For years Toyota Land Cruiser enthusiasts have dreamed of finding a durable, low-geared transfer case able to withstand rugged conditions. With the introduction of the Advance Adapters Orion case, their dreams just became a reality. The Orion offers the strength of cast iron coupled with the rock crawling capability of a 4:1 gear set.

Besides the cast iron case and lower gear set, the Orion has other additional benefits over a stock transfer case. Benefits include a larger 34mm idler gear shaft; wider needle roller bearings for improved load distribution, and a fully gusseted idler shaft area on the case. This revolutionary transfer case will eliminate any downtime due to case failures. There is no need to modify either driveshaft’s for the installation since the length and dimensions of Orion are nearly identical to the stock case.

The Orion replaces stock transfer cases in Toyota Land Cruisers built between 1963 and July of 1980. Stock transfer cases built during this 18 year span are either a 10-spline case coupled with a 3-speed tranny or a 16-spline case coupled with a 4-speed tranny. Prior adaptations of other transmissions using Advance Adapters conversion products will also be compatible with the Orion transfer case.

This case replacement has the same external width, eliminating driveline modifications. The casting contours that outline the low speed output gear will position the drain plug approximately .500” lower on average. The new low ratio gear set supplied replaces existing gear sets except for the PTO gear or PTO spacer sleeve.

The Orion kits come with a new cast iron case, four new gears, a new 34mm cluster pin, and a complete gasket bearing and seal kit. This transfer case, however, is not a complete “ready-to-bolt-in” unit like the Atlas. The transfer case does require the use of your stock front and rear output shafts and housing .The new unit also requires the use of the stock P.T.O. gear and inspection covers.

The Orion transfer case requires the complete removal and disassembly of your stock Toyota transfer case. Once the stock transfer case is removed from the vehicle it becomes a donor for the new Orion case. This kit requires that you reuse your stock fasteners, front& rear housings, retainers, shafts, shift fork, clutch sleeves, and cover plates from your original transfer case. You are supplied a full rebuild kit to replace all bearings, races ,O-rings, seals, and gaskets. Shims for the rear output shaft retainer are also supplied to set the bearing pre-load. Do not discard shims, washers, sleeves, and spacers from your stock yokes and shafts. Although the instruction sheet provided with your new transfer case will initiate the steps to install the Orion, it is advised that you also obtain a shop or repair manual that covers your specific application.

Best thing for your FJ40,60...

Wow what a difference, I should have done this a long time ago, I have much more control with this unit in and I can step on the brakes and really lug it down. I am running on propane as well.
One more thing, the directions are direct and to the book, I only had to call AA one time to make sure the delivered case was already put toghther. I also purchased the twin stick, and I like it, not love it.
Love it, you will too.
