Crankshaft pulley

marpate1 · Post by **marpate1** » 02 Nov 2005, 12:06

Hi all,

Constant squeeking from the engine area, so I pulled over to take a look. The crankshaft pulley is loose.

I'm ready to take the pulley off, but the bolt won't shift.

Is a left or right handed thread? Where can I get a replacement?

What damage would it have done (seems to be quite a lot of oil around it and the bottom of the engine)?

Really need the car back on the road today, so any advice welcomed.

Thanks,
Mark

The bolt is very tight, you will need a socket and at least 3' extention bar to get enough leverage. If the bolt is tight, the key must have worn or be broken, you may find that its worn a nasty groove in the crankshaft, unless its a damped pully, in which case it may be in two sections with a rubber insert between them and it may be this thats gone. I hope thats what it is!

Hi Peter - you were right

The key is very worn and has made a right mess of the pulley. The crankshaft does not seem too bad. I'm off to the local GSF to try and get the pulley, but they don't stock the bolt. The nearest is a 30 mile round trip for a £2.80 part.

If you have any comments for the installation, please let me know.

Thanks,
Mark

It's similarly very tight - about 30lb/ft, then another 60°, and it has thread lock as well. If you buy a new bolt then it should come with thread lock on it already. How come the pulley was loose if the bolt was tight?

Hi,
To get crankshaft pulley bolt undone easily, fit a good socket or ringspanner on head of bolt, turn crank so that spanner/socket is jammed against body ( anticlockwise ), then just give starter a flick. Instant bolt undo.

Hi, I really don't know - it makes no sense to me.

I've just come back from GSF and they don't stock the parts I need either (93 1.9TD).

Looks like off to main dealer instead then

Thanks,
Mark

Ha! You really make it sound so easy. In fact, this is what I did in the end. Even doing this, the bolt was damned tight and I needed to do it a few more times during removal.

Well, I'm having trouble finding somewhere which has a pulley available quickly. Other than GSF, eurocarparts and buypartsbuy - does anyone know of anywhere else I can try ... or is it really only citroen?

Thanks,
Mark

Only a scrap yard.

Let me explain this better. The bolt itself was very tight in the hole, but it looks like the washer is very worn. This was probably caused by the pulley seemingly being able to rotate 360 degrees after destroying the key. I guess that over time it just got worse

My concern is that if the key slot is damaged, then I could see the whole thing again more rapidly.

Anyway, I've found a breaker who will get a pulley off a car and I can at least inspect that and the key to check for any wear.

I've also just bought a cambelt as I really don't want to have to remove the pulley in the next few thousand miles.

Cheers,
Mark

You should be able to tell easily if the keyway is worn. The key should be a secure fit, with no slop. Make sure that you get the correct replacement key, too, to avoid possible trouble later. Not only the dimensions, but the 'shearability' varies, to limit damage if something seizes.

I know you are in a rush for a repair...But this is quite a long job.

I would go to the Breakers for the pulley (Take your Big Bar)the cars there are usually off the floor and if your in luck some are stripped down so making the removal process a bit easier.

I have just bought a pulley bolt from my Local Citroen Dixon for £2.00 and this included new locktight, trust washers also available.

To do the job right you could do with changing the Timing Belt and if like you say there is Oil around there could be an Oil Seal to replace if not this could contimate the new pulley and belt.

Hope this helps

Hi, yes you are right. Luckily my local friendly breakers will take the pulley off for me, so I will go and collect today.

I'm not sure where the oil is leaking from, so will change the oil seals as you suggest.

Thanks,
