b. Inspection.

(1) Check the plunger sleeve pin (A) and the

inside diameter of the plunger sleeve pin hole against

the limits specified in the repair standards (par. 3-

60). Replace the pin or the fuel control unit assembly

if they do not meet these requirements. Always

replace the pin if the control unit assembly is

replaced.

(2) Check clearance between lever and control

shaft bushing. Clearance must not be less than 0.023

inch. Check movement of lever. Lever must drop

freely of its own weight. If not, apply lubricating oil

and operate lever until free. If lever does not free up,

replace complete assembly. Refer to figures 3-48, 3-

49 and 3-50 for identification of replacement control

lever units.
