Where It Sits
00438-84 is the 82 mm, 5 mm, NBR 70 version — Öhlins lists each size separately. Seal heads combine the oil seal, the dust seal and the bushing in one assembly. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. Öhlins recommends replacing seals whenever the unit is opened, not only when it leaks.
Genuine Service Part
The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. The part is identical to what Öhlins fits in production — same supplier, same specification. The exploded drawing for your unit names the number; if you do not have it, we do. Tell us the damper's model designation and year and we will match the number for you.
Getting the Number Right
If the unit is already open, compare the dimensions below with the part in your hand before ordering 00438-84. Check inner diameter 82 mm, cross section 5 mm, material NBR 70 against what you have removed; a close size is not the same part. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost. The groove does half the work: the ring only seals if the groove is clean and undamaged.
Fitting and Setup Service
Ask us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.
