Shop HITACHI EX30 KUBOTA KX101-3 SERIES FINAL DRIVE SPROCKET 21T 10 HOLE | Tonkee®

The final drive sprocket is a key part of an excavator's undercarriage system, which includes tracks, rollers, idlers, and the final drive.

It is the component that engages with the track links and transfers power from the machine's hydraulic motors to propel the excavator forward or backward. In the case of the Hitachi EX30 and Kubota KX101-3 Series, the final drive sprocket is specifically designed to suit the unique requirements of these machines.

Tonkee® 21T 10-Hole Sprocket:
The Tonkee® 21T 10-hole final drive sprocket is a crucial element in the undercarriage assembly of the Hitachi EX30 and Kubota KX101-3 Series excavators. Here, "21T" refers to the number of teeth on the sprocket, and "10-hole" indicates the number of bolt holes used for securing the sprocket to the hub.

Material and Durability:
These final drive sprockets are typically constructed from high-strength materials, often using alloy steel, to withstand the heavy loads and harsh operating conditions encountered in construction and excavation work. The quality of materials used directly affects the sprocket's longevity and performance.

Tooth Design:
The tooth design of the sprocket is engineered to mesh perfectly with the excavator's track links, ensuring efficient power transmission and reducing wear and tear. Proper tooth geometry is crucial for maximizing the sprocket's lifespan and the overall efficiency of the excavator.

Sprocket Size and Compatibility:
The 21T 10-hole final drive sprocket is designed to be a direct replacement for the original sprocket on the Hitachi EX30 and Kubota KX101-3 Series excavators.

Compatibility is essential to ensure the sprocket fits seamlessly into the machine's undercarriage system without any modifications, minimizing downtime during maintenance or replacement.

Installation and Maintenance:
Installing and maintaining the final drive sprocket is a critical aspect of excavator upkeep. Proper installation ensures the sprocket's alignment with other undercarriage components, preventing premature wear and potential damage. Routine maintenance includes inspection for signs of wear and tear, such as worn teeth or damaged bolt holes, and replacing the sprocket as needed to maintain optimal excavator performance.

Performance Impact:
A well-maintained final drive sprocket is vital for the excavator's overall performance. A damaged or worn sprocket can lead to reduced traction, decreased digging power, and increased fuel consumption. By contrast, a high-quality sprocket like the Tonkee® 21T 10-hole sprocket can enhance the excavator's efficiency, productivity, and longevity.
