The Honda 15620-ZG4-910 is a genuine OEM Oil Filler Cap designed for an exceptionally wide range of Honda equipment, including GX110, GX120, GX140, GX160, GX240, GX270, GX340, and GX390 horizontal shaft engines, F401, F501, FR600, and FR800 tillers, HS521, HS522, HS621, HS622, HS624, HS80, HS828, and HS928 snow blowers, and WA20, WA30, WB20, WB30, WD20, WD30, WDP20, WDP30, WH15, WH20, WMP20, and WT30 water pumps. Sourced directly from Honda, this cap matches the original specification and drops into place with no adaptation required. Confirm your machine's serial number against the fitment table before ordering, as Honda has superseded components across serial breaks throughout this product range.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specification, ensuring the cap seats and seals exactly as the original did when the machine left the factory.
- Secure Oil Sealing — a correctly seating oil filler cap keeps the crankcase closed during operation, preventing oil contamination from external debris and maintaining the correct crankcase environment.
- Broad Cross-Equipment Fitment — a single part number covers Honda horizontal shaft engines, tillers, snow blowers, and multiple water pump families, including centrifugal and diaphragm models.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks across this wide fitment range; check your serial number against the compatibility table to confirm the correct cap for your unit.
The oil filler cap closes and seals the oil filler port on the engine crankcase, keeping the oil supply clean and contained during operation. A properly seating cap prevents dust, water, and debris from entering the oil supply, protecting internal engine components from contamination and wear. When the cap is cracked, missing, or no longer seals correctly, oil can be lost and contaminants can enter the crankcase, leading to accelerated wear and potential engine damage.
