Crankshaft Pulley Noise (Relay 2008)

[carl13671]

Hello all,

Ive recently started to hear a knocking noise a few minutes after starting from cold that I think also is causing a whistling noise when driving.

I removed the wheel arch cover today and stuck my head in trying to find this noise and it seems to be the crank pulley.

How easy a job is it to do,,home or garage?

Im hoping to do it myself to eliminate this before I start looking at the p/s pump or alternator.

Will I need stretch belt kits and pulley pullers etc?

Thanks for any help.

If you put two dabs of white paint or tippex on the pulley, one on the inside section and the other, inline on the outer, when you rev the engine you can see the outer dot moving out of line. Doing it yourself, probably the hardest job will be getting the centre bolt undone.

Thanks for your reply john,

Yeah I figured it would be a pain getting the centre bolt out.

I'm planning on putting it in gear and swinging on the sucker.

I was more worried about getting the pulley off and belts without the use of special tools.

Has anybody actually done this job at home without the need of special tools??

Thanks again

Just realised it has 3 bolts holding the pulley on.

Should make things a bit easier to remove.

Citroen's procedures say to remove the crank pulley 2 bolts furthest from the steering pump and slacken the 1 nearest by 2 cm. Then pivot the pulley off. When refitting, fit the last bolt and the belt and then rotate the steering pump pulley clockwise to turn the crank pulley so the other 2 bolts can be inserted. The 3 bolts should be done up 45 Nm and then 120 degrees. It says to lock the flywheel but a long screwdriver held between the 3 bolts on the pulley might be enough to stop it turning. It also says the pulley should be checked to see if it is warped using a special tool, but being a new pulley it should be ok.

 

If you have aircon, then before undoing the crank pulley bolts, the aircon belt tensioner needs to be released using a square pegged tool to turn it anti clockwise and then using a pin in the tensioner at the top to hold it.

 

I have edited your profile and put your van info as your signature since it helps when help is needed and saves you mentioning it each time. I do not know the engine power so you can add this later but for the above have assumed it to be 100 bhp.

 

I have slackened crank pulley single bolts by putting a spanner/socket on them with the other end on the floor or a suspension bit and giving a quick flick of the starter motor - not advisable but it has worked. A flywheel locking tool would be best but I have never had any success putting it in gear and with the brakes on. Some of the Citroen engines need a special procedure to undo these bolts if they get tight as they are undone, otherwise they can snap.

Thanks Paul,

I use this when Info when I do it,thanks again mate.

Its a 120 bhp pal.

Just checked the procedure against the 120 bhp engine and the procedure is the same except to lock the engine it says to put in first gear and then fasten a long bar on the front right wheel hub in place of the wheel and to hold this. Also the engine should be cold so the drive belt is not damaged.

Thanks mate.

Ill update when ive done it letting all know what I have broke and how many fingers ive lost.

Cheers

Just realised it has 3 bolts holding the pulley on.

So it's the same as daughter's Pug 306 and it's a doddle to take off.
