning accuracy, and is a key load-bearing component in drive axles and wheel-side reducers.

Technical Parameters

Model: 3349573
Material: High-strength cast steel / Alloy steel forging
Surface Treatment: Blackening or rust prevention treatment
Hardness: Overall strong and tough, impact-resistant and deformation-resistant
Precision: High coaxiality of planetary shaft holes, precise positioning
Applicable Temperature: -40℃～120℃
Lubrication Method: Gear oil splash lubrication

Suitable Scenarios

Suitable for drive axles, wheel-side reducers, and planetary gear transmission mechanisms in construction machinery such as loaders, graders, and road rollers; used in conjunction with planetary gears, planetary shafts, and gear rings to achieve high torque reduction and power output, suitable for heavy-duty, impact, and continuous operation conditions.

Common Faults and Troubleshooting

Planet carrier cracking/deformation: Caused by overload impact or fatigue stress. Replace planet carrier 3349573 and check load conditions.

Shaft bore wear/looseness: Increased clearance due to long-term operation. Replace with a new planet carrier.

Abnormal noise/vibration: Misalignment or poor meshing of planet gears. Re-align assembly and check the gear pair.

Oil leakage/dust ingress: Failure of mating surface seals. Replace gaskets and tighten planet carrier to the correct torque.
