Ok. You take your experience with one Mathews over a couple months. I’ll stick with my decade plus and thousand plus Mathews experience “bro”.

Ive seen asian women driving that have been driving for decades. Does that mean I want them to teach my son how to drive??????!!!!!!!!!!

Asian women can teach your son a lot, but I don't know that it will be driving skills.







Tho I bet he can earn the nickname smooth operator afterwards.

either way you overtorque it your gonna break it.


Since all this is centered around bearings, I feel its appropriate.


Can't wear nothing out that makes its own lube.


Engine builder told me that.




To the point, the bearings they are using aren't thrust bearings, so they can't handle it, but the best ones do come from Asia.

Well considering my wife is Asian. Drives stick. Tows, backs up, and parks a trailer better than most men. Yes absolutely. Anything other else?

Definitely can be attributed to user error, but I think we can all agree it’s not very inspiring to see something stamped made in China from a bow that was made in the USA just to save a few cents per bow.

At least go with Japanese bearings.

That being said mine came in yesterday and I went ahead and replaced them. The ones I pulled were crunchy as hell.

Shooting darts already this morning.

So is it easier to just order aftermarket replacement bearings or to go through the dealer? Would a dealer order the cams and allow you to swap them yourself or do you have to have the dealer do the work? I ask this as I have my own press and could swap the cams out, but if you have to get them through the dealer is there something Mathews has implemented saying the dealer has to swap them out for the customer?

That is likely a dealer by dealer thing. I'm certain the dealer is supposed to do it, just not all are going to insist they do it if you can handle it yourself.

I'm assuming you are talking about upgrading bearings but still keeping the warranty? I don't think dealers offer aftermarket bearings, just the Chinese Oem ones. Usually if a bearing fails I think they just replace the whole cam. Your dealer would probably say if you changed the bearings it's no longer in warranty, but depends on the relationship you have with your dealer.

If you are talking about upgrading bearings on your own without the dealer it's very easy if you have a press. just order the aftermarket ones in the YouTube video description. Put your bow in a press and pop the cam outta the axle, pop bearings outs with a punch, lube new ones, press them in and youre good to go. They look just like oems, just don't say China on them.if you are trying to keep the warranty and ever had an issue with them your dealer would probably never know if you did it on your own.

I have no preference either way, I guess my question is would the dealer I bought the bow from order cams w/ bearings or just the bearings and give them to me to do my own work or would they make me have them do the work.?

The cams come with bearings from mathews.
The dealers dont replace bearings.
If the bearings go out they just replace the entire cam.

Exactly right…it took me ~2 weeks to get my new cam from Mathews via my LBS.

They aren't going to upgrade the bearings. You just get a new cam with the same chinese bearings if going through a dealer. Kinda pointless. I'd order and replace yourself following the YouTube video. You just need some grease, a punch and rubber mallet and the bearings are like 20-30 bucks. I had some extra takeoff sw cams that I was able to do a trial run on. Surprisingly simple so I did it to my vertix as well when changing strings recently. These bearings look very similar to the OEM Chinese ones so if you replaced yourself and had an issue down the road the dealer wouldn't know any better if you needed warranty work.

digging up an old thread here, I know. Long time lurker, new member. Chasing some issues with my V3. 25 years of shooting and tuning bows. no real issues in the past that I can recall. My V3 though continues to give me nock low tears. I don't get them with my Triax. I've tried several different arrows. Lighter weight arrows are better than heavier ones with regards the severity of nock low tear. I've adjusted the draw weight between 56 and 66lbs with 4 different arrows and still the same problem. I've gone through all of the normal tuning issues. Nock pinch, level arrow, cam timing. All of it. Everything has been checked and triple checked, and checked again. I'm down to believing it is either a tight cam bearing or weak limb. I'm leaning more heavily towards the cam bearing.

With regards to the problem discussed here, what was the original issue with the bow that caused the OP to consider the bearing?

Old thread but giving it a bump to see if anyone successfully and happily replaced their bearings, how the higher quality ones are holding up, and what specific ones they bought. Looking to do the swap as well. Thanks!

I changed mine out using Koyo’s. Originals were still okay. Nothing noted so far after several months on the new ones.
