how in the world does my clutch shoe break I am using a stock clutch shoe for my century hawk and have had its running less than one gallo of fuel (just to give you an idea of how long the clutch shoe has been in use). is that normal for it to break or how long do they usually last?

You may have had a defective clutch. It happens. It's not common, but it happens.

I have had clutches that last a year, or more. And I've had them break in a month...

Clutch parts should be considered as "Consumables".

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!
RE-KIT!!!!!

Poor engine alignment. Do a search.

Most common cause i have seen is that the lineing on the bell has got worn so the clutch shoe has to flex out that little bit further till it contacts the lineing. The metal in the clutch can only flex so far and so many times untill it fatigues and breaks. I machine about 3/4 of the old clutch lineing out of the bell useing one of my lathes and then stick the new one in on top of it. Then i machine it out again untill i get about .0004 up to .0006 thou clearance between the clutch and the bell. This does two things, it gets the clutch clearance right and it makes sure the lineing is perfectly round. Havnt had a single clutch fail on me yet.

If it doesnt move and its meant too... use WD 40. If it moves and its not meant too...use duct tape!

Yug is right...if the engine is at an angle compared to the clutch, it will bend back and forth as it goes around. That is, in a setup like a raptor, but not on a Hawk where the clutch and bell is mounted on the engine so it cannot be out of line.

You probably just got a bad clutch.

The government cannot give you anything without first taking it from someone else.

Also take a look at the gap before installing the new clutch
