For sale is a KUBOTA 37 HP K1-A Diesel engine, 1961 CC. I took it out of an old diesel power floor sweeper/scrubber. The machine has about 2,000 hours on it. Something broke in the scrubber and parts were not available from the manufacturer. The engine was fine. I bought this scrubber, took the engine out, and scrapped the rest. After priming it with fuel, and operating the glow plugs, the engine started right away.
Right on the engine is a CESSNA hydraulic pump.
A radiator is included with the engine, however, you could need to mount it properly in your machine. Because of difficulty mounting, I test ran the engine without it, always no more than 30 seconds or so to avoid the possibility of overheating.
What is guaranteed: the engine does start and run. It also reponds to the speed control properly and does NOT belch smoke. What is NOT guaranteed: anything else. I have no adverse information about this engine that I am hiding.
