The Instandsetzungsvorscriften (I will call this the Instand) is a large technical document that covers in detail the servicing and overhaul of the Motor. It describes the scope of the work that can be done "at the Front" (possibly unit based), the work for Teil-uberholung (at overhaul centres) and, the Grunduberholung (at the DB "Works"). Please note, the overhauling system may have differed in reality but the definition of the work and the level of the unit that could undertake the work is established.
The detail in the Instand is quite high. Interestingly, the scope of the Teiluberholung is quite considerable. Not surprisingly, the Grunduberholung includes all the Teiluberholung work and, gets the engine fully dismantled with the conrods removed, the crankshaft removed, the rear gearcase removed etc, and all dismantled for overhaul.
I do not wish to write all this out here, but, as an indication of the level of the Teiluberholung, it includes the cylinderblocks removed and pistons removed for examination.
So, the Instandsetzungsvorscriften is the complete "overhaul manual" that includes all normal DB servicing of the engine.
Some items, such as the Injection pump, are not covered to full dismantling or reconditioning because they are very specialised.
Overal, there is a lot of information in the Instand.
The next document is also very interesting, the Reparatur Anleitung DB 605 A-B and I will cover that next.
