What It Is
At 273.6 mm, 4.3 mm it fits one position only; the next size up carries a different number. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Hydraulic preload adjusters are sealed units and are replaced rather than opened. A bent adjuster shaft binds and the clicks become uneven.
Genuine Service Part
Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. If the unit is already apart, compare the published dimensions with the part in your hand. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.
Getting the Number Right
The reliable route is the exploded drawing: find the position, read the number, order it — 03566-23 in this case. Öhlins states dimension a 273.6 mm, dimension b 4.3 mm for this number, and those figures are the deciding ones. A preload adjuster carries the full spring load and is built as a structural part. The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable.
Fitting and Setup Service
Öhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.
