I absolutely adore my 6# flywheel, but it does make getting the car over the hump onto the trailer a challenge. The last couple times I had to make course corrections part way up, I could smell that the clutch wasn’t happy. Since Harbor Freight had a sale going for their 2500# winch, I figured, for $50 and a bit of blood and sweat, why not?
This is my highly technical concept diagram on how I wanted to mount it. Given how short the legs are, I opted to keep both legs straight because…I had scrap pieces that were the right length 😉
Here’s my starting point. I snagged a 6″ receiver tube, and since I didn’t have any 2″ tubing long enough, cut up a Harbor Freight 1 ball hitch:
The black-on-black makes it difficult to see, but here is the trailer-side mount, along with the 2″ hitch welded up to the winch mounting plate:
The trailer-side mount welded in place:
It fits with the fuel jug, but it wouldn’t take much wiggle for it to rub, so I’ll likely end up hooking the…hook… to the back side of the receiver tube.
I decided to run the winch off of the truck instead of having another battery on the trailer. It’s sort of a 6 of one, a half dozen of the other situation, but I mostly didn’t want to have another battery to buy, maintain, and maybe get stolen. Because of that, I needed a couple of small mods on the truck side. In the engine bay, the main things needed are a Circuit Breaker (just in case) to protect the truck-side wiring:
About 50′ of 4 ga battery wire, and a pair of very large Quick-Disconnectors for the rear of the truck. This shows both the truck and trailer sides hooked up while I was hunting around for somewhere to put them, and discovered a very convenient M6 bolt hole on a metal bracket that secures the bottom of the rear bumper in place. It couldn’t be more perfect. The shiny bit on the right is one of the valves for the rear helper air-springs:
After running most of the wiring for the truck (save the jumper from the battery to the circuit breaker, to keep the harness ‘cold’ so I could safely work on the wiring) it was time to work on the trailer side.
The winch comes with some pretty uninspired 10gauge wiring, so job one was replacing all of that. I’m also crimping *and* soldering all of the wire terminals. You can see the difference in size between the 4ga wire I’m running, and the stuff it comes with here.
With all of the wiring in place, I could build the jumper between the circuit breaker and battery:
And finally it was time to plug everything in and run a couple system checks. First off, everything was in fact dead with the circuit breaker tripped, which is a good sign. Next, plugging the winch into the truck didn’t let any smoke out. And last, I gave it a pull off of the 12,000 lb D-ring on the back of the trailer to make sure my welding is as extra medium as I thought it was. I still don’t have a ton of trigger time on it, and this is really the first thing I’ve fabbed up that could potentially kill or maim if it comes unmoored. So…I wanted to make DAMN sure the whole thing wouldn’t end up flying across the workshop. And it didn’t, so…win one for the good guys! Or…at least, for me.
