11 Disassembly Procedures
The entire installation process should be conducted in a
clean environment such as a repair shop.
1. After the recloser has been de-energized, remove the
recloser from service.
2. With the recloser in the Open position, untank the
recloser by loosening the six head bolts and washers
on the head casting. Carefully lift the head assembly
out of the tank using the lifting lugs (refer to Figure 3).
3. Invert the head assembly (refer to Figure 4) and if a
service stand is not available, the head assembly will
have to be gently set directly on the six bushing ter-
minals.
Note: The bushing terminals should be set on a rubber mat
or a piece of plywood on a level surface.

INSTALLATION
WARNING:
Hazardous voltage. De-energize the
switchgear before installing this kit. Follow all local-
ly approved safety practices and procedures when
working around high voltage lines and equipment.
Failure to comply may result in contact with high voltage
which will cause death or severe personal injury.
T232.1
!
CAUTION:
Equipment damage. Recloser must
be open (yellow operating handle, under sleet-
hood, down) before untanking. Tripping the mechanism
out of oil will cause excessive mechanical shock to the
operating mechanism, which will cause accelerated
wear and/or damage to the mechanism.
T202.0
!
CAUTION:
Follow all locally approved safety
practices when lifting and mounting the equip-
ment. Use the lifting lugs provided. Lift the unit smooth-
ly and do not allow the unit to shift. Improper lifting can
result in equipment damage.

ruper assembly
4 steel lockwashers from the interrupter support
plate
3 1/2 in. nuts, 3 bronze lockwashers and 3 silver
plated flatwashers from the bushing studs 4. Remove the three hex head capscrews, bronze lock-
washers and brass flatwashers connecting the bush-
ing leads to the bottom of the interrupter assembly
and save the hardware (refer to Figure 5).
5. Remove the three nuts, bronze lockwashers and flat-
washers from the bottom of the bushings on the
source-side (refer to Figure 3) and save the hardware
(refer to Figure 6).
6. Remove the round head capscrews, hex nuts, bronze
lockwashers and brass flatwashers from the contac-
tor plate used to connect the fuse leads, and discard
the hardware (refer to Figure 7).
7. Remove the two hex head capscrews, lockwashers,
and steel flatwashers from the bushing lead support
board (refer to Figure 8).
A. Discard the steel flatwashers and discard the hex
head capscrews but keep the lockwashers for

Capscrew Replacement
There are four button head capscrews included with this
kit to replace the four hex head capscrews currently used
on the interrupter mounting plate.
1. One at a time replace the four hex head capscrews
holding the interrupter support plate with the four but-
ton head capscrews (refer to Figure 10).
A. Reuse the lockwashers with the button head cap-
screws. Discard the hex head capscrews and the
flatwashers.
B. The threads of each screw hole must be free of oil
before applying Loctite to the threads of the button
head capscrews. If oil is present, flush the holes
with alcohol to remove all traces of oil.
C. Torque (using the hex wrench included in this kit)
each button head capscrew to 15 Nm (140 in. lbs.).
Reassembly Procedures
1. In the top of the bridge plate, use the two 1-1/2 inch
capscrews supplied with the kit and the two previous-
ly saved lockwashers to reattach the bridge plate
(refer to Figure 11).
