Piston and Rod Disassembly with Hydraulic Tool
1. Remove the two Allen set screws from the piston nut and discard.
2. Clean and oil threaded hole in rod. Set up torque tool with proper adapter endplate, dowels, and
puller-bolt required for the particular piston and rod. The tool comes with two different size pullerbolts,
four dowel drive pins (two pairs of different sizes to match each puller bolt), and three
adapter baseplates. A change in puller-bolt size requires a change in dowel drive pins as well.
