How much does a NP205 weigh?

The cast iron housing combined with beefy internals puts this case weight at nearly 140 pounds dry. High-range gearing is 1:1, and the NP205 has a low-range ratio of 1.96:1.

What is the difference between a 203 and a 205 transfer case?

The NP203 and NP205 have the same reduction ratio of approximately 2.0:1. The NP203 is chain driven, the NP205 is gear driven… based on advertised ratings, the NP203 and NP205 are very similar to each other in strength.

Is the NP205 chain-driven?

In the early days of 4x4s, transfer cases like the Spicer 18, Dana 300, and NP205 were the norm. By contrast, these transfer cases use aluminum cases and are chain-driven with planetary gears of varying size (depending on the application).

Can I use ATF in my transfer case?

Transfer cases may be filled with gear oil, automatic transmission fluid (ATF), or specialty lubricants. It is important to regularly inspect the transfer case for any damage, leaks, or other concerns.

What years did Chevy use the NP205 transfer case?

The NP203 was used from 1971 to 1978. This transfer case was mated to the TH350, TH400, and SM465 transmission. In 1981, GM introduced the NP208 chain-driven transfer case. The NP208 also has a circular bolt pattern, and had either a 27 or 32 spline input.

Is a 208 transfer case good?

The New Process 208 is a chain-driven transfer case. This transfer case is a good gear box with a low ratio of 2.61:1. The weakest part of this transfer case is that the shifter fork wears easily, causing shifting problems. This transfer case was used in production vehicles manufactured from GM, Dodge, and Ford.

What’s the difference between the NP 203 and NP205?

Couple things… The NP203 and NP205 have the same reduction ratio of approximately 2.0:1. The NP203 is chain driven, the NP205 is gear driven…based on advertised ratings, the NP203 and NP205 are very similar to each other in strength. The NP203 uses a much wider chain then most of the “normal” part time tcases because it is under load all…

What are the features of a NP205 offroad?

The NP205 is identified by several features: 1. The transfer case is one piece of cast iron. There is a short bearing retainer/output housing at the tail of the case, and aluminum bearing retainers/seal retainers at the front and rear outputs but the working parts are all in a single iron housing.

When did the NP205 transmission case come out?

The NP205 is a single piece cast iron case with helical gear driven transfer case with a 1.96:1 reduction in low and 1:1 in high range, it was used in a variety of applications from 1969-1980 in Dodge, Ford, GM.

How big is the idler shaft on the NP205?

There is a small idler shaft cover on the back of the 205 with 3 small bolts holding it on. This is somewhat unique among transfer cases. 3. The overall length of the NP205 (in fixed output yoke versions) is about 12-13″ from the front of the case to the center of the output yoke. 4.
