TP-1050 rebuild kit for both the Teleflex & Apex TR-1001 & TR-2001. Contains everything needed to rebuild the main governor body. Kit consists of two custom made springs, two sealing washers, filter screen, special 10 micron filter, dynapore disk (TR-1001) O-Ring (TR-2001). Special care needs to be taken when rebuilding the governor to make sure that the dampening washer is clean and the center hole is open and unobstructed. This is located under the 10 micron screen on the lower inlet on the front of the governor. We recommend that you replace your fuel lines when you rebuild the governor.
