The Honda 12361-883-000 Tappet Room Cover is a genuine OEM replacement designed for a wide range of Honda engines and power equipment, including G200 horizontal shaft engines, E1500, ED1000, EG1500, EG2200, EM1600, EM1800, and EM2200 generators, F500 and FR500 tillers, HS50 two-stage snow blowers, and WA20, WA30, WB30, and WT20 water pumps. As a direct Honda OEM component, this cover is manufactured to the same specification as the original part it replaces. Because Honda supersedes parts across serial number breaks, always confirm your unit's serial number against the fitment table before ordering to ensure this is the correct cover for your machine.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this cover meets the exact dimensional and sealing requirements of the original, keeping the valve train properly enclosed and protected
- Broad Equipment Coverage — a single part number covering G200 engines, multiple generator and water pump models, HS50 snow blowers, and F500 and FR500 tillers, including E1500, EG2200, EM2200, WA30, WB30, and more
- Direct OEM Replacement — drops into place using the original mounting points with no modification required to hardware or gasket surfaces
- Serial Number Verification Recommended — Honda applies part supersessions at specific serial breaks across this range; check your serial number against the fitment table to confirm the correct fit for your unit
The Tappet Room Cover seals the valve train compartment on side-valve engines, keeping the tappets, cam lobes, and associated moving parts protected from dirt, debris, and oil splash while retaining lubrication where it belongs. A cracked, warped, or missing cover allows contamination into the valve train and can cause accelerated wear on the tappets and cam surfaces, leading to loss of compression and rough running. Keeping this cover in good condition is a straightforward but important part of long-term engine health across every machine in this fitment range.
