Hydr preload integrated right assy 2:1, Öhlins part number 21686-02. Compression and rebound adjusters are not interchangeable even when they look similar.
Key Features
- Öhlins part number 21686-02
- Original Öhlins service part
What It Is
Öhlins publishes no separate dimension for this position, so the part number carries the identity. An adjuster that turns without resistance has lost its detent; the setting is then guesswork. Detent balls and springs are separate parts because they wear before the housing does. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics.
Genuine Service Part
Rebuilding to specification only works if the parts are to specification — that starts here. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. If you are between two sizes, send us the measurement and we will check it against the catalogue.
Getting the Number Right
21686-02 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins does not publish a dimension here — go by the number and the exploded view. Compression and rebound adjusters are not interchangeable even when they look similar. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.
Fitting and Setup Service
Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
