AustrianVespaGuy Posted August 30, 2022 Share Posted August 30, 2022 Reassembling, got the timing cover on, popped the tensioner in (made sure the check ball valve was good first), and then went to bleed it, but seems. . . strange. Like the tensioner shoe is too far towards the head, and it doesn't quite want to engage with the tension piston. It will with a little lateral pressure, but then the piston doesn't want to move freely. Hopefully the video helps make things clear. Keep pumping, or is something wrong here?

Solution tzei Posted August 30, 2022 Solution Share Posted August 30, 2022 Pliers & twist it a bit? Quote Link to comment Share on other sites More sharing options...
bergie33 Posted August 30, 2022 Share Posted August 30, 2022 Do you have an aftermarket tensioner arm? Given scarce availability, there may be many brands that are manufactured to exacting specs. I second tzei's suggestion to bend the contact arm of the tensioner to fit the piston. Quote Link to comment Share on other sites More sharing options...
AustrianVespaGuy Posted August 30, 2022 Author Share Posted August 30, 2022 Not aftermarket, just re-using my old one from several years ago as not that many mile on it and still in great shape, but yeah I might need to resort to the old twisty-with-a-tool. How malleable is that stuff? Cast aluminum is neither particularly ductile, though nor dangerously brittle, right? Quote Link to comment Share on other sites More sharing options...

John76 Posted August 31, 2022 Share Posted August 31, 2022 Did you loosen the screw plug slightly before exercising the piston? You should get oil squirting out to bleed the air pocket. Quote Link to comment Share on other sites More sharing options...
