A Bit of Old and a Bit Of New.

by on Nov.23, 2009, under Uncategorized

A quick update.  Here’s a little video which details combining a little old with a little new.

You may recall, I had a small clearance problem with my motor adapter solution.  The setup needed a spacer to keep the clutch in the correct alignment with the original transmission once the traction motor was mounted.  I finally got the new spacer back from the machine shop, and after a few attempts at assembling all the requisite items in the correct order I ended up with what should be a power system that is good to go.

3/4" Thick Adapter Spacer

3/4" Thick Adapter Spacer

What you’re seeing is the traction motor on its end.  The flywheel adapter is the first thing to be mounted to the motor shaft using a 1/4″ square key to prevent the adapter spinning on the shaft.  Then the spacer goes on, the adapter plate sits on the spacer, the clutch bellhousing bolts to the adapter plate, and the original flywheel (now with no starter ring teeth and some material taken off the backside… no less heavy really) is bolted to the new flywheel adapter.  The flywheel surface is cleaned of all oil and grease, the clutch disc is placed on the flywheel, and the clutch pressure plate is mounted to the flywheel trapping the clutch disc.  Easy…  Took me four times to get that right.  I hope.  These things don’t come with directions.

This should all bolt directly to the transmission with no troubles (?).  Stay tuned.

    How do you get a hold of chennic to buy one of their dc/dc converters

    It was kind of difficult getting a hold of them, but you should contact Sharon at

    In fact, I just purchased one of their DC->DC converters. I was able to specify output voltage, and spec’d 14.5v to match the kind of output a running alternator would generate. It will provide up to 27 amps (400w) of primary power for my 12v accessories, as well as charge the small Odyssey PC625 AGM 12v battery I’m using as a buffer. It ran about $130USD complete with DHL shipping to my door.

    The unit appears much more robust than my Iota DSL-220-30 converter. While the Iota looks like a robust computer power-supply, open to the elements, the Chennic is enclosed in a nice finned, aluminum case. And the electronics board is completely potted for additional weather resistance. Iotas really need to be mounted in enclosed, protected spaces. The Chennic should survive in the engine motor bay.
