Permanent Solution to Lug Wear

Expander System pivot pin technology provides a permanent solution to lug wear. The system can be installed directly into the lugs of a new machine or be used as a spare part for repairs, eliminating the need for expensive welding and line boring.

Eliminate lug wear in no time

The Expander System is perfect for repairs; even if the lugs are badly worn a repair can be made in the field with minimum downtime. If the lugs are worn, the sleeves simply expand to conform to the wear patterns and lock the system in place without the need for time-consuming and ex­pensive welding and line boring - just a re-torque.

Each Expander System comes with a full Lifetime Warranty. We guarantee that your solution will perform as expected from the moment it is installed until the end of its intended lifecycle.
