2-22. REPLACE/REPAIR ENGINE COVER; REPLACE INTAKE DUCT ASSEMBLY (Continued)
4 Reshape dented or distorted panels (4, 5, 6, or 7) or intake duct (2). When reshaping the mating surfaces,
components must match with no more than a 1/8 inch (3.18 mm) separation, and overall configuration within 1/4 inch
(6.35 mm) of original shape.
ASSEMBLY:
1 Use retainers (14) to secure the wing head studs (1) in panels (4, 5, 6, and 7) and intake duct (2).
2 Secure acoustical panel (10) in intake duct (2) by securing clip (9) with two mounting screws (11), two nuts (12), and
two lockwashers (13).
INSTALLATION:
WARNING
Death or serious injury could occur if unauthorized or unnecessary
personnel are in the hoisting area. Permit only personnel actually
engaged in the hoisting operation to be near the unit and hoisting
equipment. All instructions for the hoisting operations must come
from one authorized person.
Injury to personnel or damage to equipment could occur from
improper hoisting. Hoist the load slowly to avoid tearing out lifting
bail assembly, slipping slings, or load shift. Do not jerk the load or
swing it from side-to-side when hoisting. This places additional
stress on hoisting components which can cause failure and loss of
load. Be sure hoisting equipment is on solid footing and is
suitable for the size of the load. Watch boom angle and overhead
clearance when hoisting.
1 Secure sling to the four upper corners of frame (3). Secure hoist to the sling above the center of the frame.
2 Lift the engine frame (3) and carefully lower it onto the trailer frame, making sure it does not catch on or damage
engine or pump components.
3 Using hex head bolts, washers, and nuts, secure the frame to the trailer. Remove the lifting sling.
4 Place a small drop of lubricating oil in each receptacle (8) before inserting wing head stud (1).
5 Hold each panel (4, 5, 6, and 7) in place on frame (3) and turn wing head studs (1) until each panel is secured to the
frame.
6 Hold intake duct (2) in place against frame (3) and rear bottom panel (4). Turn wing head studs (1) until panel is
secured to the frame.
