ISB 170/NV4500 flywheel

I'm trying to install an NV4500 behind an ISB170 that had an Allison.
The flex plate is a 159 tooth ring gear and is about 17" in Dia.
I cant find a flywheel to replace it.
Does anyone have a part # for a suitable flywheel?
Will I need to also replace the starter?

Thanks
Randy

Are you trying to use the SAE engine adapter that the allision was mounted to???

If that 4500 is from a Dodge. Use a Dodge engine adapter and flywheel.

I was going to use the same adapter and have a bellhousing that bolts on with the correct spacing but would have to make an adapter from the bellhousing to the NV4500 which I also had to do on my Isuzu / Dakota swap.
Just trying to find a flywheel.
I can find 159 tooth ring gears on Ebay but they dont say what the flywheel part # is.
My logic says if I can buy the ring gear I must be able to buy the flywheel!!!

If I had known the rear gear ISB would just take a stock Dodge adapter I would have gone that way.
Maybe time to rethink.

Your trying to add more fab work by trying to use that SAE engine adapter. If that 4500 is out of a Dodge truck. Just use the engine adapter and flywheel setup from a Dodge. It would make the swap easyer on parts.

If the 4500 is from a Chevy, find a Dodge bell housing and replace the input shaft.

After looking at the rear of the ISB 170 I assumed that it would not work.
The rear housing has a breather coming out of it and the shape does not look like the 4Bt / 6BT stuff I have seen.
Yes if this works its the way to go but I have been all over the net for the last three months trying to find info on the ISB170 and no one seams to have played with them enough yet.
If you can assure me the 6 cylinder parts will bolt on then I will buy the stuff this week but no one has been able to say they will fit.

Thanks
Randy

Yes as far as I know all the 4 cylinder ISB's are rear gear.

Rear gear leaves you with the SAE engine adapter. Any good clutch shop can most likely set you up with the correct flywheel/ clutch setup. I know South Bend clutch does about any type of clutch from N/A old stock up into semi class clutches.

Now why the 4500 trans??

There are many better trans options when your working in the SAE #3 adapter.

What are you building???

Yes Peter @ South Bend is building me a flywheel and clutch and Monte from blumenthalm is supplying the new trans with the correct input and output shafts.
I used an NV4500 in my 1999 Dodge Dakota/Isuzu 4HF conversion and like the trans.
Dodge Dakota Diesel Conversion
This time its a ISB 170 into a 2008 Dakota 4X4 Quad cab.
Not a lot of room for a larger trans under that truck.

Ok that explains the 4500.

Most all of the SAE #3 trans would be to big for that trans tunnel.

I have one of these industrial engines. The research I yielded said that the entire rear-gear setup and bell-housing is difficult to go away from. You have to change the crank, cam, and get all the front pump mount stuff added back on. Perhaps it is just my particular engine.

On mine...it isn't as easy as just acquiring the Dodge parts (trans/bellhousing), but it is a major change.

That's the same as mine.
I think the 4BT people just assume these new engines are the same as the older ones.
I had a flywheel made by South Bend who also supplied the clutch.
It should be here next week.
Also have a new NV4500 on its way so next month it should all be bolted up.
I found a thin bell housing from an Isuzu NQR with the correct SAE #3 pattern and will just make a simple adapter plate between it and the NV.
