what is better ? a cam chain or a cam belt?



id imagine cam belts are lighter and chains are stronger?

chain is safer and everything can be contained internally

the belts tend to be always on the outside

I don't think chains are lifed like belts either.

Hard question to answer, they all used to be chain, then started going belt, but some are reverting back, and some have stayed chain anyway, personally I'd rather have belt, as easier to do than a new chain when they rattle like fook.

Chains can do double the milage, some last 3 times a belts life,

Adv of belts

Quite running, low inertia, low power loss

Dis adv of belts

must be kept dry and oil free, service required, limited load capacity



Adv of chains

Strong, long life, low service requirement

Dis adv of chains

require complex tensioner as they stretch, noisy, inefficient

Hope that helps!

Last year I would have said chains, but this year both mine and my wifes car needed new engines due to timing chain failure. My new car has a belt
