Clamp and Lock Assembly
Clamps:
Inspect the clamps for corrosion, bends and cracks. Inspect the clamp holes for cracks and wear.
Locks:
Inspect the locks for cracks at the solder joint. Look for bending or twisting in the tab. Check the hole
for cracking or wear.
Bolts & Nuts:
Inspect the bolts for corrosion, wear, and bending. Look at the nuts for rounding off and thread
corrosion or wear. Try threading the nuts and bolts together to test the threads and the nylon locks on the nuts. If
the nuts will not self-lock they should be replaced. If the nylon washers appear to be flattened out replace them.
Binding Post Assemblies and Communications
Binding Posts:
Check the solder joint for cracking. Test the clamp nut for operation. Check for bending. Older
binding posts were drilled for inserting the communications wire. If the binding post has this hole look for
cracking of the post next to the hole.
Bushings:
Check the bushing for cracks of excessive compression.
Nuts:
Check for rounding off and the general condition of the threads.
Speaker:
Check the speaker for operation using a sound source. Inspect the speaker, wire and terminals for
wear, corrosion, or damage.
Speaker Cup:
Check for wear and damage.
Headpiece Assembly
Band Assembly:
Inspect for corrosion, missing parts, or loose hardware. Check for wear and cracking.
Insert:
Check for wear and excessive hardening of the pads. Check the screw fasteners to make sure they are
still firmly attached to the pad.
Top & Side Pads:
Inspect for wear, compression, or damage. Check that they are still firmly attached to the
band.
Air Train Assembly
Non-Return Valve(s):
Inspect the body parts for corrosion, wear, or damage. Check the threads for condition.
Check for damage to the valve seat. Look for loose plating or corrosion. Check the spring for loss of strength or
corrosion.
Inside Elbow:
Inspect the elbow for corrosion, wear, or damage.
Tube
Inspect for corrosion, wear, or damage. Look for corrosion at the tube ends and on the ferrules where it
can interfere with the seals.
Air Control Valve
Inspect for corrosion, wear, or damage. Look inside the valve openings for signs of foreign
material or contaminates. If the valve operation seemed loose before disassembly check the valve packing.
Check the valve stem for bending.
Air Diffuser
Inspect for contamination or damage. Carefully remove the Lambswool into a plastic bag. Inspect
the Lambswool for contaminates and foreign material. Check the opening in the body for excessive wear. Look
at the body for oil or contaminate saturation.
