7N8021 Plate-Spacer — Cat 120G 130G

This Plate-Spacer is a crucial component within the hydraulic system, designed to maintain precise spacing and alignment between other parts. Manufactured to meet rigorous Caterpillar standards, it offers superior durability and resistance to wear compared to a damaged or worn spacer. Operators may notice hydraulic system instability, leaks, or unusual noises if this component begins to fail.

Failure Symptoms

A failing Plate-Spacer might initially cause subtle hydraulic system instability or a slight increase in noise. If ignored, this can progress to noticeable leaks at mating surfaces or a gradual loss of hydraulic efficiency. The risk of accelerated wear on adjacent components increases significantly if the spacer's integrity is compromised.

Installation Tip

Ensure that all mating surfaces are perfectly clean and free of burrs or debris before installing the new spacer. Do not reuse old seals; always install new ones to ensure a proper seal.

Service Note

Inspect the condition of seals and O-rings that interface with this spacer plate, and check for any signs of wear on adjacent components.
