Genuine Grasshopper - Block - Fuse Mounted 721 - 603132

Care & Installation

Engine top-end component (block-related part, rocker component). Follow the engine manufacturer's service manual for torque sequence and specification exactly — top-end fasteners are typically torqued in a specific pattern and value, and deviation can cause a leak or a more serious engine issue. Replace gaskets whenever the joint is opened, even if the old one looks reusable.
