Description
Over time, the small circular rubber ring sitting around the clutch release camshaft spindle hardens from engine heat and pure age, losing its flexibility. When this happens, it allows a slow, annoying oil weep to develop, dripping down the back of your engine casing right onto your exhaust lines. Fitting this fresh replacement part restores a tight oil barrier and is essential for keeping your classic V-Twin clean and performing correctly on the road.

📜 Model Fitment Guide
Confirmed Engine Matches: Fits traditional air/oil-cooled V-Twin configurations:
- GV125 & GV250 Aquila: All classic cruiser air-cooled layouts built between 2001 and 2018.
- GT125, GT125R, GT250, GT250R Comet: All model years running either carburettor or electronic fuel injection up to 2020.
This part will NOT fit modern water-cooled GV125S EFI (2019 onwards) or GV300S Bobber generations. The newer engines use completely redesigned casing housings.
If you are dismantling your side engine link arm components to change this seal, take a quick minute to inspect your control lines. We highly advise cross-checking your Hyosung V-Twin Clutch Cable for wire strands breaking loose or heavy stiffness. Swapping a sticky cable completely transforms your gear selection!
🔧 Install Tips
- Clean the Metal Area: Ensure the engine metal bore surface is completely dry and free from old grit, grease, or dirt before inserting the fresh rubber ring.
- Lubricate the Lip: Smear a light drop of clean engine oil over the outer rubber wall of the seal. This simple trick allows it to glide smoothly into the engine block seat without bending or pinching out of shape.
- Apply Balanced Pressure: Find a workshop socket tool that aligns exactly with the firm outer rim of the seal ring. Gently tap it home until it sits completely flat and flush with the engine casing profile. Never push directly against the delicate internal seal edge.
If you are looking for advice on pulling out an old hardened rubber ring without scratching the alloy engine walls, head straight to the forums.
