My 1973 XJ6 has a locked up tensioner pulley. Pretty sure the part # is 207145 But I cannot find it in USA and costs $217 plus shipping from overseas. I am hoping someone has a source for a replacement one that I can buy or order from the USA.
thanks.

can't the bearing be replaced ?

Check with David Boger - EveryDay XJ. Great guy to deal with.

I have no idea, It is a sealed unit but I will take a socket to it this afternoon and see if I can get it apart.

pressing old bearing out is safer than smacking it. Machine shops do it all the time. Or rent a ball joint puller from auto parts stores. See video below:
