Ok so I'm sitting on the side of the highway because my rear axel broke in half at 52 MPH. Has any one ever had this problem. This is the second time this has happened to me. This axle has 345 miles on it. Any info or help anyone has would be awesome!
Thanks!
can u graese it up somehow? it may be gettin hot. u could have one machined out of some hard shit at your local machine shop if it continues.
wich snow flakes? and how much do you weigh??
He weighs about 650 lbs when he hasnt eaten for a week, but I dont think his weight is an issue
Well, you ran a 30mph axle at 52mph, are you really that surprised? Use heavy duty automotive grease on the next one, grease the bearings and the axle itself.
I have a pair of snowflakes that I greased with bike grease. I was going to put them on a kitted bike, but you make it seem like a bad idea.
maybe repack them? or does it matter?
I run mine at 50+ all the time. I weigh 220. No probs. I would feel better if they were 12mm instead of 11mm. Did you hit a nasty bump?
did it have scoring because that would indicate bearing failure.
you packed and adjusted them wrong.
:(
You ride your moped on the highway?
What is it like breaking a rear axle at 52mph?
There was no sign on the last one of bearing problems, the axle just sheared apart about 1.5 inches from the end. I dont remember which side it broke on. I dont think it was packed and adjusted wrong. This is far from the first axle that he has installed. And he doesnt weigh 650 its more like 210.
well first off, I used Heavy duty High Heat Super Nice Grease when i rebuild wheels so i dont think that is the problem.
Second, running a 30mph axle at 52 is a dumb idea! but it seems others are doing it with no problem and its never happened on any other wheels of mine, Just the Snowflakes.
ummm.... Im absolutely positive they are and were packed and adjusted correctly.
The Last time this happened there did not seem to be and scoring.
Oh and breaking an axle at 52mph was not even scarry at all. To be honest it felt like running out of gas, it just started to slow WAY down and surging like it was going to die. I did not realize it had broke until i pulled over and investigated the problem.
So yeah, it sounds like no one else has had this problem.
That sucks, well good for you, bad for me. Guess its time to convert to sealed bearing in back with a 12 or 13mm Axel.
The Front was an easy conversion, but the back is going to require more work, but im tired of having to tear the wheels apart and being stranded on the side of the road.
Thanks for the feedback!
oh and todd, I am a Gentlemans 190 lbs! you fat ass!
Its funny that 54.4 was your top speed mine was 55.3. Not really a big deal, maby you should pop that shirt off for more aero dynamics.
im pretty sure when i was looking back at you last night you were about a 1/2 mile behind me all night. its no big deal.
well i guess i lose because you got to ride your bike home.
Why would the rear take more work to convert? 16101ZZ bearings (12x30x8mm) will press right in.
the rear has one side bigger than the other. you have to make a shim to press a sealed bearing in there.
plenty of people have broken axles, just not in the first 500 miles from what I know. you are actually using an axle and not just some threaded rod, right?
bigger by how much?
Yep, New 11mm axle kit from treats. Both of them i have broken were brand new.
by like 2mm. I had to have a 1mm thick aluminum ring machined for it.
I have an original axle that you can have if you paypal me to ship it. I think all aftermarket cylinder studs and axles are crap... Never had luck with them.
We're talking Puch snowflakes aren't we? I should have found that out first. I recently converted two sets of Puch snowflakes, and my bearings are pressed in on both sides and are staying put. Also, the cups that were removed are the same size.
mine are Grimeca snowflakes, for Puch, but instead of actually saying Puch on them they say something else. I can't remember what it is right now though.
Weird. I have a set of Puch-labeled snowflakes that originally came from a Maxi, and a set of Grimeca-labeled snowflakes that originally came from a Pinto. Identical in every way except the lettering.
I couldn't find 30mm bearings for my Grimeca Snowflakes. I picked up some 28mm & machined two bearing cups out of brass.

bump
why did you bump this? i had a front snowflake fail on me. it felt like running out of gas, you're right about that. my problem wasn't the axle so much, but my bearing cups shattered to hell and the bearings clunked together and froze the wheel up. luckily i was going really slow around a traffic circle when it happened! haha.
yep, this has happened to me twice. the main reason i hate puch snowflakes...that and theyre fucking ugly (unless theyre painted)
my axle broke in half the first time. it was really confusing because my bike was still rolling and stuff but it wouldnt break 35mph. we got to a place and i took my rear wheel off, and the axle collapsed and a bunch of bearings fell out. my dad had to come pick me up. :(
I'm with zach on this one. Sounds like they were adjusted wrong for sure. I did this after repacking one. Sucks. Replaced it and actually used a cone wrench and did it right........ Have about 5k miles on it most of which were between 45-50mph and haven't had a single problem since.
