Today I was climbing with a few partners and one happened to take a big fall on a .4 Camalot of mine. One of the inside cam lobes is now bent cosiderably, enough to stick while in the camming motion. SHould I contact Black Diamond? Should I return it?

Sounds like you need to toss it or downgrade it to Toprope only status to me.

Maybe if you posted a picture a better diagnosis could be presented. Sometimes the lobes just stick a bit and can be freed by pushing them around on the axle. It is possible though that it might be too worked. Ultimately its your call though.

Doesn't "Bent" mean not straight? Doesn't "Considerably" means not an insignifigant amount, as in a lot. I don't think they are oiling it to make it work. My thoughts. It sounds like it was put beyond the limits and is now broken. Trash or a discussion piece.

pretty sure you have to have a link to your pics, machino. do you have a photosite to put it up on? You can do it here, but if you want, send it to me, too, and I can put it up. hussefelt @ hotmail.com Brent

that was really constructive. If you feel like it was a manufactuer's problem that caused the cam lobe to bend, contact black diamond and they'll replace it. But if he took a whipper on static cord or something stupid like that, you're SOL. I guess it couldn't hurt to contact them anyway.. but i wouldn't lead on that cam if i were you.

OK, I don't have one in front of me, but a .4 Camalot is pretty small. The lobes are fairly thick. I would have a hard time imagining that 6000 series Al with an aspect ratio of (guessing) 2:1 would bend. More likely if anything bent it was the axle. Once again, get a picture up here.

Hello there, I am a friend of machino's and was there when the cam lobe was bent. Allow me to try to clarify the situation. If you look at the top of the cam lobes (ie with the stem facing directly away from you) you can see that not all of the lobes are in the right places. One of the internal lobes is angled differently than the others. Essentially it looks like this: l l \ l with each slash being a cam lobe.

Sounds like you placed the cam in such a way that loaded the lobe sideways and now the axle hole is out-of-round. If it's so bad that the cam sticks, I would not use the cam. It's a keychain or christmas tree ornament now. Go buy yourself a new cam.

http://www.tinypic.com/view/?pic=s4chut There is the pic. I just wanted some advice on what I should do with it as I like to be safe. As you can see it isnt bent much but it is enough for me to be worried about. Anybody have a constructive resposnse other than the computer climbers who know how to host picks really well. wankers

http://tinypic.com/s4chut.jpg are you talking about me and the hosting pics? I think the cam is shit, and you should replace it. Why not? 50 bucks, you get something you KNOW is safe and you don't have to worry/risk another thing. Brent

I'd say it's pretty clear you have a bent axle there - take it back to where you bought or send it to BD. They don't use the burliest axle design so that doesn't necessarily surprise me all that much...

You didn't bend the lobe at all. You overloaded, torqued and bent the cam axles. Had this not been a BD with twin axles, it's likely that the damage would have been much worse, and POSSIBLY even resulted in a complete failure. I have diagrammed your image, to show where the bends are. http://www.great-river.com/pix/bdcam.jpg

No way to overload a cam without any deformity to the lobes. That just shows minor scratches. Send it to BD.

In reply to: While we're on the subject, what's the verdict on this cam? The trigger pulls cleanly without any binding. errrr - pooched ? just a guess - lools like the inner lobes took some force at some point ? not sure I would lead past that unless i was aiding on it... do *you* trust it ? the real question....maybe show us the same angle tgreene diagrammed above ? (sweet work btw t...)

I don't know man, the cam is rotated slightly clockwise in the picture and your diagramming doesn't really convince me. It looks like the cam foot is just shifted a bit but the axle is still straight. I would take a straight edge and check if it were my cam. Either way, if you are sketched replace it... $50 isn't worth the risk. And that #2 was obviously fully open when it was loaded, as indicated by the big ol' gnar gnar on the inner right cam lobe. That puts way more torque on the lobe. The last picture shows that the outer 1/2" or so of the lobe is obviously bent. I would replace that one without question... or sell it on ebay.
