Engine Adapter is there any interest ???
Been talkin to a machinist !!! He can make an engine adapter from the Mercedez 3.0L turbo diesel ( OM617 ) to the stock Jeep manual trans ( AX - 15 ) which should be the same bolt pattern as the automatic ( aw-4 ) ( don't know if this trans would survive the diesel's torque ??) !! :c: :yeah:
Any ways ..... He can make a run of 5 adapters and I was wondering if anyone would be interested in the others ???? :yeah: :ok1: This is a fairly inexpensive way of making the YJ ( and possible TJ ) into a Diesel !!! :U::U: |
I honestly don't think the ax-15 will stand the torque of a diesel,I wrecked 2 of them in one summer with a wore out 4.2l carb and I only run 33's on it:humm:good luck with it:U:

jmho As of March 26th .... Vlado had 900 miles of trouble free service out of this setup as a daily driver !!! Check his thread.... It is a very interesting read !!!! :U: |
I doubt I put that many miles on the 2 ax 15's ,all the power to him and I wish him luck

same here trashed two of them in my jeep with a stock 4.2 and 31" and 33" tires. i'm not saying a wasn't hard on them. but if you want to push hard i'd look for a HD tranny

This is a sweet install but the OM 617.952 Mercedes 3.0L only puts out 120 horse and 185 lb/ft !! And that is quite a bit shy of stock 4.0L gas Jeep engine !! BUT , high 20 to low 30 mpg's are attainable !! Stock Jeep AX-15 will hold up without a problem !! This is what I have in mind !! Check out Vlado's thread in this section !! Then PM me ; I can mate OM 617 Mercedes 3.0L diesel engine to a wide variety of manual transmissions . The ease of finding these motors and relative cheap price of swap to get great mpg's is well worth it !! |
With the present economy , I now have 3 to 4 days off per week and twiddling my thumbs got old 2 months ago !!
I am gonna offer the Bell housing the adapter plate and the cover plate ( to cover all gaps between engine and bell ) !! I have alot of transmissions from alot of vehicles bolt pattern ( but I do not have every vehicle nor every year ) Since I am doing a 94 YJ and bolting OM617.9 to Aisin AX-15/NP235 combo, If someone has this combo and wants my KIT , I can offer the pilot bearing and Flywheel ( either NEW or Used ) in the KIT ! Thinking of price point around $ 650 for ( Bellhousing , Adapter plate , and cover plate ) for the vehicles I have patterns for !! And $ 725 (used flywheel) and $775 (new flywheel) for YJ/TJ where I can offer Flywheel and Pilot bushing in addition to other pieces ! I am planning to offer the KIT as a NO SWEAT AND NO SWEARING kit !! I will test fit every KIT before it leaves !! With some KITS I can offer a provision to upgrade your clutch from Mechanical to Hydraulic (like what is available on the YJ ) ; If you request it when ordering . If everything goes to plan I should be able to start shipping KITS from first run in approx 8 weeks !! PM me if interested !! Or if you have any questions !! |
I wouldnt mind the adaptor to bolt that motor up to a 318 and 3.9 bolt pattern. I want to put in a built up automatic so all i would need is the bellhouse and the flywheel set up. any idea for price?

New to this board. My current project is a 1990 Cherokee with AX-15 and Cummins B3.3. I was inspired by a Wrangler project on Diesel Truck Resources.
http://www.dieseltruckresource.com/d...j-t112807.html He has over 15K on his project. It depends on how you drive the rig - Street or heavy offroad. Just bought a low mileage OM617 and was inspired by several projects posted. Keep the projects coming. Chris AKA: BigBlue |

post those plates up on pirate too

would like to get a chevy manuel or auto trans adapted to a om 617 for a reasonable price my understandig is that a manual trans wont work becauseof balanceing issues is that the case thanx

IIRC the stock OM617 starter bolts onto the adapter plate and the 700R4 isn't designed for the starter to bolt to the bellhousing, so you'd need to make your new adapter plate accomodate the starter in the stock OM617 location. |
I am in the process of making one for the 700r4 off a 4.3, same polt pattern as 350. There are no issues with the starter because the 700r4 bell is larger that the benz. So far it looks easy, just figuring out the converter bolts. Both are three lug but the 700r4 pattern is larger, also the pilot is larger. Cheeperjeeper, your t-converter must have a different pilot due to the 2.8 application. About using a different flywheel, these are EXTERNALLY BALLANCED MOTORS !!!!!! Just look at the factory flywheel and you will see the drilled out areas for ballance. And no you can't use one out of a 240 the reason they are externally balanced is the odd # of cylinders. Using anything else must be ballanced to match and bolted in time with the old one with all TWELVE BOLTS! Just my oppinion.

found a site that has an adaptor to a s 10 700r4 plate converter starter i think its around a $1000 seem kinda expensive im wanting to use a combo for a trail rig and are looking to find the right combo any ideas bendtsen's is who makes the 700r4 kit

There is a lot of debate on whether the MB motors are internally or externally balanced. Even the 240D flywheels are drilled for balance - and as you pointed out they are a 4 cylinder - not a 5 cylinder. People who use the 240D flywheel to install a manual tranny almost all seem to have some vibrations at certain speeds, but that may just as well be due to the fact that they are so much lighter than a 300D flywheel. The one off the 240D only weighs something like 24 pounds. Those who use the heavier 300D flywheel never seem to have these vibration problems. Regardless of whether the engines are internally or externally balanced, others who have put a 50 pound flywheel off an AX-15 on the MB crank have not experienced the vibration problems that people using a 240D flywheel all seem to have. This would seem to be evidence supporting the theory that the vibration problems with the 240D flywheel have less to do with imbalance and more to do with not having enough rotating mass to dampen the vibrations. I'm of the persuasion that the drilling of the flywheels was done to fine-tune the balance of the entire rotating assembly, rather than as an external primary balancing. I also don't recall there being 12 flywheel bolts - I thought it was just 6. But I could very well be wrong since it has been over a year since last time I looked at one separated from the tranny. |

Yeah the 2.8L with the 700R4 has a 7/8" diameter x (approximately) 1-1/2" long pilot. Seems to me that as I recall, the pilot on the MB t-converter (and the pilot hole in the MB crank) is bigger than that. No biggie - even if you're using a 700R4 with the 350 bell housing/bolt pattern, you can still use the t-converter from one with the 2.8L bell housing/bolt pattern. As long as you get a low enough stall speed.
That is true to some extent. The factory flywheel for the manual trannys are drilled for balance, but a lot of the MB guys claim that it is mainly to balance the flywheel itself - because a couple of ounces removed by drilling a few holes in the edge of a 38 pound flywheel isn't enough by itself to significantly affect the balance of the rest of the motor. There is also the fact that not all 300D flywheels are drilled the same. There is a lot of debate on whether the MB motors are internally or externally balanced.

Hulkgreen,
don't worry, the AX 15 will withstand the power without any problems I have the stock 2.5TD Jeep Cherokee Diesel with the stock VM engine. I also have bigger injectors and an engine power of 140hp and 340Nm torque. The AX 15 takes it all. |
Have you confirmed that the AW4 will work with your setup? I'd be interested in a future build to replace this 4.0

The trouble with the AW4 is that it is electronically controlled. While it has its own separate computer - the Transmission Control Unit (TCU) - I believe the TCU gets its shift signals from the main engine management computer. The main engine computer uses signals from the Throttle Position Sensor (TPS) to measure how hard you're stepping on the gas, and the Crank Position Sensor (CPS) to measure engine RPMs. It then tells the TCU to shift the tranny based on those inputs. So, to use an AW4 you have to mimic the TPS and CPS signals and feed them to the main computer and then let the main computer control the TCU to shift the tranny. I may be wrong about the TCU being controlled by the main engine computer, and the TPS and CPS signals may go straight to the TCU, in which case you could do away with the main computer. But even if that's the case, you still have to mimic the CPS and TPS signals so it knows when to shift, so it gets pretty complicated. The GM 700R4 is a good alternative - it is also a 4-speed auto with OD and a locking torque converter, but it can be set up with no computer to mess with because its shifting is controlled hydraulically and with a kick-down cable, and when you're using an old-school diesel with no computer control or sensors, that's a good thing. The only thing you have to add is a switch to lock up the TC - if you want to use the TC lockup. That is normally computer controlled, but can easily be done with a switch. I'm using one behind my GM 4.3L diesel, and my plan for the TC lockup is to use a momentary pushbutton to activate a self-latching relay with a NC brake pedal switch to break the relay latching circuit. That way when I'm on the highway I can just tap the button to lock the TC and it will stay locked until the first time I hit the brakes. It will also allow me to lock the TC in any gear. A simple LED indicator light will light up when the TC is locked |
