The Powr 0290629A Belt Guard Assembly is a protective cover that encloses the drive belt system on compatible PowrLiner and PowrTwin sprayers. It shields the belt from dust, debris, and accidental contact, while also helping to maintain proper belt tension and alignment by securing the belt within the drive housing.
Over time, belt guards can become cracked, warped, or broken due to impact, vibration, or material fatigue. A missing or damaged guard exposes the belt to contaminants and creates a safety hazard. Replacing it restores a safe working environment and helps extend belt life by keeping the drive area clean.
