| GP30 36" COOLING FAN & FAN GUARD MOUNTING FLANGE |
My passion is RPM modeling. I try to represent the prototype as best I can and that means I have to
produce some of my own parts. Sometimes this passion can benefit my fellow modelers because I can
make these parts available to you as well. When it is a part that does not require using tools that most
modelers do not have access to and or is a simple add on part or there is enough demand for me to make
the financial investment, I will make them available. This is one such part.
The GP30 and GP35 36" radiator fan are in general basically the same part. There are two differences.
One being the fan grill and the second being the fan guard mounting system. The GP30 grill uses a radial
vane configuration tied together with three concentric wires and has a button top covering the fan hub. The
GP35 uses an open top wire grill with radial wires and concentric wires. The GP35 36" cooling fan is the
same cooling fan used on teh SD38 dynamic brake hatch. The second difference is how the fan guard is
mounted to the fan base. The GP30 uses a flange a the bottom of the fan guard that is bolted to the fan
base. The GP35 has spring clips that are bolted to the same spot on the fan base as the GP30 flange. The
spring clips go up the side of the fan guard and reach over the top to secure it in place.
This part is possible because of the Cannon & Co. part #1706. Everything is there that you need and you
do not have to modify anything. Just add these new parts. The flange will slip over the fan guard and rest on
the already molded base ring mounting tabs. You will see these as four thin semi round tabs coming up
from the base flange.

What you are seeing in this photo is a test shot of the etchings. These were done in 0.006" brass. The
production parts will be done in 0.008" nickel silver which will give them more strength. It is the same
material that the Cannon & Co. grills are etched in.
The kit will provide enough parts for two fans. There are two parts to each fan. As you can see there is the
guard ring bolt flange which slips over the fan guard and will rest on the bolt stand offs. Then there is the fan
grill itself. The fan grill is designed slightly over sized. The concept is the same as the Highliner F unit fans.
You slightly bend the grills downward from the center fan. You are finished when the outside diameter of the
fan grill is the same as the outside diameter of the Cannon & Co. fan guard. You then secure the fan grill to
the top of the guard with your favorite ACC type cement. The concentric wires MAY buckle in one spot due
to the bending and reducing the size of them. Do not worry. After you secure the grill, simply use a set of
needle nose tweezers and crimp it back to shape. That is exactly what happened on the grill above and it
crimped right back to shape very easily.
