Piston compr. 10/25, Öhlins part number 04766-01. Rebuilding a piston means keeping the shim order, because the stack is the tuning.

  • Original Öhlins service part
  • Öhlins part number 04766-01

Function

This one measures 10 mm, 25 mm, and those figures are what separate it from the neighbouring numbers. The piston carries the shim stacks and meters the oil through its ports. Port area sets how much oil can pass before the shims begin to lift. Needle geometry sets the shape of the adjustable range, not just its size.

Why the Original

Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Order by part number. The dimensions below are the ones Öhlins publishes for it. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.

Getting the Number Right

Öhlins identifies this position by the number 04766-01 in the exploded view for the unit it belongs to. Öhlins states dimension a 10 mm, dimension b 25 mm for this number, and those figures are the deciding ones. The seat face has to be flat enough for the first shim to seal against it. Rebuilding a piston means keeping the shim order, because the stack is the tuning.

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.
