Does anybody know how many degrees each mark represents? There are +/- 7 marks.

The skunk 2 site says that they're supposed to be +/-10 degrees of adjustment, but that would be a complete design idiocy.

 

how frustrating?!

it is as simple as counting the teeth, really. there are 360 degrees in a circle, and
35 teeth on the B series cam cog. this allows for each tooth making 10.28
degrees per tooth at a fixed rate. with this adjustable gear, each "mark" would
then represent 2.056 degrees in cam/crank refrence. whats weird is that I have
a set of skunk2 gears... and they go +5/-5 and I just realized your dilemma. if
I were you since it is kinda hard to do it form this angle... take a straight edge...
take the radius of that last line and run it through the center of the gear. see where
it radiates out to the teeth. from centerline to centerline on the cog, there is 10.28 degrees. if you broke that into mm from centerline to centerline after you determine which line radiates to the center of the tooth, then you would know how many degrees each line is.

My estimation is that the +5/-5 marks will radiate to the centerline and +7 /-7 is only to the middle between the next tooth. why they would want to do this>?
I am not sure. All I know is I have a set and they only have +5/-5 range and those marks' radiate to the centerline of the tooth just before and after the TDC reference which is a range of 20.58 degrees. hope that helps.

That would work, but I think I'd run into a little bit of error b/c of either weird camera angle(s) or subjective eyeballing if I were to do it directly on the cam gear.

I even thought about tracing the gear teeth on a piece of paper and doing some simple geometry and using a little bit of logic to figure out the absolute and true 0 degrees for the cam gears and what each marking is equivalent to in degrees.

I decided on using a degree wheel on the crankshaft, putting pointers on the cam gear marks and the degree wheel, rotating the crank from one mark to the next, and then seeing how many marks the cam gears move by dividing the difference in readings on the degree wheel by 2.

Hopefully, 2 crank degrees will be equivalent to 1 cam degree of rotation.

 

Each mark is supposed to represent 2° of cam timing.

 

I'd rather not leave that to assumption tho, especially when I've got a cam gear that seems to be an exception to the norm.

 

it is an exeption. I would look at the final line, line it up to the inner most point of the circle and see where that mark radiates out. if at +7, it radiates out to almost in the middle of the second tooth, then you are dealing with 2 deg per mark. how do I know? read the above post. each tooth on the gear's centerline to the next represents 10.28 cam/crankshaft refrenced degrees.

 

yeah, that was another check i was gonna do.

foh-got to thank you.

thanks

 

no worries man

 

That's not an assumption. If they're Skunk2 gears, each mark is 2°. I doubt that Skunk2 would make all of their sets of gears the same except for yours.

 

If I took your word for it, then it would be an assumption.

And, yes...each mark was 2 degrees.

I also discovered that the gears only rotate to as far as just a little past the 6th mark.

 

Why ask the question when you weren't going to be happy with the factual answer unless you found it yourself?

 

Maybe I like being reassured that I'm taking the right path towards finding the right answers.

And, like anybody else, emotional factors of frustration and confusion got the best of me and were the initial motivational factor for asking in the first place, so I looked to the best support I knew available to me. After calmly reasoning it out with somebody, I found the answer for myself in the most practical manner available to me.

Sorry if I'm rubbing you the wrong way by being confrontational. Seems to be a trend lately b/c everybody seems to be on my case for helping them out and I'm just a little irritable b/c a friend of mine seems to be having a selfish streak.

My apologies again for something I normally would have ignored.


Read on if you dare....
The whole attitude thing spurned from me helping a friend lower his Gen3 Eclipse, and I told him I'd help, but wouldn't do the whole thing for him. After starting the job I found myself doing 90% of the work and him sitting on his fat *** joking around with other friends. He continues to do this off and on over the next 5 to 6 hours it took to do the job, even after I repeatedly ask and tell him to help. On top of it all, he has the nerve to get pissed at me for not having the torque specs for the suspension on hand. All of this when I had a stomach ache and was supposed to be working on dropping my engine into the car that night instead of doing his car. Shoulda packed up my tools and just left his car in pieces.

 

It's one thing to let someone take advantage of you as this dickbag did, but it's another to take your frustrations, from said dickbag, out on someone who had nothing to do with that situation, and is trying to help you in your current one. But what's done is done - you need not apologize. Next time, I'll know better.

 

2 degrees per mark

 

you shoulda just got half done and left so his fat *** could finnish....

 

on my test drive from my h22 in accord swap i snapped my cam gear
damm flaws. i ll just go order another

 

snapped a cam gear?
