DescriptionThe whole story▼

Cylinder head TTX36, Öhlins part number 21897-01. Öhlins hones its tubes to a defined surface finish rather than simply to a diameter.

Key Features

  • Original Öhlins service part
  • Öhlins part number 21897-01

Function

Öhlins publishes no separate dimension for this position, so the part number carries the identity. Öhlins machines the head so the bushing bore is concentric with the seal — otherwise the shaft wears one side. The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair. Head and tube are matched by thread and diameter; neither is interchangeable across units.

Why the Original

Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. Send us the model and serial number of your unit and we will confirm the position before you order. If the unit is already apart, compare the published dimensions with the part in your hand.

Identifying the Right Part

If the unit is already open, compare the dimensions below with the part in your hand before ordering 21897-01. Where no measurement is given, the drawing position is what identifies the part. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Twin-tube dampers use two concentric tubes, and both are listed separately.

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.
