Its not really that bad at all, as timing belts go this is one of the easier ones to change, on some Audis you have to take the front end off, on some Alfas you might have to take the engine out, to access the timing belt. The only hard bit is getting the tension right. Apart from the elusive SEEM unit machine the haynes manual wants you to use to set the tension (most mechanics ive asked just set the tension by feel) a set of ordinary tools will get this job done.
Seems like one hell of a job. Do you think its this hard to do because Peugeot wants you to use their mechanics?
You can try marking the belt and sprockets positions with tippex, but personally i prefer to lock the flywheel, the starter is not hard to remove, the wee bit of extra time locking the flywheel is well spent in my opinion.
As for the removal of the crankshaft pulley, try and loosen it off with and impact wrench before locking the flywheel, the locking bolt in the flywheel could snap when undoing the pulley bolt which is not good.
My pug 406 2.0i does have a hole in the crankshaftpulley, is it necessary to lock the crankshaftpulley in place, when changing the timingbelt? And is it better to remove the crankshaftpulley before locking the camshaft in place?
i thought that. thought he was looking for crank locking at 1st lol
I took the starter off to get to the flywheel, which is connected directly to the crankshaft has holes on it which line up with holes on the engine block this helps to set and lock the engine to top dead centre (TDC) You could just use the paint marks technique but i find this way handier it doesn’t really take very long to unbolt the starter.
hello , just a simple question , why did touch at your starter moter I don t think it matter for changing the timing belt ?
pulley OK, no rattling. i filmed the noise, but then managed to find that one /watch?v=RwjGfJEmBwo which has exact noise.
engine already ran to full heat, to engage blower fan, also a short ride for coolant top up. Everything else is fine.
Prior to that, turned engine numerous times, holes did match, even though i decided to do belt change it with correction fluid only, i removed the starter afterwards.
Thats the tensioning technique, also turn the engine over with a ratchet a few turns to check everything is moving ok with no interference and that the alignment holes meet up again.
What condition is your crankshaft pulley in?
Did everything, belts, pump, coolant, thermostat. Got strange running noise. Searched through videos.its the timing belt. Too tight, even though can twist 90° but I dint fully understand the tightening technique in the link desciption (406.co..).
To sum it up, press gently the cam bolt toward left, to tighten the longest run belt.
If in that position you can turn the manual tensioner wheel by hand, it is OK. If you cant turn it – too tight, and if it turns too easy, its to slack.
Yip correction fluid would work fine, i just decided to show locking the flywheel to make the video more complete, its only about a few mins more work.
One advantage of locking using a pin in the flywheel is that if the old belt was slack or perhaps off by a tooth then if its correctly locked when the new belt goes back on it should be correctly positioned.
Thanks for your comment
Do you think it is absolutely necessary to lock the flywheel? it’s such an extra work.
Maybe just locking up the cam, than, with correction fluid, drawing a line through any cam sprocket tooth and over the old belt, and another line through crank pulley tooth over the belt.
Removing old belt with two lines (market top and bottom), copying lines at exact same positions on the new belt.
Mounting the new belt with copied lines to the same marked positions on the cam sprocket and crank pulley.
Thanks for the comment.
excellent work. very good explanations. thank you so much for uploading this video explaining how to do the job
Thanks for the comment
Yip its a fairly ackward place to lock the crankshaft, id seen pictures of it being locked but it still took a while to figure it out.
Great video. Thanks for sharing.
I could never find timing hole for crankshaft but now I know where they have hidden it.
Thanks, luckily I’m not that bad…..managed to change a headlight bulb last week…..woohoo : –))
An acetylene torch or Stihl saw 🙂
Only joking, open the drivers door, down on the A pillar beside the accelerator pedal there is a handle, pull it back and the bonnet will pop up.
How does one open the bonnet? ;-))
