A clevis pin assembly includes a pin that may be removably inserted into a coupling. The pin is structured to have a channel extending therethrough. The channel may receive a lubricant thereby inhibiting the pin from becoming seized within the coupling. A fitting is removably coupled to the pin. The fitting may be fluidly coupled to a lubrication source thereby facilitating the lubricant to be introduced into the channel. A retainer is removably inserted through the pin thereby retain the pin within the coupling.
