Honda NC750X /NC700 Cam Chain Tensioner Replacement

This video Explains how to remove and replace the Timing Chain Tensioner on a Honda NC750X, NC700 or similar motorcycle. Prior to working on the bike, make sure the engine is cold and the Battery has been disconnected. I am not responsible for any damage to your bike if you follow this video.

What a guy! Completed most of this job one handed ❤

Thanks for the video. It’s very informative.

[@ronfernandes2884]

Glad it was helpful!

[@davidwegs1]

Great help. Thanks

[@arturkryspinus3234]

did you have to secure the timing chain somehow to remove the tensioner? if you remove it to replace it won't it mess up the timing with loose chain??

[@nomoreblahblah]

Good video and instruction

[@dirtymotorcyclevagabond]

Hi, thank you for the video. It not necessary to remove the thermostat housing as the manual says?

[@j.fernandes9884]

Very well explained video, wish all videos were so detailed. Thanks for doing this.

[@josimarromerosanchez8942]

perfect.I need that chain tensioner. I'm from Peru and they don't sell them here.

[@ronfernandes2884]

If you find a good welder he can weld it for you - you can also source it from eBay

Webike...yo lo compre por $100 usd envío incluído...tardo 5 días en llegar a México

Perfect 👌 thank you for video

[@robans]

How did you diagnose the problem? How did you know that it was chain tensioner?

[@ronfernandes2884]

I opened the tappet cover several time before realizing that the plunger was not in the correct orientation _ I compared it to another video of someone adjusting the valve clearance.

[@1824reyes]

Do you have a video or sound of how it used to sound before you replace it?

[@ronfernandes2884]

I did not record that- I wish I did however.

@@ronfernandes2884 Hello Ron, I think I have similar problem. Could you listen and tell me if the noise was similar to yours? here is my video : streamable.com/046zpj

[@ronfernandes2884]

@@burakonthebike2799 Yes this is the exact sound - Your bike sounds worse than my bike - Pretty simple to fix - do not ride it on a long trip because the parts can breakoff and fall into the sump which may be harder to remove - For additional questions about replacement please do not hesitate to message me.

Do you know if a 2014 nc750x motor would fit In a 2012 nc700x?

[@ronfernandes2884]

I’m inclined to believe it’s the same because theses bikes are not like cars where they change all the hardware in the engine.

[@gavsmith43]

I realise this is a fairly old video, but do you remember if you also had performance issues issues at the time? Appearing like the engine misfiring. Revs going up/down whilst just idling?

[@ronfernandes2884]

sorry for the late reply - yes it was inconsistently firing when idling.

[@samuelalam7564]

Hi is this in the UK ? If so how much was the replacement parts

[@ronfernandes2884]

No this is in Canada. and since this happened during covid and the dealership had no stock with a long lead time i got it off ebay(US) normally cost under CAD$100 - Paid just over with the shipping.

[@nutellamitpeanuts]

Hi, how old is your bike, and how many kilometers did your nc run ?

[@ronfernandes2884]

The Bike is a 2014 Honda NC750X and it had 25000km when I purchased it used. now it has aprox 40,000km.

[@RobertSmith-bh5cv]

I'm shocked the tensioner broke. Have you heard of others breaking? There are NC owners with very high mileage and they haven't reported having this happen.

[@ronfernandes2884]

yes you’re right - even I wasn’t convinced that it was a broken tensioner at first. I’m guessing it may have been me riding it hard.

@@ronfernandes2884Mine broke around 14800 kilometers (~9200 miles). It didn't break exactly like this, but a little tab broke at the bottom which allowed the tensioner to move and the chain ran sideways on it. Visually it looks like it's made from the same metal/alloy. Expensive repair and this shouldn't happen at all. Disappointed in Honda to be honest.

[@MrCommuterUG256]

How hard bro was your riding?!!

[@gaborcsongradi1060]

Hi. What was the sign that the dreamer was broken?

[@ronfernandes2884]

Yes the rattle was felt between 700~1500rpm - and quite easy to inspect once you open the valve cover.

[@andreinabernal8907]

Hola, porque sucede esto? . Tenemos un NC 750X 2020 CON 16.000 KM

[@agustinlopez1220]

It took over 3 months to realice why the motorcycle vibrated,i took it to diferent mecanics til the honda dealer chanche the piece.

[@ronfernandes2884]

Good for you bro 👍

[@sidzephyr2519]

Seems like a very bad design by Honda. For most motorcycles, the cam chain tensioner is EXTERNAL and can be replaced quite easily. This one is INTERNAL to the engine and is a shockingly bad design. Honda should pony up and pay for these cam chain tensioner replacements as it appears to be a metallurgy issue.

[@ronfernandes2884]

So true. The screw under the thermostat cannot be removed so you would need a slim wrench to get at it until you back off the threads holding the tensioner.
