I'm getting some warranty work done on the bow again in reference to the draw module being sheered off again this year which I posted about the other day. The string comes off pretty harsh to the right if your holding the bow in the shoot postion which I would think puts a great amount of pressure on the cam and module. I noticed the big spacer on the cam axle was on the right side of the cam while the two thin washers were on the left. I would think if that were reversed it would lessen the angle of the string veering off to the right so much and still keep everything else in place pretty good looks like. This bow did have work done on it last year because of this same problem, so I don't know if the spacer was put on the correct side or not. Does anyone know what side the thick spacer should go on that cam axle or would it be ok to try it on that left side? Thanks for any input everyone.

i would think it should have spacers on both sides,and if need be a thin nylon washer on both sides too.can you post pics if you have not allready.i would assume that you have some major cam lean to be causing your problem.i just looked and my bengal and i have no spacers.what cam is on that cheeta,i have the acu-trac.so if it has the acu trac it should not have spacers on the bottom cam.

It's at the shop right now getting repaired so pics will have to wait a few days. But yes it did have the thin nylon washer on the left side but the right side was a thick black plastic spacer/washer. and yes it is the accu-trak cam. It appears to me the large black spacer isn't helping the lean at all! it looks like if the thin washer was on the right side and the other washer on the left it would help ease the string angle some. I'm not sure if it was like that originally or if they got crossed last time it was worked on.

The washers don't have anything to do with the lean. The yoke needs to be shortened on the left or lengthened on the right. This is done by twisting/untwisting the yoke ends.

yes MLN is corect.i had a theory i was working on but i got the answer to my question on what i thought might have been an issue,so now i will say with confidence it is your yoke that needs some twists added or removed to corest your cam lean which no doubt is causeing your problems.befor you walk out the door with your bow after it has ben repaired ask the guy to messure ATA(axle to axle),BH(brace height),make sure your cam is not over or under time,have him check it at full draw and relax,shoot it and if all is good then it should be good.i dont know if you have the specs for your bow buy here is a link.http://www.martinarchery.com/2011/2010_older_specs.php

print out the specs or write them down and make sure it is within spec.i had a shop try and tell me a half inch short is good to go,that was not going to happen with me.i made them put it in specs then found this forum so i do the work on my bow.not a shop.

Actually guys you can adjust lean by changing the spacers, its just not as easy to do as twisting up the yoke and you don't have the same amount of control.

Thanks for the help guys and I will definately recheck the specs and make sure they are on. I misspoke when I mentioned the extreme lean to the right, my cam is NOT leaning, it is straight. The cables come off straight but the string comes off the cam hard to the right. When the bow was in working order the cam is set closer to the left limb, if the washers around the cam were to just swap sides the cam would sit closer to the right limb thereby decreasing the angle the string is coming off the cam? Thanks again for everyones help.

Its a trial and error situation, not sure how it will work out doing that. Normally I can change the spacers by adding or subtracting different sized washers but a flat out swap around? I can't say for sure.

Be sure to measure axle to axle on BOTH sides of the bow. That'll tell you about how much you need to twist one side of the yoke. Shorten the long side if the other ATA is right.

NO! :p

I just put a few (estimated) twists and see, never tried measuring. How close does measuring get it?

Well..... being a fellow Cheetah owner, I understand what you are going through... I realize that you have ZERO idler lean, but the strings go to the right at the rest position, and can cause some severe string wear. The REASON for this is you have a Cheetah... The bow is just 30" ata... which causes it to be a shorter distance to your cable slide, which causes a more extreme angle at which the cables are pulled to the side. Changing out cable slides makes it worse, if they are designed for more vane clearance, and twisting your y cable is not a solution. What I did to help the problem was to smooth out the idler wheel as good as I could with super super fine sandpaper. After several shoots, your string will wear it down alot as well, but not until the factory string is frayed to hell. The factory string is cheap, SUPER CHEAP, and it sucks. If you look at the new Martin bows with accutrak, all of the ones I have seen come served with clear serving all the way around that top idler, just to keep the wear down. SOOOO the way I fixed mine was got new vapor trail strings, served all the way around the idler, and I make sure the string is waxed well along the idler... haven't had any issues since I have made that change..... hope this helps
