please read posts following this-

So, i called DC (FYI jut got bought by AEM), they were clueless about it, so, for some reason, instead of attempting to resolve it on their end...they transfer me to an AEM tech. I mention the fact it is a DC piece several times throughout the conversation. The tech did not want to absorb this bit of info, he is yelling at me about how "their" gears are correct, and I am wrong. Then, finally, he realized i was talking about a DC gear, and apologized. He said to send a picture in highlighting the error, and he would work something out, i assume with an AEM product since DC does not make cam gears anymore (i wonder why...jeez)

It looks OK to me, here's why...

The cam gear is made for 1.6L. This cam is set in head about 5-6 degrees advance. Actually, TDC for the cam is with the marks at 9 and 3 on the cam gear to be perpendicular with the top of the cylinder head. The cam key way will be off slightly from true 12 o'clock. This would automatically set that 5-6 degrees advance for the cam for a 1.6L

Trust me, the cam gear should be fine, just install and see for your self.

If you doubt me, try this...

Set the cam gear adjuster to 0 and install gear, then check ignition timing with timing light, if timing is drastically changed after install (ie. 8-12 degrees, then cam gear is wrong) but you shouldn't have any problems

 

However, I think you might be mistakenly looking at it wrong. If you intersect the 3 and 9 positions on the cam gear and then intersect the cam key, you will see what I mean about 5 degrees advanced, not retarded. When cam gear lined up with cylinder head, cam should be advanced 5 degrees or so.

But then again, if cam is seriously advanced clear to the 10-11 o'clock position, that is way too advanced. Unfortunately, I don't have any other cam gears here in the shop to compare your picture to.

Let me know what you find out though...

I'm very curious

 

Also, again, the cam itself should also set advanced in the head also. Not just the cam gear

unfortunately, this is the case with my cam and this cam gear.

 

You definitely have questions brewing here then...

Again, let me know, I'm curious...

 

ok guys...this is the definitive post...this is why i was confused when i installed the DC and what started me on this...

now..peep the errant DC TDC mark...almost 5 degs advanced from where it should be...and, when on the car, in combo with he forward head slant, they end up @ like 10:30!, but the side marks are equal to the stock y8 piece...

 

OKay okay okay. THe 96-00 Honda civics has an offset key way. You are using a cam gear specifically made for the 88-95 Civic motor. It is 5 degrees offset. If you look at the AEM cam gears there are two different part numbers for those years of vehicles because of the offset cam gears. 23-600 & 23-604.

stock Y8 gear- note keyway is offset from vertical axis, however, TDC mark and side marks form perfect cross. CORRECT for Y8


AEM Y8 gear- exact match to OE gear, CORRECT for Y8 (special thanks to OC_CIVIC for the gear)


DC Y8 gear- note, like the stock y8 gear, side marks are on-point and keyway is offset, BUT, note that TDC marks are 4 degs away from vertical axis of stock y8 gear, though sides match. INCORRECT for everything


AEM Z6 gear- note vertical axis bisects keyway CORRECT for Z6 (this is really a D16A1 gear, but, the marks are same as Z6)


Yet another erroneous gear. Golden Eagle piece for a y8, yet compare it to the Z6 gear up top, no difference!...no offset keyway, nothing...I can't explain this one...

Okay sorry about that wasn't really understanding what you were saying. I am going to look into why DC lasered there TDC mark in the center of the valley rather than the center of the peak. Sorry wasn't clear on that. The cam gear you have is correct for your vehicle however they did not laser the TDC marks in the peak of gear tooth. If you bolt on the cam gear and use the side marks as your indicators for aligning the cam gear to the head it will install correctly. However the cam timing marks are off, but it really doesn't matter where they are placed they will still do the same thing. There is no TDC reference on the cam gear from DC. Also the bottom gear you have there is for like a Integra not the civic, but the marks are in the correct spot for the Civic as a ref. The Golden Eagle cam gear I am not sure what is up with that.

He means the AEM one (tis for a d16a1); that is there solely for referencing how the marks for a Z6 look

RType, you are correct about the DC having NO true TDC mark, however every other manufactuer in the world puts one on their gear, in one way or another. Also, they are claiming it does within the 'structions, and, to be honest, I just want one that is like every other well-engineered cam gear....you are correct that the degree marks could be anywhere on the gear, however, due to them mismarking this thing and mysteriously shifting the 0 mark a few degrees, I had to set my lash by finding TDC old school (peeping rocekr assembly) and same thing with checking static timing becuase at the time all i knew was something was off w. that gear, jsut not exaclty what. That is not what I paid for.

never in my life did i spend so much time with a damn cam gear, so if thye admit the error and give me a normal gear, like everyother one onthe planet with an indicated TDC mark, i'll be happy!

 

I would give the warranty and claims department a call and talk to them again. Also they don't make the DC cam gears anymore so if they do replace it they may do it with a AEM gear not sure. Call them and see what they can do for you.

 

VICTORY!

email from Robert Green @ AEM/ DC-

Jehan @ DC Sports says that the gear is not correct (your point) and that
we have the correct ones on the shelf. Please send me your address so that I
can send out a new gear. I also need to give you an RGA# for the old one.
