The list above is for reference. It is crucial to verify the dimensions (50x400 mm) in your machine.
The 50mm diameter pin 1545280 requires matching bushings. Always replace them together with the pin to fully eliminate play. Also remember the appropriate retainer (bolt through the flange) and shims.
Working with heavy attachments (e.g., a hammer) using a worn 50mm pin is very risky. Pin breakage under load can lead to an uncontrolled drop of the attachment, posing a serious threat to the surroundings.
Pin 1545280 is the main mounting point for large capacity buckets and heavy hydraulic attachments in CAT machines. Its larger diameter (50mm) allows it to transfer much higher loads than standard 45mm pins.
