Cummins Special Service Tools
Includes cylinder liner press/puller, piston ring compressor, and connecting rod guide pin. Due to the extreme precision of the water seal rings and piston ring grooves in Cummins high-horsepower engines, forceful installation can easily cause seal damage or cylinder wall scoring.
Core Features & Advantages
⦁ Cylinder Liner Tool: Ensures the cylinder liner is pressed into the engine block vertically and smoothly, guaranteeing that the water seal ring remains undamaged and the liner protrusion height meets standard specifications.
⦁ Piston Installation: The piston ring compressor perfectly compresses all four piston rings; the connecting rod guide pin (guide screw) acts as a "track" during the installation of the piston and connecting rod assembly, guiding the piston smoothly into the cylinder liner and effectively preventing the connecting rod bolts from scratching the crankshaft journals.
⦁ Usage Tips: Before installing the piston, the piston ring gaps must be staggered according to the service manual requirements (typically 90 or 120 degrees) and positioned away from the piston pin and the direction of side thrust.
