The Honda 15620-890-950 Oil Filler Cap is a genuine OEM replacement designed for the HT3810 lawn tractor. Sourced directly from Honda, this cap is an exact match for the original, ensuring a proper seal over the oil filler opening on your machine. If your existing cap is cracked, lost, or no longer sealing correctly, replacing it with part number 15620-890-950 is the straightforward fix to keep your tractor's lubrication system protected.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specification, so the cap fits and seals exactly as the factory part did from day one.
- Proper Oil System Seal — a correctly seating oil filler cap keeps contaminants out and prevents oil mist from escaping during operation, protecting the engine's lubrication system.
- Direct Replacement for the HT3810 — confirmed fitment for the HT3810 lawn tractor; verify your serial number against the fitment table to ensure this is the right cap for your unit.
The oil filler cap seals the opening used to add engine oil to the tractor's crankcase. It keeps dirt, debris, and moisture from entering the lubrication system while also preventing oil from being expelled during engine operation. A cap that is missing, cracked, or no longer seating securely allows contaminants into the oil supply and can lead to accelerated engine wear, making this a small part with an outsized impact on long-term engine health.
