Installation / Replacement Instructions

To install or replace the 15F656 pump cylinder, follow these general steps (refer to your machine’s service manual for exact torque and seal‑install specs):

Ensure system is depressurized and drained before disassembly.
Remove old cylinder/pump lower — preserve or replace all seals, packings, and related valves per manual.
Install new 15F656 cylinder — apply lubricant (per manufacturer guidelines) to sealing surfaces and packings; assemble with matching inlet/outlet housings and valves (e.g. 15F654) and tighten bolts to specified torque.
After reassembly, perform a controlled pressure test using clean solvent or recommended fluid to check for leaks, smooth fluid flow, and proper operation before full‑scale use.

Frequently Asked Questions

The 15F656 cylinder delivers 115 cc of fluid per pump stroke, appropriate for high‑volume or high‑viscosity fluid applications.

No — 15F656 is designed specifically for 115 cc lowers and requires matching outlet/inlet housings and fluid‑handling components (e.g. outlet housing 15F654) for correct fluid output and sealing. Mixing with incompatible housings may cause leaks, poor flow or damage.

Yes — using the original 15F656 ensures proper dimensions, sealing tolerances, and compatibility with Graco pump system components, which helps prevent leaks, pressure loss, or premature wear. Aftermarket cylinders may not meet the same specifications.
