Went to an estate auction yesterday and brought home another project.   It, a later model CCC Cub Cadet 782. The 17h.p. series one has limited rotation and has probably busted a rod.  The price was right and it is all there.  It'll go in line with the rest of the projects.   Rick

Is it partially hydro-locked?  Maybe pull the plugs & see if it will rotate fully.

No.  The engine has been removed and is actually just sitting on the frame backwards.  It only  rotates about 15* and goes clunk!

"Clunk" isn't a noise engines should make.  Sounds like rod problems.

That should have been a series 2 in the later 782

I'm assuming the original series 2 was yanked and put into whatever the series 1 came out of.  Rick

To be honest the series 1 was not that much better than the series 2. The reason the series 1 engines failed, wasn't because of a low pressure splash lubricated system, versus a high pressure oil pump system, THE REASON SERIES 1 AND SERIES 2 ENGINES FAILED WAS THE UNDER SIZE DIAMETER OF THE CRANKSHAFT JOURNAL. It doesn't matter how much pressure you have if under low rpm conditions the oil cant move to the out board connecting rod, which is the farthest away and the one that always broke. The reason this was not corrected was the unwillingness of the engineers who designed the engine to admit to a mistake, they convinced Kohler that admitting this mistake who subject them to a higher degree of liability than the engine modification route.

I have a magnum 18 on the bench.  It has a busted rod also.     Last summer I bought a 782 with the replacement magnum 18 engine.  Two days later a rod started knocking!!!      The next week i bought a 682 with a magnum18.  It's been runnning good. So this winter i put it into the 782 to take advantage of the hyraulic lift when pushing snow.   Last saturday i bought the second 782.    So now i actully have two to rebuild.    Rick

Sounds like previous owners don't maintain or take care of equipment, I had two Magnum 18s with 3,000 hours on them, both used commercially, ran like a top, no smoke, no knocks, Landscape owner changed the oil every 50 hours, guess good maintenance is worth a few extra quarts of oil
