Inspecting a used HITACHI EX120 excavator undercarriage part carrier roller is an important step to ensure that it is in good condition and will perform as expected.
Here are some things to look for when inspecting a used carrier roller:
Wear and tear: Check for signs of wear and tear on the roller’s surface. Look for cracks, dents, or other damage that could affect the roller’s performance.
Lubrication: Check if the roller has been properly lubricated. Insufficient lubrication can cause premature wear and damage to the roller.
Seals and bearings: Check the seals and bearings for signs of damage or wear. Damaged seals can allow dirt and debris to enter the bearing, which can cause premature wear and damage.
Mounting bolts: Check the mounting bolts for signs of damage or wear. Loose or damaged mounting bolts can cause the roller to shift or become misaligned, which can cause premature wear and damage.
Alignment: Check the alignment of the roller with the track. Misaligned rollers can cause uneven wear and damage to the roller and track.
Size and compatibility: Check that the roller is the correct size and compatible with the specific model of the HITACHI EX120 excavator.
Price: Consider the price of the used carrier roller and compare it to the cost of a new part. Be sure to factor in the cost of any necessary repairs or maintenance that may be required.
Overall, by inspecting a used HITACHI EX120 excavator undercarriage part carrier roller for signs of wear and damage, checking its lubrication, seals, bearings, mounting bolts, alignment, compatibility, and price, you can ensure that you make an informed decision when purchasing a used part.
What are some common issues that can arise with a carrier roller?
Carrier rollers are an important component of the undercarriage system of an excavator, and they are responsible for supporting the weight of the machine and providing stability on uneven terrain.
Here are some common issues that can arise with a carrier roller:
Wear and tear: Over time, carrier rollers can become worn and damaged due to the constant friction and stress of excavator operation.

Lack of lubrication: Insufficient lubrication can cause carrier rollers to become dry and brittle, which can lead to premature wear and damage. It is important to regularly lubricate the rollers to ensure that they operate smoothly and efficiently.
Seals and bearings: Carrier rollers contain seals and bearings that can become worn or damaged over time. This can cause dirt and debris to enter the bearings, which can lead to premature wear and damage.
Misalignment: Misalignment of the carrier roller can cause uneven wear and damage to the roller and track. This can occur due to loose or damaged mounting bolts, or due to improper installation.
Compatibility: Using carrier rollers that are not compatible with the specific model of the excavator can cause premature wear and damage to the roller and other undercarriage components.
Overloading: Overloading the excavator can cause excessive stress and wear on the carrier rollers, which can lead to premature wear and damage.
Overall, by regularly inspecting and maintaining carrier rollers, lubricating them properly, ensuring proper alignment, and using compatible parts, you can help prevent common issues that can arise with carrier rollers and extend the lifespan of your excavator’s undercarriage system.
