This bush fits into the camchain tensioner blade of the Laverda 1000 & 1200 models.

When a new camchain tensioner blade Laverda Part 31310213 is purchased it will not have this hardened steel bush included and it is expected that the existing bush will be re-used from the old blade. The ring is a press-fit onto the M6 threaded bush. Use a suitable punch or small slide hammer to drive the bush from the old blade. DO NOT use pliers as it will damage the ring.
