NV4500 OUTPUT SHAFTS GM & DODGE
GM 32 TOOTH 4WD OUTPUT SHAFT: On all NV4500s that were equipped to a GM 4WD transfer case, you will find that the output shaft has 32 teeth. The adapter housing that is mounted to the back of the transmission case is 8-1/8" long. On the inside of this tailhousing, you’ll either find a vibration damper on the output shaft or a steel sleeve. Most of our transfer case adapters will require the damper or sleeve to be removed. We couple to the 31 tooth spline located under the damper or sleeve. In order to remove the vibration damper or sleeve, you must use a special socket. This socket will be required in order to remove the nut because this nut is put on with 275 ft./lbs. of torque. On transmissions with the damper, a gear puller will be required since the damper is a press fit to the output shaft. On all applications that require the removal of the damper or sleeve, we will provide a custom set collar that must be installed on the output shaft to retain the 5th gear into position. 52-0204
GM 35 TOOTH 2WD OUTPUT SHAFTAll GM NV4500s that were used in 2WD vehicles will be equipped with a 35 tooth output shaft. Located on the end of the shaft will be a large balancer type yoke. We do not make any transfer case adapters to couple to this output shaft.
DODGE 23 TOOTH 4WD OUTPUT SHAFT On all 1993-2000 NV4500s that were equipped with Dodge 4WD transfer cases, you will find that the output shaft has 23 teeth. The adapter housing that is mounted to the back of the transmission case is 6-1/4" long. On the inside of this tailhousing, you’ll find a locking nut that secures the 5th gear to the main shaft. This stock nut has undergone some design changes from the manufacturer because they have been known to loosen after time. Our adapters do not require the removal of this nut; however, you might want to make sure the nut is still properly secured. Most of our transfer case adapters do not require any modifications to the shaft or stock tailhousing. 52-0205
DODGE 29 TOOTH 4WD OUTPUT SHAFT (for Heavy-Duty & 2001 Standard Duty transmissions)On all Cummins diesel Dodge Heavy-Duty 4WD NV4500s and 2001 & up Dodge Standard Duty 4WD NV4500s, you will find that the output shaft has 29 teeth. The adapter housing that is mounted to the back of the transmission case is 6-1/4" long. On the inside of this tailhousing, you’ll find a locking nut that secures the 5th gear to the main shaft. This stock nut has undergone some design changes by the manufacturer because they have been known to loosen after time. Our adapters do not require the removal of this nut; however, you might want to make sure the nut is still properly secured. If you have one of these transmissions and plan on changing the output shaft to one out of the other model NV4500s (i.e. a GM NV4500), you will also be required to change the 5th gear assembly since it will not fit on the new main shaft. A new nut to secure this 5th gear will also be required. 52-0206
