I just checked there is no SAE 10, 10 refers to a 10 inch over center clutch.

In order to get the right match you need to know what your depth is from the face of the Cummins flywheel to the surface of the flywheel housing. Did Jim or Bill give you the proper dimension? I think for any of the adapters whether GM or Chrysler the depth should be 2.12. If you have a shallow SAE 4 (Aluminum Housing) you will have a depth of .99. This case you will need a 1.13 spacer. If you have a deep (cast Iron) housing the depth should be correct. There is also a standard housing that is between these two but rare.

The Cherokee is a 1990 with a 4.0 Liter engine and a AX-15 transmission. The engine ESN is 68006096. I had to buy the SAE #4 long flywheel cast housing Option, FH30006, PN C6204214320, as the B3.3 engine came with a short aluminum housing. Do I need to buy a deeper flywheel? I have a source that will trade me straight over for the aluminum housing and shorter flywheel for the cast housing and deeper flywheel. I just have to pay for shipping both ways. Unfortunately, I already bought and installed the long flywheel housing and wouldn't need another long housing. The flywheel number from my source is PN C6205314211. Would this work? I have a call into Cummins West to see if I need a deeper flywheel and what number. I believe the engine was for a generator.

Thanks for your input and help.

Guys,

I was doing some checking, and found the NMC Wollard, in WI. Uses this engine as an option in a number of pieces of equipment. They have a bellhousing adapter to the Ford C6 Auto. I know this is a 3 speed, and not very desirable, but that blot pattern is still used for a number of other transmissions.

I have a call into them to see if they can get me the part number, and if it a repair part that can be ordered. I wonder if I can order the eng and trans together. Anyway just a thought.

What are your plans for engine mounts/isolators? With the Cherokee being unibody, I'm wondering about diesel engine vibration being transmitted to the cabin. Have you considered the liquid filled mounts from a 1989 - 1993 six cylinder F-150/250/350?

www.rockauto.com has them for $19.

95z28a4,

I like the idea of liquid filled mounts, but I don't know if enough room exists. I'll have to make some measurements. I had planned on using the Dodge truck mounts TDIwyse used, but I am open to suggestions.

Thanks,

Bob,

I was looking at the Wollard product. I was going to bid on a Perkins engine from Government Liquidation, but the engine was pulled from the auction. Wollard uses many different engines, gas and diesels. The transmissions are geared for low speed, high torque to power aircraft towing tractors for the military and civilian use. You might be able to buy an adapter from their transmission remanufacturer.

Here's a URL to the PDF from Sage Parts who remanufactures the trannies.

Here's the price list: http://www.creg-gse.com/html/c6_tranny.html

Wollard also uses a Allison automatic AT545 as an option, but I don't know if Sage Parts rebuilds the Allison. Further looking, they do sell the Allison, but you'll have to call for prices.

Here's a source for some Allison take outs:

They might have adapter plates for the Ford or Allison.

Good Luck,

The Dodge/Cummins 6BT weighs approximately 1100 lbs ~ twice the weight of a B3.3T. While the Dodge truck mounts may work OK, I'm thinking mounts designed for an engine in the 500 - 600 lb range would be "softer" and do a better job of absorbing/isolating vibration.

Here's another liquid filled engine mount from a FWD 1997 - 2005 Chevy Venture van. It looks like it may be adaptable for a transmission mount in a RWD vehicle.

www.rockuto.com has them for $30.


Here's a link to a 1998 ZJ build with a Cummins 4BTA using the original P30 step van engine isloators. The P30 isolators are similar in design to the Ford mounts, but a little larger. He has some pics of his mounts. Maybe it'll help you with your XJ.

What you have will work FH30006/FW30005. My engine came with FH30001/FW30001 it weighs 52 lbs less than that setup and ha less rotating mass. Needed a spacer though. If weight is not an issue forget it. Why didn’t you go all Chrysler? The 3.9 bell housing will fit with PC SAE4 to Chrysler Small Block 727 adapter set. With this you can keep the stock slave and master. No GM to AX-15 adapter. Check out pics...

BigBlue, that rockanddirt link was fantastic! Oh man, the possibilities . . .

TDIwyse

I like the big C on the valve cover! Is that a plastic badge you put on there?

Can you expand on the 3.9 bell housing comment?

I'd also like to know where/what/how you did the block heater.

Thanks for the pics.

TDIwyse

OK, I see in your photo link you say it's a Dakota 3.9 bell housing. I was thinking 4bt 3.9 . . .

Macet

The heater is a 4b-6b heater #3975628 I used a cast 3/4npt to 1 inch bushing brazed to a plate with holes drilled. Hasn't passed leak test though. Got to get it running, but should be ok. If you would like to try I can get you some dimensions. Also the link below may have the heater cheaper. I am going to use Cummins cord p/n 3923050 that's around 30.00. I think the whole thing will work better than the heater that is made for that engine (cup plug type) I don’t like then.

Thanks for the info. My jeep lives in an attached garage and I have no where to plug in at work so i'll probably hold off on doing that. I'm not familiar with the cup plug style you mentioned. What's that look like?

95Z28A4,

thanks for the info on the motor mounts. I just bought a Wonder Bread truck with the Bt3.9 and Ford manual tranny and could use that info if needed.

I am open to different ideas. Keep them coming.

Macet,

Hey, where were you when I needed you! I went with the GM to AX-15 due to limited information available. Most of us were inspired by TDIwyse. Why fix it if it aint broken. The Chrysler route seems to be the cheapest. Could you post some more info on the Chrysler conversion? I assume you went with Pheonix 727 adapter, to a 3.9 bell housing that bolts directly to the AX-15? Doesn't the Dodge Durango use a AX-15? You mentioned a spacer. Were did you install the spacer and what was it designed for?

Thanks,

Chris
