PowrLiner part 0293938 is a 2nd Stage Gear Assembly used in the gearbox of PowrLiner 550 line stripers. This assembly is the second gear in a multi‑stage reduction system, further reducing speed and increasing torque from the first stage to drive the pump or drive system at the correct operating speed. Replacing a worn, chipped, or damaged second stage gear assembly restores smooth, quiet operation and reliable power transmission.

The PowrLiner 0293938 2nd Stage Gear Assembly is a critical component within the gearbox of PowrLiner 550 line stripers. It is the second gear in a multi‑stage reduction train, receiving rotational force from the first stage gear and transferring it at reduced speed and increased torque to subsequent stages or the final drive output.
This assembly typically includes the precision‑cut gear mounted on its shaft with bearings or bushings, ready for installation. Precision machining ensures smooth meshing with mating gears, minimizing noise and vibration while transmitting significant power. Over time, gear teeth can wear, chip, or break due to fatigue, lack of lubrication, or debris contamination. A damaged second stage gear leads to increased noise, rough operation, loss of power, and eventual gearbox failure. Replacing it with this complete assembly restores proper power transmission and extends the life of the machine.
| Speed reduction | Further reduces rotational speed from the first stage |
|---|---|
| Torque multiplication | Increases torque to drive the pump or drive wheels |
| Power transmission | Transfers mechanical energy through the gear train |
| Excessive noise | Grinding, whining, or clicking from gearbox |
|---|---|
| Visible tooth damage | Chipped, broken, or heavily worn gear teeth |
| Vibration | Unusual vibration during operation |
| Loss of power | Reduced output speed or stalling under load |
