Titan 977-227 Pulley
OEM Titan Drive System Component
Titan 977-227 Pulley is an OEM replacement pulley used in the drive system of compatible PowrTwin and PowrLiner airless sprayers, transferring rotational power from the motor to the pump via a belt to maintain proper pump speed and pressure output.
Compatibility Overview
Precision-machined grooves match original equipment specifications for proper belt engagement and tracking. Balanced design reduces drive system vibration. A worn, corroded, or damaged pulley causes belt slippage, vibration, noise, and reduced pump efficiency. OEM replacement restores smooth power transmission and reliable operation.

Titan 977-227 Pulley for PowrTwin & PowrLiner Drive Systems
Titan 977-227 is an OEM replacement pulley designed for the drive system of compatible PowrTwin and PowrLiner airless sprayers. This precision-engineered component transfers rotational power from the motor or engine to the pump drive system via a belt, playing a critical role in maintaining proper pump speed and pressure output. The pulley is manufactured to exact specifications for groove profile, diameter, and balance, ensuring smooth operation and consistent power transmission. Any deviation from these specifications can result in belt wear, vibration, noise, and reduced pumping efficiency. In the demanding environment of professional painting, drive pulleys are subjected to continuous high-speed rotation, belt tension forces, and exposure to paint overspray and cleaning solvents. Over time, a pulley can develop wear on the belt contact surfaces, causing the belt to slip or track improperly. The pulley may also become damaged from belt failure, corrosion, or impact, leading to imbalance that causes vibration throughout the drive system. Common indicators of pulley wear include visible grooving or polishing on the belt contact surfaces, corrosion, cracks, or wobble when rotated. Replacing a worn pulley with the 977-227 restores proper belt alignment and tension, reducing vibration and ensuring the pump operates at the correct speed. It is documented as a component in the PowrLiner 4000 DC-Electric Convertokit. When installing a new pulley, ensure the shaft and keyway are clean and undamaged, torque the retaining hardware to manufacturer specifications, and verify belt alignment after installation. Always confirm fitment using the correct parts diagram for your exact model and revision, as drive configurations vary across sprayer platforms.
