Stop washer 21/44/10 clear, Öhlins part number 01284-03. Thread size and length identify the fastener; substituting a hardware-store equivalent is not sensible in a pressurised damper.

Where It Sits

Dimensionally this is 21 mm, 44 mm, 10 mm, which is how it is told apart from the rest of the range. Fasteners in a damper see pressure, heat and vibration at once, which is why the grade matters. Small parts are what hold a rebuild together — the wrong circlip or washer is enough to fail the job. Öhlins lists washers by thickness because it forms part of the internal stack height.

Genuine Service Part

The part number is the contract: it defines material, dimension and finish together. The part is identical to what Öhlins fits in production — same supplier, same specification. If you are between two sizes, send us the measurement and we will check it against the catalogue. Service parts are supplied per piece unless the description says otherwise.

Getting the Number Right

The reliable route is the exploded drawing: find the position, read the number, order it — 01284-03 in this case. Öhlins states dimension a 21 mm, dimension b 44 mm, dimension c 10 mm for this number, and those figures are the deciding ones. Spacers set the internal geometry of the unit, which means their length is a specification and not a filler. Circlips are single-use in practice: once sprung, they no longer hold their groove reliably.

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.
