DescriptionThe whole story▼
EC adjuster Ø34 assy SA Spare part, Öhlins part number 21704-98. Öhlins publishes the click count for each unit, and a rebuilt adjuster should return it.
Key Features
- Original Öhlins service part
- Öhlins part number 21704-98
Function
Öhlins publishes no separate dimension for this position, so the part number carries the identity. Öhlins publishes the click count for each unit, and a rebuilt adjuster should return it. Hydraulic preload adjusters are sealed units and are replaced rather than opened. Öhlins specifies a defined number of clicks per adjuster so a setting is a number, not an impression.
Original Öhlins Part
Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. We can supply the whole position from the drawing rather than the single piece if that is easier.
Getting the Number Right
Part number 21704-98 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. This position has no published dimension, so the part number is the only reliable identifier. A worn adjuster loses its clicks, and with them any chance of a methodical setup. Hydraulic preload adjusters are sealed units and are replaced rather than opened.
Fitting and Setup Service
A damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.
