(5)
Align throttle delay piston (43) flush with
edge of throttle delay cylinder (44).
CAUTION
Do not overtighten two U-bolt
nuts. Damage to injector control
tube or U-bolt clamp could result.
Tighten two nuts (13) on U-bolt (14) snug.
Move injector rack from NO-FUEL to FULL FUEL position. There should be-no binding during
movement of injector control tube (15). Torque nuts (13) to 84-108 lb-in (9-12 N·m).
Starting Aid Screw Adjustment

Backing out starting aid screw will increase clearance between injector rack clevis and
injector body. Turning in starting aid screw will reduce clearance.
For models 5063-5392, 5063-5393, and 5063-539L, use 0.345-inch starting aid screw
gage.
For models 5063-5395, 5063-5398, and 5063-539F, use 0.395-inch starting aid screw
gage.
(4) Insert starting aid screw gage (46) on 3R injector rack (41) between clevis and injector body
(11). Prevent gap adjusting screw (29) from turning and adjust starting aid screw (28) to
required setting. Move gage back and forth along injector rack until a clearance of 0.016 inch is
noted. Remove gage.
