Admittedly, I am a newbie when it comes to strings and cables!

I had a Hoyt Cybertec stashed in an archery case for several years. I recently opened the case to find that the control cable had parted. I ordered new strings and cables and proceeded to install them, but am unable to achieve the alignment of the dual track idler the manual requires. The new string and buss cable were marginally shorter than the old ones, but I ascribe that to stretch of these old cables.

Since the control cable had let go, the string had disengaged itself. Now I wonder if I have the cables and string properly installed, and if so, why I can't get the idler indicators in the right position. I could really use some expert help in diagnosing the problem!

I'm second-guessing myself now. Since the string and cables were in disarray when I took the bow from the case, I am beginning to wonder if I have the buss and control cables reversed on the cam. I have not been able to find a good photo or diagram anywhere on the web.

Can any of you experienced folks help? I'd especially appreciate guidance regarding the arrangement of buss and control cable attachment on the cam.

As you may be able to see on the idler photos, the idler indicator is bracketing the limb rather than the buss yoke as the manual stipulates. So the idler needs nearly 30 degrees of further rotation, and so does the cam.

You have the Hoyt Redline single cam system. The rigging is incorrect for a single cam bow.

You have no control cable on a single cam bow.
You have a buss cable also called YOKE cable, cuz there are two yoke legs that attach to the top axle...this is the Y shaped cable.

You have a super long single cam bowstring. Your bowstring starts at the cam on the bottom axle, and runs all the way to the metal thingy on the top axle (IDLER wheel) and that super long single cam string runs all the way back down to the cam on the bottom axle.

So your bowstring is SUPER long because it is a single cam bowstring,
and your bowstring should be 93.5 inches long.

The Buss cable (yoke cable, shaped like a Y) should be 41.5 inches long.

Your bowstring is routed incorrectly.



Follow the YELLOW line to route your bowstring correctly.
With the riser on your right,
BOTH ends of the single cam bowstring, need to run around the cam in the COUNTER_clockwise direction.

With the riser on your LEFT,
both ends of the single cam bowstring, must run around the cam on the bottom axle, in the CLOCKWISE direction.

On the label on the limb, the string is clearly specced at 59.5". Not long enough for that double trip. The cables are specced at 38.5 (buss) and 44"(control). So the bowstring takes almost a full wrap around the idler. The control cable takes a partial wrap around the idler on the other side. The new bowstring and the new buss cables compare well with the old intact ones. What I am wondering is if I have the buss and the control cables switched on the cam. I can't find anything definitive on line.

Just found on this site that what I have is the Excel Cam. Cable routing is clear here.... Clearly, my cable routing is incorrect!

I just need to figure out which is the buss cable and which is the control.

SUCCESS! Since it was the control cable that parted, I had no clue as to its routing. I had inadvertently routed it around the appropriate cam lobe backwards. Getting that straightened out has everything looking good once more!

Thanks for your help!

First picture was SILVER cam and ROUND idler wheel up top.

THIS photo is a black cam, so you posted different photos.

For a hybrid cam, which is a buss cable and control cable,
on the bottom cam, the control cable runs around the bottom cam in the same direction as the bowstring.

Yeah, I recognized that the photo of the black cam matched my cam - an "Excel" cam (per Hoyt). From the photo, I was able to deduce that I had wrapped the control cable around the cam lobe the wrong direction. Once I wrapped it correctly, everything behaved properly.

Thanks for your help!
