Function

This one measures 1.5 mm, 50.8 mm, 30 mm, and those figures are what separate it from the neighbouring numbers. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics. Thread size identifies where it belongs on the unit. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal.

Genuine Service Part

Öhlins keeps service parts available for units long after they leave the current price list. The part number is the contract: it defines material, dimension and finish together. 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. We can supply the whole position from the drawing rather than the single piece if that is easier.

Getting the Number Right

If the unit is already open, compare the dimensions below with the part in your hand before ordering 21976-14. Check dimension a 1.5 mm, dimension b 50.8 mm, dimension c 30 mm against what you have removed; a close size is not the same part. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. A preload adjuster carries the full spring load and is built as a structural part.

Fitting and Setup Service

Ask us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.
