4-12. Neck Dam and Yoke Assembly Maintenance - continued.
(3) Inspect yoke for cracks or gouges.
(4) Inspect neck clamp for bends, breaks, or thread damage.
(5) Inspect neck dam for tears, holes, or deformation of rubber.
d. Repair
Repair is accomplished by replacement of damaged parts.
e. Reassembly.
(1) Assemble the neck dam on the neck clamp as follows:
(a) The starting hole for the neck clamp is the front hole next to the sewn (and glued) seam.
(b) Set the neck clamp down with the open ends facing you. Lever end on the right with the locking loop
down. Hold the neck dam in the center of the neck clamp.
(c) Start feeding the end of the clamp (end that does not have the lever) into the neck dam. Work the
rubber around, helping it over the block and keeping the end running in the sleeve. When the rear
sewn seam is just past the hinge tab mount plate on the rear of the neck clamp, stop feeding the
rubber. This is the correct position. Even out the rubber of the neck dam so it is uniform in stretch all
about the neck clamp.
(d) The two ends of the neck clamp are now overlapping. The block that receives the threaded
adjustment arm is protruding through second hole of a new neck dam, and should be in the correct
position.
(e) Next, make sure the sleeve is not stretched unevenly (the hole at the base of the handle should not
be pulled or stretched into elongation).
(f)
Run the nut (1 9) onto the threaded adjustment bolt (1 7) about 1/2 inch. Slip on the lockwasher (18)
and place the threaded adjustment bolt in place through the block. Install locknut (16). Work the
lever back and forth and check that the ends of the clamp are tracking correctly within the neck dam.
(g) Make sure the rear sewn seam of the neck dam is next to, but not on, the hinge tab plate at the rear
of the next clamp. Punch four small holes for the mounting screws and install the rear hinge tab (15)
using four screws (13) and four washers (14).
(2)
Install spring (11) on plunger (10), and insert into latch catch body (12).
(3)
Apply Loctite 222 to the first 114 inch of threads on capscrew (9), and install screw into plunger. Tighten
screw until plunger is in position noted during disassembly.
(4)
Fasten latch catch (8) to yoke (6) with three screws (7).
(5)
Attach hinge (5) to yoke (6) using three screws (3) and three washers (4).
