Diferencias entre transfer del mismo modelo

vitoco · 03-07-2007, 18:29:48

Hola estimados, tengo la siguiente duda.

Cual es la diferencia física entre transfer del mismo modelo, pero de distinta aplicación o vehiculo (dodge, jeep, gmc, etc.).?
Estoy viendo en particular la NP231, de la cual hay NP231 D, NP231 J, NP231 AMC ó NP231 C.

He estado revisando en google y TA pero no he encontrado mayor detalle, solo que son para distintos vehiculos.

Saludos,

The Jeep NP 231 transfer case was introduced in the 1988 model year. Jeep's YJ Wrangler and the XJ / MJ Cherokees with the Command Trac option were the first models to feature it. The 231 was initially tagged as the 231AMC, and as ownership of AMC was taken over by Chrysler, it was later designated as the 231J. This transfer case was later to be called the NVG (New Venture Gear) 231J. Despite the different nomenclature, they are essentially the same transfer case, with the bulk of their parts interchanging.

This transfer case is identified by its red and silver tag on the rear of the case. They are also easily identified by appearance. They feature a six-bolt front face.

There are Chevy & Dodge versions of the 231. The GM versions use a five-bolt front face that is incompatible with the Jeep and Dodge six-bolt styles. The Chevy versions also use long factory adapters and have no support for improvements - particularly in shifter upgrades and tailhousing upgrades like those available for the Jeep versions.

The important variations to look for in the 231 transfer case are in the input gear. The 231 comes in 21 spline and 23 spline versions with long, medium (rare) and short variations.

The long shafts protrude 2.1" from the front mounting face of the transfer case. The short version protrudes 1.2". The rare medium shaft protrudes 1.7". You should be careful when swapping any of these gears due to different bearing widths and gear teeth. The following chart shows how to determine which input gear you might have by transmission. It is always recommended to verify first hand if possible.

Because of differences in the cut of the gear, as a general rule; one should not interchange pre-'95 gears with post-'94 gears. These years are not hard and fast delineations. If one is not absolutely certain, disassembly and inspection is required.

Note that some transmissions change spline count. The Peugeot BA10/5 had both 21 or 23 splines. The AW4 had 21 splines through 1990. In 1991 (the same year the 4.0 HO was introduced) the AW4 splines increased to 23.

Generalmente se diferencian en los ejes de entrada y el tipo de salidas , Slip Yoke , Fixed yoke , a veces reduccion, y dependiendo de la aplicacion traen componentes internos reforzados.
