What It Is
This position is identified by its number rather than by a dimension. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away.
Why the Original
This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. 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. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.
Getting the Number Right
Part number 10432-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Where no measurement is given, the drawing position is what identifies the part. If it sticks open, the damper loses low-speed damping entirely. Rebuilding a piston means keeping the shim order, because the stack is the tuning.
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.
