Timing belt Mhz

[Clarky5150]

All ready to pop my refreshed engine back into the S4 but just want to check the belt tension specs. Will be doing it via Mhz as I don't have the deflection measurement equip and do my Ducatis in this manner. Could someone confirm the correct Mhz please.

 

Thanks in advance

Spec is between 110 - 120 Hz not MHz

also the crank position is different when using frequency method.

This is not correct.

Spec is between 100 - 110 Hz

Engine at 30° BTDC with the colourd timing dots pointed to each other, they will not be in line.

This is for the engine with a HTD (rouded tooth profile) belts.

What equipment are you guys using for this - the Clavis gauge is so expensive!

Thanks

Gates has a good (free) app specifically to measure belt tension.

Mobile phone with Gates Carbon Drive app.   NB Older version of Carbon Drive is better than the newer versions, so I re-installed an older version and suppressed it from updating
