I Broke the Tractor AGAIN! You won't believe the FIX!
What happens here
With the retaining bolts removed, the main pivot pins are still in place. The presenter uses a hammer (dead blow then ball-peen) to carefully tap the pins inwards. He applies PB Blaster penetrating oil and heat from a propane torch to loosen the seized pins and clear out old, hardened grease. He cleans the pin's internal channels using a wire brush on a drill, brake cleaner, and more PB Blaster, continuously tapping and cleaning until the pins can move freely. A specialized grease buster tool is used to force penetrating oil into the clogged channels. Once loosened, the pins are tapped completely out.
Goal: Free, clean, and lubricate the seized pivot pins and bushings.
