While CrazyJerry is digging around for more of the correct pieces (clutch, bellhousing, etc), let's look ahead in time and preview a segment of an actual road test with this transmission swap!
.
The test here is to see if Centurion's Kubota D850 has power enough for a normal 55mph cruise while the overdrive is engaged. RPMs at this speed are at a very nice 2150!
.
Just before the 1:14 mark where the hill crests, you'll hear what sounds like the engine cutting out - it is. When the conditions are right I let off the pedal and the fuel is effectively cut to the injectors, the digital tiny tach loses its injector line pulse, and the microphone records what sounds like a plane running out of fuel.
.
At roughly 1:14 into the video, the uphill grade is finally crested and you can see how easily the speed increases with no additional throttle beyond what it took to skate along at 55mph..
.
To give it a little perspective, the initial uphill grade is very similar in pitch and length to the back forty at the Green Grand Prix.
