Disassembling the Piston

If no oil has leaked into the drive side of the wrench, it is not necessary to fully disassemble the piston rod sub assembly. Simply replace the outer piston seal [9].

Inspect the bore of the piston rod end [4]. If the piston rod end is in good condition, there is no need to remove it.

To fully disassemble:

  1. Unscrew the piston rod end [4] from the piston rod [6].

  2. Clamp the piston sleeve [5] in a vice with the special vice grips.

  3. Use the piston tool to unscrew the piston [8] from the piston sleeve [5].
