Description

To make it easier to install a new front output shaft seal in a NP246, NP261HD, NP263HD, NP261XHD and NP263XHD transfer case the team at Merchant Automotive developed this CNC-machined billet aluminum seal driver. The driver features a durable anodized black finish with a laser etched logo and part number to make them easy to identify when sitting in your tool box.

FAQ:

What kind of hammer should I use with the seal driver?

For best results use a rubber or plastic hammer such as a dead-blow hammer. Do not use a metal hammer as the tool could be damaged.

How do I set the seal depth while using the seal driver?

The Merchant Automotive seal drivers are precision machined with positive stops to properly index and set the depth on your seals when properly used.


Can I replace the front output shaft seal with the transfer case installed in the vehicle?


Yes, after removing the front driveshaft the seal can be removed and replaced without removing the transfer case from the vehicle. Some people feel that it can be easier to remove the transfer case and replace the seals on a workbench though.

Front Seal Driver

Tony - | 10/17/2019 12:01:00 pm

The front output shaft seal on many NP transfer cases, GM part number 12474947, is a two piece design which requires driving the outer flange and the inner sleeve at the same time. This tool from Merchant Automotive does the work of the OE Kent Moore tool J-43484 and is less expensive than it or any other option I've found. It is made of solid metal assuming aluminum and has a center hole if you want to attach a driver handle, though it works fine on its own.
