1998 King Quad 300 Rear Axle

[kgrant]

Fixing up a 1998 King Quad 300. The rear brake was locked up, and the owner tried to force it free and snapped the axle.

 

I disconnected the brake cable, and tapped on the backing plate with a soft mallet to get the brake freed up. When I pulled off the brake drum a bunch of nasty rust water came out.

 

Once I had the axle out, I popped the boot off so I could see the inner u joint so I could phase/synchronize it with the outer. There was a flat steel disc floating around in the boot, looks like it used to be pressed into the end of the axle. Glad I got that out of there before it munched up the joint.

 

The book says the yokes should be aligned, I couldn't get mine aligned. They were always 7 degrees off from each other. A bit frustrating, maybe that's within the tolerance limits?

 

But I got it all back together and it runs great.

That’s some nice work! I can’t believe that axle snapped like that. Probably avoided a complete and costly failure with the water and metal  in there.
