Assembly
Reassembly of the head mechanism assembly
can, in general, be accomplished by reversing the
disassembly procedure.
1. Install counter parts first, carefully secure with rollpin,
see Figure 17.
2. Slide non-reclosing mechanism into position and secure
with pin; slide adjustable lockout lever into position and
secure with rollpin, see Figure 18.
3. Place lockout spring lever, spring guide and spacers,
lockout cam and link assembly, and lockout spring lever
onto their shaft. Note that the hollow shaft end must point
toward the sleet hood. Position this assembly. Be sure to
include flat washers at end of shaft, see Figure 19.

4. Position manual trip lever and insert operating lever.
Secure with rollpin, see Figure 15.
5. Place operating mechanism into position, install pin and
secure with C-ring, see Figure 13.
6. Slide adjustable lockout lever into position through
operating mechanism lever. Install spacers and
capscrews to secure operating mechanism to head
mechanism, see Figure 12.
7. Install self-locking nut onto adjustable lockout lever.
Check lockout mechanism adjustment (adjustment is to
made after entire mechanism, solenoid and interrupter
have been reassembled:
A. Manually close recloser and hold operating up with
one hand.
B. Grasp trip piston assembly and lift until recloser
trips. Observe rollpin that secures trip piston to trip
piston adjuster assembly. Note location of rollpin,
relative to trip adjuster stop, as recloser trips
to lockout:
●
●
If trip piston is in F-PRI position recloser should
trip to lockout when rollpin is about even with
bottom of trip adjuster stop.
●
●
If trip piston is in F-ALT position recloser should
trip to lockout when rollpin is about even with
top of trip adjuster stop.
C. Adjust self-locking nuts (see Figure 20) as required
to achieve correct tripping operation.

Be sure to maintain free play between trip transfer
lever and self-locking nuts. Ideally, loosen one nut
one-half turn, to maintain proper free play, any time
assembly becomes tight.
WARNING
Equipment mis-operation . The two self-locking nuts
must not be adjusted tightly against trip transfer lever .
If nuts are tight, movement of trip transfer lever will
be prevented; as a result, recloser may fail to lockout .
Failure to lock out can cause death, severe personal
injury, and equipment damage .
