There are some common misconceptions about the way the shifters on a NP205 work. The biggest is that there is a "4wd lever" and a "hi-lo" lever. This is false. The 205 has one shift rail that controls the front output shaft and one that controls the rear output shaft.
The 205 is a part time 4WD case, meaning when it's in 2WD the front driveshaft will not receive power. It has 4 stock shift positions, 2WD Hi, 4WD Hi, Neutral, and 4WD Lo.
Learn about the NP205 transfer case diagram and how it functions in off-road vehicles. Understand the various components and their roles in transferring power to the front and rear drivelines.
The NP205 transfer case is a heavy duty gear driven transfer case in a cast iron case. The NP205 gear driven transfer case is considered by many to be the king of bulletproof. It was supplied in many GM, Ford, International and Dodge full-size trucks.
They include stronger shafts and yokes, shifter enhancements, and lower gearing options. Another big benefit of the NP205 is the fact that it can now be fitted to many more powertrains.
The NP205 is a gear driven transfer case used in a variety of Ford, GM, and Dodge pickup applications from the late 1960's through the early 1990's. It is widely popular and praised for its strength in rugged offroad applications.
DO NOT spin dry bearings. Remove all traces of gaskets from surfaces. Inspect teeth of all gears for excessive wear or damage. Replace gear(s) if these conditions exist. Check for sliding clutch wear on engagement side. If wear exists, use opposite side of clutch in reassembly. Both sides of clutch are identical.
In 1971, New Process introduced a model NP203 (chain-driven), and NP205 (gear-driven) transfer case. Identifying the NP203 and NP205 comes down to knowing what you're looking at. Both of these transfer cases used various input splines.
