What It Is

Öhlins publishes 1.5 mm, 62.1 mm, 84 mm for 24638-11 — the dimensions are the identity of the part. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. An adjuster that turns without resistance has lost its detent; the setting is then guesswork.

Why the Original

Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins parts are unit-specific: a close dimension is not a substitute. We can check the number against the Öhlins exploded view before you order — just ask.

Identifying the Right Part

The reliable route is the exploded drawing: find the position, read the number, order it — 24638-11 in this case. The published dimensions are dimension a 1.5 mm, dimension b 62.1 mm, dimension c 84 mm — measure the old part against them if you are unsure. An adjuster that turns without resistance has lost its detent; the setting is then guesswork. 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.
