Looking ofr info from any of you guys who have split cases on the 426 or 450, I would like to know what tools you prefer for crank removal and installation.
The Yamaha tools listed in the manual are produced by K&L Supply and i can get them but I am wondering if those are the best choice for the job?
Motion Pro sells a case splitter but it appears that to get the crank re-installed in the case there is really nothing else available?
Anyone have info?
Thanks!

I've never had a problem getting cases apart just using a good heavy rubber mallet and a little patience , usually no more than 5 mins or so . You dont have as much control when you're at the last few mm's before the cases are apart but with a little care you wont have a parts explosion when your finished ! You can use a little heat on the bearings too if they're holding the crank tightly ....

I agree with Batmandog. Never had to use any special tools other than a rotor puller.

Thanks Batmandog,
I actually went at it before I read this post and just started to take it apart.
It came apart suprisingly easy, no parts explosion at all and the crank just slipped right out.
Now I am reading the manual to try and find out what to look for as far as worn tranny parts.

This motor really did not need to come apart but it is an "extra" motor after my recent WR rebuild so I decided to build another bike with ebay parts and do ALL of the engine work myself.
I cant believe after taking this thing apart that I actually ever paid anybody to do the work for me before, but fear will do that to you I guess.
Anyway, thanks for the reply, I am sending the crank off to Falicon tomorrow for balancing and a new knife rod, because I know that the small end of the stock rod is worn.

I know ya did Tdub,
The only bummer is that Falicon does not make a knife rod for the 426, but ProX does,
Has anyone ever used a ProX rod in a 426? results? failures?
