Part number 448-241 is a Pulley used in PowrLiner 5000 line stripers. This pulley transfers power from the motor or engine to the drive system via a belt, providing speed reduction and torque multiplication. Replacing a worn, cracked, or damaged pulley restores proper belt alignment, reduces noise and vibration, and ensures reliable power transmission.

The 448-241 Pulley is a precision-machined wheel component used in the drive system of PowrLiner 5000 line stripers. It is designed to work with a belt to transmit rotational power from the engine or motor to the pump or drive wheels, providing the necessary speed reduction and torque multiplication for effective operation.
The pulley features a precisely machined groove that matches the belt profile, ensuring efficient power transfer and long belt life. Over time, pulleys can wear due to belt friction, debris contamination, or misalignment, resulting in groove wear, belt slippage, noise, and vibration. A worn or damaged pulley can also accelerate belt wear and lead to drive system failure. Replacing it restores proper belt tracking, smooth operation, and reliable power transmission.

When replacing the pulley, these components are often inspected or replaced at the same time to ensure complete drive system reliability.
Inspect for cracks, wear, or glazing; replace if worn.
Check the shaft and keyway for wear or damage that could affect pulley fit.
If the pulley mounts on a bearing, inspect for roughness or play.
