Looking for a D650 or D850 engine

[RoscoeP]

Hello all! Im finally getting around to finishing a project that i inherited. Ugh. I bought a B6100e tractor that needed a clutch...come to find out it had a blown head gasket. Got it going and it has a ton of blow by. Sooooo im looking for a replacement.

You can do a D650, D750, D850, and D950 they are all physically the same size.

Now there are 2 versions of the D850 one with a water pump and one without, and all D950's have a water pump.
You can fit the water pump version in there but you will have to alter the piping to the radiator and wiring to fit it.

How much are you looking to pay?

I have a fully rebuilt, all Kubota parts, D850 non water pump version available.
But it's been out of most peoples price point.

Rebuilding a D650 is in the range of ~$2k and that's if all the major parts (block, head, crank, cam's are good).

Im just looking at options. My mechanic will do it for $1k plus parts. That includes removal and installation of motor. But there may be other motors out there that are used but ok too.

You'll be hard pressed to find any engine, that will fit, that's in good running condition for cheap.
All of the 50mm series engines are getting really hard to find.
