Nissan Pathfinder (VQ40DE) Timing Chain Replacement
HTML-код
- Опубликовано: 5 сен 2024
- This is how to replace all 3 timing chains, guides, and tensioners on a Nissan VQ40DE engine. This one happens to be in a Pathfinder but process is the same for any VQ40DE. This is not a quick or cheap repair but is thousands of dollars cheaper to do at home rather than taking it to a repair shop. Just make sure your mechanical skills are up to par for this level of repair before starting. I would put this at a 6-6.5 out of 10 on the difficulty scale.
I’m not a car guy, but I’m glad to see you back on the air. That means you guys are OK.😁✌️
Thank you very much. You did an excellent job. It was really nice to see you could do that with the engine in the vehicle.
Please I can’t find any details about retiming nor anyone to explain I’ve started to do this same job and my only mistake was not setting TDC before removing main tensioner and main chain retiming is needed how?
Just roll the crank over until number one piston is all the way up and the crank pulley timing mark also lines up with mark on block. What determines TDC is the cam position when #1 piston is all the way up (comes up twice per cycle). If #1 is at top and cam timing marks are lined up then you are now at TDC.
@@MrFixitTV it worked I really appreciate your response it was fast!!!
Nice vid! Can you help me with two questions as I'm in the middle of this job myself:
1) I've read about the "rope trick" on several places online - does it help you 'lock' the engine timing like using a flywheel locker? How do you do it? Is it at TDC? I just don't fully understand.
2) following that, I didn't purchase the flywheel locking tool. Do you have any tricks or a combination that work best to lock the flywheel? Unfortunately, I forgot to put the vehicle in gear and 4LO before starting this job. I had planned on jamming the flywheel from the transmission access hatch and maybe also the starter engagement spot. possibly also using a pipe-wrench on some of the pulleys before breaking the crank pulley free.
Dope. Im bouta order this crap tomorrow..with water and oil pump. Its gonna be 112 outside and thats where the repair will be done. Video was a good sneak peak.
With that slack on the right side of the chain, did the chain jump a tooth or did you hold it to prevent movement?
Shockingly it had not jumped time yet. It was loose enough I think it physically could have under the right conditions. It lived about 10k like that though. Main problem was it slipping on the water pump. It was that loose. When we let it idle and it was hot outside it would try to overheat...
This engine design is a shitshow
