UNIT ASSEMBLY
CAUTION:
 Automatic transmission consists of highly precise parts. As even a flaw in a 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 discs and brake band, soak them in automatic transmission fluid for
at least 2 hours.
 Be sure to use new gaskets and O-rings.
 Lubricate O-rings with automatic transmission fluid.
 Apply automatic transmission fluid on sliding or rotating surfaces of the parts before assembly.
 Use yellow petrolatum grease or 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 cor-
rectly.
 Do not use adhesive cements on gaskets and similar parts.
 Be sure to torque each bolt and nut to specification.
