Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position. A leaking damper is not a cosmetic problem: it is a damper that has stopped controlling the wheel. Dust seals keep grit off the running surface; once they are torn, the oil seal behind them has a short life.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Where a number has been superseded, Öhlins states the replacement — we pass that on. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 00438-49. Check inner diameter 63 mm, cross section 2.3 mm, material NBR 70 against what you have removed; a close size is not the same part. A seal that has taken a set no longer springs back and starts to weep. The groove does half the work: the ring only seals if the groove is clean and undamaged.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre.
