Wiseman's 91 W126 OM606
Wiseman's 91 W126 OM606
I have received some help from people on these forums, I definitely want to contribute back at least with a small progress report here.
I will try to go in some sort of order here.
So basically here is the motor as I got it. Motor had maybe 200,000 km on it, hard to say as it was removed without logging the mileage on the cluster.
Bearings seemed to be in nice shape and after I tore the motor down worst that I saw was on 1 or 2 of the pistons there was some light pickup in the cylinder.
Later on I brought the engine to a engine shop, they said it was all good, just needs to be honed.

Here is the car receiving the swap. 1991 560 SEL. At this point I wasnt expecting to have a car so quick. Originally I was looking for a W124, but this car cam along and after seeing how clean it was I had to pick it up.

When it came time to put the engine pack together I took the injectors into a diesel shop, had the injector pop pressure changed to I believe 150 bar.

Below is my first order with Benz Force. Picked up some F-tune rods from Rodney. Yes there is only 5 rods in the picture. I was super shocked when I opened up the order and counted 1 short. I must have recounted atleast 5 times, couldnt understand why this happened. Called up Rodney and he made it right, right away. Benz Force has some pretty good parts listed inventory now. Anyone building a 606 should check him out.

Decided on using a big NAG 1 for the transmission. This specific one is a 722.626. I had the valve body done up by a member on the forums here. Also sent the torque converter out the FTI converters in Florida to get the stall speed bumped up by 1000 RPM.

Motor back from the engine shop. I had shop build the bottom end since I dont have experience when it comes to assembly of bearings and tolerances etc. They balanced the rotating assembly which is nice. One thing that I found really interesting, when it came to fitting the bearing to the connecting rods, the shop said when it came to the stock rods, the tolerances was almost exactly the same for all the rods, 0.001 off here 0.001 there, right where it should be. When it came to the F-tune rods, the said they were getting readings all over the place. All within spec by the book, but not tight like the OEM rods. The shop also was surprised with how much the rods cost. I think it was like $120 a rod x 6 rods. They were also surprised that while the rod looks like a China rod, the rod bolts are carillo, which is supposed to be an expensive fastner.

Right now at this point the only concern I have is making sure no bearing spins on me in the first 1000 km of driving, after that Ill be happy
. Also got the F-Tune valve springs installed. Installed fresh valve stem seals while we were in there.
OMG taking the glow plus out. Previous owner broke 2 glow plugs. I tried taking the other out, every single glow plus broke. Ended up using a removal tool I bought for my GL320 CDI. I have to drill out every glow plug, pull them all out so I could replace them. Since I was already in there I also removed all the pre chambers. I had to make a special tool, like a threaded stud if you may, to pull them all out. I saw some videos of people using dowel pullers and going crazy trying to remove them. With my tool I just used threaded rod, a nut, and a steel block that I drilled a hole through. This method just nicely extracted each pre chamber.

Ok, so its been a very long time and I have not updated this at all.
