This cog idler wheel is an aftermarket replacement for compatible snowblower drive systems. It supports and guides the belt where the original idler wheel has worn, cracked, or no longer turns properly. Built to match OEM This part is made to match the original cog idler wheel in fit and function for the intended snowblower applications. The cog profile, mounting fit, and overall finish are built for a straightforward replacement without changing the belt path or drive layout. Installation Installation is typically a bolt-on repair using basic hand tools. Remove belt tension, replace the worn idler wheel on the existing hardware, then confirm the belt is seated correctly and turns freely before putting the snowblower back to work. .product-description-v2 { font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif; color: #1d1d1d; line-height: 1.55; max-width: 720px; } .product-description-v2 > div { margin-bottom: 18px; } .product-description-v2 h3 { font-size: 16px; font-weight: 700; color: #1d1d1d; margin: 0 0 8px; } .product-description-v2 p { margin: 0; font-size: 15px; } @media (max-width: 768px) { .product-description-v2 { font-size: 15px; } }
