Titan 704-552A Piston Assembly for Fluid Section Rebuilds
Titan 704-552A is a replacement piston assembly specified for designated Titan fluid sections. It combines the piston rod with the associated outlet-valve arrangement, supporting the pump's reciprocating action and check-valve operation.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan piston assembly for designated fluid sections. Combines the piston rod with specified outlet-valve components to support reciprocating action and check-valve operation. |
| Function | Moves back and forth within the fluid section, working with packings and the inlet system to move material through the pumping chamber. The outlet ball and seat form the check-valve arrangement, with the cage guiding the ball and the washer and retainer completing the assembly. |
| Documented Contents | Piston rod 704-551A, upper cage 704-610, crush washer 704-612, outlet ball 50164, seat 704-558, and retainer 13481. Confirm currently supplied package contents before ordering additional parts. |
| Industrial Applications | Professional sprayer repair, fluid section rebuilds, pump maintenance, and rental fleet servicing. |
| Compatible Titan Machines | Documented in Titan service guide: Impact 410, 440, 540, 640. Manufacturer manuals list selected Advantage 400, Advantage 500, and Helix LP configurations. Third-party listings also cross-reference RentSpray 450, 650; PowrLiner 3100; and Epic 447HPX, 660HPX, 660XC, 690HPG. Always confirm 704-552A in the exact installed fluid-section documentation. |
| Impact X Compatibility | Impact X models require a separate compatibility check. Titan's service guide specifies 2420580A for Impact X 410, 440, and 540I piston assemblies. Do not assume 704-552A fits Impact X models. |
| OEM Part Number | 704-552A Piston Assembly. Replaces Titan 730-506 and 509588 in some references. |
| Related Components | Upper and lower packings (separately identified); piston guide and bushings; inlet valve components (ball, seat, cage, seals); pump housing and drive connection; repacking kit 0552951 for Advantage 400 configurations. These are separately identified service components and are not included with the piston assembly. |
| Common Problems Solved | Rod wear or scoring; multiple outlet-valve faults; mechanical or connection damage; repeated packing problems; pressure loss; uneven spray patterns. |
| Target Users / Markets | Painting contractors, equipment maintenance technicians, rental fleet operators, and repair shops servicing compatible Titan airless sprayers. |
| OEM & Brand Information | Genuine Titan OEM component designed for correct mechanical fitment in compatible sprayer fluid sections. |
| Commercial Benefits | Restores proper pump pressure generation, supports consistent fluid movement, improves system efficiency, and extends fluid section service life. |
Complete the manufacturer pressure-relief procedure and isolate all power sources before servicing. Verify that the installed fluid section documentation specifies 704-552A. Follow the prescribed removal sequence and protect the rod's working surfaces from tool damage. Inspect packings, upper guide, bushings, inlet valve, pump housing, and drive connection before installation. Reassemble according to the manual, following exact requirements for packing orientation, lubrication, assembly placement, and connection tightening. Never use your hand to locate a pressurized leak.
