Caution

A distinction must be made between versions with and without release bolts (1).

In versions with release bolts the chain tensioner must be untightened using the release bolt after installation!

  Inspect

Press in the release pin with a hammer shaft until a click is heard.

It must be possible to push in release bolt up to stop with thumb and for it to slide back to its original position automatically – the release bolt can no longer be pushed in once the oil pressure has built up.
