Product Description
When a generator’s mechanical components start to wear, movement can feel sloppy, and operations that used to be smooth can become unpredictable. The Generac 178851 Inner/Outer Idler Arm Retrofit Kit replaces worn pivot points in the idler arm system, so belt tension and engine movement stay steady. Loose or worn idler arms can cause belts to slip, reduce performance, and increase the risk of breakdowns just when you need consistent power.
This retrofit kit includes both the inner and outer idler arm components that help guide and maintain the right tension on the drive belt. Keeping the belt properly tensioned is important because it connects rotating parts that help your generator start and run efficiently. Worn idler arms can allow the belt to wobble or shift, leading to uneven operation or extra wear on related parts.
Generator Magic only sells OEM Generac parts, ensuring your generator runs properly and avoids the fit issues that can come with aftermarket replacements. The Generac 178851 Inner/Outer Idler Arm Retrofit Kit maintains correct belt tension and movement, so your engine runs as expected. Choose this idler arm retrofit kit to tighten up belt action and help your generator maintain dependable mechanical motion.
