Swaping a 617 for a 606

I've begun my engine swap, the donor engine a om606 arrived and has been started up to verify the engine and mechanical pump from a om603.

http://www.youtube.com/watch?v=99TlCzG5pEs

This week a manual tranny (711), flywheel and clutch from a MB Sprinter will be bolted up to the engine, this tranny is on loan from a local mechanic so we can be sure of which tranny to buy.

Here are a few pics of my om617 before it's taken out and one of the om606.

Any tips from those who have gone this path before would be deeply appreciated. Any tips/help for engine mounts, oil pan clearance and any mods to bolt the prop shaft to the tranny would be great.

RE: Swaping a 617 for a 606

please check out my thread...


http://www.pointedthree.com/disc/forums/showthread.php?tid=14980&po...



i have succesfully had a 606 fitted. the sump had to be re shaped a bit to clear the diff. this was the biggest concern as an original G300TD 606 sump is close to 1000 euros!!

OFCOURSE, THE WASTEGATE WAS CHANGED, THANKS TO ALL THE ADVICE I RECIEVED HERE...

gearbox options vary but the wolf, van box will be good if you want bigger tires. i went for a 5 speed from a w124 .

RE: Swaping a 617 for a 606

Thanks hus55, what modification did you do to the sump? I checked out your thread but couldn't find any pics of your modified sump. Do you have any?

RE: Swaping a 617 for a 606

nice one karl

how did you know i am proffesional dry cleaner. and hoffmann presser since the age of 9....

way@out, i will find pics of the sump mod.


generally speaking, i had the rear corner that just touched the diff cut back and re welded using the metal from a spare sump i had.

did i mention that i fitted a body lift too. my mechanic said it helped clear the sump from the diff too

RE: Swaping a 617 for a 606

I'm currently trying to choose my new gearbox. My mechanic has suggested the 711.620 gearbox, but I can't find any information about the gear ratios. Are there any known sites with data? This gearbox has been installed in sprinter vans with engines that have similar torque to that of the om606. I've googled it but haven't been able to come up with anything.

RE: Swaping a 617 for a 606

Thanks Jonathon, but the manual gearboxes listed are not capable of handling the 606's torque, according to my mechanic.

RE: Swaping a 617 for a 606

As far as I know there isn't a manual transmission that will work behind the 606.  It seems odd, there must be some newer, more powerful, diesels that come with manual transmissions.  I'm just not familiar with modern MB diesels as MBUSA is too stupid to bring them over here to the US.

RE: Swaping a 617 for a 606

Sprinter gearboxes will work, I've currently got a 711.605 bolted on the engine. It was bolted up to check if the starter, flywheel and clutch would work, they do. My mechanic suggests the 711.620 because it should handle the engines torque alot longer. Other possibilities would be a SLK 230k gearbox or E270 cdi. But before choosing I'd like to run the gear ratios on a calculator to check the crawl speeds and road speeds to see which one would best suite my G usage.

OT: here's an interesting site with alot of MBcodes I found during my hunt for gearbox ratios. I used google to translate the japanese and it worked well.

RE: Swaping a 617 for a 606

By "work" I meant that the transmission won't get hammered to death by the engine. 

For on road travel, shoot for 2600rpm at your favored road speed.  The engine really likes the 2400-2800rpm range and starts sucking fuel past 3000rpm.

RE: Swaping a 617 for a 606

way@out , i am currently using a w124 5 speed box with the 606. i am very very happy with it. the 1st gear extremely low,even when using the 33 stt's. i will get the exact number off it this weekend

on another note, i am still striving to get the max power from the 606. i have had alot of great help from various guys here and recently stumbled onto another idea....

i had the 603 pump adjusted by the guy that fitted the intercooler and wastegate. i think i was taken for a ride to be honest... i dont think he did anything to the pump at all i was recently given the number of a guy in limassol that only specializes in fuel pumps etc. i will taking him the 606 pump and the 603 pump hopefully next week. what he plans to do is remove the plungers from the 606 and fit them to the 603. i read something on these lines on link that was posted under my topic about my engine conversion recently. apparantley these guys out in europe change the plungers for more power.

the 603 pump does get the 606 up and running but i dont believe it delivers the full potential of what it should. logically speaking it seems wise to change the plungers on the 603 pump with those from the 606 as the 606 engine was using them in the first place. i cannot see any danger or probloems in this.

will keep you posted.

RE: Swaping a 617 for a 606

Hus55,

If I'm not mistaken you've got 7mm plungers in the 606 pump and probably 6mm (I've read that not all are 6mm some are 5.5mm) in the 603. There is a well know Scandinavian shop called Myna Diesel, I've herd that they're probably the best at swapping the plungers and tuning the pump. But as always (probably most of the time) the best is a bit expensive. The mechanic who's doing the work on my G swapped a om605 into a 190d, he went to his local diesel pump shop and wasn't satisfied with their work, or was expecting a larger increase of power. If you do get great results be weary of the gearbox, as AlanMcR says the 606 will hard on the gearbox (hopefully it would kill the clutch first). I've read that the best boxes are the Getrag 717.450 which where originally installed in the 300E and 320E 24V. But from what I've seen only in sedans. There isn't much info on swapping a 606 into a w460.

How have you lifted your G to clear the oil pan from the dif? spacers or springs? How high?

711.605- 4,9, 2,53, 1,49, 1,0, 0,78, R4,59
711.620- 5,05, 2,6, 1,52, 1,0, 0,78, R4,76


Thankyou so very much Luky,

RE: Swaping a 617 for a 606

From what I hear, Myna in Finland does a lot more than just change plungers.
They recalibrate everything in the pump to handle the extra fuel and keep the results drivable.

RE: Swaping a 617 for a 606

hi there, i have a 2" orc bodylift and a 2 " orc coil lift.

however on my first day off road the pan caught the diff by a few mm's so i had itre shaped to clear the diff. it was done very well but a week after it was refitted a very small leak occured, very minor but i never got round to sorting it out till this week.

about the myna diesels, they are a very good company achieving great results. if my 603 plungers are 5.5mm and the 606 plungers are 7mm i dont care if i end up changing the gearbox every 6 months i want power!!!! full stop. thats why i went to all this trouble

i will dig out pics of the sump
