    • PIB 01 - Brake Release Pressure
      Type: TechnicalUpdatesandPublications

      Lower Brake Release Pressure to 250psi from 435psi. This will improve the set time for the brakes and will also lessen the amount of thrust force applied on the drive shaft as well as other forces transmitted through the drive case.

    • PIB 05 - Injector Chain Wear
      Type: TechnicalUpdatesandPublications

      There are two ways in which “chain elongation” or wear can be measured. The first means can be used to measure the chains while they are still in the injector. The second means requires that the chains be removed from the injector and disassembled.

    • PIB 06 - HR440-480 Skates
      Type: TechnicalUpdatesandPublications

      The skate on both the HR440 and the HR480 are reversible. This means that the skates can be used on one side until they are worn to a certain depth, then they can be turned around 180 degrees and reused until both sides are worn.
