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.
Lug wear is a common problem with all machinery. Repairs involve a costly, time-consuming process with significant downtime and must be repeated several times over a machine’s life.
With the Expander System, the repair can be carried out directly in the worn mountings without welding and line boring – a permanent solution to lug wear.
Installation Guide:
The Expander System is installed directly into the existing mounting
Upon tightening the fasteners, the washer presses the slotted expansion sleeve up the tapered ends of the pin
The sleeves expand, conform with the wear pattern and lock the system in the lug ears
Once retorqued, the system will lock from both sides
