I would imagine it means taking it apart and fixing what needs to be fixed. You're not going to go replacing very expensive augers, rings, plates, gears and other things that aren't broken or worn that could potentially go bad. The cost would be too much and a lot of that would be unneeded. New ones are about $9K on a pallet.davidmcbeth3 wrote:OP did not say his unit was obtained as a refurbished machine; although the task of refurbishing should include replacing components that are old that can be replaced (what, refurbish is to just knock off the rust and a paint job?).
When they are built to the standards those are it doesn't matter. I don't know if you have ever seen these boilers up close but here's a hand fired EFM without the jacket. It's a brick shithouse, if you are young you only buy it once.So he has a unit from at least the era before we landed on the moon.
