It may be necessary to disconnect some wiring in
order to have enough room to work. Note wire connections
so that wires can be reconnected again
properly.
11. Slide reservoir panel up and out of the 'T' slots on
the center chassis and move panel to provide access
to main transformers.
12. Complete the following:
a. Disconnect single leg orange wire from E17
on the FET/Heatsink Assembly and slide wire
back through adjacent bushing hole in center
chassis.
b. Disconnect orange wire at E3 on Pilot Output
Board.
13. Note orientation of Inductor, then remove four
lock nuts securing Transformer to center chassis.
14. Install the replacement Output Inductor by reversing
the above procedure, keeping in mind the following:
Reservoir Panel must seat in corresponding
center chassis slots.
The four screws securing the Inductor mounting
plate to the center chassis should have a maximum
of 2 to 5 threads protruding through the left side of
the chassis.
K. Main Transformer (T1 & T2) Assembly
Replacement
NOTES
There are two Main Transformers in this unit. Replacement
instructions are the same for both.
The Main Transformer(s) are located behind the
Reservoir Panel. In order to gain access to the
Output Inductor(s), the Rear Panel of the unit must
be removed and the internal Reservoir Panel disengaged
and moved out of the way.
1. Remove the Left and Right Side Panels per Section
5.04-A.
2. Drain the coolant from the Coolant Reservoir as follows:
a. Remove Reservoir Cap from Reservoir.
b. Disconnect the Coolant Supply Hose input connection
at the Coolant Filter Assembly. The hose
goes from the Coolant Filter Assembly to the bottom
of the Reservoir.
c. Place the end of the hose into a container to catch
the coolant as it flows from the reservoir.
NOTE
Do Not run the pump as the coolant will gravity
feed from the reservoir.
3. Disconnect the Coolant Supply Hose output connection
from the bottom of the Reservoir.
4. Disconnect the In-Line Filter Assembly where it connects
to the Reservoir.
NOTE
Some residual coolant may drain from the In-Line
Filter. It is recommended that a bucket, rag or towels
be placed below the hose prior to removing.
5. Disconnect two air lines where they connect to
the two Solenoid assemblies.
6. Remove the Rear Panel per procedures in Section
5.09-B.
7. Locate the two nuts on the base which secure the Reservoir
Panel to the base.
8. Remove nuts.
NOTE
It may be necessary to disconnect some wiring in
order to have enough room to work. Note wire connections
so that wires can be reconnected again
properly.
