basstrials Posted August 15 Report Share Posted August 15 (edited) Hi there,i have this problem with my echo freewheel.So,when i push down with my left foot it starting some noise, something like bearings inside the freewheel itself.It lasting from left crank arm horizontal to the very bottom then disappearing and appear this time in the right crank arm but for the tiny time but only when i push down with my right foot and then disappearing again and this not in every rev.Sometimes two times in a row,sometimes one time.It not skipping or cracking,just this.What this might be?If i need new freewheel what brand would be because Echo is out of stock everywhere.Thank you very much.

AdamR28 Posted August 15 Report Share Posted August 15 Sounds more like a BB / crank / pedal noise if it is more noticeable on one side. Quote Link to comment Share on other sites More sharing options...
basstrials Posted August 15 Author Report Share Posted August 15 Thank you,i guess it is has to be disassembled whole drivetrain to check all parts out? Quote Link to comment Share on other sites More sharing options...
basstrials Posted August 18 Author Report Share Posted August 18 I am pretty sure this is comes out from the freewheel.Any suggestion for new one?Would SL one could be put on my Echo( not SL one) or Jitsie? Quote Link to comment Share on other sites More sharing options...
Szymon Posted August 19 Report Share Posted August 19 (edited) You should have your freewheel serviced every six months. If you want it to work well and for a long time. Maybe sand got inside and that's where the sounds come from. https://www.youtube.com/watch?v=fe-KR5HHVgI PS Also check the chain to see if it is dirty or worn. He makes sounds like that too.

basstrials Posted August 19 Author Report Share Posted August 19 (edited) Thank you for your suggestions.The chain is clean and is one month old.I did buy this bike second hand and do not know how it is been maintained.The noises are like "overclicked"a bit if that is makes any sense but not constantly,just few of clicks more than usual and freewheel it is not so loud (it is sounds dull). Hundred percent is for service and maybe need new one.If it is need new one what choice do i have? Echo it is not longer made unfortunately. Thank you.

La Bourde Posted August 19 Report Share Posted August 19 I prefer freewheels using industrial ball bearings like the hashtagg. https://shop.hashta.gg/collections/roues-libres-freewheels/products/roue-libre-hashtagg-hashfree-12018 1 Quote Link to comment Share on other sites More sharing options...
Daan Posted August 19 Report Share Posted August 19 You can take the Echo freewheel apart pretty easily to inspect it. Just be sure to catch all the balls that will fall out, so best do it inside a cardboard box. Clean everything with something like WD 40, and reassemble. The ball bearings are a pain to all get into place, combined with the little springs, all just pretty terrible. Use grease (thin grease, otherwise you might run into engagement troubles) to sort of stick them to the bearing race, and be very patient. It's doable, took me a while though, and some proper swearing too haha. There's also a video on YouTube about this, guy is using pieces of string, but I did it slightly differently without.

basstrials Posted August 20 Author Report Share Posted August 20 Well,so i did.Take the freewheel out to check it out and it was in not great condition.The previous owner had done damage on inner plate of the freewheel trying to unscrew using wrong tool.The freewheel itself has a little play backwards wich it to is not good sign,so i did put i back and i am going to ride it this way until new one comes(i ordered one).I did find brand new SL as for the the present one maybe i would do overhaul after a time.Does new one need bed in time and how it is been achieved?As for the overhauling,yes is pain in the .ss and probably will end in the trash bin. Thank you for your time. Quote Link to comment Share on other sites More sharing options...
Szymon Posted August 20 Report Share Posted August 20 "This freewheel must be bedded in before trials use, to ensure any excess grease used when assembling the freewheel works away from the mechanism. You can do this by riding the freewheel around 'normally' for a few hours, both freewheeling and engaging the mechanism gently. If the freewheel is subjected to trials use without having been bedded in, the pawls will not engage correctly and this causes the freewheel to skip, damaging the pawls and ratchet. If you wish to speed up this process, you can thin the grease down with light oil like GT85 or WD40, by spraying it between the centre and outer teeth of the freewheel and rotating it." 1 Quote Link to comment Share on other sites More sharing options...

La Bourde Posted August 20 Report Share Posted August 20 It is not a silly question! It has a thread, but I am not sure about the width of the freewheel. As you can see on the picture, there is a kind of snap ring on one side making the freewheel quite wide. If your bottom bracket axle is wide enough, that shall fit! 1 Quote Link to comment Share on other sites More sharing options...

BTW,Adam was right.Part of the problem was left side crank arm but the bigger one was freewheel. Quote Link to comment Share on other sites More sharing options...
