DescriptionThe whole story▼
Adjuster comp, Öhlins part number 21928-03. An adjuster that turns without resistance has lost its detent; the setting is then guesswork.
Key Features
- Original Öhlins service part
- Öhlins part number 21928-03
Where It Sits
Öhlins publishes no separate dimension for this position, so the part number carries the identity. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics. The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function.
Original Öhlins Part
Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Every part in this catalogue is one Öhlins fits itself during assembly and service. Order by part number — descriptions repeat across sizes, numbers do not. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.
Identifying the Right Part
Öhlins identifies this position by the number 21928-03 in the exploded view for the unit it belongs to. Öhlins does not publish a dimension here — go by the number and the exploded view. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.
Fitting and Setup Service
A damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.
