Remove the Acme threaded nuts (7) and Back Plate (1) from the track repair group
Install the new track pin with the cross hole towards the wear surface of the links, and position the pin with the oil hole facing the same side of the track as the other pins.

Align Track Pin, the tooling with the links as close as possible. Press the pin into the link pin bores.

Do not remove the guide pin from the link bore until the guide pin is pushed out completely. Once the pin is installed completely, increase the hydraulic pressure to the proper assembly force. This pressure ensures that the joint is properly assembled to "ZERO" end play.
Pin projection is set by the counter bore in the Piston Rod Cap. Remove all foreign material such as burrs and cold-flowed material from the counter bore and the pin boss of the links.
Move the tooling to the second joint and install the track pin, following the same procedure.
Remove the track repair group.Maintenance and Repair
