There have been several posts on this in the past. but briefly. 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

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.
