Fanbelt Tensioner Pully Part No / Wanted

Recommended Posts

The pully on my fan belt tensioner has shed it's outer metal ring upon which the belt normally sits :eek: . The belt has worn a groove into the rubber inner upon which it now sits but obviously I'm wanting to replace the pully A.S.A.P. Does anyone know the part no and whether the pully is available alone, eevn better still does anyone have one for sale :) ?.

The fan belt (correct name auxilliary drive bely) tensioner is an all metal affair, i think you really meant the crank damper has shed its outer ring? Haven't a part number to hand, but several people here have renewed theirs. Getting the bolt off can be fun without a poweful stubby impact gun.

That's the bugger :) . Thanks to both of you for taking the time to read my post & reply. Seeing as you were both so helpfull in the first place I dont suppose there's any harm in asking if either you fancy lending me the £182.19+vat :eek: that Toyota want for one do you ?. Go on you know it'd make you feel good :p .

Chris do you have any hints / tips for easier removal ?, bearing in mind my mechanical simplicity !!.

Yeah I have given that some thought but I'm not aware of / can't see any benefits over the standard one, would someone be so kind as outline them to me please:) .

The crank pulley will have been tested to the projected lifespan of the engine, or whatever Toyota's benchmark durability target was at the time the 2JZ was developed - in reality probably no more than 120k to 150k miles although I can't be sure of that. As long as the pulley survived these tests there would be no way of knowing whether it would soldier on to 200k miles, or fly apart at 150001 miles.

 

Several people have had the rubber separate and the inertia mass come off the hub. Initially it was thought that this had been caused by application of heat to the crank pulley bolt during a cambelt change but one or two people have categorically stated that this had never been done to their cars and the pulley still failed.

 

It's not a catastrophic failure if it does come off so due to the cost I wouldn't replace it at the second cambelt change as a matter of routine (unless you are rolling in it, in which case it would be worth getting dne for peace of mind). Well worth a regular visual inspection to see if the inertia mass is working its way forwards off the hub.

 

Incidentally, I always though that the "uprated" pulleys were cheaper than the stock one, hence another incentive to fitting them. I struggle to see how a component that removes a major and important function of the stock part can be described as "uprated".
