DescriptionThe whole story▼
Piston reb., Öhlins part number 04765-03. Port area and shim seat geometry decide the damping curve before any adjuster is touched.
Key Features
- Öhlins part number 04765-03
- Original Öhlins service part
Function
This position is identified by its number rather than by a dimension. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. Needle geometry sets the shape of the adjustable range, not just its size.
Original Öhlins Part
Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. We can supply the whole position from the drawing rather than the single piece if that is easier. We can check the number against the Öhlins exploded view before you order — just ask.
Getting the Number Right
If the unit is already open, compare the dimensions below with the part in your hand before ordering 04765-03. Where no measurement is given, the drawing position is what identifies the part. Rebuilding a piston means keeping the shim order, because the stack is the tuning. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.
Fitting and Setup Service
Öhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.
