How do you guys correct top cam lean?Â Holding the bow in shooting posistion, the top cam leans toward the left. Thanks for any help.The AVS uses a floating yoke, you can’t correct cam lean.
The real question is if the cam lean is enough to affect accuracy? If you can paper tune the bow and shoot tight groups, then the cam lean isn’t pertinent. If you can’t get the bow to tune or shoot good groups, then a dealer should determine the fix.
Laying a shaft against the shelf-side of the cam, if it doesn’t cross over the string before the nock point, accuracy usually isn’t affected.I placed an arrow like you said, and it crosses at the knock point close to 1/4 inch. The bottom cam is good. What is my next step? Thanks for your input.
Location: Call me...867-5309Take it back to your dealer.Â Sounds like warranty work.The end is near....Unfortunetly, I bought the bow used.Â Just need to know what to do to fix this. I kinda feel like this bow is a dud and dont want to resell and give the problem to someone else. Thanks again for any help.First, make sure you are shooting a properly spined arrow … the MR-series likes a slightly stiff arrow spine, stiffer than what most arrow mfgr charts say.
Second, can you tune for a bullet hole at 5′ and 10′? If so, you are OK.
If not, then you can take it to an authorized Mathews dealer, you’ll just have to pay for the labor to find out what the fix is, then you can decide if you want to sink more money into the bow by having it fixed.Ill give my specs. 27.5 draw length, 63 pounds draw, 27″ easton flatline 340 doa shooting 100 gr.Â Have a new trophy taker limb driven rest on the way. The lean just looks wrong at rest. I will try paper tuning at those yardages and report back. Thanks again.Arrow spine is good. See if you can get a paper tune.Will do. thanks again for you time. Icant imagine it will get bullets, but one can only hope.I took the bow to a shop and the guy said he can fix the cam lean by adding twists to the yoke on the avs. Does this seem right?The AVS system has a floating yoke that allows the bow to find its center of limb twist/torque. Unless you have a static yoke, like on the Mathews solocams, adding twists to the AVS yoke system only shortens the cable, it does not correct limb twist/torque.
I recently converted an old Browning bow from floating yoke to static yoke, and it worked out very well. However, my dealer tells me if I convert my Monster to a static yoke to tune the cam lean it will void the warranty.Thats what I thought. He was a young guy but I also talked to a more experienced tech. He said it would probably need new lims and or limb pockets. Seems this is pretty common with the monster and mr series. I really like the bow, and hope they get it figured out soon…i just got back from the dealer show and had a long talk with bob jenkins from mathews about the mr series cam lean issues. there have been big changes in the limb department, which is the single biggest factor in the lean issue with a floating yoke system. the limbs must be correctly matched to provide correct orientation of the cams. the major change is that now the limb blanksÂ are ground by a robotic arm to get the proper deflection which is computer checked. this process used to be done by hand, and wasn’t the best or most efficient way. bob actually showed me a video on his phone of the process, it was amazing. so,,, anyone finding that there is more than1/4″ crossover gap at the nok point when checked with a straight edge(arrow) should see dealer for a new limb set to cure the problem.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktechThanks for the info. Curious to see if my what my shop comes up with as I now know the limbs are bad. I am confident they will get it right.That also means they got the limbs right on the chillr. How about the chill or creed?
