Yamaha Service Bond

[David ilvedson]

David/List...

I still do an occasional service bond...Aren't there two service 
bonds for a sale?  The customer for one Yamaha dealer gives the 
customer a free tuning and the service bond in 6 months or so.  
Typically with the service bond I will check the screws in 
sections rather than tighten them all, if needed I will 
tighten...here in CA. they are usually tight.  The regulation 
is rarely in need of adjustment.  I just visually check 
letoff/drop in sections and I might bring down the rep tension 
if too strong.  I certainly tighten the bench bolts and check 
hinge screws/tighten as needed.  Tighten plate bolts slightly.  
Adjust pedals and tune.  The first tuning will insure I have a 
piano up to pitch and I won't need to pitch raise.  I can do 
this in about 1 & 1/2 hours but I am moving quickly.

> tighten every single hinge, case, plate, pinblock and bench bolt
> remove action, tighten all the action and damper flange screws
> Adjust pedals
> Align hammers and other action parts
> Check and adjust keylevel and dip, hammer blow distance, let off, drop,
> checking and dampers as needed.
> 
> If there is a pitch raise and tuning, I add an extra hour to hour and a half.
