This may be better suited for the good MB shop forum, but figured that I would ask here since it is diesel engine specific. I am looking for a good machine shop to perform needed work on a om601 190D motor and om616 240D motor.

I am located in Fort Worth and wanted to see if any of the locals have a shop that they can recommend. There are three machine shops that I have seen or heard of locally. Trinity Casting in Dallas, Mark's Auto Supply in Burleson, and Accurate Engine which has recently moved to Kennedale. If you have used any of them or have somebody else that you would recommend, please do so. Thanks.

I used to live in Ft. Worth. Never really needed a machine shop but I know there used to be alot of shops down in the McCart area around 820.

Contact Will Samples of S&S Imports in Dallas. I don't think he does his own machine work, but he is an expert on classic Mercedes and I'm sure can tell you who he uses.

I have decided to go with Accurate Engine in Kennedale and am very happy thus far. They will be helping me rebuild my 1984 190d 2.2 .Their number is 817-335-4483. Rick is the gentleman that I have been dealing with.

Well after several months of searching for and acquiring parts, the rebuild is in progress. I had a few hard to find parts that really delayed everything. Don is working on getting everything back together and I will report back once it is complete.

Still waiting on re-assembly. There was some question as to whether the main timing chain rail would fit properly but it fit perfectly. Waiting on them to time the injection pump and then everything should be good to go. Will more than likely have to remove some links from the oil pump chain since the new pump has a smaller sprocket. I'll get photos shortly after everything is complete.

How much smaller? You can do the calculations but the oil pump relief valve may only be large enough to deal with the original designed amount of flow volume. Also it will take more energy to turn that oil pump with thick oil when cold.

The oil pump will be turning faster. I would tend to get the right size sprocket . I did not realize the earlier four cylinder blocks had a chain oil pump drive. The more modern 616 four cylinder does not.

I don't have it here in front of me but it is quite a bit smaller. The old sprocket is held on with a nut, the new one is stamped on. The old pump was superceded by the new one. That is the reason that the sprockets are different. It is the correct oil pump though.

Well the engine is back in my possession, however it is not completely assembled. When i took it in I told them that I wanted it fully assembled to a long block and was quoted $475 to do so. When I went to pick it up yesterday the lower oil pan, IP and other items were not attached. I asked why I was charged the full $475 for assembly and was told that they do not do any assembly of the lower pan or valve cover due to customer complaints. When I pressed further I was told by Rick that if there is a leak that customers always bring it back so they have stopped that practice. This really makes me question how they did on the internal engine since I cannot see it.

This is my first time dealing with a machine shop so if this is common practice please let me know. I feel like I wasted my valuable time with bringing items such as the IP and the new oil pump to the shop, only for it not to be installed when I arrived to pick the engine up. I understand that they do not have the proper locking tools to install it, however they knew what engine I had when I dropped it off.

I now have a box of bolts and screws of different lengths that I have no clue go where on the engine. It would have been different if I would have disassembled the engine myself when I took it in. At least then I could have labeled everything and had a clear understanding of how it went back together. I have ordered a paper service manual and will attempt to complete the job myself. I cannot, will not, and do not recommend Accurate Engine.

The assembly fiasco aside, I feel like they drug their feet on my engine. When I dropped it off they were relatively slow. I'm assuming that their work load picked up over the 2 months that the engine was there and they placed my engine on the back burner. Don, the original mechanic that was working on my engine argued with me regarding the new timing rail saying that it wouldn't fit. This went on for two weeks or more. After doing more investigating on my end I reported my findings and was again told that it would not fit. I later found out that he was going by visual reference and never even attempted to fit the new rail. Once Junior took over the job it was ready rather quickly. Pictures of the incomplete project will be posted shortly as well as pricing and a list of things that were done.

Here are the photos. Any recommendations or suggestions on some assistance getting this back together? I called Will Samples at S&S Imports, but he only works on cars up to 1970 or so. Thanks.

My FSM has finally arrived. I am going to get it on the stand and hopefully get it buttoned back up.

The FSM is really helpful for things like this. All you really need is that book and the torque values. Some engine building experience may help, but the book should guide you nicely.

Even though I had the online version of the FSM, I decided to go with an actual original paper copy. The pictures and illustrations are much more clearer in the original paper manual than the online version. I hope to get a good deal of the work done on Saturday since the weather is expected to be pleasant.

I also need to get the special tool for locking the IP and a chain crimper tool for the oil pump chain.
