7MGE air con idler pulley (Cressida - Supra)

[petergoudie]

On a 7MGE engine, does anyone know if you can replace the ball bearing(s) in the air conditioner idler pulley that adjusts the belt tension. It looks to me that the bearing is sealed inside the pulley somehow. Possibly the pulley is spun around the bearing and the pulley does not come apart.

Yes its replacable , cant remember the number maybe a 6301.

Thanks. If it is replaceable it means the pulley must be in two halves although I can't see how to split it open. Do you know how to get to the bearing?

I vaguely remember the whole pulley coming as the replacement part, rather than just the bearing


...or maybe i'm thinking of the timing belt tensioner... hmmmmmm

I've looked closer at the pulley and yes (1) I think 6301 is correct and (2) it's not intended that it be replaced so I guess they pulley & bearing is meant to be one part only. However, on the front face there is a metal disc (the size of the outside diameter of the bearing) that is held in by four small crimps of metal (you have to clean eveything to see the lines of disc). I will try to punch them back and if I do I will be able to push the bearing out of the pulley.

Also, the timing belt tensioner is one piece.
