Snapped my rear axle...need help w/new one
« on: March 10, 2009, 09:30:17 AM »
Well, I just started to remove the axle nut. Didn't seem to be very tight but after my second turn SNAP the axle snapped right where the threads begin. Now I looked at new axles and there seems to be two different part numbers. Anyone now why or which one i would need?

If you look at the numbers on the list you will notice a large black arrow and if you look up what that is its a supercision history and tells you that the 020 is the replacement for 010.

Also if you bother to feed the part number into the other half of the motogrid site it tells you that that part fits cb500/550/750 to 75

No problem, I would advise you to bookmark the motogrid site and try out the part number look up for a few different things, at the very least it means you can look at other, less popular models in the breakers and probably pay less for the part.

Also in 30+years ive have never heard of one snapping before---had to replace em where they rusted solid and had to be cut out, but never broken

An FAQ on parts hunting tips.  I like it!
Can I have a motorcycle when I get old enough?
If you take care of it.
What do you have to do?
Lot’s of things. You’ve been watching me.
Will you show me all of them?
Sure.
Is it hard?
Not if you have the right attitudes. It’s having the right attitudes that’s hard.

Part Number Cross-Reference ("will a xxx from a 750 fit my 400..." etc)

http://www.motogrid.com/pages/parts/viewbybrand/7/default.aspx
select model and part from the left hand menu.
Copy into right hand search box and a list of all the models that part was used on magically appears!
Brilliant!  Thanks BryanJ

Okay, I see what you were saying.  I guess I was looking for the detail from the post I quoted.  Yanno, 'cause he said he has said it like 50 times, lol.

Looking at that pic with my old engineering head on i would say that its been cracked for a while and definately undergreased.

Appologies if i upset anyone but sometimes you do get fed up of repeating answers and just have to rant!!

My not-quite-so-old-but-nearly engineering head says that "sheared" would be a better description than "snapped".

We all know how easy it is to shear a seized bolt when sufficient force is applied...  :'(

I would definitely have to agree that it has been cracked because I didnt use hardly any force and that sucker just broke.
