KAD32 Volvo Penta Supercharger Issue

[amatas08]

Hi All,

I have a Volvo Penta KAD32. I had an issue with main engine belt failing. I have now replaced this belt and all other engine belts.

When I start the engine and let it idle there is a noise that kicks in after about 30 seconds. I think it is the super charger kicking in ( as the outer pulley on the supercharger starts to spin at the same time as the noise kicks in.)

I am not reving the engine for this to happen.

If anyone can let me know is this normal as it never happened prior to changing the belts. I would of thought that the engine would need to be reved above 1000rpm for the supercharger to kick in.

Once it kicks in it does not stop, if I turn off the engine and back on the sames thing happens ( time from turning the engine on yo the noise is fairly consistent each time)


Any help is appreciated

Thanks
