2014 YZ450F cracked case

12 posts in this topic

So i was out riding last weekend and cased a jump pretty good, and there must of been a rock or something cause I now have a cracked case just above where the drain plug is on the back of the motor. 

 

What I really want to know is, is can a person that is mechanically savvy and has worked on bikes for a long time handle this project? Do I need any special tools? If so are they expensive? Anything to replace while I'm in there?

Picture would be nice. How severe is the crack? Does oil pour out? Is there wetness on the case at all? If the crack isn't too severe you could repair or patch it with jb weld.

The job can be done by people such as you describe.  There are quite a few pieces involved, and attention to detail is important, but it's not outside the ability of anyone with slightly better than average skills.

 

You will need a flywheel puller, no question, at less than $20.  Other than that, you can get along pretty well without most of the other stuff.  Do have a manual handy , though.

If that was mine, it would come apart and go get welded and machined.  Either that, or new cases.  That's not the sort of thing that should be epoxied.

Yeah Im going to be replacing with new cases. For both of them I can replace it for $616 from the dealer I purchased the bike through.

It's a nearly new bike, your making the right choice by fixing it correctly. Strong username to post content ratio btw!

Not sure what you mean about the username. Anyway it was a nickname from when I was younger

While certainly not intentional, it looks like you have made a bit of a mess out of that case :)
