So, after about 2.5 years of being lazy, I'm planning on getting my NST underdrive pulley set installed.

Full parts list:
NST02020 (20% underdrive crank pulley)
NST02022 (20% overdrive alternator pulley)
NST02025 (water pump pulley)
K060747 belt

I finally found someone to do the install, and have an appointment set up next week. I'm also trying to search through some historical threads for some tips on install, and I found these so far:

https://www.scionlife.com/forums/tc-tech-diy-1818/pulley-install-nst-underdrive-crank-water-pump-alternator-44310/ (from WDS way back in 2006; covers procedure for all three pulleys)
https://www.scionlife.com/forums/sho...d.php?t=156038 (from Sizzource on an xB2)
https://www.scionlife.com/forums/sho...d.php?t=158179 (from NST on an xD)

This is for a 2006 tC; the recommended belt size was K060747 (6-rib; 74.7"), but I saw in one of the threads that they had to go with a K060755 equivalent because it didn't fit. Anyone else know what size belt they used?

I'm being asked to gather instructions and necessary tools for the install; it looks like the most complex tool is a gear puller for removing the crank pulley. Let me know of any other tips and/or threads; I'll update this after the install.
