System for lubrication pivot joint

A system for lubricating a pivot joint of a cylinder clevis, the system comprising:

• a first bushing disposed in a first opening at a first end of the cylinder clevis;
• a second bushing disposed in a second opening at a second end of the cylinder clevis;
• a pin coupled to the first bushing at the first end and the second bushing at the second end, each of the first bushing, the second bushing, and the pin disposed coaxially within the cylinder clevis, the pin having:
• a first side having:
• a first groove provided for mounting a seal;
• and
• a second groove in fluid communication with the first bushing, and provided for transmission of a lubricant;
• a second side having at least one third groove in fluid communication with the second bushing, the at least one third groove provided for transmission of the lubricant;
• and
• a bore extending along a length of the pin from the first side to the second side through the pin, the bore being in fluid communication with the at least one third groove;
• a first cover plate and a second cover plate, connected to the cylinder clevis through a plurality of fasteners, wherein the first cover plate having:
• a first port in fluid communication with the second groove and the first bushing, the first port provided to transfer the lubricant to the first bushing through the second groove;
• and
• a second port in fluid communication with the bore, the at least one third groove, and the second bushing, the second port provided to transfer the lubricant to the second bushing through the bore and the at least one third groove;
• and
• a spring placed between the second cover plate and the second side of the pin, wherein the spring enabling a contact between the seal and the first cover plate.
