Disklavier

It seems the right pedal on my Clavinova (cvp 201 series)is now busted due 
to misuse and overuse (it's been almost 4 years now).
It still works, but it makes this AWFUL clanking noise no matter how you 
press it (I've tried altering my pedalling technique to see if that helped)
I now a few of you would be familiar with this problem so I need to know:
1. Can the part be replaced?
2. How much for changing JUST the right pedal? (2 other pedals work fine)
3. If the part replacement is too expensive, can a technician fix it?

I'm in Australia, but I shouldn't have any problems getting the parts or 
service I need, just wanted to hear from you guys first.

thanks in advance,
