While it looks slightly similar to a 205, the gear box on the front and the longer tailhousing are the easiest giveaways.

It will list the model number, the manufacture date and the gear ratio. The model tag (if it still exists) will be found on the front of the chain case above the front output shaft. The shifter is a somewhat complicated box that actuates the 2 levers on a single shaft on the side of the range box section of the 203.Ĥ. The overall length is about 22-23" from the face of the case to the rear output yoke centerline.ģ. The front 2 sections are cast iron, the back 2 sections are typically aluminum.Ģ. The transfer case is made up of 4 sections bolted together, a range box (the gear reduction we use for the Doubler kit), the chain case which houses the chain drive to the front driveshaft output, the differential housing, and the output housing.

Shift positions are: High, Lo, High Lock, Low Lock and Neutral.Ī popular modification to the 203 was to install a "part time" kit to eliminate the differential and slightly increase fuel economy. This was made possible through use of a differential in the back of the 203 that let the front and rear driveshafts turn at different speeds as just as a diff in an axle lets each axle shaft turn at a different speed.įor off road use, the 203 had a "lock" position in which the differential was locked making the front and rear outputs spin at the same speed (like a normal part time transfer case).

The NP203 were originally a full time 4WD case, meaning all 4 tires receive power at all times.
