Abstract
A bulkhead assembly for a track adjust cylinder of an undercarriage system is provided. The bulkhead assembly includes a bulkhead having an opening to receive the track adjust cylinder. A guide element having a hollow cylindrical configuration is attached to the bulkhead and supports the track adjust cylinder. A seal member is axially aligned with respect to the guide element. The seal member has a diameter smaller than a diameter of the guide element. A set of composite bearings is axially aligned with respect to the seal member.
