We offer two types of Bulldozer track chains:

• Greased Track Chain (Sealed and Greased)
• Oil Lubricated Track Chain (Self-lubricating)

Lucas Parts' Greased Track Chains are a sealed and greased type construction. This kind of chain using a plastic seals between the link and the track pin with a synthetic grease lubrication. The pins are greased before pressing, therefore they are resistant to weather influences and corrosion. The minimal touch between the pin and bush increasing the life-time of premature wear. The seals prevent soil infiltration and keep the grease in the track links. Since the use of grease and seals in the chain, it extends its life more than 20% comparing to Sealed Chain.

Most of Bulldozers use the oil lubricated track chains, also known as SALT chains (Seals and Lubricated Type) due to the increased mobility and speed of tracking. Thus, there is more play between the pin and the bush than with greased track chains. The space between the pin and the bush is vacuumed and filled with oil after the pin is pressed. Premium quality seals are required for preventing excess wear to an oil lubricated track chain. Hence, the use of oil lubricated track chain extends its life more than 50% comparing with Sealed Chain.
