Case Study

The Problem

In a standard a Hitachi excavator arrangement, thrust plate wear eventually results in damage and wear to cap screw bolt heads.   This results in great difficulty removing the thrust plates when change outs are required.  To work around this, the thrust plates are often welded into position creating additional work and requiring hot work permits.

The Solution

Geographe created a one piece unit named the Top Hat Bush.  It combines the Thrust Plate and Bush together and is manufactured from a single piece of material for integral strength and durability.  The Top Hat Bush has grease grooves and cross hatching within the bore for superior lubrication.  Geographe clients have reported up to 3 times the component life versus the standard Hitachi OEM arrangement and have no further need to weld thrust plates into position or gouge them out upon removal.
