I've just replaced front cover gasket on my 140kw 2.5. the plastic timing guide fell out as I removed the cover. It has one raised edge. Is that meant to be towards the engine or the timing cover. Yellow plastic piece.
Crank, vacuum pump, fuel pump sprockets need to be changed as they wear the most. Cam sprockets are already double row and do half the revolutions of the crank so they don't wear as much as the rest
It might have been asked already but I’ve looked through the comments and I haven’t see anyone ask but at 1:55 in the video where you put lock tight on is that the only place I should be putting some? Cause I feel stressed thinking that all the other bolts and nuts should be fine without lock tight.. great video tho I’ll be using it as a guide very soon
Howdy brother, you are the Best....how easy u make it look and how u explain it so dam well...i bought a good quality Nasser kit but still not confident to do myself...i wish u were here in Adelaide cos i would pay you to do mine....Thankyou
Great tutorial mate. I followed your exact steps but afterwards when I rotate the crank by hand the timing marks on the chain never line up again with the dots on the gears. The dots on the gears always line up correctly though. Would this be okay?
Hello, why do you remove the lower chain single and then put on a double one with double sprockets, isn't it originally a single chainring with single sprockets?
Hey mate, I’ve got a YD25 with 112k on the clock and wondering if this is something I need to be looking at a certain amount of Kms on the odo? Or is it just something for when you’re looking to put more power in, ie bigger turbo, more boost?
When u removing the tension cylinder you are putting in a failsafe. Where can I buy that one? Or did u make it? What’s the measurement if i need to make it my own? 😇
hello. tell me, why did you install this ring in the upper tensioner at 8:55? is this a spacer to increase the length of the pusher? is it included with the new chains and tensioners? What is its size?
Great vid. Have watched a couple of times. Many thanks. I have a couple of questions: - What are your thoughts on doing this job with engine in vehicle? How much harder is it? - Another YT channel with a lot of YD25 experience reckons you should never turn the engine with a socket & bar on the crank. It can cause the chains to skip a tooth?? If this is true, what's the best way to rotate the engine when doing a routine inspection of the chains?
Can only jump a tooth when the chains are super worn out or sprockets missing teeth. If the parts are all brand new and the fail safe is in the tensioner it's won't be able to jump. We replace the chains in the car 9 hour job for a d40 and 15 for a d22
If the chains are good you could just replace the tensionor, make sure it's genuine. Otherwise here is the Link to the timing chain kit fitted www.yd25.com.au/index.php/services/yd25-duplex-timing-chain-conversion-kit
I have rebuilt motorcycle motor and gerboxs. After watching 2 minutes of this video, I decided to get a real mechanic to change the timming chain. Thank you for this video.
None of my chain lines match up and there's only 1 yellow indicator per chain. Can I just line it up with fuel pump and check cylinder #1 is at TDC then mark the cams?
When you pull the car apart the colour links won't line up. Mine does because I put the chains on for the video. So just put crank to 12 o'clock and pin in fuel pump and your good to pull apart
Torque to 60nm with rattle gun lmfao yeah right bud... Also its best practise to have dot on counterweight/balance shaft gear that lines up that tooth in between the two dots on the crank gear. Not 100% necessary but best to do and cyl 1 should then be on compression tdc. And the cam gear dots should align with the dots on the timing case.
Before removing the old bottom chain and sprockets you can replace the vac pump sprocket with the new one then lock the fuel pump and torque it but the worn chain jumps sprocket teeth.
Great tutorial gives me confidence to attempt this task myself. Do you have a tutorial on actually removing the engine from the vehicle ? Regards Henry
Hi, I'm replacing my top chain on my yd22 170,000 mile xtrail, I noticed you didn't change the cam gears, is there any reason for that and would you recommend I do or should I replace them all or will they be ok. Tnx in advance.
Cam sprockets are double row from factory and do half the revolutions of the crank so they last the longest out of all the sprockets. If you do replace them make sure you hold the cam by the first lobe with a big shifting spanner with good flats on it. Don't hold it by the hex in the centre of the can cause you will either round it off or it will start to twist the cam from the torque 144nm
i have a 2.2 diesel engine. Its done 1,20,000 miles . Regular maintained. Early interval 5w30 oil changes. How much should I expect timing chain to last more? What would be significant symptoms of timing needing a change? Although on the other end of cams , vacuum pump chain sprocket had slacked at 1,00,000 miles . I did a work around and gave the needed tension to the tensioner guide. I noticed the teeth on pump sprocket one thin , but its working just ok since then. Please guide me about timing, how long do they last on good maintained.
@@yd2532 Cheers. I have to do the timing chains so I figure I should do the conversion while I'm in there. To confirm, you need to know which Vac pump mine has and do I just email through the website to order?
Genuine tensinors are the best but the top ones are prone to failing (rattling on startup till the oil pressure light goes out) The fail safe takes up the air gap in the tensinor so if it does fail it doesnt have enough slack to jump teeth.
