T80850 Main Bearing Cap Nut Runner Tool
This 3/8" square drive tool engages the main bearing cap nut utilizing two balls 180 degrees apart. The tool is applied to the nut by pulling the knurled collar back allowing the balls to recede into the tool. By turning the tool these balls engage the nut and the collar can be released locking the tool to the cap nut. The tool can then be turned by using a 3/8" palm ratchet.
