    Sorry, I'm not aware of older heads being machined to receive the later pre-coms.....not that the machining would be all that difficult but I'm not sure what all was modified to get the clearances required or whether there were alignment changes.

    Default Pre-Combustion Chambers

    I've been having some problems with the pony on my D2 so I started looking at maybe converting it over to a direct electric start. One of the things in doing the convertion I'd want to do is to add glow plus. In looking through OM's image bucket pictures he says that I did not have the number for the pre chambers for the D2 so I started doing some checking around and I came across this website http://truckengineparts.com/prechambers.aspx. I've pulled the information from the web page and made a table of the pre chambers and glow plugs and which engines they fit.

    No problem OM I'm getting real close to pulling the trigger and doing the swap to the DE. I'm thinking of pulling the engine and setting the flywheel housing up on the mill to punch the hole for the starter. Romain Electric is local to me and they have a listing for the bendix and the DEH, don't know what their price is yet though.

    If I mount the batteries where the pony motor sat, how do I bypass the coolant passages? Looking at the coolant flow diagram they can't be blocked off. I looked through the info OM posted, but I didn't find anything that discusses this issue.

    Taking the pony motor out of the cooling loop and blocking the passages is not a problem. Has no effect on cooling the main. The usual approach is to make the floor of the conversion battery box the block off for the bellhousing then just plate the opening in the cylinder head.

    Thanks OM.
    Doing it as you suggested was my initial thought. Looking at the cooling flow diagram in my engine manual made it appear that there was no other path for coolant flow. So I was unsure of doing it that way.

    Things like this are what makes the internet a great thing.
