What It Is

This one measures 9.8 mm, 1.9 mm, NBR 70, and those figures are what separate it from the neighbouring numbers. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life. O-ring sizes are given as inner diameter and cross-section, and both have to match — a close size is not a match. A seal that has taken a set no longer springs back and starts to weep.

Genuine Service Part

Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. We can supply the whole position from the drawing rather than the single piece if that is easier. If you are between two sizes, send us the measurement and we will check it against the catalogue.

How to Be Sure It Fits

The reliable route is the exploded drawing: find the position, read the number, order it — 00339-03 in this case. inner diameter 9.8 mm, cross section 1.9 mm, material NBR 70 is what distinguishes this number from its neighbours in the range. Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.

Fitting and Setup Service

We are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.
