Adjustable cam gear install.

[Jay95R33]

are you sure, dont mean to add confusion but i was positive it was the other way around??????

Yepp, positive. Pop outside and see which way the crank turns when the engine is running.

yeah i understand the engine rotates clockwize but wouldnt turning the centre of the pulley clockwize advance the cam timing not retard it????

im sure the centre of the cam goes counterclockwise to retard

And here I was feeling stupid for not knowing which way it was supposed to go. It's good to see a healthy argument about it, I feel less stupid already

Damn, your right. Sorry about that.

To delay the cam (the cam is fixed to the center of the cam gear) the centre of the cam gear should be turned counter clockwise !

I was thinking of it the other way around

My bad.....

Jay, does this mean you've adjusted yours in the wrong direction? Or you just forgot which way you did it until now.

[JimX]

Ok I've got my 2 degrees dialed in. I've thought about it and I have to agree with the consensus of anti-clockwise.

Now I don't want this to move, ever. So I'm thinking I will put some loctite on the nuts or something.

Sorry to keep replying to this thread But I'd never seen a picture of an Apexi cam wheel before mine arrived this morning. I thought some of you might be interested so I took 2 pics and attached them here.

When I was looking at buying one I found Apexi to be the cheapest, and because of that it made me wary. To be honest if the brand wasn't Apexi I would have gone for a more expensive one, it was just that I trusted the name and so I decided to go for it. After looking at it and feeling how solid it is and how precise the machining is, I'd say it's as good as any other in the quality stakes.

There are no doubt lighter/stronger ones available, but at a higher price. I'm happy with my choice.

its cool that thing confused the hell outa me to.

had many a sleepless night wondering weather i done it the right way or not. almost a question worthy of national iq test(he he he)

[otto]

that thing looks pretty good how much did u pick it up for?

[JimX]

11261 yen plus 2100 yen delivery = AU$175 at the exchange rate on the day (a few weeks ago).

The HKS one was the next one up on the price list at around 11800 yen I think.

[EnricoPalazzo]

can u post pics of how to install it pretty pls

I confused the crap out of myself !! LOL

I adjusted it correctly, then yesterday my brain got scrambled and I explained it wrong !

Thank god it's Friday....

Just a word of warning, make sure the adjustable bit is tight else your timing will slip badly and make the car backfire and run like a pig.

[JimX]

Already loctited.

[SeriesIIGTST]

was simply suggesting for anyone else

Glad you were on the ball, i almost wasn't when i put mine in.

[JimX]

Can someone tell me where the crank nut is? Does it need to be rotated with a socket or will a bigass shifter do?

[JimX]

Ok now I'm just depressed. The hardest thing so far is getting the wheel back on. How do yo do it? I tried putting the original one on but it's still bloody impossible. What can I use to lever it on and where do I lever it? There just doesn't seem to be any points where I can lever it from.

The cam seems pretty well fixed in place, if I can't rotate the crank with a socket (since I don't have a 27mm one) can I move the cam slightly? I've already marked where it was when I pulled the wheel off so I've got a reference point.

No rush in response, I'm going to leave it for the day. I need a break!

[Jay95R33]

JimX - if you can't rotate the crank, then rotate the cam a little - and I mean just a little.

You'll need to rotate the cam counter clockwise.

The other option is to set the cam gear to zero, put it on, then adjust it on the car. Not my prefered way of doing it, but I suppose that's the way they dyno tune them (eg. adjust them while their on the car.)

Well, the problem is I can't even get the original one back on The belt is just too tight. Can I somehow loosen the tensioner or something? Or just lever the wheel on somehow.

[Jay95R33]

Hmm, did you clamp off the belt to the inlet cam wheel??

I was thinking before, you might be able to get the crank to move back a little by just grabbing the air con and power steering belts and yanking them backward. Not sure if it'll work, but it's worth a try. It might give you just enough movement to get it on.

When you've been trying to get the wheel back on, how close is the dowl to the dowl hole on the cam wheel? Can you see where it's out?

It's strange cause I had no problems with the tension of the belt, the only problem I had (with both cars) is that the dowl wasn't lining up with the dowl hole on the cam wheel - hence why I said a slight rotation of the crank let me get the cam wheel on.

I can't think of anyway of levering it back on. But maybe if you slightly rotate the inlet cam wheel which will pull the belt tighter on the tensioner which in turn will give a little bit of slack on the exhaust side.

Then when the exhaust cam is back on, just make sure the marks still line up and then the tensioner will move the belt back to where it was before (cause the belt is toothed).

Give that a try and see how you go.
