s10 mercedes om617 conversion
 

hi all well I have both rigs home and in the barn we are having a blizzard today I might try to get the engine out of the mercedes today next week I plan on getting both stripped of what I need

donor 1 1983 mercedes 300 d turbo 240k on engine will get new injectors and a good cleaning and tuning before installation

donor 2 this will be the driver 1998 chevy s10 ls 2wd auto will be converted to stick 5 speed t5 tranny from a 91 s10

from all of you I have a couple of questions will I have gauges will I have to replace them or is there a adapter or flashing for the gauges will I be able to remove the ecm all together and leave just the bcm or will all that stuff come out and does any one have a complete wiring schematic for the s10

Expect the T5 to die especially a 4cyl version.

I am glad to see the positive input jax how about some reasons bearing failure?? cant handle the hp?? oh I forgot I am only putting out about 125-150 hp explain your reasoning please I would like to know some sound facts as to why this tranny will not hold up it us the same tranny that they use behind 400 hp v8 and they hold up as long as you are not mental and slam gears if it is a 26 spline tranny then it is set up for the more hp and it should also be a wc t5 they are built better than the first ones built lets get some sound reasoning here

Have you made any progress since we last talked? I haven't done any more on mine, and might be getting side tracked because I just scored on a 2.2 Kabota and may see if it might work better.

well getting parts rounded up I am going tomorrow and get the tranny tomorrow I really need to change the input shaft to a 14 tooth I have a clutch for that and they are available without modifying I just wish it would warm up so I can work in the barn and get the 2 torn apart at least get the mercedes engine out so I can get the tranny fitted to it so it is ready to mount in new chassis

how many hp is that little kabota ?? I think 60 would be the least I would consider I had a datsun 720 year ago that had a diesel and I think it was 45 and it was underpowered if you get into trouble adapting tranny give me ring icame up with a fast and easy to make a adapter ring

Witch flywheel are you running I am having to run a 85 back flywheel?

I am using the flywheel from a 240 d 79 model the 240 and 300 use the same flywheel there are a few out there go to car-part.com is where I found mine if you need a bell housing good luck there they are hard to find

I am doing the same but I am putting mine in a 95 s10 because on the obd2 here.
I have tried to run the auto trans but it will not shift so 5 speed here we go.
how are you shutting the motor off?

---AutoMerged DoublePost---

I bought the adapter to turn the Md into a Chevrolet for the trans but as I said it take the
85 back flywheel and the 5 speed is out of a 98 s10 with a 4.3 so bell housing is all in one

Corvette74, I am using the overboost solonoid out of the Benz to shut the motor down. Dennis, I'm not sure how many hp the Kubota is, but some say they are easy to tweak and a turbo isn't out of the question. I pick it up tomorrow, so then I can get some measuring in. I am more interested in MPG's with this one, it is also IDI so veggy oil may be an option.

I can call the salvage yard here they are right next to where they make gehl skid steers I bought 3 engines from him a while back I might even have a turbo for that let me do some looking when it warms up

This motor came out of a Carreir reefer, so they are set up for a constant rpm and load. I think they are set up fairly conservative. I have a couple of turbo options setting in the shop. On one of the other sites, there is a guy that has put several Kubota's in Rangers, so I am trying to pick hie brain. With the kubota, I will have more room for an intercooler, not sure there will be with the Benz, I don't have any room to spare with the jeep.

yea I hear that I have a intercooler I bought a few years ago it has a Toyota logo on it not sure any more about it than that I hope to put it in will probably ave to use elec fan to gain room for that

I picked one up off a Subaru, should be adequate.

just wish it would warm up I am leaving in am to get tranny should have shaft and bearing stuff to change the tranny to a 14 t spline first of the week

Yea, I know what you mean about cold, We actually have snow on the ground today! Doesn't happen here much, got a few days off so maybe I can get something done as well! Keep us posted.

Thanks for you help GREAT INFO
Now where is the overboost solonoid on the 300d so I can use it for a shut off
Vette

On the 300sd it is on the firewall above/behind the valve cover, not sure it is in the same location on the 300d. It may be on the drivers side fender well by the glow controll.

It's more the torque than the horse power. SROD's have been put in to F150's with 300's and 302's. As long as(like you said) your not trying to be fast & furious it'll last. But 3rd gear is always the first to go WC or not. I remember a story about a mustang(fox) where the T5 went out way before the 7.5. I'm not saying don't use it, just keep spare parts.

Got snow on the ground here in WA to. suppose to get into teens tonight. pretty cold for around these parts. Where do you guys get adapter for bellhousing? I was thinking of putting MB in my 83 bronco. I have 300 6cyl gasser now and I figured with some simple mods I should be able to get the same power from the benz. I think they are about 2 liters smaller. the 300 being a 4.9. I ain't worried about speed, just goes back and forth to work and aound in the woods.

I will be making my own I am using a mb bellhousing and a chevy transmission I know there is a place in mn that corvette74 bought his Mercedes diesel info

not for me but might be for some there is also a picture of the overboost any body else have any pictures on this

If your rig is full sized, I think it will be a little weak. I have this motor in my Cherokee, 3900lbs, and it does just fine but wouldn't want to have it in anything heavier/larger, just my opinion. If you are in my neck of the woods, we could meet up and see for yourself.

My mom is in vancouver. I live in LOngview. If you don't mind pm your number to me and the next time I go to Vancouver I will get a hold of you and see if we can meet up. I would really like to see it. MY bronco is full size, I don't think that it is that much heavier then a Cruiser or cherokee. don't know.

picked up tranny today
 

I drove about 6 hrs today and picked up the tranny I was wanting it is a 95 t5 and I was hoping that the chevy bell-housing is longer than the mb and it is by aprox 1" will get more measurements next week here are some pic the clutch is a 85 s10 14t pp is mb and tranny is a 95 have parts coming to convert tranny to 14t should be here next week

corvette 73 also sent me some motor mount pictures I am going to share also they look too good not to share with all of you :jump::jump::jump:

one more tranny pic
 

had one more picture

sorry it is corvette 74 sorry mark

Making progerss, thats great! When I got my parts I think the Benz trans input shaft splines were even (depth wise) with the bell flange, but on the Ranger trans the pilot end is even with the bell flange. So I figure the difference between the Benz trans and Ranger trans input depth is about 1 1/4 in. Don't have a t5 to compare.

it the weather cooperates next week I will have the mb motor out and have my new input shaft an be able to get some real measurements an be able to get adapter plate made will keep you posted you should start a thread about your Ranger I would like to see what you are doing

My 88's door tag reads 6050lbs, a lot heavier that a unibody Cherokee. Maybe not a lot but enough

When I get closer to tearing into it I will. I have a few too many irons in the fire right now. I am torn as to witch motor to use, the Benz or the Kubota I just scored on.

Th Benz motor can be modded. Theres a youtube video of a 300TD wagon drifting at high speed

this one is my current favorite :D

there is another one I saw a while back of a wagon I heard the engine blew anyway I had posted earlier on marks 95 so I got my tranny parts today I am hoping to have engine out and get it test fitted and be able to start assembling soon

How that I have my trans problem under control I need to ask about the waste gate on the om617 in my S10.What is the best way to set it up it works on vacuum it think.
Vette

the waste gate is on pressure not vacuum if you have a boost gauge I don't think I would go over 14 most are using a needle vale to control max boost in the pressure line from manifold to waste gate open the needle valve for less boost if you have eliminated the over boost shutoff then you should just have 1 line going to it when i find a picture I will post it

cleaning
 

well the old Mercedes is all cleaned and stripped down removed injectors and will remove pre chambers tomorrow and adjust the valves also made the wrenches to do it and they work great if any one wants a set let me know I am selling sets also waiting on flywheel bolts took a couple pics on progress

removing the locking nuts is being a challenge and the prechambers well after removal of the locking nuts on 3,4,5 1&2 will not come out soaking with wd40 now the pre chambers are to my surprise a thread size that is really uncommon 22x1.0 I found a thread size you wont believe this but a bicycle puller has the same thread size needed for the prechamber puller I bought it on ebay for 13.99 pretty cheap have the bolts for the flywheel valves are adjusted will overhaul injectors this week have my pop tester built does any one know the range for the injectors to pop off at that is the best for fuel economy

prechamber puller picture worked fantastic

injector tester
 

I finally put my injector tester together and wow talk about slick i figured i would share it with all of you

pump torin T71101 ebay 39.99 11.65 shipping
gauge 3000 psi liquid filled 10.00

brass t and I brazed an old injector line to a 1/4 npt fitting so slick and smooth and under 75.00 with no modifying

all tested at 2000 psi

Very nice!!

Deck, your going to use the baby GM bell housing? I'm thinking about putting a 3.0 in my 94 S10 if I can find one nearby. :pca1:
