Compatibility with Sealed Systems:
The 345D bushings are designed to be compatible with Caterpillar's Lubricated and Sealed Linkage (LSL) option.
In this system, the bushings work in conjunction with seals to create a protected chamber around the pin. This design dramatically reduces the ingress of contaminants and retains lubricant, allowing for extended lubrication intervals (e.g., 2,000 hours or more) and significantly increasing component life.
This 436-5391 bushing is used for 6020B excavator.
