    (See fig-2). The bayonet probe has a screwdriver slot to facilitate tightening. NOTE: Required original equipment that has a Red Line may not be replaced by the EGT-701 TIT or CHT installation. This includes but is not limited to all aircraft with adjustable cowl flaps and on aircraft with placards on the instrument panel showing a climb air speed, for cooling, different from the best rate of climb air speed.

  • Page 5: Oil Temperature Probe

    3/8 or 1/8 inch NPT plug (see figure below) located on the front, pilots side of the engine. Insert the optional JPI oil probe supplied in the kit. For 3/8 inch NPT installations, use the supplied brass adapter.
  • Page 6 The oil probe P/N 400505-C is installed by removing the 3/8 or 1/8 pipe plug located on the front of the engine inline with the push rods. This oil galley feeds the valve lifters. Insert the JPI 1/8 NPT probe supplied with the kit. Check for leaks after installation.
