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,

P.S. In case you were wondering, I've re-posted this message, since the 
original got no replies. Some other pedal question got about 10 replies 
overnight, I was not impressed. (It seems people here only care/know about 
current models. Maybe we should rename the group "current yamahas yahoo 
group?)
