Fig. 15: Attaching new filter ring

Attach the new filter ring (81265) on the filter ring to be replaced so they overlap.

Fig. 16: Fitting new filter ring

Pull on the old filter ring until the new filter ring is completely wrapped around the filter
silencer.

Undo the connection between the new and the old filter ring.

Fasten the newly installed filter ring (81265), then fit circumferential part (9).
