Oil Feed Mod for Auto CCT?

[Harveyz]

Hi All

I appreciate this is an old topic CCT and that one theory is that the front ACCT breaks due to oil feed issues. I picked this snippet up from the Honda VTR1000 Firestorm Facebook group - basically the conversation was tag unless you check your manual CCT's regularly and adjust as appropriate you can have problems etc... A mechanic on the site said he recommended ACCT having worked with Honda on the issue and said if you don't want to adjust you MCCT every 4 - 6000 mile then - "If you don't have the patience and or time for that then rather stay on acct units and have an oil feed kit installed and accept that the acct life span is approx 65-85,000km". Has anyone heard of an "oil feed kit" for VTR1000 cam chain tensioner ? It's an interesting twist. https://www.facebook.com/groups/2380556467

There is more bad, wrong, mis, guess, made up information than there is correct on faceplant. If you can't find it here or the Superhawk forum.......

Totally agree...

It all stemmed from someone whose MCCT's front fell out as the bolts holding it in wound out.

Said mechanic is IIRC from Norway & was saying Honda recommends this & that & was probably referring to Il4's & not VTR specific.

Some other manufactures use oil feed, Kawasaki use a ratchet type.

Never heard of a oil feed kit. The rear gets oil as it points down they can still fail as its the spring that's the culprit...

Boll acks! the spring breaks as its shite & not really up to the job.

Same unit is used across the range they still give up just don't wreck the engine...

Never heard of an oil feed kit... If it existed I think we would of all done the mod by now

you shouldnt have to adjust mcct for at least 25k. i had a set in an engine with 46k i think and they had never been adjusted , i fitted them at 14k, the bikes still going with a new owner and he hasnt touched them, god knows what miles he has on it now

Interesting response - was expecting something a bit more articulate not keyboard warrior time - the lubrication issue is well documented on SuperHawk site - I know that SV650 Gen 1 has same design type as VTR1000 - Gen 2 switched to adding a racket mechanism too prevent retraction and later Gen 2 has lubricated camchain tensioner using oil pressure - SV650 is a also a 90 degree twin - so worth some meaningful discussion - or perhaps Suzuki's engineers like to talk baldrocks as well

I think the flaw in this oil feed hypothesis is the fact that sometimes we also see a rear CCT fail too, and due to the position on the bottom of cylinder they are sitting in oil all the time…… so lack of lubrication between the spring coils reducing the fretting corrosion might be a contributing factor which results in the front CCT being the more common failure, its not the root cause of the problem. …. That is still a sh1t fatigue life on the spring

Hahahaha. Go follow the superchicken thread & report back when you have solved the issue please.

I agree with Al

While I think an oil feed to the front ACCT may possibly extend the life of it to a degree, I can't see it fixing the issue completely. As Al says, the rear ACCT's which are sitting in engine oil all the time still fail, admittedly not as often as the front ACCT's, but they do still fail unfortunately,

If you're going to the effort of installing an oil feed to both cct's you might as well install ones that tension by using oil pressure.

I found that adjustments for manuals was rarely needed, ten k plus miles at the very least.

It could be spring fatigue as the tension retracts on the overrun, but that doesn't explain why the vast majority of CCTV failures are the front one, so the upwards pointing aspect preventing oil reaching the spring is a major factor, imho.

But then I'm only a keyboard warrior like Mac, so whatever. Do what you like.

This is the same noob who thinks indis on perm is cool...

cups hand over mouth & makes whooping sounds like a native american...woo woo woo

I'm off to me Tpee...

I'm so happy you found someone to form your own little tribe - if your lucky he'll share your teepee and if you're lucky adjusting your MCT - noob, noob

This comment is why I have blocked you.

Since my first Storm in 2006 I've had over 20 of them. There are 8 in the cave at the moment.

Tony has worked on more Storms than anyone on this forum.

I know enough about them to be dangerous but would always ask Tony if there's something I need to know.

Between us I think we are a bit more in the know & hands on than your good self regarding Storms.

Good luck with your oil feed research, have a good day & as they say on ya bike...

Over & out...

Ah, well, Facebook's gain.

But he's partially right- my daughter is having a civil partnership celebration on Saturday and for reasons best known to herself and her partner-to-be she has invited all the guests to go on a 5k park run on Saturday morning dressed as cowboys.
I, of course, have bought an Indian outfit to wear. (If I set off first it'll give them something to chase).

Sadly, no tepee, though.

Couldn't work out "how".

[Cedardrew]

From my understanding, the oil feed mod (if there is/was one) would only prolong the failure of the spring so still isn't failsafe. I performed the stopper mod on my new front tensioner (previous one failed) and original rear tensioner (hasn't failed... yet...) so at least when the spring goes bang, which it will eventually, it won't eat some more valves with it.
