I sell a lot of the V1702 engines, Even though Im a Bobcat dealer I dont purchase them through Bobcat, Currently I sell them for 3500.00 exchange. Warranty is the same as a new engine 6 months, and no one has new anymore. Oh plus frt.

I get my full re-build kits for AUD $900, thats pistons/rings bearings gaskets. On top of that were dry liners for the bore at $20 each (genuine kubota are very pricy for these).
But you need to consider the injection system, there is no point in re-conditioning the engine if your pump and injectors are shagged. About $400 for new nozzles and a pump re-co.
All up parts will run you around 1,400 - 1,500. Then you need the machining work to be done. You really should get the head done too, its a small price to pay if you get the bttom end done, then you know its rite!!!
Make sure you get the radiator checked out and replace the thermostat. A few extra bucks on a re-co engine is well worth it.
New engines over here run about the 5K mark.
You can replace the V1702 with a V1903, you will need to swap sumps though. There are Dadong engines floating around the paper, they are a V1702 copy that are still being manufactured.
