Function
At 1.5 mm, 50.8 mm, 30 mm it fits one position only; the next size up carries a different number. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. The needle tip is the wear part: once rounded, the first few clicks stop doing anything. A preload adjuster carries the full spring load and is built as a structural part.
Genuine Service Part
Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. If you are between two sizes, send us the measurement and we will check it against the catalogue. We can check the number against the Öhlins exploded view before you order — just ask.
Identifying the Right Part
Öhlins identifies this position by the number 21932-14 in the exploded view for the unit it belongs to. The published dimensions are dimension a 1.5 mm, dimension b 50.8 mm, dimension c 30 mm — measure the old part against them if you are unsure. The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.
Fitting and Setup Service
We are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.
