Plugging away on Putri-Zilla….
We installed the front roof-top LED light bar. This is the same type bar we mounted on the '86 1544 project, and on the DMC 1450, aka “TUG”. It’s a 42” bar, and it’s curved. You really can’t go wider on this vintage Tucker (52” wide cab) due to the curvature of the roof unless you want to fabricate some special brackets.
With the Thundercat project we added three thermostatically-controlled remote fluid coolers; one for the transmission, one for engine oil and one for hydraulic fluid. You can think of these as small radiators with electric fans. On Thundercat we mounted two under the rear cab floor on the lower truss frame, and the third underneath the bed. But Putri-Zilla doesn’t have any of that real estate available and places to locate a cooler are really limited. To give you an idea of what I’m trying to describe, we even considered mounting a remote cooler on the roof-top carrier or inside a really nice and large Weatherguard box that will be mounted opposite the fuel tank. There really aren’t a lot of options, and we wanted to consider all of them.
But we scratched our heads a fair bit, and there was enough room for one in front of the engine, so Scott welded a bracket to the Tucker frame to support the rear of the cooler. But you also have to plumb the cooler with lines to carry the fluid. With Thundercat we custom made bent steel tubes which makes for a really clean and professional look, but it’s also obscenely time consuming.
As such, Putri-Zilla gets rubber hoses, which to be fair is what about 99.9% of people use. Unfortunately, we needed an immediate 90º turn for at least one of the two lines. There was very limited space to work with and the locally available fittings would not work. I did some Internet research and found some fittings that would work, but Holy Moly are they proud of them! Scott and I discussed more cost-effective options and decided to mount the cooler differently so we could use cheaper fittings. I don’t think it looks as good, but the savings were substantial and we’re under orders to minimize costs. (It must be fun to be a defense contractor, make a bid, then run up the costs and pass ’em on to the .gov.)
Mounted with the inlet and outlet fittings to the front. Return fluid from the orbitrol will come to the cooler and output fluid will return to the hydraulic tank. You can see the in-line thermostatic switch installed at the top of the cooler in the photo. It turns the fan on at 180º.
Here’s a view from the front. Scott carefully re-bent the front mounting flange to match the angle of the Tucker front frame cross member. Note the fasteners. They are what Scott refers to as “Zip Screws”. He has a fetish for these things and his are made for metal buildings and have a rubber washer for sealing.. They are made of hardened steel and are self-drilling, so it’s sort-of like using a new drill bit for every hole. I really don’t like the idea of self-drilling screws being installed where the drill point is exposed after installation, but these are installed into square tube so it’s impossible to contact the point with your hand and cut yourself. The horizontal fittings you see at the bottom of the photo are for the front blade’s hydraulic hoses.
Here’s the underfloor setup on Thundercat.
Note: If you like the bent steel tubes, Scott gets the credit. He is an absolute genius at this, and that’s not an exaggeration. Don’t, however think we got them 100% right the first time. We would get them close, and then a fair amount of “adjusting” which we referred to as the "tweak, torque and spiral” process. The first bend in a tube is easy, but subsequent bends have to start in the right place, they have to have the right amount of bend, and the bend has to be in the correct plane, or radially, around the tube. You are almost always working with a length of tube that is too big to hold it in position to mark, so you use something as a proxy for the tube, such as a piece of welding rod. You bend that, check the fit, make adjustments, and when you’re satisfied, you use that as a model to bend the tube. But that’s when the tweak, torque and spiral comes in to get the tube to fit just right.
I realize this thread is about Putri-Zilla, but I’d like to show you some more of the tube bending detail on Thundercat. (Also the color is more visually appealing than the green.) This is the plumbing to the six-way valve for the front blade. The blue tape identifies lines that still need to be tightened. The unpainted line at the rear was subsequently painted. (That's the supply line to the hydraulic fluid cooler.)
Another view. The wires coming through the center floor area are for the front seat heaters.The rear seats are also heated. (Putri-Zilla will not have heated seats.) If you think the seat heater concept is a little over the top, Mrs. Blackfoot has significant scoliosis and heated seats are much more comfortable for her. (The unfilled holes on the rear flange of the center floor section are where the front seat brackets attach.)
Here’s how the lines come through the floor. Note the rubber grommets that seal and isolate the individual tubes. (The rear line has now been painted.)
It’s really a shame to hide that craftsmanship, but we enclosed the valve assembly in an aluminum housing we made. If you look carefully at the inside of the enclosure you can see we lined it with sound deadening mat as well. At the top front of the enclosure is a trapezoid shaped bracket we added for the transmission shifter. The enclosure ties into that and there is a synergistic support effect. It is really solid.
