Wim says: After the truck has been installed go around and tighten all the bolts. I like one refinement to this: as the third arm goes under,fully tighten its set screw and its bolt at the edge of the center panel. Then take the weight off the other two legs in turn as you tighten their screw and bolt, finishing with the center bolt. Taking the weight off the arms as they are tightened seems to get even more sag out of the truck. Don't forget to take sockets and power screwdrivers for Japanese and other pianos which don't have popout casters - you'll need to take off each leg in turn and unscrew the casters.? I agree that the wood blocks make it possible to do any size piano alone.

Get 2 blocks of 2x4 about 4 inches long. You will also need a jack, or Susan Graham's jack box. (available from Jansen) Be sure to read the directions on how to assemble?the truck. Once you've got the truck assembled, and under the piano, lift up the bass end leg with the jack,?and?remove the caster.?Position the arm under the leg, and push one of the 2x4 under the arm. Slowly release the jack. Go to the tremble end leg, and repeat the previous procedure. Go to the back leg, jack it up, remove the caster, and put the back arm under the back leg. Release the jack, and you're in business. ? When you install the truck, be sure the bolts on the center disc are tight. Loose enough to be able to rotate the arms, but they need to be tight, especially the one in the middle. If you don't get them tight, the truck will bow in the middle, and the bolts under the leg caps will scrape on the ground. After the truck has been installed go around and tighten all the bolts. good luck Willem (Wim) Blees, RPT Piano Tuner/Technician Mililani, Oahu, HI 808-349-2943 Author of: The Business of Piano Tuning available from Potter Press www.pianotuning.com -----Original Message----- From: pgmilkie at juno.com <pgmilkie at juno.com> To: Pianotech at ptg.org Sent: Mon, 19 Jan 2009 5:54 pm Subject: [pianotech] Grand Piano Truck instalation Just received an email asking if I could install a grand piano truck on a church piano. I emailed back requesting name of piano and length of the grand. After 33 years of tuning I have not installed a grand piano truck. After removing the casters and extending the adjustable arms on the piano truck, which leg should I start with? Thank you in advance for guiding me.
