Retaining Ring Removal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for some technical advise. While cleaning up my NP205 transfer case, some sand got into the bearing where the adapter fits up to the transmission. I was able to remove the outer ring with ease, but the inner ring is way to strong and doesn't have enough lip to open with the same flat head screwdriver technique. Hopefully the pick will illustrate the location of the problem a little better.

Since the 10 cent method isn't working, is there a special tool I can buy to open this ring up? If so where can I get it? Thanks in advance

I USED A SET OF PISTON RING REMOVAL PLIERS TO REMOVE MINE. WORKED LIKE A CHAMP.

The correct tool is called retaining ring pliers. If you are going to do much work on trannies or t-cases, invest in the best set you can find. They are basically the same thing as those piston ring pliers, except bigger and stronger, and the tips are designed to get on the rings from different angles depending on the access you have.
