I am including the pictures of the installation of my front heat duct bilge blower.

I used a Makita 4” cutoff grinder (die grinder), fitted with cutting discs, to make the cuts that you see, that are under the front cab floor, just next to the gas pedal, and emergency brake lever pivot. I did have to remove the grinder’s handle and safety shroud to do so, and then being extremely careful, and with a very tight grip, because that thing has gotten loose from me before, and those discs can slice through flesh, like a knife through butter.



I realized after I had made these cuts, that I should have taken a “before” picture.

Oh well.



Note how the ducting folded hems, have been ground flush with the duct circumference at each end, so as not to interfere with the coupling seals.



I was able to use cut out parts of an old motorcycle tube for the ducting connectors (couplings), that the local Hogley Motorcycle Shop folks were gracious enough to give to me for the asking. The size of the particular tube I was given, is 3.00/3.50-21, although I trust that any size of a similar tube would work, as long as it has a 3” diameter cross section.



Since these rubber couplings seal, and hold so well, especially when further secured with plastic wire ties (ty-wraps), I saw no need to mount the bilge blower feet. I did however, place a piece of ˝” thick foam rubber carpet padding in between the bilge blower base, and the bottom of the cab flooring, so as to dampen any vibration, and any jars resulting from the vehicle impacting road dips and bumps.



Since I have a whole bunch of the before mentioned carpet padding, I figured it wouldn’t hurt to help line the cover pan with some as insulation. I also covered the hole in the said pan with duct tape, as I see no need for another draft hole.



Be sure to consider using a DC Motor Speed Controller for such a blower, as can be found described in this article:
