Oil Filter Cover O-Rings (Cap Rubber Seals) – Hyosung GV650 GT650 GT650R
Cheap insurance for your 650cc V-Twin. These two O-rings are critical for sealing your oil filter cap and maintaining proper internal oil pressure. Replacing them during your routine servicing avoids messy drops on the casing and keeps your lubrication path sealed tight.

Description
Oil weeping from your filter cover usually means the large outer O-ring has become brittle and cracked. The small inner O-ring (which is often forgotten!) is vital for ensuring oil is filtered correctly and maintaining pressure to the engine. Whether you’re doing a quick oil change or a full service, replacing these two high-quality rubber seals is cheap, easy insurance to avoid long-term engine problems.

📜 Confirmed Fitment Guide
Confirmed V-Twin Matches: Fits 650cc and 700cc model configurations running from 2005 to 2020:
- GT650 / GT650R / GT650S: Fits all carburettor and fuel-injected generations.
- GV650 Aquila: Matches naked, classic, and EFI custom builds.
- ST7 Cruiser (GV700i): Perfect companion fitment for the 700cc touring setup.
- OEM Reference: Swaps out factory part numbers 09280H69001 and 09280H16001.
❌ WILL NOT FIT THESE MOTORCYCLES:
- Smaller Engine Platforms: Does NOT fit the 125cc, 250cc, or liquid-cooled 300cc engine casings, which utilize entirely separate sizing patterns.
🔧 Install Tips
- Lubricate Before Fitting: Always coat both rubber rings with a light film of fresh engine oil before sliding them into their slots. This stops the rubber from pinching, twisting, or tearing when you push the cap back on.
- Clean the Seat: Wipe down the internal cap grooves and engine block casing lines with a lint-free rag to clear away old grit or hard crust that blocks a flush fit.
- Don’t Overtighten: Secure the cover bolts evenly until snug. Overtightening will crush the rubber shapes flat or strip out the soft metal casing threads.
