Regular Inspection:
Visual Inspection: Look for signs of grease leakage, damaged seals, or rust streaks, which can indicate a lack of lubrication.
Play Check: Regularly check for excessive clearance or "play" in the joints.
Have an operator move the stick and bucket through its range of motion while you watch the pin joints.
Use a pry bar to check for movement between the pin and bushing. Any significant visible movement indicates the bushing and likely the pin are worn and need replacement.
Measure Wear: During scheduled maintenance, use calipers to measure the internal diameter (ID) of the bushing and the diameter of the pin. Compare these measurements to the service manual's wear limits.
