c.
Assembly (Refer to Figure 2-21)
(1)
Secure EPG actuator (17) to EPG actuator mounting bracket (21) with four screws (43) and four
new lockwashers (44) (Item 33, Appx E).
(2)
Install one jam nut (42) and one rod end bearing (41) on each threaded stud on EPG actuator
mounting bracket (21). Thread two rod end bearings (41) onto studs until there is 9/16 of an inch
between shank of bearings (41) and forward edge of EPG actuator mounting bracket (21).
Position two rod end bearings (41) to allow insertion of transfer shaft (26) through bearing
holes. Tighten two jam nuts (42) against shanks of two rod end bearings (41).
(3)
Insert transfer shaft (26) into rod end bearing (41) on linkage rod side (39), ensuring lever (36) is
on transfer shaft (26), and insert transfer shaft (26) through opposite side rod end bearing (41).
Do not tighten clamping screw on lever (36) at this time.
(4)
Install two shaft spacers (40) on transfer shaft (26) and tighten setscrews in two shaft spacers
(40).
(5)
Install lever (31) on EPG actuator (17) shaft at angle shown in layout drawing (Figure 2-21,
sheet 4), and tighten clamping screw on lever (31).
(6)
Assemble linkage rod assembly by installing one jam nut (38) and then one rod end bearing (37)
on each end of linkage rod (39). Adjust length so distance between center of two rod end
bearings (37) at each end is 5-1/4 inches. Tighten two jam nuts (38) against shanks of two rod
end bearings (37).
(7)
Secure linkage rod assembly to lever (31) with screw (27), washer (28), new lockwasher (29)
(Item 11, Appx E) and nut (30).
(8)
Secure other end of linkage rod assembly to lever (36) with screw (32), washer (23), new
lockwasher (34) (Item 11, Appx E) and nut (35).
(9)
Slide lever (36) on transfer shaft (26) until linkage rod (39) to EPG actuator (17) is aligned.
Tighten lever (36) clamping screw.
(10) On offset side of lever (25), install stud of cam bearing (23) in threaded hole in lever (25). Apply
sealant (Item 44, Appendix C) to nut (24) and secure cam bearing (23) in lever (25) with nut
(24). Install dust cap on cam bearing (23).
(11) Install lever (25) (with attached cam bearing (23)) on transfer shaft (26) with lever (25) pointing
downwards, and tighten clamping screw on lever (25).
d. Installation (Refer to Figure 2-21)
(1)
Apply sealant (Item 44, Appx C) to mounting studs and three mounting spacers (22).
(2)
Secure EPG actuator mounting bracket (21) to three mounting spacers (22) with three new
lockwashers (20) (Item 35, Appx E) and three screws (19).
(3)
With ECV engine off and engine fuel pump throttle lever in idle position, check that cam
bearing (23) on lever (25) just touches forward edge of fuel pump throttle lever. Loosen clamping
screw on lever (25), and rotate lever (25) as necessary. Hold cam bearing (23) in this position
and tighten clamping screw on lever (25).
(4)
By hand, move lever (31) to full stroke and check that lever (25) and cam bearing (23) stay in
contact with fuel pump throttle lever through full stroke. If lever (25) end of transfer shaft (26)
needs to be closer to fuel pump throttle lever, inboard rod end bearing (41) should be turned
farther on to its threaded stud on the EPG actuator mounting bracket (21).
(5)
Connect the two EPG actuator wires to the EPG actuator (17) terminal block with two screws
(18).
(6)
Perform EPG System Calibration/Adjustment per para e.
