- Lubricate the cylinder walls and piston generously with motor oil.
- Rotate ring gaps so they are positioned on opposite sides of the piston.
- Loosen the two screws on the ratchet mechanism. CAUTION: Do not allow the tool to spring open as the steel straps may break.
- Install the compressor over the piston with the ratchet square drive facing upward and tighten until rings are fully compressed, leaving the piston skirt exposed.
- Lower the connecting rod into the cylinder while ensuring rod studs straddle the crankshaft and piston orientation marks face the correct direction.
- Insert the piston skirt into the cylinder until the tool’s dimples stop at the block surface.
- Using a hammer handle or wooden block, gently tap the piston until it is flush with the block.
