Swapping the Mods on the Crosscentric Cam (MXR)

The award winning Crosscentric cam system on the new MXR runs off a modular system for draw length adjustment. This means the draw length can be easily adjusted by removing one module and replacing it with another. Each mod is assigned a draw length for precise adjustment without the use of a bow press. 

There are three screws located on the mod. Two of these screws ensure the mod stays secured to the cam (Figure 1), while the third is threaded through the felt wrapped draw stop at the very tip of the mod (figure 2). This draw stop is the part of the mod that comes in contact with the string when at full draw. To remove the module, the draw stop must be removed first. Simply loosen the screw with a (some sized) allen wrench and set aside. This will need to be reattached to the new module after it is replaced. 

Next, loosen the two screws that hold the module to the side of the cam. After these are removed, the mod can be slid rearward and taken off of the cam. To install the new mods, these steps must be repeated in reverse. First, slide the new module into place. The markings on the side of the mod should face outward. Carefully press the mod into place until the holes in the cam align with the holes that go through the module. Insert the screws back into those holes and tighten until snug. Do not over-tighten. 

The final step is to reattach the draw stop to the tip of the mod. Thread the screw that is attached to the draw stop into the hole at the tip of the mod and tighten until snug. Do not over-tighten. Once the new mod is fully attached, you’re ready to start shooting.
