How strong is a 205 transfer case?

This transfer case is considered by most people to be nearly indestructible in most applications. 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.

How can you tell a 205 transfer case?

Identifying an NP205 is relatively easy: It has a cast-iron case and center idler shaft with a nut on the front and a three-bolt cover on the rear, is about 12 inches long, has a center rear output, and usually has an ID tag above the front output shaft.

Are all NP205 transfer cases the same?

Are all NP205 the same? The NP205 input gears, no matter what vintage or model, are always the same internally. This allows you to swap the input shaft between the various model transfer cases. One difference that must be taken into consideration is the front input shaft bearing.

What years did Chevy use the 205 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.

What fluid goes in a NP205 transfer case?

Registered. As has been discussed in previous posts, NP205 transfer cases require 80-90wt Gear oil.

What kind of transfer case does a GM Process 205 use?

NP205 originally coupled to a SM465 or TH400: Found in 1985-91 vehicles, this transfer case has a long stick out of approximately 3.50″, and a female 32 spline input. The bolt pattern is a circular-six configuration. This transfer case uses a larger front bearing than the 10 and 27 spline transfer cases.

Where is the transfer case on a NP205 offroad?

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. 2. There is a small idler shaft cover on the back of the 205 with 3 small bolts holding it on.

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.

When did the New Process 205 come out?

The NP (New Process Gear) 205 transfer case was a popular unit used by all the Big Three automakers, specifically found in 1969-1993 Dodge trucks, 1974-1979 Ford trucks and 1969-1980 GM vehicles.
