Use wooden blocks to provide clearance for the Track Repair Group. Place the blocking perpendicular to and below the bottom of the track link assembly. Blocking height should be so that the center line of the pin is at or slightly below the center of the hydraulic cylinder rod. Center line of the Track Repair Group is 181.0 mm [7.13"] above the bottom of the Track Repair Group.

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
