Illustration 28 g03319781
Install new track seals into the counter bores of the master track links.
Illustration 29 g03319796
Position the slip fit master joint section.Note: If necessary, use the small press to spread the track links.
Illustration 30 g03319806
Use 100 ton track press to install track pin. Check for proper pin protrusion. Refer to (X) in Illustration 16 and Table 8.Note: Do not apply grease to the track pin or inside the adjoining slip fit master track bushing. During assembly, the grease applied will be captured between the track pin and the pin bore of the standard links. The captured grease will contribute to pin walking in the future.

Install the track seals into the counter bore of the track links.
Illustration 32 g03319824
Align the ends of the link assembly.
Lubricate the master pin with grease.Note: Grease should be used for this installation of the slip fit master pin. The master pin cannot walk inside the track links pin ends due to the design of the pin.
Use a hammer to install the master pin.

All paint, loose rust, metal debris, and dirt must be removed from the mating surfaces of the track components.The paint on the mating surfaces of new track links must be removed before installation of the track shoes. The correct clamping force cannot be achieved if all the paint is not removed. The following methods may be used to remove the paint:
Use a 24-grit sandpaper to remove the paint from the mating surfaces of the track links and the track shoes. A light mist of water should be sprayed on the mating surface during the sanding. The water will help keep the sandpaper clean during sanding.
A paint remover may be used to remove the paint from the mating surfaces of the track links and the track shoes. Make sure that the paint remover does not contact the track seal. The paint remover can damage the track seal.
Do not use a torch to remove the paint from the mating surfaces of the track links and the master track links. The high temperatures can damage the track seals.Note: The track bolt and threads of the track nuts must be in good condition.
Lubricate the threads of the track bolts and lubricate the mating surface of the bolt head with Loctite® C5-A® Copper Based Anti-Seize Compound.
Align the holes in the track shoes with the holes in the track links.Note: The threads of the bolts will be damaged if the holes are not aligned.
Place a track bolt in each hole and start the nut by hand.
