Function
Dimensionally this is 12.1 mm, 37 mm, 4 mm, which is how it is told apart from the rest of the range. Öhlins lists washers by thickness because it forms part of the internal stack height. These are the parts that are easy to lose on the bench and impossible to improvise afterwards. Öhlins gives every washer and spacer its own part number because its length or thickness is part of the internal geometry.
Genuine Service Part
Öhlins keeps service parts available for units long after they leave the current price list. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. Order by part number. The dimensions below are the ones Öhlins publishes for it. Service parts are ordered per piece unless stated otherwise.
Getting the Number Right
05921-01 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states dimension a 12.1 mm, dimension b 37 mm, dimension c 4 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 hold axial position under load; a sprung one lets the assembly walk.
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.
