Function
Öhlins gives it as 16 mm, 3.5 mm, NBR 70; nothing about that is approximate. A seal that has taken a set no longer springs back and starts to weep. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. Nitrile, Viton and PTFE behave differently with temperature, and Öhlins picks per position.
Original Öhlins Part
Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. The exploded drawing for your unit names the number; if you do not have it, we do. Service parts are supplied per piece unless the description says otherwise.
How to Be Sure It Fits
If the unit is already open, compare the dimensions below with the part in your hand before ordering 00638-82. inner diameter 16 mm, cross section 3.5 mm, material NBR 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 uses seals with a spring-loaded lip so they follow the shaft as it wears.
Fitting and Setup Service
A damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.
