Engines D5/D4/D3 Crankshaft Belt Pulley / Oscillation Damper

[hal9000f]

Acquired a beautiful MY2013 V70 D3 D5204T7 six months ago with 150 kmiles on the clock.
Timing belt job was done 30 kmiles ago.
Both Aux belts were also done 30 kmiles ago.

But, the Aux tensioner, Crankshaft belt pulley and Alternator freewheel pulley were not replaced.

So, planning to replace everything on the Aux side ASAP because I am aware of the Aux belts peril.

But, there is a problem with immediate crankshaft belt pulley availability.
Hence this thread.

My question is what is your experience and recommendation at which mileage or years to replace
crankshaft belt pulley and alternator freewheel pulley?

And has anyone experienced the crankshaft belt pulley failure? Is it sudden or you can see, hear or feel the announcement in advance?

Same question for Alternator freewheel pulley.

Thanks.

I read or watched a video where the outer of the crankshaft pulley had separated from the centre drive part. It is an expensive part from Volvo, alternative is available for less. They were not sure if the failed one was original or not I think, and I think it was very high miles/km as well.

They were lucky they noted the aux belt moving over on the pulley by a few ribs before and did not realise why it happened. It was because the crankshaft pulley outer was separated and moving outwards.

Crankshaft Belt Pulley - Assume this applies to the 2.4D as well?
Any part numbers please?

That is for my V70.

Cannot be sure that it suits yours!

It probably does.

Ok will check, thank you.

Edit: yes it does - will add to my job list!
