Ok..... I am sure that this question has been asked a million times,but I couldn't find a answer. Any way I have a Hoyt Razor TEC bow. I have used the BOW PLANE to check cam lean and center shot. Any way I noticed that I have some lean on the bottom cam. What can I do to fix this problem if anything? Thanks for all of your help!!

With most bows you just need to put a few twists in the cable yoke, usually the right one for a right handed bow. On single cam bows there is only one and it's at the idler wheel. I'm not sure about Hoyt having one or two, but in any case they have a floating yoke, meaning it's not served tight nor is it a static yoke.If you twist up one side of the yoke it will self-center itself on the first shot or two. The only way I'm aware of to change this is to served the yoke very tightly where the yoke attaches to the cable or replace the cables with ones with a static yoke (meaning a one piece cable). Then you can twist to your heart's desire.

There's nothing you can do about it on the bottom cam of a cam 1/2 rig except to get a cable slide that pulls the cable off to the side less but then you may run into issues with fletching clearance. A little cam lean is "normal" and can still yield a tuneable bow, it's when it gets excessive (maybe 3/8 or 1/2 " string deflection at the rest) that it becomes a real problem. I never have been able to get a straight answer from any company rep. about how much lean is too much. They all give you the line that "it's designed in" but they won't say how much is designed in. I have had them admit that if the cam rubs the inside of the limb that it's excessive, but that's about it.

Kodiak,

Someone who tells you if the "cam rubs the limb is too much" is feeding you a line. What we archers refer to as cam-lean has little or nothing to do with the cam alignment. In reality it's limb twist caused by the cable slide/rod. That's why we can correct it by twisting one side the cable yoke. In most cases, if you remove the cables from the cable slide and check fo cam-lean there will be none. Of course this assumes everything has been machined correctly and assembled well, too. That's why the Martin shoot through cabling system removed all cm-lean. There is NO cable guard and slide.

Just one thing I'd like to mention. ANY cam lean is not normal. There is nothing normal about parts not aligning right on a bow. A word I like to use is COMMON. Yes, it's common on most cable guarded bows, but it sure isn't normal. It could probably be engineered out, but so long as we consumers are mostly worried about speed the companies are not going to address this problem.

Hoyt bows yoke is at the top BG and does float or supposed to. If the cable is twisted to tight it can bind on the yoke.My bow sets up best out of spec and long. Set in spec it's to tight and does cause a lean.

There aint much of anything pulling the bottom cam on a hoyt to the side. I think it'sa mechanical thing. Or, a mechanic thing.

Ya'll know more about this, and I'm enjoying reading this. I'm just going to relay a recent experience.

My bow was shooting awesome. Beautiful arrow flight, the whole enchilada. Then one day I noticed my arrow "wiggling" a little in flight. Assuming I was doing something different, I didn't pay much attention to it. 4 days later the wiggle was still there, and worse. OK, time to look into this. Centershot was still good, arrow was still level......There was nothing visible that I could see causing it.

Off to the shop for some paper tuning. First shot yielded a 3" right tear. No lie. I'm scratching my head......Huh?? I tried adjusting my draw weight, different point weights.....Checked arrow straightness (i'm shooting aluminum).....nothing made any difference. So, I moved my rest to the right......no better. The only way I could get a good tear was to move the rest WAY to the left, opposite of what I should have done. Finally got a good tear, but.....I was SOOOOO far out of center there's no way I'm shooting this way. So I put it back in center, 3" right tear again.

TOTALLY frustrating. I kept going back to cam lean, but I couldn't see any. Figuring at this point I had nothing to lose, I twisted the yoke (the right side, as I'm holding the bow)....Got a little better, so I put 3 more in it. Perfect. Beautiful arrow flight again. Bullet hole in paper....I'm a happy guy.

The moral of the story is.....ANY cam lean isn't good. That string has to travel square or it's going to push the nock end of the arrow one way or the other. Unless I'm thinking wrong, which is certainly possible, there had to be some cam lean there that I just couldn't see.

Problem is that with a binary cam system there is no yoke to twist and the cam was rubbing the inside of the limb. They were feeding me a line that cam lean is designed into the binary cam until I told them about the cam rubbing. Then they back tracked and admitted there was a problem. The culprit was mis-drilled axle holes on both the upper and lower limb. Solution: new limbs, which BowTech made every excuse not to send, and still hasn't.

Geez. That ain't no good. Hw long have you been dealing with them on that ? Were they drilled crooked, or just to much slop to cause the axles to float around in the hole ?

I reread my post and see I forget to mention about the crooked axle holes which you just did mention. In my experiece the only way a cam can rub the inside of the limb fork is if the axle holes were drilled crooked or the cam was machined wrong and the bearing is crooked.

Some people sometimes mention about the bearing being worn out, but I've never really seen a bearing wear out. They are precision insruments and in a bow are not subjected to any high speed movement so it's not going to just wear out. Bushings? Yeah, they did wear out, but for the most part this is bygone technology---at least on quality bows today.

I do know what you are saying about no yoke on a binary cam system. I shoot a Martin FireCat with binaries. Yes, if there is any cam lean you're stuck with it. That's one reason I always advise people looking at new bows to look things over real good, shoot the bow, and if everything is up to snuff then buy that particular bow, not something they haven't laid eyes on.

Hope somehow you get your bow fixed. I had a Pearson like that once and it sucked. They were good enough to send me new limbs though. Maybe that's what customer service is all about.

Thanks everybody! I guess I will start with servinv my cable into my floating yoke and then try a twis or two. If that doesn't help I will just either live with it or see about new limbs. I hope it is nothing that I can't fix. I really like the bow but i do have a problem with arrow flight, not much, but I am really picky about things like that.
