duplex with a tensioner?
Turbo Mini Forums

Imo its down to the individual, tthere are people who do not fit them, who know from experience that they aren't necessary, and then there are people who have always fitted them, but many of those people have never actually tried without one and declared them a necessity.

yeah stick the bit in and give it a wobble

I have fitted them.

The way I look at it is that with a single chain, everytime you remove an old tensioner, it has two grooves in it wher the links have worn into it. the center between the two grooves is the bit thats doing all the work, as that is on the rollers. Fitting a tensioner on a duplex the groove will be in the middle, and you will then haave to areas either side of it on the rollers. Same thing.

or to look at it another way, I'll bet nobody can name a production car/bike engine that doesn't run a tensioner on a chain between crank and cam/cams? most run at least two with a tensioner one side and a guide on the other., most 16v stuff have a guide between the two cams as well. Those brummie engineers knew their onions don't forget.

If Carling made Mini engines
it would probably be like this one!

V8s from america?

I seriously doubt it!
