The problem you are facing is that if the system is not cleaned out correctly/adequately at the first time of asking you could end up with a bill of anything up to $250k for repairs (I'm considering cylinders, control valves, swivel, even travel motors here) where a machine the size of a 345 is concerned. The challenge you are facing is how to avoid dropping megabucks on repair work, and that is going to need a clear plan of action put in place regarding how to attack the problem before a wrench is even laid on the machine. This is one of those situations where any mistakes in the repair process can prove to be VERY expensive. My 2c. YMMV.
We'll definitely consider all these factors, since we were trying to sell this machine to some mining company in Mexico.
This machine has about 17,000 hours, it's caught fire twice, and had a giant boulder crush the previous hydraulic pump. So We'll most likely do the necessary repairs and continue trying to sell it or just keep it as a spare for the operators to beat up.

With this in mind, I think your best plan would be to sell her as she sits, and let the new owner put the money required into it.

You will NEVER regain the revenue back out of this machine that you will spend fixing by selling it, or keeping around as a spare.

And unless you fix it RIGHT, you are just screwing the next guy.

These machines have a finite life. If you find contamination everywhere this is the time to sell it as a parts machine. 17000 hours is a good run.
A seller could rinse the crap out of the cylinders a whole lot easier on the bench.
