Got pics.

 

Are the brackets on the limbs on backwards.

 

It sounds like you have the Cams switched. This is what the Cams should look like. Picture is of the Right Hand Limb looking down at the bow. Joe

Make the pictures smaller and it should work.Not the file size but the actual picture size like 600x800.Hope this helps.

Joe.
I know you already know this but the cams are the same.
It just depends which hole you press the brass bushing in.

Tacmac,You may have to resize your pics to post them.
They would help alot.
I have some pics also of the front end of the bow after I upgraded mine
Heres the link.

Sorry guys... I just can't get any pics on this site. I resized down but I just keep getting an error saying wrong format or just gives msg saving post and doesn't. I'm gonna switch the cams and see what happens. Hope it works. tks for the feedback. tim

 

That was my bow that had the cams on wrong. The bushing was in the hole indicated in this image and I was not able to cock the bow. And just to be clear, this picture shows the correct installation. The arrow is pointing to the hole that should NOT be used.

 

Do you have a pic of the bottom? This looks like my set up now that I can't cock. The cable on bottom changes when I tried to change cams but the string was not right at all and too loose. Maybe this is the trick and will try it next. I just can't get my pics on this site. tks for the feedback on the bushings and that will be the next attempt. tim

 

Hey guys… I tried to change the cams around and the bow string was way too slack. Does anyone have a pic of the bottom showing the cam and cable? When I switched the cams the cable seems better tension so maybe I have this arrangement wrong on the bottom? Also gonna try to switch the bushing in different holes. Gonna try to post these pics again. tim

 

The routing in the pics you posted above of the right cam is correct.
If the left side looks the same then dont change a thing.
It is 150 draw weight and may take some effort to cock.
Post a front and back of the other cam and a picture of front and back of the whole front end so i can see it.
Cant find my camera at the moment to show you a pic but it looks like your routing

 

Heres some pics of mine.
Hope these help.

 

The Pics that "the hammer" sent are same as my set up... sure is frustrating. Understand the draw is 150 lbs but I have been hunting with this crossbow for 15 years and the draw is allot tighter after this icad upgrade and I'm only pulling half the way back... feels like the limbs are gonna snap?

The other post said to change the bushings? might try this now. do they just push out? tim

Pics of the bow now with upgrade.

 

I had the exact same problem when I changed my super sport over. Hit a wall about half way and would have broken limbs if I went further. My solution was to switch cams around to the other limb. Everything is great now and it's shooting as good as a new one. I also have a unaltered hunter supreme if you want to start from the beginning. Hope this helps.

 

The left and right cams are exactly the same. It just depends which hole you press the brass bushing in that will determine if they go on the right or left side.
The brass bushings are pressed in.
If you switch the bushings to the other hole you will also have to switch the cams around(left to right -right to left)which will put you back to what you have now..
Before the upgrade, with my old teardrop system my axle to axle was 21.780".
After I installed the icad system my axle to axle is now 1/4" longer at 22.062". This results in a lower brace height,a little longer power stroke and the cams are retarded back some compared to the old teardrop system.
Mine was also harder to draw back after the upgrade.This is because the cam timing is a little retarded(late) and are rolling over a little later while cocking than they were with the original string and cables.
If your setup looks mine then everything is correct. My bow also draws a little harder but also shoots a little faster.
I also have another hunter supreme without the upgrade and it does draw easier then the upgraded one.
I will try to post pics of both together to show the difference in the cam timing when I get a chance.
After you shoot it a couple times, check your cam timing cocked and uncocked and correct it by twisting the steel cables.
Twist the end of the cable that has the fitting that goes on the axle not the end with the ball.
I had to go 1/2 twist tighter on one of my cables to get the cam timing perfect.
If you have to go more than a half twist tighter on one cable I would untwist the other cable 1/2 turn.
Try not to twist or untwist the cables more than 1 turn from where they originally were.
If you can post some pics of left side, right side and the whole front end like I did so I can see.
I am also in Ohio in medina county. If your close and would like,bring the bow by. I have a press and can get it straightened out for you .
Hope this helps.

Hammer

 

Hammer... tks for your detailed feedback. Concur about the changing of the cam bushings... just be back to square one. I'm only over in Sandusky area and might take you up on offer to stop by and check out my crossbow to get it back in working order if your still interested? Would like to compare the pull and adjust the cam. tim

 

Wont let me post pics again hold on

 

Have you tried pulling harder.

My axle to axle uncocked is 22 1/16 . Its 19 9/16s cocked.

Have someone measure a.t.a. while you try to cock it, if it gets under the above number stop.

What your pics show are correct .

If you could post pics of the top and bottom of the whole limb assembly would still help.

I posted some pics of original teardrop and icad for you to see.

Yellow serving pic is the original setup

As you can see by the straight edge,The cams on the icad setup are retarded back further, So what this means is that your cams arent going to roll over until the bow is drawn further back from the original setup. This is why its harder to draw.

Trying to save you a 1 hour trip.

 

Tacmac.
Did you figure it out?

 

Hammer.... I pulled it back and it worked! Like you said... just a bit harder to pull at beginning until breaks down. Test shot was dead on at 20 yds. Only thing is the serving is not centered, not sure if way to adjust this?

Tks for all your help. The pics and advice were excellent and I was able to go hunting last week with the crossbow! This forum is a great way to get help. take care and happy new year. tim

 

If the serving is centered with the bow uncocked but off center cocked then the cam timing may need adjusted.

If the cam timing looks good both cocked and uncocked then the string just maybe served off center which wont hurt anything.

Pics of both cams cocked and uncocked will help.
