Power steering tensioner

[Kscha41]

Hello everyone, it's been a while since
I've posted but I do read the forums
everyday. Today I started my 59 841D with
power steering and I started to smell a
belt burn. I got off the tractor and saw
the power steering belt was loose. I
thought no problem, I'll just tighten it
up. That's when I realized that the
tensioner is broken. Does anyone know
where I can find one? I did a quick
search and nothing came up. I'll include a
picture of what I'm talking about. Thanks
