Cambelt tensioning tools - Carl 2
I notice that Sykes Pickavant sell a universal cambelt tensioning tool for just over £150. I always change my own cambelts ( simple basic cars) using the twist method . Although I have never had a problem I would happily check the tension with one of these gauges or any similar tools if any one could endorse this product or any other . I would be grateful of any information as I have only seen a picture of this tool and therefore have no experience of its effectiveness.

Carry on `twisting Carl and keep ypur £150 in your pocket.If the tension is so critical ,why is it never scheduled to be re checked for tension before the next change ?

I think the reason that belts are not checked for tension is that the tensile members (kevlar, polyester etc) have virtually zero EAB (elongation at break). So, its not like an alternator belt that stretches. It's one reason why visual inspection of a belt reveals very little about its internal condition. Other than, say, being oil soaked is not good for it, you can't tell a lot from its appearance. Hence the advice to change it frequently, and early!

The recommendation is now not to twist the belt. There are even instuctions regarding the tightest radius they can be bent to during storage! Twisting and bending is supposed to damage the fibres laminated inside the belt.
