Test the Unit after Re-build.
Lay the Unit on the bench. Connect an air supply to the Air Connector fitted to the Inlet Adaptor.
Apply a pressure of 4 Bar to open the SSB Retractor. Release the pressure & ensure the unit
closes fully on the return spring.
Extend the unit again with 4 Bar pressure & close off the air supply so that the unit is held in the
open position.
Measure the length of the extension with a ruler & leave the unit for half an hour. Re-measure
to ensure there has been no movement which would indicate a leak in the air seals.
