Locking crankshaft/flywheel in 1.6 petrol TU5JP4 engines when changing timing belt (Peugeot/Citroen)

How to pin/lock the crankshaft/flywheel when changing the timing belt in NFU or TU5JP4 1.6L 16v 110bhp petrol Peugeot/Citroen engines.
The car is a Peugeot 307 (2007; 1.6L 16v petrol; 110bhp; ~47,000miles; TU5JP4 engine). This should be the same in Citroen with the same 1.6 petrol engines. Make sure that you have put the pins in the camshaft sprockets and the line at the bottom of the crankshaft is pointing down. Then you can wiggle the crankshaft tool to lock the crankshaft/flywheel. If it does not go smooth enough you can rotate the crankshaft (with camshaft sprockets locked) a tiny amount clockwise or counterclockwise, only a small amount so the tool can go in the flywheel. Do not turn too much counterclockwise.
The genuine tool is 6mm, but I had to file it to ~5.7-5.8mm. The hole gets rusty and the 6mm rod does not fit quite well. The length of the rod that goes inside of the hole is ~2.8cm.
The camshaft sprockets are 8mm, so one can use a drill for that purpose. Also, there is a U-shaped clamp to hold the new timing belt on the crankshaft, but it does not really work. I use cardboard that I stuck underneath the crankshaft to hold the belt in pace, much easier.
Here are a few very good videos of how to change the timing belt:

The next two are in Russian, but they are really good to watch of how to replace it, even if one does not understand the language:

Very helpful tutorial. I just bought a used 206 and this is one of the first things i will do

[@moremolecules]

Good luck with changing the belt. It is pretty easy actually and I should have filmed it as well...and I did not as there were several others, although not in English. Check the links in the video.

[@WorivpuqloDMogh]

@@moremolecules thank you. Yeah it looks pretty straightforward indeed. Oh its ok. I am gonna get a small lock tool so i dont mess up the timing Reason i bought this car is because i am gonna sell the new one i bought 2 years ago. I moved withing a mile to work and its stupid to pay off a car a barely use

[@dannyscholten399]

Thanks! Great video👌

Hi, your videos stopped popping up in my recommended. I see the views are low but don't stop, I love them man. Turned on the bell

[@moremolecules]

Thank you very much indeed for the support Rek. Some of my videos are for a 1.6 petrol version engine, it maybe that youtube decided that you might not be interested.

Good video, txs a lot

[@gsmith5865]

Thanks MM for that info straight to the point , can you pin the 1.6 hdi flywheel/crank from same area, I have both models the petrol and diesel

[@moremolecules]

Yeah, good question. I have not done it on my 1.6HDi, so difficult to give you a proper answer. I think the flywheel locking in the 1.6HDi is only to release the pulley bolt and not used for timing. The 1.6 petrol is used for timing.

[@Appregator]

Thanks so much. What is the length of the 6mm locking section going into the hole, if I may ask.

[@moremolecules]

I should have put this in the dimensions. Thanks for the question, it goes inside ~2.8cm.

[@Appregator]

@@moremolecules Much appreciated. All of the best.

[@Jhampa108]

thx thats great

[@mechanicus8521]

Nice

[@Snorklaren0]

The key in the camshaft sprocket broke on mine. Im going to replace it but dunno how to put the correct timing. Following your video will do it for me?

[@moremolecules]

Not too sure if my video will do it. Have a look at the videos listed in the description. One is in Russian, but pretty good. The other one is German, but with English subtitles. As long as the 3 match, there shoud not be a problem, i.e. the two camshaft and the crankshaft one.

[@FIXnMIX..]

Thanks for sharing your knowledge and expertise. I bought a timing belt (Bosch brand) for my Peugeot 206 sedan 1.6 two cam shafts. The belt has 134 teeth! I just want to make sure if it's the right one to my car? I intend to make the replacement my self.

[@moremolecules]

It is fairly straightforward to change the belt + water pump and associated pulleys. I should have made a video, but thought not. I cannot quite remember if mine was 134 teeth. I bought this: www.autodoc.co.uk/gates/7024338 It was GATES KP15581XS belt + water pump and pulleys. The belt is Gates 5581XS with 134 teeth.

[@FIXnMIX..]

@@moremolecules Yes, I'll definitely change the water pump + pulleys. One more question please. 🙏 The belt I bought has no marks (I mean the three white marks) for the crank and cam shafts. Should I buy another one with those white marks, or may I count the number of teeth between the marks then make them my self??

[@moremolecules]

@@FIXnMIX.. The marks are extremely useful, but you do not need the marks, counting the teeth is also alright. If I were you I would get more reputable belt with white marks.

[@FIXnMIX..]

@@moremolecules It's Bosch brand - made in Germany. That's what it says on the belt, plus it has all the (numbers, arrow ➡ direction and date) written on the belt except the marks! Thank you so much for considering my questions 🙏

[@moremolecules]

@@FIXnMIX.. If it is bosch, then probably alright. Just count the number of teeth.

[@yeaysindeed9705]

Hey, do you know how to fix the timing if the car has jumped timing?

[@moremolecules]

If you line up all the holes plus the bottom one, it should be timed. Do not go counterclockwise only clockwise.

[@drunkonkerosene]

Excellent

[@drunkonkerosene]

Worse is that the hole is missing on my 2003 Partner. There is to a be a marking on the crankshaft sprocket instead.

[@haveen5162]

nice video. whats the diameter of the locking tool to the flywheel?

[@moremolecules]

It is in the video description, but here it is: The genuine tool is 6mm, but I had to file it to ~5.7-5.8mm. The hole gets rusty and the 6mm rod does not fit quite well. The length of the rod that goes inside of the hole is ~2.8cm.

Merci ❤

[@carlosgilpinheiro7510]

Anyone know if flywheel is the same in all Tu5jp4 engines? I changed the engine in my 206 1st gen for one that was in a 307. After that change the engine lost power and sometimes at low speed there is no torque or became confused. I read in a forum someone changed the engine in a Xsara to one from a 307 as well and only after changed flywheel the problems were solved.

[@moremolecules]

I really do not know the asnwer to that question, but I suspect that they are the same.

[@Genakrul_93]

If you lock the camshafts with the belt on, but you try to remove auxiliary crankshaft pulley (one that has 3 screws), and if it by mistakes moves (spins), does that mean that the crankshaft moved aswell with it and that the engine is not timed properly anymore (even tho the belt was on - not removed yet)?

[@moremolecules]

How did it spin with the belt on? Unless I have not understood something. The auxiliary pulleys can spin on their own without a problem, but the crankshaft pulley at the bottom is timed with the teeth on the belt. As long as the belt was on, the pulley cannot move on its own without rotating the camshaft ones.

[@Genakrul_93]

@@moremolecules You understood correctly. Thats what I asked, was it possible for something like that to happen? So basically what I did was "released" alternator so that I can remove the auxiliary belt, after I removed that belt, I removed top cover of the timing belt, afterwards I've locked the camshaft, marked it with the marker, afterwards wanted to remove the 3 screws on the auxiliary crankshaft pulley so that I can reach the bottom plastic cover of the timing belt, but when I've tried to unscrew the pulley it spinned, and I've shitted my pants. 😂 So my question was if that outer auxiliary pulley spins, does that mean that the crankshaft spins aswell because if im not mistaken middle screw would move/turn crankshaft? Major mistake was that I didn't know that you need impact pistol for thosse 3 screws, but I've tried with the wrachet and thats how the pulley spinned. ps. forgot to mention it is PSA 1.1 engine so it has only 1 camshaft.

[@moremolecules]

@@Genakrul_93 Not too sure about the 1.1 engine, and the three bolts, as the 1.6 has only the middle and no other bolts. The auxillary do not matter in any case, only the camshaft with relation to the crankshaft one. So, you pinned the camshaft (only one on the 1.1), then removed the belt and then the bottom crankshaft moved? You did not have the crankshaft pinned? Then the timing is off if the crankshaft pulley moved with the belt off. The other auxiliary pulleys do not matter. Maybe I still do not understand which auxiliary pulley moved.

[@Genakrul_93]

@@moremolecules I've tried to link the video, but I asume it's not allowed. The timing belt was still not removed and only the camshaft was locked. And when I wanted to remove the crankshaft pulley for auxillary belt, because behind it is the lower portion of the plastic cover for the timing belt, it spinned couple of times.

[@moremolecules]

@@Genakrul_93 Ahh, that should not be a problem, as the timing belt was still on, unless it has slipped/skipped a few teeth, but you would see that slack in the timing belt. Post the link without the http and it should work.

[@orenestorovic1921]

Hello friend, I have Peugeot 307 form 2004 ( 1.6 hdi, 109hp ) does he have timming belt or chain?

[@moremolecules]

It is a timing belt.

[@orenestorovic1921]

@@moremolecules okay thanks. I thought the same, but the guy From the shop told me it has chain so I was confused. I checked engine it has plastic cover on that place wheres the Belt... So i think its Belt.

[@moremolecules]

@@orenestorovic1921 Definitely not a chain. The 1.6 petrol and the 1.6HDi are not chains, but timing belts, regardless of the bhp. Check your car booklet and you will see timing belt replacement interval. You would not have it if it had a chain.

[@orenestorovic1921]

@@moremolecules thanks a lot friend.

@@orenestorovic1921 No worries, glad I can help

[@HardiHolpus]

Is this a reliable petrol engine in your opinion?

[@moremolecules]

In my opinion, yes. It is pretty solid engine and that is why I bought it myself. It uses a bit more fuel, as it does not really have anything, like a turbo. The engine does not have much stuff in it anyway to go wrong and it does not suffer from headgaskets as compared to the 1.4 engine.

[@HardiHolpus]

@@moremolecules Thanks! So for C3 1.1 and 1.4 petrol engines are more economical, but less reliable than 1.6 engines.

[@moremolecules]

@@HardiHolpus Yes, correct. The 1.4 (not too sure about the others) and the 1.3 (Citroen mainly) are economical, but very much prone to headgasket failure, so quite a bit of mixing oil/coolant. Not too difficult to repair, but it comes back again. For this reason there are great bargains to be had in the 1.3-1.4L petrol engines, but one needs to get hands quite a bit dirty.

[@antonchokov]

В сравнение с моя Ford tdci, това е приказка.

[@moremolecules]

I completely agree, the 1.6 petrol is very easy to work on and replace all the belts.
