Titan 106-005 Upper Packing Spring
OEM Titan Pump Component
Titan 106-005 Upper Packing Spring is an OEM stainless steel spring that maintains proper tension on the upper packings inside the displacement pump of compatible PowrBeast, PowrLiner, and PowrTwin sprayer models, ensuring a reliable seal and preventing fluid bypass.
Compatibility Overview
Applies consistent upward pressure against the upper packings, keeping them expanded against the piston and cylinder wall. A worn, collapsed, or broken spring causes pressure loss, erratic spray performance, and fluid leakage. OEM replacement restores proper seal compression and reliable pump output.

Titan 106-005 Upper Packing Spring for Fluid Pump Service
Titan 106-005 is an OEM stainless steel upper packing spring used in the fluid pump of compatible PowrBeast, PowrLiner, and PowrTwin sprayer models. Documented as item 5 "Packing spring, SS" in the official PowrLiner 4000 manual and as the upper packing spring in the PowrTex 6900SF/12000SV service manual, this precision spring applies consistent upward pressure against the upper packings inside the pump cylinder. This tension keeps the packings properly expanded against the piston and cylinder wall, creating a tight seal that prevents fluid from bypassing the piston. During pump reassembly, Titan instructions specify placing the upper packing spring into the motor/pump block with the small tapered end facing up toward the motor/pump block. Over time, the spring can lose tension, become distorted, or break due to fatigue, chemical exposure, or debris. A failed spring leads to pressure loss, erratic spray performance, pump stall, or fluid leaking into the lower pump section. This replacement restores proper seal compression and reliable pump output.

| OEM Part Number | 106-005 Upper Packing Spring (Packing spring, SS). |
| Common Problems Solved | Loss of pressure, erratic spray performance, fluid bypass past packings, fluid leaking into lower pump section, and pump stall. |
| Replacement Indicators | Visible rust, weakness, deformation, or breakage; pump cannot maintain rated output pressure; fluid seeping past packings; or during any packing replacement. |
| Related Parts Commonly Serviced Together | Upper packing set (4), Teflon O-ring (3), displacement rod (7), and lower packings. Always replace the spring when replacing packings if it shows signs of wear. |
| Installation Notes | Place the upper packing spring into the motor/pump block with the small tapered end facing up toward the motor/pump block. Soak packings in oil before installation. Inspect the spring for damage before installation and replace if worn. |
The 106-005 Upper Packing Spring is a critical component in the fluid pump assembly. Inspect it during any pump service for rust, weakness, deformation, or breakage. Replace if any damage is found, and always replace the spring when replacing packings if it shows signs of wear. Verify model compatibility against your Titan service manual, as pump configurations vary across sprayer platforms.
