Could you please list when changing chains which sprockets (gear wheel) should I replace? Thank you!

[@yd2532]

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

[@chrisdownes2974]

Does your kit provide different size shims for fuel pump sprocket?

[@Ozziegarage]

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

[@yd2532]

Yea vacuum pump is the only thing that needs loctite

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?

[@yd2532]

Single row chain is prone to snapping so we upgrade to double row

[@aznpride009]

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?

[@yd2532]

Yes that's normal

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?

[@yd2532]

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

[@123Didrik]

Hi mate, why did the fuel pump shim size change at all ?

From factory Nissan has the wrong shim on them most of the time because they cant easily check alignment because the vac pump sprocket has 2 floating rings around the teeth. That's why the chain life varies so much because of the factory alignment

[@yd2532]

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

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.

[@Davo_1991]

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.

[@yd2532]

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.
