Timing Belt Tension - F9Q DCI Diesel Engine


This is an idea that entered my head last night after having consumed 3 pints of London Pride ale.
According to the specification for the F9Q engine, the timing belt is to be tensioned such that it reads 63 Hz or 90 hz depending on model. Tension is measured using a special Renault tool which is not accessible to normal mortals. The tool uses a microphone which is placed within 10 - 20 mm from the back side of the belt. Belt frequency is measured while lightly tapping on the belt.
Has anyone attempted measuring belt frequency using a guitar or cello tuner?

C2 = 62.84 Hz and G2 = 98 Hz. Both notes are well within the tolerance specified for the engines.

What... Just twang the belt, holding the tuner close enough that it hopefully picks up...? What an odd idea, it might just work if the belt resonates long/loud enough

The tuner app on my iPhone gives the current frequency in Hz, anyway, so you should be able to get it pretty much bang-on.

I don't have a dCi to play with though.

Try a tuning fork

and if that doesn't work, try dropping London Pride for a decent beer

As I am in the 'trade' I can exclusively reveal that Jimi Hendrix has signed a deal with Snap-on to produce a range of guitars that produce a note in tune with manufacturers cambelt tension guides.

Mind you,Jimi plays the guitar upside down so what he calls number 1 string is infact the opposite,that would confuse a stupid person....

Needless to say,the guitars aren't cheap,but hey,just like the shampoo commercials,they're worth it.

I'd rather push my Alfa than drive a BMW....

belt , dci , diesel , engine , f9q , tension , timing
