Have a polite chat to your rep
I had some do a similar thing a long while ago & Stens replaced the pulleys and a belt .
Now there is a bit of a trick here a well
If Stens list the pulley as a replacement for the OEM one in there catalogue then they will replace them
But if you have just found a pulley that is the same dimensions as the OEM one but they do not say it is a direct replacement then they will not replace it .
I had 2 plastic V Tensioner pulleys split along the casting line when I fitted them to a JD Z445 .
Now the Stens pulley was exactly the same size, but thinner than the JD one which apparently is why they do not list it as a replacement .
I usually buy a plain pulley if possible & swap the stand off bosses so I can come to grief some times but when I can swap a $ 95 Husqvarna idler for a $ 25 Stens pulley and 2 minutes press work well worth it because the customer thinks I am really good when I charge out at $ 60 .
You have to make up profits where you can
I did go the the effort of turning up 8 tubes to support the inner race but now it is literally 2 minutes on the hand arbour press .
