itan part 235-118A is a Motor Pump Assembly for heavy-duty, high-output professional line striping machines. This assembly combines the hydraulic motor and the high-pressure fluid pump into a single, pre-assembled unit. It is designed as a direct, drop-in replacement for the core power system in a wide range of Titan Powerliner and PowrTwin series models, providing up to 3300 PSI of pressure for striping applications.

The Titan 235-118A is a genuine OEM Motor Pump Assembly that forms the core power and pressure generation system for a broad range of Titan's heavy-duty line striping machines. This complete assembly replaces the combined hydraulic motor and high-pressure pump, delivering the robust performance required for professional-grade striping on large-scale projects like airport runways, parking lots, and athletic fields.
This assembly is a primary service component for maintaining critical system performance. A worn or failed motor pump assembly will cause a complete loss of pressure, leading to an inability to spray or maintain consistent line quality. Replacing it with the genuine Titan 235-118A assembly restores the striper's maximum output and ensures reliable operation with a pressure range from 400 to 3300 PSI.
| Power Conversion | Converts the engine's mechanical power into hydraulic pressure, which drives the high-pressure paint pump. |
|---|---|
| Pressure Generation | The pump section creates the high operating pressure (up to 3300 PSI) needed to atomize and spray thick traffic paints. |
| System Heart | Serves as the central mechanical component linking the power source to the spray output system. |
| Complete Pressure Loss | The machine runs but produces no spray pressure, even after checking valves and hoses. |
|---|---|
| Severe Internal Wear | Irreparable damage to the pump's internal components (e.g., scored pistons, worn valves) not fixable with a seal kit. |
| Motor Failure | The hydraulic motor is seized, has internal damage, or has catastrophic bearing failure. |
| Major Overhaul | As a complete replacement unit for a high-hour machine or to reduce downtime on a critical piece of equipment. |
The Titan 235-118A is the standard motor pump assembly for the "PT6900 XLT" family of heavy-duty line stripers. It is compatible with the following series and models:
| Compatible Series | Specific Compatible Models |
|---|---|
| PowrLiner / PowrLiner Series | PowrLiner 4955, PowrLiner 6955, PowrLiner 8955, PowrLiner 4950, PowrLiner 6950 (Single or Dual Gun), PowrLiner 6950_1 |
| PowrTwin Series | PowrTwin 4900, PowrTwin 6900, PowrTwin 8900, PowrTwin 12000 Plus |
Note on PowrLiner 6950: The 6950 is a high-output, professional machine designed for large-scale pavement striping and has been succeeded by the 6955 model. This motor pump assembly is a critical part for both.
When replacing a major assembly like the motor pump, inspect these related system components to ensure the longevity of the new unit.
For minor leaks or maintenance, a seal kit (e.g., Repair Kit - Pump: 144-050) may be sufficient.
Ensure the hydraulic system is clean and filled with the correct fluid. Contaminated fluid can damage a new motor pump.
Check engine couplers, mounting bolts, and drive linkages for wear when installing the new assembly.
A clean, 50-mesh paint inlet filter (standard on these models) protects the pump from abrasive debris.
