Old OM 617 installed in a 60's Land rover
 

My Son has bought a 1964 Series 2A Land Rover fitted with a OM617 non turbo, could any one help me find the engines year from the engine plate?
I can't upload a photo but from the plate

Original Mercedes - Benz
Tauschaggregat
Teil-NR 617010070080
Aggregat Nr 423195

I can't but someone here can. They'll chime in soon I imagine.

Thanks with my School Boy German I think its an exchange unit? I was going to find a year asif its old enough it keeps the vehicles Historic taxation class.

If it is a us import the turbo engine became available around 1982. 81 in a coupe iirc.

Its in the UK

1978 in the W116 chassis.

The 617 showed up somewhere around 1976 and was last used in a production car in 1985. They may have stuck around longer for industrial or non-MB applications, but MB's went to the OM60x series engines in '86.

Any way of knowing the year of the engine?

It is a replacement motor based on the Tauschaggregat ID plate.

The conclusion of this exchange was to contact Mercedes in Germany.

My local Mercedes agents where most unhelpful No VIN no info which was disappointing.
Would any one have a contact in MB Germany?

The date is marked on the block behind the injection pump IIRC. One of my engines has "26 C 80" ie 26th March 1980.

They were still sold in the G wagens however into the early 90s, so there's a chance (however small) its a post '85 engine.

Found these marks cast on the Cylinder head

Not recommending buying stuff from him. But you could go to the diesel giant site and find the part were it tells you how to look up the engine number.

If the Engine was built and put into a Car close to the middle of the Block on the fuel injection pump side right under where the Head and Block meet is a stamped number (hard to see).

If say your Car Engine threw a connecting rod and it was still under warranty and Mercedes replaced the Engine it will have information on a metal plate that the original Engine Blocks in cars did not have. That is as much as I can remember on it. Can't remember the location of the plate.
