Honda 11300-ZL8-H00 Crankcase Cover Assembly

The Honda 11300-ZL8-H00 Crankcase Cover Assembly is a genuine OEM replacement designed for HS520 and HS720 single-stage snow blowers. As a direct OEM component sourced from Honda, this assembly delivers the exact fit and sealing integrity the original design requires. Confirm fitment using the serial number on your snow blower against the compatibility table, as Honda supersedes parts at production breaks. This Crankcase Cover Assembly is the correct choice when your original cover shows damage, warping, or oil seepage that can no longer be corrected by a gasket replacement alone.

Key Features

• Genuine OEM Sealing Integrity — manufactured by Honda to the exact tolerances required for proper crankcase sealing, preventing oil loss and protecting internal engine components in your snow blower
• Direct OEM Replacement — this assembly replaces the original cover without alteration, maintaining the correct mating surfaces and fastener pattern of the Honda engine in your HS520 or HS720
• Single-Stage Snow Blower Fitment — designed specifically for HS520 and HS720 single-stage snow blowers; verify your unit's serial number against the fitment table to confirm the correct supersession applies to your machine
• Protects Engine Longevity — a compromised crankcase cover allows oil to escape and contaminants to enter; replacing it with a proper OEM assembly restores the engine's sealed environment and keeps it running cleanly through demanding winter conditions

The crankcase cover seals one side of the engine's crankcase, enclosing the crankshaft, connecting rod, and associated internal components within a controlled, oil-lubricated environment. It works in tandem with the crankcase body and gasket to maintain oil pressure and keep dirt, moisture, and debris out of the engine's rotating assembly. When the cover cracks, warps, or develops a persistent leak, oil can escape rapidly during operation, leading to lubrication starvation and accelerated wear — or outright engine failure if the condition goes unaddressed.
