Where It Sits
Öhlins publishes 56.82 mm, 2.62 mm, FKM 70 for 00338-99 — the dimensions are the identity of the part. Static seals and dynamic seals are not interchangeable even in the same size. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. Seals are the part of a damper that decides whether it holds its gas charge and its oil, and they are the usual reason a unit ends up on the bench.
Genuine Service Part
The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. The exploded drawing for your unit names the number; if you do not have it, we do.
How to Be Sure It Fits
The reliable route is the exploded drawing: find the position, read the number, order it — 00338-99 in this case. inner diameter 56.82 mm, cross section 2.62 mm, material FKM 70 is what distinguishes this number from its neighbours in the range. A seal that has taken a set no longer springs back and starts to weep. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.
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.
