Function
The published figures are 41 mm, 2 mm, NBR 90. Measure the old part against them before ordering. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. A ring that has taken a set no longer springs back and starts to weep under pressure. Size is given as inner diameter and cross-section; a close size is not a match.
Genuine Service Part
An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Send us the model and serial number of your unit and we will confirm the position before you order. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.
Getting the Number Right
Order under 00638-76. Where several sizes share a description, only the number separates them. inner diameter 41 mm, cross section 2 mm, material NBR 90 is what distinguishes this number from its neighbours in the range. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Size is given as inner diameter and cross-section; a close size is not a match.
Fitting and Setup Service
Fitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.
