1018736 Final Drive Drum Bearing Housing for Hitachi EX200-5

1018736 Final Drive Drum

The 1018736 final drive drum is a structural component used in the excavator travel device and final drive assembly. It provides a rigid mounting structure for the rotating and supporting components inside the travel system.

During excavator operation, the drum is exposed to continuous load, vibration and rotational forces generated by the travel system. Accurate machining and stable bearing and mounting surfaces are important for maintaining correct alignment inside the final drive.

Damage, deformation or excessive wear on the drum can affect component alignment and may lead to abnormal final drive operation.

Compatible Excavator Applications

This final drive drum is used in selected Hitachi excavator travel device configurations, including:

• Hitachi EX200-5

• Hitachi EX210-5

Travel device specifications may vary according to machine configuration, production period and serial number.

Before ordering, we recommend comparing the original drum and confirming the machine and final drive configuration.

Function of the Final Drive Drum

The final drive drum forms part of the main structural body of the excavator travel device. It supports the components required to transmit travel force while maintaining stable positioning within the assembly.

Because the drum works under substantial mechanical load, the condition of its machined surfaces, bearing locations and mounting areas can directly affect travel system reliability.

The final drive drum should be inspected when symptoms or visible damage such as the following are found:

• Cracks or impact damage on the drum body

• Excessive wear around bearing contact areas

• Damaged or deformed mounting surfaces

• Abnormal movement or looseness inside the final drive

• Unusual noise or vibration during excavator travel

If damage is found on the drum, the surrounding travel device components should also be inspected before the final drive is reassembled.

Ordering and Fitment Verification

To help confirm the correct final drive drum, please provide one or more of the following:

• Excavator brand and model

• Machine serial number

• Original part information

• Final drive or travel device information

• Clear photos of the original drum

• Outer diameter, overall height and mounting dimensions when available

Comparing the original component and confirming the travel device configuration before ordering helps reduce the risk of selecting an incorrect replacement part.
