The 4720524 rubber is an OEM‑reference rubber component for Hitachi hydraulic excavators. This heavy‑duty rubber part mainly serves for shock absorption, vibration isolation and buffer protection during machine running. It reduces strong vibration transferred between assemblies, lowers mechanical noise and relieves impact loads generated in mining and construction working conditions. Aged, cracked or hardened rubber parts will lose buffer performance, which may cause abnormal noise and accelerated wear of adjacent metal components. Customers choose this replacement rubber component for stable physical performance, accurate OEM dimension and reliable supply support from YLCM Parts.

Installation Guide
Clean the mounting surface thoroughly, remove dirt, grease and old residual debris before installation.
Inspect the new rubber for crack, deformation or surface damage before fitting. Do not install defective products.
Align the rubber part with installation position, ensure it fits evenly without distortion or forced squeezing.
Complete fixing according to original assembly requirements, avoid excessive pressure which will damage rubber structure.
After installation, run machine and check abnormal vibration or noise to confirm normal working status.
Maintenance Tips
Inspect rubber component every 500 operating hours, check for cracking, hardening, deformation or surface peeling.
Avoid long‑time direct sunlight, high‑temperature heat source and oil corrosion for rubber spare parts.
Replace immediately once crack or permanent deformation appears, to protect matched metal assemblies from vibration damage.
Check related mounting fasteners meanwhile during inspection, tighten loose bolts timely.
