CLEANING AND INSPECTION
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may cause
injury or death. Make sure air stream is directed away from user and other personnel in the area. To pre-
vent injury, user must wear protective goggles or face shield.
Remove all rust, paint, nicks and burrs from mounting surfaces.
Clean all parts with solvent cleaning compound.
Dry all parts with compressed air.
Inspect all parts for damage and replace as necessary.
To obtain correct bolt torque on ground engaging tools, use the following steps:
Clean all surfaces, including recesses; remove all rust, paint, nicks and burrs.
Assemble the component and apply specified torque to fasteners. On components that require more than
one fastener, start in the middle and work out to the ends or start at one end and work to the other end.
Hit the bolt heads with a hammer.
Recheck fastener torque and retighten if necessary.
For a fine cut (finish work), the forward mounting holes of the center cutting edge should be used. For a
deeper cut, the rear mounting holes should be used.
Use floor jack to support center cutting edge (4) while aligning mounting holes.
Install nine bolts (6) and nuts (5).
Use assistance to support left and right side cutting edges (3) while aligning mounting holes.
Install ten bolts (2) and nuts (1).
Position left and right router bits (9).
Install ten bolts (8) and nuts (7).
Use a torque wrench to tighten nine nuts (5) and bolts (6), ten nuts (7) and bolts (2) to 900 lb-ft (1,220 Nm).
