Sanya no-one is suggesting this is changed out every year or 10k service but as it's rubber in the middle I would hazard a guess in the region of ten years somewhere in real life and for safety the OEM would probably go with 6-7 years so yes I would concur with Swamps on this one and suggest in line with a cambelt service. Phone Toyota though as you would think that they could tell you. It may well be that it is in fact not classed as a service item but left as a failure item like a lot of other parts. Fact is there must be hundreds of thousands of cars out there with rubber dampened crank pulleys ticking away waiting to fail. I believe white supra boys crank pulley let go on his N/A came fully off and got dragged up into the tensioner that smashed a load of his ancillaries and into the cambelt which shredded messing his engine up.
