DRAW LENGTH ADJUSTMENT (INNER-CAM

ADJUSTABLE MODULES)

Many Hoyt bows utilize the inner-cam adjustable

module for draw length adjustment. The inner-cam

can generally be adjusted without the aid of a bow

press.

CAM & 1/2 DRAW LENGTH ADJUSTMENT

TOP CAM:

& 1/2 (inner-cam) model bows, use a standard allen

key to loosen the fastening screw and to remove the

draw length screw. Rotating the inner-cam

in the (+) direction will lengthen the draw. Rotating

the inner-cam in the (-) direction will shorten the

draw. Each lettered position will provide approximately l/2 inch longer/shorter draw than the previous setting. Once the innercam is in the desired location, reinstall and tighten the draw length screw first and then the fastening screw.

BOTTOM CAM:

Remove the draw length screw,

rotate module to the same lettered position as the top

module, and replace.

Note: You must

make the same adjustments to the top and the bottom

inner-cams or the bow will not tune properly.

WARNING:

N e v e r remove the s t a i n l e s s steel control cable peg unless the string is relaxed in a bow press.

What model Hoyt are you shooting?

its and old legacy super slam not sure what year i got it cheap hope i can use it if not i'll still use my old browning

I am pretty sure that model requires a new draw length module. I could be mistaken, though. Take it to your local pro shop and see what they say. If it needs a new module, that's not difficult, but not a do it yourself task either. I am pretty sure it will need a module.

that sounds fine i hope i can and i will call pro shop in the am any idea of a price for the parts

I wouldn't think any more than about 10 bucks.
