Final answer:
Proper lubrication of a grease fitting is usually indicated by fresh grease oozing out, signaling the cavity is full. However, it's important to follow specific guidelines for certain applications to avoid over-lubrication.
Step-by-step explanation:
When you add grease to a fitting, you can generally tell it is properly lubricated when you see fresh grease begin to ooze out of the relief or edges of the fitting, indicating that the cavity is full and excess grease is being expelled. However, it's important not to over-lubricate as this could lead to grease being wasted and potential harm to seals or other components.
When adding grease to a fitting, you can determine if it is properly lubricated by observing a few key factors. The grease should have a smooth and uniform consistency, ensuring that it can effectively reduce friction. The fitting should be filled with an appropriate amount of grease, neither overfilled nor underfilled, to ensure proper lubrication. After applying grease, check for any signs of leakage around the fitting. If grease is leaking, it may indicate a problem with the fitting or the lubrication process. By paying attention to these factors, you can ensure that the fitting is properly lubricated and functioning as intended.
