OM 603 conversion from OM617
Hi Everyone,
Im doing a engine conversion from 617 to 603 in my 83 lwb. The 603 is from an w124 and has already been used in my friends 460 300gd from 87 for a short while . He changed it to a Musso engine as he needed more power. I will be using the car for long journeys and I already have a w124 with the 603 engine and I love it for its reliability and simpleness and I know this particular engine is in good condition.
The 603 engine which I have has the oil and pump modified, the air intake is from a 300TD so I will just make a connection to the air filter on the same side. I also have the engine support mounts which fit.
I will be connecting the engine with the original 4 speed gearbox and I know the gerbox - engine connection will fit.
I would like to know what problems will I be going through before start?
I know that I need to buy the exhaust output to fit the exhaust pipe.
How about the glowplugs? I have the original 603 glowplug steerer and can it be easly connected or will I need to make a seperate manual switch for this?
What about the gas pedal cable?
Is there a step by step thread somewhere with such a conversion as I couldnt find it on this forum?
As I start I will document the whole operation on this forum with pictures.
Sorry for my english ;)
big thanks for any help!
it was my pleasure , well done pawel -it works !!
good for you to get it done /not easy especially when you hit obscure problems with parts mismatch etc.
i await my limited edition 'treasure chests' or 'rustler' back catalogue gold editions as a token of appreciation ...
Looks like a neat job.....you sure Axel has not nipped across and done it for you?
All prepped for an OM606 in a few years time now...
looks very tidy in picture - well done !
Im going from 603 turbo to. 606 now. I will have a complete engine less pump. Turbo is available. As far as we know it will need one piston and ring set as it was slapping. The basics are there fir a nice engine. I may post it on the for sale ads when done. Not sure. How much
Axel...just read yr reply.laughed till my stiches hurt

Hope the R&R goes well.
Thanks for all Your helpfull hints...
