Overdrive Differences

Will shared pics that show some of the differences between a Warn overdrive with a Husky overdrive. Regarding finding Husky parts, my best guess for parts would be Herm Tilford.

Will writes, “A little while back there was a discussion on the different overdrive units. There where several different units produced and maybe others but the ones I’ve seen are Warn, Dualmatic, Saturn, Husky and ATV overdrives that all looked similar. Saturn is a direct decedent of the Warn as Advance Adapters purchased the tooling from Warn to make the Saturn. I don’t know much about the Dualmatic or ATV except ATV is still produced as is Saturn.

Anyway I had mentioned that the Husky had a different angle to the planetary gears, Sun gear and bowl gear than Warn. These pictures show how the Warn had much more tooth angle than Husky and as such these parts do not interchange and Husky parts are near impossible to find.”

Unusual Auxiliary Transmission … Can Anyone Identify It?

UPDATE: While still unidentified, we have learned thanks to the Dutch_Jeeper on the CJ-3A page that the auxiliary transmission is an “under-drive” rather than an overdrive. He pulled this out of his CJ-3A, then disassembled it.

You can learn more and see more pics here: https://cj3apage.com/Forum/index.php?topic=2318.msg19546#msg19546

Sierra Overdrive Brochure and Instructions

• CATEGORIES: Advertising & Brochures, Documents, Features, OD Other This site contains affiliate links for which I may be compensated.

I found this cool and rare brochure for the ill-fated Sierra Dana 20 overdrive on eBay. It’s printed on 8.5″x11″ paper, so the marketing budget must have been tight (as I understand it, working capital was an early issue, which played a part in the demise of the company). A few years ago there was a post of an article that also highlighted this rare overdrive.

The following instructions and schematics were tucked inside the brochure above:

1980 Overdrive Article from Pickup, Van & 4WD Mag

• CATEGORIES: Features, OD Other, OD Borg Warner/Rancho, OD Saturn/Warn, Old Images This site contains affiliate links for which I may be compensated.

UPDATE: Here is a brochure and some directions/schematics for the rare Sierra Dana 20 Overdrive.

sierra-overdrive

The Sierra Overdrive was designed to mount to a Dana 20.

In November of 1980, Pickup, Van & 4WD Magazine published this article on overdrives, which includes several I hadn’t heard about. This series of article images comes from Christian Harrison (and thanks to Marty Tilford for spotting it). The scans aren’t perfect, but are mostly readable. You can find a similar article at the Four Wheeler Network.

Particularly interesting to me is the Dana 20-mounted Sierra Overdrive. Willie Worthy of Four Wheeler was involved in the development of it, but noted that a lack of capital doomed it.
