List of DB 605A engine construction numbers?

That was exactly 100 h plus 25 % extension due to good engine condition.

Hi Matti,

That is very interesting. I can understand if War emergencies caused engine overhaul delays, and different National operators could apply their own standards. However, I think that you wrote that the Genshagen production plant specified the "100/2" overhaul requirement?
The German data from Mercedes-Benz does not specify life-extensions, so that is a question? Beyond that, the Luftwaffe DB605A overhaul manual DLuftT. 3605A-B 0 und 1 is quite specific about the overhaul life and requirements of the DB 605 A, and the 0 (zero) series engines have a specific 100 hour Grunduberholung limit, with a Teiluberholung every 50 hours, and with no restriction on total number of rebuilds. So, I am interested if you have more data about this?

Cheers

Sorry to jump back in,

I can be very specific about the DB 605 A overhaul requirements because they are laid down in three different original German documents.
It is fair to say that "this is the DB 605 AS, not the DB 605 A" but, the documentation for the DB 605 AS says that, it is "the DB 605 A fitted with a DB 603 A supercharger". Actually, this is not precisely correct either.
Nonetheless, the original DB 605 AS documentation specifically lists the DB 605 A information as applicable, including the DB 605 AS parts list that is only an addendum to the DB 605 A parts list, to which it refers.
There is more information about this but, I am interested if you have a confirmation if the Finnish engine life was;
"100 hours to major overhaul and only two cycles allowed (maximum 200 hours running time)" ?
The German servicing cycle was much different to this.

MM44643 engine ( DB601) is on MM9476.

Just about the stamping on MM44643 is another number: NC 0517


Steve, you know where I got this I trust.

Great info Tony. From the C.202 I believe. That number is very close to some of those in the post #112 from Tanzebau. The additional stamping NC 0517 might have a relationship to the local production numbering.

You are correct Schwarze-man.

Hope that number fits into the list properly.
