(09-18-2013, 05:51 PM)Jetmugg Zeeman - I am very encouraged by your posting. I think I could get the crank adapter made locally as well. It looks like you had a flywheel made with no ring gear, then shrunk on a ring gear at the correct location, right?
If possible, I'd rather use a GM type flywheel, for the availability of heavy duty clutches and pressure plates.
transadapters told me $925 for the same thing he told you $795 for. Their website says $725.
Can you share how the block to bellhousing plate was done? It seems to me that the key to the whole operation is matching the crank centerline to the input shaft centerline. Did you have a mechanical drawing, or very careful measurements, etc? Like I said, this is quite encouraging. I manage a manufacturing plant with a pretty decent machine shop. If I had the correct dimensions, I could make the same kind of plate and then use an off-the-shelf scattershield.
We (my racing partner and I), really want to be able to use this Doug Nash transmission for its durability and ease of changing gear ratios. That's the reason for wanting to adapt to a GM-type trans. This thing can take some abuse and power - probably more than an OEM Mercedes piece.
The weight of a fabricated scattershield isn't an issue, it's more of a hassle with the fitment into the trans tunnel. A hydroformed piece like a Lakewood will be a better fit than anything I could make.
Mark M - how did you align the input shaft and the crank centerline when welding the two transmissions together?
The standard flywheel does not have a ring gear, it sets behind the stock 606 flexplate that starts the engine. It is drilled for a GM clutch.
I dial indicated the bellhousing on the 3/8" adapter plate to the crankshaft by rotating it. I then marked the holes and drilled and tapped them. I reinstalled the bellhousing to the adapter plate and redialed it in to zero runnout and marked the guide pin holes. This was originally made for a Covette ZF 6spd. in a Street Rod. (see pics).
