80 series air-con pulley bearing

Unread post by woolgoolgaoffroad » October 7th, 2007, 6:40 pm

hey guys,
the bearing behind the pulley on the air con unit, on my 80 series diesel is howling and growling. I know it is this as i pulled the belt off and it stooped, and the pulley is hard to turn.
My question it, if i undo the 10mm bolt on the front of the air con unit, will the pulley and bearing come straight off, or will i need to take off the whole unit,??? ( which might mean getting it re-gassed ).
cheers

The pulley will come off if you undo that bolt.No regassing etc Toyota will only sell you a complete clutch for about $200. I found an aircon shop that replaces the bearing with an aftermarket type. You could do it yourself if you remove the bearing and take it to a bearing distributor to size up the bearing.

If it's the original genuine ND compressor, ask your mate for a Nachi 30BGS10DST or equivalent. ;)

Once you undo the 10mm nut you will have to prise the front plate off. Once you have done that there is a circlip which needs to be removed before the pulley will come off. The pulley generally needs to be removed with a 3 legged puller. If you decide to use a pair of screwdrivers ( this does work ) just be careful not to damage the clutch coil behind the pulley.

The bearing is a press fit in the pulley itself and has nothing to do with the clutch. Either smash it out and tap a new one in or have a shop do it for you.

Are you sure its only the pulley bearing? Take the belt off and spin the pulley. Then spin the front plate of the compressor and make sure it turns smoothly

Also I forgot to mention. Once you have it all apart check the surface that the inside of the bearing sits over ( alloy nose cone on the compressor ) if its damaged in any way then you have a bigger drama on your hands

I forgot the cir clip:o It can be easy to damage the lip trying to get the clip over the edge of it.

well i took everyones advice, seek some help from our local air con place and he gave me the same advice as you guys ( not that i ever doubted it !!! )........................ took it all apart, one thing he did tell me was put a live wire to the plug on top of the air con, and this will lock the plate to the pulley-makes it easier to crack the 10mm nut on top. Easy.
Next i took the very locked bearing to a mate, pressed it out, got a new one from next door ( $27.40 ) new one pressed in ( free ) and now i am one cool cucumber.
So thanks to every one for their help.

Glad to hear she is all sweet mate, good little tip using the clutch pack to crack the bolt, I generally use air tools at work so have never had a drama
