Reasonably Priced Crawler Box for LT230

So who is interested in an adaptor to fit the Borg Warner 1339 (Jeep Quadratrack) T-case to the LT230 T-Case as a crawler box? Provided the adaptor could be made for a reasonable price this would be the cheapest way to get a strong bolt-on crawler box.

Bill Larman (who has fitted these crawler boxes to both series and LT95 t-cases) is looking to get adaptors manufactured in Australia (if there is enough interest).

I estimate (this is my guess only) that the adaptor would be $500US or less (but you need to source your own BW1339. The only downside is (I believe) the kit will have to also include an adaptor to use a series handbrake drum on the LT230 (otherwise the crawler won't fit).

For more details, and to post if you are interested, click here (start reading at the 6th post down).

I have no personal interest in this venture (other than I want a reasonably priced crawler box for the LT230 to be available).

AFAIK there aren't any CAD files. Bill, the guy who has built 2 of these adaptors before, is very much an old-tech (pen and paper) kind of guy. However, maybe he can do some pen and paper drawings and someone can convert them to CAD.

That shouldn't be a problem. Right now I am taking an autoCAD class and that is pretty much all we are doing: converting hand written diagrams onto the computer.

If you can get the specs to madcowdungbeetle, him and I could probably have that mofo on the puter' in no time.

Oh, when you send it, send two copies and two bottles of scotch

I would think the best way would be to get a roamerdrive and swap the planetary gearsets. All the other engineering is done. Would be a good prototype, then maybe make a deal with roamerdrive to buy select parts (case, linkages, the part that sticks into the transfer case, etc). But overall, except for the gear ratio, EVERYTHING is there. Even getting a 1.50 or 2.00 gear ratio reduction would be huge. Not like we need to go all 22re 598379482:1 crawl ratio.

I was just looking at a cutaway for the Fairey. Kinda wish I had kept my old one. I think turning it into an underdrive would be semi-simple assuming I could find someone to cut a new countershaft for me and weld on the case. That said old series overdrives are junk. Mine ran on metal shavings.
