WARNING
1) Fuse Removal/Replacement Procedure
a. Bolt-On Fuse
You will need the following tools for this
procedure:
• ³/₈ Inch Drive Ratchet
• 2 Inch Extension
• 6 Inch Extension
• 12 Inch Extension
• ½ Inch Socket
• ³/₈ Inch Drive Torque Wrench
Note:
The fuse configuration will determine
what length of extension will be
required to access the mounting
hardware. The fuse configuration will
also determine what size of interphase
barriers are installed. The lower
barriers can be removed to provide
better access to the fuse mounting
nuts.
i. Remove the two lower and two upper
mounting nuts, lock and flat washers
from the mounting studs
ii. Remove the fuse from the fuse
mounting studs
iii. Install the replacement fuse on the four
mounting studs. Hold the fuse in place
and install the two upper flat washers,
lock washers and nuts. Torque the nuts
to 12 ft-lbs.
iv. Install the two lower flat washers, lock
washers, and nuts. Torque the nuts to
12 ft-lbs.
v. If the interphase barriers were
previously removed, ensure they are
properly reinstalled.
b. Clip-On Fuse
Note:
The interphase barriers located at
the bottom of the fuse assembly can
be removed to ease the removal and
installation of the fuse.
An optional tool for this procedure is the
Fuse Puller, part # 827D924G01.
i. Place the cup section of the fuse puller
over the top of the fuse
ii. Pull back on the fuse puller with a quick
motion to dislodge the upper portion of
the fuse from the top fuse clip
iii. Set the fuse puller aside
iv. Remove the lower portion of the fuse
from the fuse clip by pulling up and
slightly rotating the fuse in one entire
movement
v. To install the replacement fuse, place
the fuse between the fuse clips
Ensure that the correct barriers are used
with double-barrel fuses. Failure to install
the correct barriers can result in equipment
damage, sever injury, or death.
