support spacer with wire ties. Connect upper coil lead
at bushing.
18. Reattach hardware to secure long conductor at bushing.
19. Tank recloser.
20. Test recloser. Manually operate recloser to verify proper
operation. Perform an Insulation Level Withstand and a
Minimum Trip Current test to verify proper operation.
Solenoid frame and hydraulic mechanism
Disassembly
Normally, the components of the hydraulic timing and
counting mechanism will require little or no maintenance. To
disassemble the mechanism for cleaning, inspection, and
possible parts replacement, proceed as follows:
Hex nut and
lockwasher

Pump piston
Plunger
Figure 9 . Solenoid frame removal
1. Remove interrupter and solenoid coil assemblies, refer
to preceding instructions.
2. Remove three hex nuts and lockwashers which attach
solenoid frame to support stringer and mechanism
frame, see Figure 8. Remove C-ring that secures
contact rod to operating linkage. Carefully remove
solenoid frame assembly.
CAUTION
Equipment damage . Carefully support the plunger
and pump piston when removing or installing the
solenoid frame assembly . If either the plunger or the
pump piston are nicked or damaged, the recloser can
misoperate or fail to operate .

3. Remove slide valve and spring by removing three
screws and lockwashers, attaching trip-piston stop and
slide-valve stop and gasket to solenoid frame.
4. Remove timing plate and gasket from solenoid frame.
5. To remove trip piston assembly, see Figure 10:
A. Using a wire hook, raise check-valve ball seat out
of underside of casting to expose tension spring,
which is part of trip-piston assembly.
CAUTION
Equipment damage . Do not over stretch the trip piston
return spring when removing the piston assembly .
Over stretching the spring can affect the sequence of
operation and reset times .
