Good post DonnieB http://i167.photobucket.com/albums/u124/Herschel1_2007/ThumbsUp.gif

I was looking to see what exactly causes the gear to get noisy.I read somewhere that it's the spring that loses it's tension causing the gear to make a noise after a while.

Re: Internals of a 20V VVT gear

its great to finally see the inside one of these, so is it true that they are almost impossible to put back together?

Re: Internals of a 20V VVT gear

The pics. of the cam gear are mine. They were lifted from an Australian site with neither a request to use them or any acknowledgement of their source. The gear is a very nice piece off work.
Since the gear is a non serviceable component it is neither designed or manufactured to enable it to be dismantled.
It would be rather stupid for anyone to carve one up expecting that they'd be able to put it back together correctly again with no leaks Sam , but why would anyone want to now they've seen what's inside & knowing that there's nothing serviceable in there?.

It's not my site but a site I subscribe to for clubman sports cars , oz-clubbies.com ,   where I posted the pics. of the gear.
What do you actually bust in your cam gears. They look pretty unbreakable to me although I can quite understand them rattling a bit.

Re: Internals of a 20V VVT gear

Is there any update on servicing/repairing the VVt gear?.I agree with superc,this gear is not so complex that it cannot be done.If its only the spring that looses tension,causing the mechanism not work properly,then its simply getting a custom spring,and that should be easy.Dropping 3k on a spring?.If its worn gears,that wont be easy if possible to repair,the seals you can get in any shape/size,shouldent be a problem.

Why was it never designed to be opened,and who said this?.It can be simply that they want to sell you parts,like with many other things.I bought one from Mike's yesterday.I will take my old one to my local mechanical engineer,who is yet to give the wrong analysis to any of his clients as far as i know...

Thanks for sharing the breakdown of the VVT. Very good to see and gain a full view of the internals.
