Titan 705-104 Retainer for Upper Packing Retention
Titan 705-104 is a genuine OEM retainer nut engineered to secure the upper packing assembly within the fluid section of compatible Titan airless sprayers. Official Titan manuals for the 740IX identify it as the "Retainer nut", and the Advantage 600 manual lists it as item #1, "Retainer nut". Bedford Precision references confirm its specific function as the "Packing Retainer Nut, upper" for the 740i Epic and PowrLiner 2850. This retainer threads into the pump block and applies the correct compression to the upper packings, ensuring they seal properly against the piston rod. A worn, stripped, or missing retainer allows the packings to shift or lose compression, leading to fluid leaks, pressure loss, and accelerated wear on the piston rod.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine Titan OEM retainer nut for the upper packing assembly in compatible airless sprayers. Threads into the pump block to secure and compress the upper packings. |
| Function | Holds the upper packing assembly in position within the pump block. Applies proper compression to the packings for a leak-free seal against the piston rod. Torque specification: 300-360 in. lbs. |
| Compatible Titan Models | 740 i, 740 IX; Advantage 600, GPX 85; PowrLiner 2850 GB_D_F, 1800M, 2800M; SprayTech GPX 85. |
| OEM Part Number | 705-104 Retainer Nut. |
| Replacement Indicators | Cracked or stripped threads on the retainer; corrosion or damage to the nut; upper packing area leaking fluid; loss of pump pressure; retainer loose or unable to hold packing compression. |
| Related Parts Commonly Serviced Together | Upper packing assembly (800-454), upper guide (705-105), piston rod assembly, packing grease. |
| Common Problems Solved | Restores proper packing compression, eliminates fluid leaks at the upper packing area, maintains pump pressure, and prevents premature packing failure. |
| Why Genuine OEM | Exact thread dimensions and material specifications ensure proper fit and reliable retention. A low quality or incorrect retainer may strip, fail to hold compression, or leak under pressure. |
When servicing the upper packing assembly, inspect the 705-104 retainer for stripped threads, cracks, or corrosion. Replace if damaged. During reassembly, ensure the retainer is correctly seated and tightened to the specified torque (300-360 in. lbs) to achieve proper packing compression. Always relieve system pressure and disconnect power before servicing the fluid section.
