UNIVERSAL JOINT-SINGLE CARDAN
DISASSEMBLY - WITH SNAP RINGS
NOTE: This procedure describes a propeller shaft equipped with a cardan joint in the tube yoke. For propeller shafts equipped with a companion/slip yoke, repeat the steps to remove the remaining cardan joint.
1. Tap outside of bearing cap with a drift to loosen snap ring.
2. Remove snap rings (1) from both sides of yoke.
3. Position yoke with the grease fitting if equipped, pointing up.
4. Position a socket (2) with a inside diameter large enough to receive the bearing cap, beneath the yoke on a press.
5. Place another socket (2) with an outside diameter smaller than bearing cap on the upper bearing cap and press (1) the lower cap through the yoke.
NOTE: If the bearing cap will not pull out of the yoke by hand after pressing, tap the yoke ear near the bearing cap to dislodge the cap.
6. Pull bearing cap of the yoke.
7. Turn yoke over in the press and straighten the cross (1). Press the cross until the remaining bearing cap (2) can be removed.
CAUTION: If cross or bearing cap are not straight during removal, the bearing cap will score the walls of the yoke bore and damage can occur.
