Hello friends, new here and hope to hang out here some, get to know some of you. Having some problems with my new M-Pro Cams just installed and hoping to get some insight. Please forgive the lengthy post but the information was neccessary.
There is something definitely not right with my Jaguar bow that has just came back from Martin, repairing a defective Dynacam and installing new M-Pro Cam, limbs & strings. Now that I have it back, this bow is just not usable, it is full draw weight not hitting the let-off right up until I hit the wall. Been shooting all my life, and was used to a Darton Thunder-flite for many years, it having a very nice smooth round cam action. So itís not just that I went from a radical cam to a round cam. There is no smooth let-off, much less a noticeable let-off. It breaks right at the point I hit the back wall on the string, leaving me NO valley. After researching everything I could possibly find I have come to this conclusion.
After researching many bows and manuals I have only been able to find a cam & idler wheel similar to the ones installed on my bow on the 08í Leopard, all other bows seem to have a different looking M-Pro Cam and larger Idler Wheel. Out of the 08í bows the Saber & Bengal seem to be most similar in size to my Jaguar, both having the different looking M-Pro cam & larger idler wheel. The leopard is supposed to have the Mini M-Pro since it is a lighter duty bow, so not sure if my cam is a M-Pro or a Mini M-Pro? Was my version of the lynx light duty as well, to where it should take the lighter duty cams?
Pics of the M-Pro cam in all year manuals appear to be positioned different than my new bow setup. The hole in the cam where the string wraps around then hooks to the tab on the cam is almost parallel to the axle, where as my bow is approximately 1 ľ inches closer to the limb.
I also read a thread in here about the M-Pro timing. When I look down into where the string meets the cam, there is no sign of any groove showing.
ďwith the 08 mpro cam you need to have aprox. 3/8 to 1/2" of groove showing under the string to have it set to where it is most efficient. ď
I was also informed that I should be able to replace the modules without a press, yet the screws to the modules sit in between my limb not allowing me to remove the screws or module.
These facts and the technical info below lead me to believe my bow needs a different length of strings or possibly another cam setup. All I know is this bow is nothing like it was before I sent it in to be repaired. I have the bow at itís lowest possible setting and still doubt I will be able to shoot it in itís present condition, and opening day is here.
Comparing Axle & string lengths below things just do not add up. With the same cam, the only thing that should change the lengths is the differences in the A-A, so if my A-A is 1 Ĺ inches longer, my string and cable should also be 1 Ĺ inches longer. These numbers below just donít add up and my guess is I have the wrong length string, cable or both.
Saber & Bengal= A-A/32, String/88.5, Cable/33.5
Leopard= A-A/30, String/79.5, Cable/31.5
My Jaguar= A-A/32.5, String/86.5, Cable/33.5
This new cam setup had to fit a bow and these numbers just donít add up in any configuration. There should be some consistancy. Looking for some help here. Bow season is here and I have no bow to shoot. Thanks in advance.
