DescriptionThe whole story▼

Shims 8/18/0.20, Öhlins part number 00186-18. Changing one shim in a stack alters the damping curve measurably; that is why Öhlins sells them individually rather than only as sets.

Function

Öhlins publishes 8 mm, 18 mm, 0.20 mm for 00186-18 — the dimensions are the identity of the part. Revalving means changing the stack, which is why Öhlins sells shims individually. A coned or marked shim is finished — it no longer seals against its neighbour. Suspension technicians keep these in stock by size because a revalve means changing several at once.

Why the Original

Öhlins keeps service parts available for units long after they leave the current price list. Every part in this catalogue is one Öhlins fits itself during assembly and service. Send us the model and serial number of your unit and we will confirm the position before you order. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.

Getting the Number Right

The reliable route is the exploded drawing: find the position, read the number, order it — 00186-18 in this case. Öhlins states inner diameter 8 mm, outer diameter 18 mm, thickness 0.20 mm for this number, and those figures are the deciding ones. Revalving means changing the stack, not the piston — that is why shims are sold singly. Two shims of the same thickness but different diameter give completely different curves.

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.
