Hello,

I was able to solve my problem by downloading a pdf of the
"Toro/Lawn-Boy Walk Behind Power Mower Drive Systems Manual" from
Toro's website (www.toro.com.) Unfortunately, the Interactive Manual
was incorrect for replacing the v-belt on my mower. Anyway, the
Service Manual is quite detailed and it states that it covers models
from 1990 to 2002 (my mower is a 2005 and the manual was good.) It
describes how to disassemble and reassemble all the different
transmissions. Perhaps you may just need to add some #2 lithium based
grease to quiet things down. I wish you luck.
