Ring Gear Removal and Installation

Using a dead blow hammer lightly pound on the top edge of the ring gear until the ring gear pops off. It only took me a few blows evenly spaced around the ring gear.

The ring gear will need to be pressed onto the carrier and then drawn in using the ring gear bolts. Our first step in that direction is to fabricate a few pieces so that while we are in the process of seating the ring gear the bolt holes line up. You can be creative or you can follow the pictures and use a few stray bolts like I did.

As you can see in the picture the ring gear slides over the carrier but does not seat without being pressed further down.

The picture on the left illustrates exactly what we do not want; the ring gear pressed on without the bolt holes being lined up. In this case we would have to remove it and repeat the installation. The picture on the right illustrates what we are looking for. We have to have those bolt holes line up.

One method, illustrated on the left, is to use a smaller diameter bolt to guide the ring gear onto the carrier so the holes line up. Besides using smaller bolts, you can use your imagination to come up with another piece that can guide the ring gear on.

Place the ring gear in a pot of boiling water for a few minutes. We want to heat the ring gear slightly so that it will slide easier over the carrier flange. If you have access to a press you do not need this step.

Set the bolts (or other fabricated pieces) in place so that the ring gear can be taken directly from the pot of water to the carrier.

Set the ring gear on the carrier flange, line up the bolt holes, and apply a bit of pressure downward. The ring gear should slide most of the way down onto the carrier.

Install five ring gear bolts and tighten them in sequence so that the ring gear is drawn toward the carrier evenly. You will need to brace the carrier as shown in order to apply torque to the bolts. The bolts should tighten very easily, drawing the ring gear against the carrier flange very gently.

Tightening the five ring gear bolts evenly to draw the ring gear against the carrier flange. Notice that I braced the carrier by placing a piece of pipe through it and resting that pipe against a stationary object (in this case a vice.) If you are not rebuilding the Traction Lok you will need to find another method of bracing the carrier.

Remove the ring gear bolts and turn the carrier upside down so that any water in the bolt holes can drain. Allow the ring gear and carrier to dry completely.
