Installation (Throttle Lever Assembly)
- Install stop lever to throttle shaft. Install a NEW tab washer and secure with throttle shaft nut. See Fig 1 . Holding stop lever on stop, tighten throttle shaft nut securely and bend over tabs to lock nut in position. Install inboard throttle return spring noting that small hooked end of spring is nearest plenum. Locate hooked end of inboard throttle return spring on stop lever. Wind up straight end one full turn and locate in appropriate slot.
- Install countershaft to throttle shaft nut. Secure throttle lever assembly to plenum with 3 mounting bolts. Ensure hooked end of outboard throttle return spring is retained by lever, wind spring up one full turn and locate free end in appropriate slot. Fit overtravel spring. Lightly grease throttle return and overtravel springs with Admax L3 or Energrease LS3.
- Using a depth vernier or depth micrometer, check dimension from mouth of bore to top and bottom of throttle plate. See Fig 2 . Dimension must be within 0.5 mm (0.019 in) total indicator reading across diameter of plate. If dimension is out of limits, adjust small set screw below stop lever.
NOTE:
If NEW throttle levers have been installed, minimum throttle setting of plate must be checked to ensure it 90 degrees to bore.
