ご依頼背景

A customer using a CAT 308E2SR contacted us saying, “I hit the right side cover and the dent is bothering me. I also want to repair the rust caused by deterioration.” This cover is essential on-site to protect hydraulic piping. Leaving it damaged raises concerns about rust progression and potential interference with hydraulic hoses. The customer brought it to us, saying, “Replacing it with a new part is expensive and takes time. I’m looking for someone who can do panel repair and painting to match the original color with a short lead time.” They chose us because we can handle everything from welding to painting in-house.

[Key Repair Points]

① Part Removal and Damage Assessment

• The right side cover was removed from the machine, and the ribs and lock sections on the back were also checked for distortion.

② Putty Shaping and Surface Preparation

• The surface was leveled by applying putty
• Surfacer treatment was applied to prevent color unevenness and rust, and to improve paint color development.

③ Painting (Original Yellow Color Matching)

• Final painting was done with a color close to the original. The finish is comparable to unrepaired sections.

[For Those with Similar Concerns]

If you’re experiencing issues such as “The excavator’s side cover is dented and might rub against the hydraulic hose…” or “The hood and counterweight of the CAT 305E are covered in scratches and starting to rust…”, we recommend early panel repair and painting for exterior panel dents and paint peeling.

If rust from small scratches is left unattended, corrosion can progress internally, potentially resulting in increased time and costs.

Please conduct regular inspections, and feel free to contact us if you notice any areas of concern.
