Thread: worn bearing noise on TD5 idle

How is the harmonic balancer?

Engine bearing noises dont normally present just at idle. Rattles at start up, are often indicators of mains wear and rattles under load and mid rev ranges are usually big ends. This is by no means definitive, but a good place to begin.

wow that not what I wanted to hear.

I am looking at a head gasket as well, if it is the big ends, i might be better off getting another donk.

I have a bit of blowby, I thought that would be rings, not big ends.

hmmm

What idler pulley did you change?
Mine has no ACE so I have 3 bearings to think about.
1 on the adjuster.
1 on the idler(where the ACE pump would be fitted).
1 for the fan, mounted into the timing case.

I've found if you need 1 you probibly need another.

Happy hunting

noise has gone today. Bit weird..

I am going out now to check the harmonic balancer bolt.

I replaced the adjuster/tensioner.

I'll let you know.

Just when to check that Harmonic balancer and sure enough the pully on the Fan has a wabble. Looks like it is the one on the timing Cover.

what do I do to fix that. Rave is not much help.

Have a read of this excellent how to...

I use a narrow head 12 inch shifter to remove the fan instead of the tool mentioned.

That's an expensive bearing too. I bought a cheap one last year from a bearing bloke in my local area, haven't used it though as I haven't had to change yet but it looks the same?. How many Km's has your vehicle done Matt?.

Barry has "only" done 354,000km.

Do you have a part number still? I might be able to get one tomorrow.. never know your luck.
