What It Is

This one measures 173.3 mm, 4.3 mm, and those figures are what separate it from the neighbouring numbers. Click adjusters work through a needle in a seat; the detent spring gives the clicks their feel. A preload adjuster carries the full spring load and is built as a structural part. The adjuster shaft runs inside the damper shaft and carries the adjustment to the piston.

Why the Original

Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins parts are unit-specific: a close dimension is not a substitute. If the unit is already apart, compare the published dimensions with the part in your hand.

How to Be Sure It Fits

The reliable route is the exploded drawing: find the position, read the number, order it — 00566-27 in this case. dimension a 173.3 mm, dimension b 4.3 mm is what distinguishes this number from its neighbours in the range. The adjuster shaft runs inside the damper shaft and carries the adjustment to the piston. A preload adjuster carries the full spring load and is built as a structural part.
