Titan 107-029 Displacement Rod
OEM Titan Fluid Section Components
Titan 107-029 Displacement Rod and 107-055 Outlet Valve Housing are OEM fluid section components that work together to drive the piston and control material flow in compatible PowrBeast, PowrLiner, and PowrTwin sprayer models.
Compatibility Overview
The displacement rod transmits force from the hydraulic piston to the fluid piston, while the outlet valve housing seats the outlet valve and lower packings. Worn rods cause scoring and seal damage; worn housings cause poor seating and pressure loss. OEM replacement restores proper alignment and sealing.

Titan 107-029 Displacement Rod and 107-055 Outlet Valve Housing
Titan 107-029 is the OEM displacement rod that forms the core of the fluid pump, carrying the piston assembly and connecting to the hydraulic piston rod via the connecting pin and retaining ring. Titan 107-055 is the OEM outlet valve housing that threads onto the bottom of the displacement rod, seating the outlet valve ball, seat, and cage while supporting the lower packings. Together these components are documented in the official PowrLiner PL4955/6955/8955 fluid section parts breakdown. During pump reassembly, Titan instructions specify threading the outlet valve housing onto the displacement rod with blue Loctite and torquing to 50 ft.-lbs. (68 Nm). A worn or scored displacement rod damages packings and causes fluid bypass; a damaged outlet valve housing prevents proper valve seating and causes pressure loss. This pairing restores proper alignment, sealing, and reliable pump performance.

|---|---|
| Product Overview | OEM Titan displacement rod (107-029) and outlet valve housing (107-055) for the fluid section of compatible PowrBeast, PowrLiner, and PowrTwin sprayers. |
| 107-029 Function | Displacement rod carries the piston assembly, connects to the hydraulic piston rod via the connecting pin, and reciprocates through the upper and lower packings to displace fluid. |
| 107-055 Function | Outlet valve housing threads onto the displacement rod, seats the outlet valve ball/seat/cage, and provides the mounting surface for the lower packing set and spring. |
| System Location | Fluid pump section. Listed in the official PowrLiner PL4955/6955/8955 fluid section parts breakdown. |
| Documented Compatible Models | PowrBeast 4700T/4700; PowrLiner 4000, 4900, 4900XLT, 4950, 4955, 5000, 6900XLT, 6955, 8955; PowrTwin 3500, 3500 50th Anniversary, 3500-DC, 4500, 4900, 4900GH, 4900XLT. Verify your exact model and revision against the service manual before ordering. |
| OEM Part Numbers | 107-029 Displacement Rod; 107-055 Outlet Valve Housing (alternate 0107-055). |
| Common Problems Solved | Scored or worn rod damaging packings, fluid bypass past piston, outlet valve leakage, poor valve seating, pressure loss, and erratic pump output. |
| Replacement Indicators | Visible scoring, wear, or corrosion on rod surface; damaged threads on rod or housing; outlet valve leaks or poor seating; pressure loss not resolved by packing replacement. |
| Related Parts Commonly Serviced Together | Packing sets, upper/lower packing springs, outlet valve ball/seat/cage, seal washer, connecting pin (107-003), and retaining ring (143-019). |
| Installation Notes | Coat outlet valve housing threads with blue Loctite #242, thread onto displacement rod, and torque to 50 ft.-lbs. (68 Nm). Soak leather packings in oil before assembly. Align displacement rod holes with hydraulic piston rod and secure with connecting pin and retaining ring. |
The 107-029 Displacement Rod and 107-055 Outlet Valve Housing are critical to fluid section performance. Inspect the rod for scoring and the housing for thread damage or valve seat wear during any pump rebuild. Replace if damaged, as worn components compromise sealing and cause pressure loss. Verify model compatibility against your Titan service manual, as fluid section configurations vary across sprayer platforms.
