Serpentine ancillaries

[GJR]

Hi all,

I’ve recently noticed a whining coming from the pulley located behind the swirl pot, shown in the picture below. My car is non-PAS, but I believe this would normally be the location of the PAS pump for a car with assisted steering.

I’m assuming the bearings are going, but I’m struggling to identify replacement parts on the usual TVR sites. I’ve seen plenty of PAS pumps, but nothing that states specifically that it’s for an unassisted car. Would the pulley for a non-PAS car be sold as a complete unit (pulley wheel and mounting bracket) or as individual components?

I’d appreciate it if someone could point me in the direction of this part(s)/part numbers, thanks.

Apparently you can skip that pulls out with a shorter belt. That’s what I’m thinking of doing.

Are you sure that it's the bearing that is noisy. Try spraying the belt with WD40 whilst the engine is running, if that quietens it then it's likely not the bearing.. With the belt off can you rock the pulley and is it noisy when you spin it?
If the above points to a failed bearing then you should be able to obtain a bearing online quoting the part no. stamped on it.
This is the bearing in question though it seems very expensive...try from an online bearing supplier.

Hope this helps

Thanks Alex, I’m pretty sure it’s the bearing. I sprayed some WD40 on the shaft between the pulley and bracket while the engine was running. Within seconds the whining ceased.

Thanks also for the link, they make it clear that the idler pulley is no longer available as a complete unit. As you say, as bit pricey though!

That’s correct, the part has not been available for a long time, however you, or your local machine shop, should be able to press a new bearing in.
