340bulltaco Posted June 10, 2020 Report Share Posted June 10, 2020 (edited) Hi, I'm sorting out a 1967 500 Triumph twin engine in a B25 type frame. There isn't a lot of room for messing about with the primary chain tensioner at the back of the chaincase. I've seen passing references to fitting a C15/B40 slipper type tensioner in the primary case but can't find any real info on this. Is this a possibility or an old wifes tale??.

teamferret Posted June 10, 2020 Report Share Posted June 10, 2020 I did this a many years ago, and they don't fit straight on but i don't remember making a huge change. The slotted bracket which allows the tensioner to move up and down had to be moved but other than that it was straight forward. Bear in mind that my engine runs a smaller crank sprocket' Quote Link to comment Share on other sites More sharing options...

thai-ty Posted June 24, 2020 Report Share Posted June 24, 2020 Set the tension with the motor out of the frame, fit, and forget about it for at least one season, prolly more. Quote Link to comment Share on other sites More sharing options...
