The Dana 20 can be identified by the center rear output, cast iron construction, and deep oil pan. Like the Dana 18, it uses the Texas bolt pattern to hold the transfer case in place. This is a heavy-duty, gear-driven part-time [2] transfer case with a 26-tooth input gear. The output for the front drive shaft is on the right side and the rear ...
In "4-Lo" mode, the input shaft drives through a 2.72:1 reduction planetary gear set and the front and rear axles are locked together through the clutch pack. This same NV247 transfer case is the foundation for the Quadra-Drive system described below. In 2005 Jeep replaced the New Venture Gear NV247 transfer case with the NV245 transfer case ...
Inside of a 231 New Process Gear transfer case. Part-time/Manual, shift on the fly. A transfer case is an intermediate gearbox that transfers power from the transmission of a motor vehicle to the driven axles of four-wheel-drive, all-wheel-drive, and other multi-axled on- and off-road machines.
From 1976 through 1980, the CJ-7 came equipped with a Dana 20 transfer case, Dana 30 front axle (27- or 31-spline), and a 29-spline AMC 20 rear axle, while in later years, Laredo packages added a tachometer, chrome bumpers, tow hooks, and interior upgrades including leather seats and clock.
Dana differential case #706400 [3] (3.07-3.73) shows in Dana's parts catalog to be Dana 61-specific [citation needed]. The 706040x carrier can be purchased relatively inexpensively and used to install lower gears in a Dana 61 axle, such as when replacing a broken or damaged Dana 60 with a Dana 61 while retaining the factory gear ratio.
Both front and rear differentials were offset to the passenger side for the purpose of lining up the drive shafts with the Dana 18 transfer case. With the transition to the 800A model, the rear axle was upgraded to a Dana 44, with a centered differential mated to a Dana 20 transfer case. Some Scouts from this transitional period use a mix of ...
The rear axle was a Ford 9-inch axle, with Hotchkiss drive and leaf springs; the front axle was a Dana 30, replaced by a Dana 44 in 1971. [11] In contrast to the Twin I-Beams of larger Ford trucks, the Bronco used radius arms to locate the coil-sprung front axle, along with a lateral track bar, allowing for a 34-foot turning circle, long wheel ...
Dana 44 Front axles were known for utilizing locking hubs or a center axle disconnect system. However, a permanently locked-in Dana 44 is not uncommon. The Dana 44 has seen use in 1/4-, 1/2-, 3/4-, and 1-ton rated trucks. The Dana 44 was manufactured in kingpin and ball joint variations, as well as closed and open knuckle variations.
