bought this 1450 three years ago with a bad kohler engine, bought a apu off a semi that had a non running 14 horse perkins two cylinder diesel in it, it just needed a new lift pump, finally got around to putting it into the 1450, had to get a rad custom made for it but man does it run sweet, need to find a fuel tank and electric cooling fan for it then it will be done, very fun project having to make everything from scratch.

no has to be installed with water pump side of the engine facing the hydro for the proper rotation, was a bit tricky making an adapter for the front pulley on the crankshaft

Looks like a neat project.  Should be fun to run. 

Hmmm wonder how hard those are to find........:rolleyes:

i had a blast doing it, everything is one off not store bought parts got to use some geometry and math i haven't used for a while, having the complete apu helped as i got use the original voltage regulator etc, pust a new set of gauges in the dash, had to find the wiring diagram from rigmaster to figure out alternator wiring but everything else was not to bad, just an old man doing something out of the ordinary.

finally found a fuel tank to fit, had to make new mount brackets, install the electric fuel pump in the steering tower and plumb it all, drilled and tapped a return line fitting into the plastic tank and made a new latch for the hood. now to make new battery cables and find a high cranking amp battery that will fit under the seat and finally get a cooling fan for it then its time to see if it will drive. also have new front tires to put on.

well it is all done and works awesome, got the cooling fan installed today, drove it around the yard and pulled a dead quad to the shop.

What did you use for your rad hoses, just stock hose from auto parts store?

Was changing fan position a PIA?

I'm slowly working on the same idea in one of my builds.  Its stalled right now with work and spring field work. 

Nice job!

all the hoses are 7/8 heater hose and the metal pipes were on the engine, just had to heat and bend them to the shape i needed. the fan is from an old Polaris quad and i made my own mounts, took a bit of measuring and bending of the mounts in a vice to get it mounted how i wanted it. used that style of fan because of the low amp draw as my alternator is only 27 amps, worked very well. used for about an hour and a half pulling 2 diamond type harrows to help dry my yard out and it ran a constant 185 degrees which is thermostat opening temp on that engine.  filled with fuel before and after at it used about a quart of diesel. i am having so much fun with it it almost feels illegal, haha.....dieselman.

Your fuel tank looks like from a 8HP BS on a Hahn Eclipse 30" rider...

This makes me more interested in keeping my 982 and dropping in a little diesel. I researched a Duetz couple years ago, a 2 cyl was too low on HP but they had an awesome co-axial blower to blow cooling air over the heads and barrels of the engine.  They ran slower than the Onan, but the Onan probably ran faster than it should have, I never ran it full throttle.

bought several fuel tanks at auction, this one fit the best, that deutz sounds interesting no rad problems to deal with.

My buddy from WAY back in Grade School, his Dad farmed Big Time. Irrigated all summer. He bought old junked out Oliver 99, Super 99, 990 tractors for the Detroit Diesels in them.  Then he found a Duetz engine, 345 Cid 6 cyl. It was even cheaper to run than the Detroits. One night one of the 3 coaxial cooling fan drive belts broke and ran through the pulleys and broke all the other belts. It tended to run REALLY hot with no cooling air flowing at all, but the next morning it's sitting there pushing out it's 75-80 HP just like it was at normal operating temp, but the temp Guage was pegged. They shut it down, put another cooling fan belt or two on and it started right up and came down to normal temp. IT DID start using a little oil, quart a night.

    All the 2 cyl Duetz engines I found only ran 2500-2600 RPM, my Onan runs 3200. That 2500 is about what I usually ran it when mowing. Underneath the cooling shrouds those air cooled Duetz diesels look exactly like an air-cooled airplane engine, every possible square inch of surface of the head and barrel was/is finned, thin but long and closely spaced fins. Much more cooling surface than air cooled gasoline engines.  There's just so many DUMB Engineering things done inside those Onan engines.

we have many deutz farm tractors in our area they are all high hour machines some over 10,000, only problem has been in the transmissions but the engines are super tough.
