Transaxle Disassembly
- Remove transmission from transaxle. Remove neutral start switch. Remove speedometer driven gear housing from extension housing. Remove extension housing and gasket. Remove speedometer drive gear. Remove output shaft sleeve.NOTE: Be careful not to lose locking balls.CAUTION: DO NOT turn transmission over as this will contaminate valve body with foreign materials in bottom of pan.
- Remove pan and gasket. Examine particles in pan. Remove magnet and use it to collect any steel chips. Look carefully at chips and particles in pan and on magnet to anticipate what type of wear may be found in transmission.
- Steel (magnetic) means bearing, gear or clutch plate wear. Brass (nonmagnetic) means bushing wear. Turn transmission over and remove tubes by prying up both tube ends with a large screwdriver. Remove screen.
- Remove valve body by removing fourteen bolts, six steel balls and valve vibrating stopper. To remove accumulator pistons and springs, position a rag to catch each piston and using low pressure compressed air, 14 psi (1 kg/cm2
) pop each piston into rag. See Fig 1 .CAUTION: Keep face away to avoid injury. DO NOT use regular high pressure air.
- Remove park lock rod, spring, pivot pin and parking lock pawl. Remove spacer by unstaking spacer and turning ring 90 degrees. Using a hammer and punch, drive out slotted spring pin and remove manual valve lever shaft. See Fig 2 .
- After removing bracket bolt, remove pump suction tube. To remove oil pump delivery tube and pressure tube, pry up both tube ends with a large screwdriver and remove tubes. Remove oil pump by loosening three pump body-to-pump body (inner) bolts and removing seven pump body-to-case (outer) bolts, then pull pump from case. See Fig 3 .
- Remove input shaft, driven sprocket and chain by removing snap ring and pulling both sprockets out uniformly. Place case, facing up, on a wooden block and remove front support. Measure clearance between case tip and front clutch tip for reference at reassembly. Clearance should be .024-.063" (.6-1.6 mm). See Fig 4 .
- Remove front clutch and bearings by grasping shaft and pulling out front clutch assembly. Be careful of bearings and races on both sides of assembly. Remove output shaft and front planetary gear. Grasp rear clutch hub and pull it from case. Remove two center support bolts. See Fig 5 .
- From front opening of case, grasp center support and sun gear assembly and pull it from case. Using a long screwdriver, compress reaction plate and lift retaining snap ring above groove with a wire hook and remove. Remove rear No. 2 one-way clutch and rear planetary gear. See Fig 6 .
- Remove brake No. 3 disc, plate and cushion plate. Remove rear planetary ring gear. Basic Disassembly is complete. Transmission is now in basic component subassemblies. To disassemble, clean, inspect, repair and assemble subassemblies, See COMPONENT DISASSEMBLY & REASSEMBLY .
