Rework Procedure
Repair master joints at the dealer track shop using the Undercarriage Reconditioning Bulletin SEBF8546 (Positive Pin Retention) for proper repair procedures. Use Reusability Guidelines and Installation Procedures for Split Master Links For Reusable Track Parts SEBF8553 and Guideline for Reusable Track Parts SEBF8558 to determine the necessary parts to replace.
