Titan 143-019 Retaining Ring
OEM Titan Mechanical Component
Titan 143-019 Retaining Ring is an OEM precision fastener that secures the connecting pin and other components within the fluid pump assembly on compatible PowrTwin, PowrLiner, PowrBeast, PowrTex, and ProMark sprayer models.
Compatibility Overview
Installs into a groove to create a positive shoulder that prevents axial movement of the connecting pin and other components. A worn, deformed, or missing retaining ring allows components to shift, causing vibration, misalignment, and potential pump failure. OEM replacement restores secure retention.

Titan 143-019 Retaining Ring for Fluid Pump Service
Titan 143-019 is an OEM retaining ring used to secure the connecting pin and other components within the fluid pump assembly of compatible PowrTwin, PowrLiner, PowrBeast, PowrTex, and ProMark sprayer models. Documented in the fluid section parts breakdown of official Titan service manuals for PowrLiner PL4955, PowrTwin PT6900 DI, and ProMark 98:2, this precision fastener installs into a groove to create a positive shoulder that prevents axial movement of the connecting pin and adjacent components. During fluid pump reassembly, Titan instructions specify sliding the retaining ring down over the connecting pin to secure the assembly. When the original retaining ring is worn, deformed, or missing, the connecting pin can shift, causing vibration, misalignment, and potential pump failure. This replacement restores secure component retention and reliable fluid pump operation.

| OEM Part Number | 143-019 Retaining Ring. |
| Common Problems Solved | Connecting pin axial movement, component misalignment, vibration, potential pump failure, and loss of assembly integrity. |
| Replacement Indicators | Visible deformation, cracks, or wear on the ring; inability to seat securely in the groove; missing ring from a previous service; or during any fluid pump rebuild. |
| Related Parts Commonly Serviced Together | Connecting pin (143-120), O-ring (145-031), packing set (138-153A), and other fluid pump components. Inspect all parts for wear during service. |
| Installation Notes | Slide the retaining ring down over the connecting pin to secure the assembly. Ensure the ring seats fully in its groove. Wear gloves to avoid pinching during installation. Verify secure retention before returning the unit to service. |
The 143-019 Retaining Ring is a critical retention component in the fluid pump assembly. Inspect it during any fluid pump service for deformation, cracks, or wear. Replace if any damage is found, as a compromised retaining ring allows the connecting pin to shift and causes vibration and misalignment. Verify model compatibility against your Titan service manual, as configurations vary across sprayer platforms.
