Old Version Torque Tube Bearing Carrier

Here is a pre '87 puck. It comes in 2 pieces with a rubber band around the perimeter (removed already). The bearing is sandwiched between the 2 halves.

Use a bearing splitter or wood chisel to separate in between the punch outs. DO NOT hit the punch outs with the splitter or chisel because they will be used once the unit is pressed back together.

Once split use a large socket to drive the bearing out of the carrier.

Install the new bearing part way in one half by using finger pressure. Install the other half by hand making sure to line up the punch outs. Put the carrier in a vise with the jaws protected with wood and press the halves together.

Three punch outs on each side need to be re-set. Use a punch that will fit into the punch outs and give it a wack to expand the end that pulled out when the carrier was split.

Here are the old (split) and new carriers.

The new carriers are one piece and the rubber band is bonded onto the carrier.

Remove the old bearing by using a large socket to press it out.

New bearing is pressed in making sure that the tool used to press the bearing in DOES NOT press on the bearing shield. If it does the shield will be bent inward rubbing against the balls and cage.

I re-install the drive shaft from the front of the tube so the new pucks should be installed with the open end facing the front of the tube. This prevents the bearing from working it's way out when the drive shaft is driven in.

Here is a drive shaft showing that the last two bearings were shot.

New Hybrid Ceramic Bearings with Delrin collars

Here is the front end of the TT with measurements for the nose, bearing number 1 and bearing # 2.

Bearing # 3 is 22" from the rear lip and bearing #4 is 4.5" from the rear lip.

When pulling the rebuilt pucks into the TT, start at front of tube and pull #2 first, then #1.

Pull #3 and #4 from the rear.

Duct tape the threaded rod so the new bearing bushings are not damaged.

I insert drive shaft from the front and coat with anti-seize.

This is a 2" pipe coupler. It fits (with a little filing) perfectly into the TT for pulling the pucks out of and into the TT. 4 large fender washers against one end keeps the threaded rod from going through.

The cap is used when starting the puck in the TT. You can hit it with a small sledge hammer without any chance of damaging anything. ;^)
