Inspection
Brake discs
Dry and inspect them for pitting, burn flaking, significant
wear, glazing, cracking, charring and chips or metal
particles imbedded in lining.
If discs show any of the ab ove conditions, replacement
is required.
NOTE
• If disc lining is exfoliated or discolored, replace all discs.
• Before assembling new discs, soak them in A/T fluid for at least two hours.
Brake separator plates and retaining plates
Dry plates and check for discol oration. If plate surface is
smooth and even color smear is indicated, plate should
be reused. If severe heat spot discoloration or surface
scuffing is indicated, plate must be replaced.
Brake return spring subassembly
Measure free length of each brake return spring
subassembly.
Evidence of extreme heat or burning in the area of clutch
may have caused springs to take heat set and would
require their replacement.
Free length of 1st & reverse brake return spring
subassembly
“a”: 21.71 mm (0.855 in.)
Free length of 2nd brake return spring subassembly
“a”: 15.85 mm (0.624 in.)
NOTE
• Do not apply excessive force when measuring spring free length.
• Perform measurement at several points.

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 cut outs 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.
