What It Is
The published figures are 6 mm, 20 mm, 0.25 mm. Measure the old part against them before ordering. Two shims of the same thickness but different diameter give completely different curves. Revalving means changing the stack, which is why Öhlins sells shims individually. Öhlins holds thickness to hundredths of a millimetre because that is the resolution damping changes at.
Genuine Service Part
The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. The exploded drawing for your unit names the number; if you do not have it, we do. We can supply the whole position from the drawing rather than the single piece if that is easier.
Getting the Number Right
The reliable route is the exploded drawing: find the position, read the number, order it — 01425-20 in this case. inner diameter 6 mm, outer diameter 20 mm, thickness 0.25 mm is what distinguishes this number from its neighbours in the range. Two shims of the same thickness but different diameter give completely different damping. Öhlins holds thickness to hundredths of a millimetre because that is the resolution damping changes at.
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.
