4.4 Seal Maintenance
It is recommended that at the suggested time of lubrication the
main rod seal and bushing assembly (FSB) be replaced. The main
rod seal can be removed by threading it out of the face plate using a
standard rod seal gland wrench or spanner wrench. A new main rod
seal can be slid over the main rod, taking care not to touch the seal
material to the threaded rod end. To have this service
performed for
you, contact Exlar Engineering or arrange with Exlar Returns
Department to send your unit in for service.
