Any body know how I go about fixing this? Do I need a whole new fan assembly? Or just the bearing case that was on the stalk? I've really got no idea and I need my L200 ute back on the road ASAP.

Here's some pics:
Do I need to replace the whole casing pictured here with the radiator hose coming from it?

Here's a shot of the bearing casing I'm talking about that was all chewed up. I was scraping bits out of the hole.

Here's a pic of the shaft, pics a bit blury but you can see it looks like some of the shaft where the groove is has been chipped off?

Thanks all for your help!
