CAUTION!
• Automatic transaxle consists of highly
precise parts. As even flaw in small part
may cause oil leakage or decrease in
function, check each part carefully before
installation.
• Clean all parts with compressed air. Never
use wiping cloths or rags.
• Before assembling new clutch or brake
discs, soak them in automatic transaxle
fluid for at least 2 hours.
• Be sure to use new gaskets and O-rings.
• Lubricate O-rings with automatic transaxle
fluid.
• Apply automatic transaxle fluid on sliding
or rotating surfaces of the parts before
assembly.
• Use Suzuki Super Grease “C” to retain
parts in place.
• Be sure to install thrust bearings and races
in correct direction and position.
• Make sure that snap ring ends are not
aligned with one of cutouts and are
installed in groove correctly.
• Do not use adhesive cements on gaskets
and similar parts.
• Be sure to torque each bolt and nut to
specification.
