Install ram adapter (1) of Tooling (B) on the ram assembly. Install the 1P-3483 Pin Adapter (2) of Tooling (C) on the frame so that the flat side of Tooling (A) will be toward the link. Use Tooling (D) in order to push track pin (3) out of the track assembly.
Check the track pin for damaged areas. If the track pin is not damaged, remove the track pin all the way out of the track assembly.
Do not remove the track pin all of the way. Damage to the pin bore and link will be the result.
Remove Tooling (D). Make a separation of the track pin with a cutting torch. Hit the short end of the track pin with a hammer until the track pin is inside the bushing.
Remove the next track pin.
