Nice….

Yeah the engine definitely does great with my regeared SB48 or my RM60 deck.
It still has the stock pump unfortunately. I was looking into a 41XX pump but the 4020 has very little space for the hydraulic pump with the cooler and the filter located in the tower.
A front mounted cooler like the 41XX series tractors have would have been ideal, but the Honda's muffler was in the way.
I carefully lowered the Honda engine in the 646 yesterday. Then connected the hydro line to the pump. Appears to be plenty of room for oil tank in front and battery in the rear. I then took some measurements and cut 1/4” plate for the engine mount. I still have a few things to figure out yet, but optimistic. 👍 Harry

I started to fit all the components into place. Some have to be changed and some creative fabrication to make it all come together. I’m sure others who have been there understand. Take some measurements make a cardboard template check the fit. Make the piece out if metal recheck the fit. I like to weld nuts behind places to make assembly and disassembly easier. So tack weld nut in place, let it cool down then run a tap through nut to chase off the threads. Time consuming activities but well worth the effort. It is coming together nicely, I just have to complete the hydraulic connections and the exhaust. ✌ Harry

I finished the exhaust today. A lot of cutting, fitting and welding were required. I started with some exhaust parts from old GT’s. Cutting them apart and fitting them together piece by piece by tack welding with a MIG welder. After completion I TIG welded the manifold together and added a flanged section to make it easier to assemble. I painted it today with black high heat header paint. Tomorrow I’m going to wrap it with titanium header wrap. ✌. Harry
