Disassembly
There are no special techniques required for the repair or
replacement of components in the Model 8135 TERMALINE
Load. A screwdriver is the only tool needed. The paragraphs
below outline component removal.
RF Input
Connector
Replacement
The input connector is a patented “Quick-Change” design
which permits easy interchange with the use of only a
screwdriver. This process does not interfere with the essen-
tial coaxial continuity of the load resistor RF input or the
coolant oil seal. For replacement, proceed as follows:
1. Remove the four 8-32 x 5/16 inch round head
machine screws from the corners of the RF con-
nector.
2. Pull the connector straight out of its socket.
Diaphragm
and Coolant
Oil
Remove the diaphragm to replace or examine the coolant
oil. Replacement of the diaphragm and coolant oil are out-
lined in the following steps:
1. Stand the load vertically, with the back end up.
2. Loosen the clamp screw until clamping band is
released.
3. Remove the diaphragm cover and lift diaphragm
from back end of radiator tank. If the diaphragm
is no longer pliable or shows signs of surface
cracks, replace it.
4. The coolant oil level should be about one inch be-
low the top of the radiator cylinder. If the oil ap-
pears to be contaminated, replace it.
RF Load
Resistor
Assembly
To replace the load resistor assembly, proceed as follows:
1. Stand load vertically, connector end up.
2. Loosen clamp screw until clamping band is re-
leased.
3. Lift load resistor assembly straight up out of the
cylinder, allowing the coolant to drip back into
cylinder.
4. Inspect the O-Ring seal which is located just in-
side the mounting flange of the resistor assembly.
