Cleaning and Inspection

TM 5-4220-226-14&P (7) If necessary to remove neck dam (20) from neck clamp (21), proceed as follows: (a) The neck clamp has guide tracks that guide and hold together the two ends of the clamp. Pull the front of the neck clamp apart. The base of the lever is one end of the neck clamp and the other end overlaps inside for about 5 or 6 inches. (b) While pulling apart, press down on the block end of the neck clamp and up on the lever end. The base of the lever mount stops the lower track at the end and a jog in the pull-apart motion is necessary. (c) After the two ends of the neck clamp are free from each other, slide the rubber neck dam so that the lever end of the neck clamp starts coming out of the neck dam through the hole in the glued sleeve of the neck dam. Keep working the rubber around until the neck clamp is free of the neck dam. c. Cleaning and Inspection (1) Clean all components of neck clamp, yoke, and latch catch mechanism with NID solution and soft bristle brush. Wipe with clean, lint-free cloths.
