Hi Everyone. My Onza top cam is touching the inside of the top limb. Have swopped the limbs but still the same thing. What can I do? Thinking of getting a set of Barnsdale limbs. Who has them and what do you think of them? Thanks!

I've got them on my Iron Mace and love 'em. But it sounds like you might be lacking a spacer on that side. Call Martin CS.

Thanks fro the reply. What spacers? The cams' bearings touches the limbs on either side. Is there a space for spacers in there?

Ok, please bare in mind that the limbs have been swopped, top limb is now at the bottom and bottom limb at the top. In the first picture you can see where the limb has been rubbed by the cam, circled in red.

In the second is the top cam, where the cam bearings are touching the limb on either side of the cam, circled in red. I dont see how spacers can fit in there? Are the spacers on the inside or do I have to shim them down??? The black insulation tape is to protect the limb from the cam, but the cam eat away at it after a few shots.

Any help will be greatly appreciated, Thank you.

Looking at it just looks like can lean at rest? Are the limbs split at all? My cheetah had slight cracks on the limbs and made mine almost do the same thing..... did u add a ccs or different slide to pull your cables more?

There shouldn't be any spacers with that bearing. It's designed to sit tight against the limb. It looks like either cam lean, a bad bearing, or a bent cam from the pic. Unless you find a crack or split in the limbs, I'd take a look at one of those 3 things. One other possibility is a bent axle, or wallowed out axle hole in the limb. I'd run some cotton all over the limbs, especially the forks, and check for a split or crack first. Then go from there. If you do end up replacing limbs, Barnsdale makes some mighty good ones. I have them on several bows.

Did you check the cam? its bend?

Check cam first, if its bend or tend, no point changing the limb.
Unless u are confirmed the limb is twisted and causes the cam eating the limb.

Adding shim or spacer i dont think i works.

Barndales limb - they are very very durable limb. you will Not gain speed.
They are famous for durable limb.
The limb is much slimmer then the Powertuff limb, and very precision and almost identical top and bottom.

"Which i do find out that Powertuff limb have soft and hard limb even it comes in a pair" - this is only my experience playing around with 2 pairs of powertuff limb, Or maybe i have no luck with Powertuff limb.
I found out this is when i do the tiller adjustment, where the top limb actually need to turn 2 advance round for best result, and worst combination of two limb with top limb need 4 turn to even the tiller adjustment.
U still can shoot good with that combination and with no harm. Just mental whether u like it or not.
I still get 2inch grouping with Powertuff or Barndales limb out to 30 yards.

i have two sets of Barndales, where the original from the bow is 135, the tiller only need a quarter turn on the top limb to even. and my another set 155 limb only need a half turn advance to tiller adjustment.

i still end up using Barndales.

Compare the draw, Barndales limb are more smooth in terms of the draw motion maybe because the design is slimmer. Powerstuff limb u actually feel the hump for the draw, where Barndales limb dont.

Not to say Powertuff is not good. But Powertuff is powerful and u will feel the different, coz the limb are design much thicker then Barndales.
Once u get Powertuff in tune, its also shoots very fine like Barndales limb.

My own experience is that Barndales give u a durable and precision design limb and smoother draw.

Thanks for all the input, it is great. The limbs does not have any cracks or splinters. They seem 100%. The cams are not bent and the axles and bearings seem fine. But I notice some cam lean. The bow had the TRG on it but it was replaced by a normal carbon rod and slide. How do I get rid of the cam lean??? The bottom cam seems the worst, but it is not hitting the limb anywhere.

So it seems that the cam lean may be the problem. How do I fix it? An please don't say a shoot through system:(

is your cable/slide routed on the right side or backwards.crosed up wrong.running out of ideas.

I agree, it sounds like your cable routing is messed up. Maybe you have left handed cams on a right handed bow or vise versa?

I replaced the TRG/SOS with a standard rod, and use a Saunders Hyperglide guide. I haven't had any problems with the bow at all (knock on wood) other than that I felt the TRG/SOS was loud...

New limbs? What will the deflection be on the 70# 5M limbs and Nitro 2.0 cams? (for Barnsdale limbs that is)

Have you tried to backout the limb bolts, press the bow, and remove the string and cables? Just see if everything is fine when there is not limb twist from the cable guard. If the cam is rubbing then you definitely have something wrong with the cam, bearing, or limb. Or better yet you could just take the cables out of the cable slide -- duh, me! If you aren't rubbing with lack of cable side tension then I would play around with a bent cable rod or a tilt tamer or a different cable slide that put the cables closer to the riser.

I've taken the bow apart when I swopped the limbs and everything seemed fine upon inspection. When I draw the bow, the cam never touches the limb at any time. It only happens when the bow is fired. The cams are fine and the bearings and axles are also in great shape. I am thinking of putting the Saunders slide back that it had on it and see if that helps.

Were you having problems before you swapped limbs?

Yes, that is why I swopped them to see if that won't solve the problem.

Any idea what they did to fix it?

Maybe the same as the Rytera bows w Barnesdales. I dont see why it wouldn't be.
