I could not find this information. Other manufacturers, such as Subaru, advertise clearly their use of a chain. Does any one know what Honda is using ?

I have seen several description of the Honda CVT but they say noting about the material used for the belt. They all mention a 'belt' not a chain.

I could not find any maintenance requirements that mention changing the belt as they used to do for the timing belt. Some claim that the CVT belt it is simple to replace. I would have expected a schedule for preventive replacements.

Also, does anyone know if the engine is fitted with a timing belt or a timing chain?

The 2008 Fit had an non direct injection engine of 1.5l using a timing chain. I think the next generation Earth Dream engines with direct injection are also using a timing chain.

speaking about this, what is better, a chain driven or belt driven system?

Yea, that is what I was wondering. Is one better than the other? Is it something to do with how it performs, or just about cost/durability?

My understanding is that a chain will last the life of the engine while a belt needs to be changed every 100,000 km. May be a rubber belt is lighter and quieter.

Timing chain is great news. Less maintenance. I hate expensive timing belt services.

No kidding, just spent almost $900 today, replacing timing belt, drive belts, water pump, and numerous leaking seals in my Rav4.

 

[hondaguy]

Yeah it gets expensive to change them, reason why when it comes to cars I daily drive, i only like to keep them for a few years, get rid of them before all the major maintenance stuff comes up.

Keep in mind though, Nissan has a chain driven CVT that is a borderline unmitigated disaster...

That's what I heard and sort of what I was trying to eventually get at with questioning whether belt or chain it better, could have been better chain systems before.

Pretty sure its a belt as the pulleys are variable diameter ...also see this stories graphic in article

Since HRV is based on the FIT - 2015 FIT article below states "A newly developed high-rigidity drive belt, "


"Continuously Variable Transmission with G-design Shift
Available on LX and EX models and standard on the EX-L is a new Continuously Variable Transmission (CVT) tuned specifically for the Fit. While providing greater fuel efficiency, the CVT also delivers more responsive and linear acceleration compared with the previous five-speed automatic (5AT) as well as conventional CVTs. Several aspects of the new CVT assist in this dual benefit.
A new-design torque converter that is thinner but with an increased capacity optimizes the transfer of the engine's power to the CVT for improved linearity in engine speed relative to throttle application, and it eliminates the excessive engine revving common with conventional CVTs. The new CVT has a 14 percent wider ratio range that allows the engine to operate in a more optimal range for both good performance and improved fuel efficiency under all driving conditions; this is especially felt with reduced engine speeds at higher vehicle speeds. A newly developed high-rigidity drive belt, new CVT fluid allowing reduced pulley pressure on the belt, and a CVT warmer further extend the unit's efficiency.

Whether it is a belt or a chain, its length is constant. There are input and output pulleys, as one gets smaller the other gets larger, to ensure that a belt with a fixed length maintains full contact.

A newly developed high-rigidity drive belt,

This description and many others refer to a high-rigidity belt. If it was a metallic belt or a chain, I think Honda would have said so, as many of their competitors do.

My conclusion is that Honda has opted for a re-inforced rubber belt. I trust Honda's reliability engineering, however I would have preferred to have metal pulling the full weight of the car.

Oil on the differential

I have a HRV model 2005. Does anybody know anything about the procedure for changing oil on the differential?
it seems there is a special procedure to be followed, not only fill up with oil....

As this forum is on the upcoming HRV and not the old one, you will have better luck on some forum about that gen or on some massive general honda forum like.. .honda-tech dot com

The original question I believe was targeted at the timing mechanism. Honda changed over to using only timing chains on their 4-cylinder engines 10+years ago I believe. The 6s still used the timing belts.

The CVT will need some sort of belts, no doubt.

 

[k1ng]

I much rather have belts, especially going off of the reports about what people have been experiencing with chain driven systems.

I agree.
