Find the Correct EPX2155 Gear Box Replacement Parts
The EPX2155 gear box forms part of the mechanical drive system between the electric motor and the piston-pump mechanism. Its job is to transfer motor output through the drive system so the fluid section can cycle and develop the pressure required for airless spraying.
Gear box service requires accurate parts identification. Locate the component on the EPX2155 gear box exploded diagram, note its callout and match that reference to the documented OEM part number. If diagnosis indicates that the problem originates in the motor or fluid section, continue to the appropriate dedicated EPX2155 assembly diagram.

Confirm the OEM part number and EPX2155 application before purchasing the replacement component.
EPX2155 Mechanical Drive Components to Inspect
Use the factory gear box breakdown to identify the documented drive components installed in your EPX2155 and their relationship to the motor and pumping mechanism.
Inspect documented gears for abnormal wear, damaged teeth or other conditions that can interfere with mechanical power transfer.
Identify the applicable shafts and related components responsible for transmitting movement through the drive system.
Inspect documented bearing and support components when diagnosing abnormal movement, noise or mechanical resistance.
Check applicable housing components for physical damage and verify mounting points and interfaces with connected assemblies.
Locate documented screws, washers, retainers and other hardware used to secure gear box and drive components.
Inspect the mechanical interface between the motor and gear box when the motor operates but drive movement is abnormal.
Check the connection between the gear box and pumping mechanism when drive motion is not being transferred correctly to the fluid section.
Inspect documented covers, guards and related components for proper installation and physical condition.
Symptoms That Can Point to the EPX2155 Gear Box
| Symptom | Inspect First | Also Check | Before Ordering |
|---|---|---|---|
| Abnormal Gear / Drive Noise | Gear box and drive components | Motor and mounting points | Identify the source of the noise |
| Motor Runs but Pump Does Not Cycle | Motor-to-drive and gear box interfaces | Fluid section / pump drive | Confirm where motion stops |
| Binding or Irregular Movement | Gears, bearings and shafts | Pump mechanism | Inspect for mechanical damage |
| Excessive Vibration | Mounting hardware and drive interfaces | Motor and main assembly | Check for looseness or wear |
| Pump Cycles Incorrectly | Mechanical drive system | Fluid section and valves | Separate drive faults from fluid faults |
| Low Spray Pressure | Fluid section and suction system | Drive operation | Do not assume gear box failure |
Diagnose the Drive System Before Replacing Gear Box Parts
Mechanical symptoms can originate in the motor, gear box, pump drive or fluid section. Determine where power transmission becomes abnormal before selecting individual replacement parts.
Inspect the connection from the motor through the gear box to the pumping mechanism to determine where drive movement is interrupted.
Stop operation and inspect documented gears, bearings, shafts and connected components for wear or physical damage.
Investigate the gear box and pumping mechanism for binding or damaged components before continued operation.
Check mounting hardware, motor alignment and mechanical drive interfaces for looseness, wear or damage.
Confirm that the drive is cycling correctly, but also inspect the suction system, fluid section, valves, hose, gun and spray tip.
Look beyond the visibly worn component and inspect connected drive parts for alignment, damage or conditions contributing to repeated wear.

Verify EPX2155 Gear Box Parts by OEM Part Number
Do not assume that a gear, bearing, shaft, housing or other drive component from an EPX2255, EPX2355, EPX2455, EPX2555 or another SprayTech sprayer fits the EPX2155. Similar appearance does not establish interchangeability. Use the EPX2155 gear box diagram and verify the documented OEM part number before ordering.
Help Protect the EPX2155 Gear Box & Drive System
Do not ignore new grinding, knocking or other abnormal mechanical sounds from the motor and gear box area.
Check accessible fasteners and mounting points for looseness or physical damage during routine maintenance.
Changes in pump cycling, vibration or mechanical movement can indicate that the drive system requires inspection.
Problems in the motor or fluid section can place abnormal demands on the drive system, so diagnose the complete mechanical path.
EPX2155 Gear Box Service Safety
Disconnect electrical power, shut the sprayer down and follow the applicable pressure-relief procedure before servicing the gear box or connected assemblies. Never work on moving drive components while the sprayer is energized. Airless equipment also contains hazardous fluid pressure, so relieve pressure before opening any fluid-system connection.

How do I identify the correct EPX2155 gear box part?
Confirm the EPX2155 model, locate the component on the gear box exploded diagram, note its callout and match that reference to the documented OEM part number.
What should I check if the EPX2155 motor runs but the pump does not cycle?
Inspect the mechanical path from the motor through the gear box to the pump drive. Determine where movement is interrupted before replacing individual drive components.
What can cause unusual noise from the EPX2155 gear box area?
Abnormal mechanical noise requires inspection of the documented gears, bearings, shafts, mounting points and connected motor and pump-drive components. Stop operation if mechanical damage is suspected.
Can EPX2255 gear box parts be used on an EPX2155?
Do not assume compatibility between Advantage models. A component should be used only when its documented OEM part number and application confirm that it fits the EPX2155.
Is low spray pressure always a gear box problem?
No. Low pressure can involve the suction system, fluid section, inlet or outlet valves, hose, gun or spray tip. Confirm correct mechanical drive operation and diagnose the complete fluid system.
Should I continue using the EPX2155 if the gear box makes a grinding noise?
Stop operation if abnormal grinding or other signs of mechanical damage are present. Continued use may worsen damage to connected drive components. Inspect the system before returning the sprayer to service.
