1994 MAZDA MX-5 check oil

TRANSMISSION K Procedure 1. Place wooden blocks under the transmission at the con- verter housing and the extension housing positions. 2. Remove the oil pan and gasket. Examine any material found in the pan or on the magnet to determine the condition of the transmission. Clutch facing material . . . . . Drive plate and brake band wear Steel (magnetic) . . . . . . . . . . Bearing, gear, and driven plate wear Aluminum (nonmagnetic) . . Bushings or cast alumi- num parts wear If large amounts of material are found, replace the torque converter and carefully check the transmission for the cause. 3. Install the oil pan and gasket with a few bolts to protect the valve body. 4. Remove the vacuum diaphragm, lockup control solenoid valve, vehicle speed pulse generator, and O-rings. 5. Remove the parwneutral switch. 6. Remove the speedometer driven gear from the exten- sion housing. 7. Remove the O-ring from the speedometer driven gear. Gartner Banana

TRANSMISSION K 41. Remove the oil distributor. 42. Remove the bearing. TORQUE CONVERTER Inspection 1. Check the outside of the converter for damage and cracks, and replace the torque converter if there is any problem. 2. Check for rust on the pilot hub or on the boss, and re- move the rust completely if there is any. Washing inside the converter 1. Drain any ATF remaining in the converter. 2. Pour in solvent (0.5 L, 0.5 US qt, 0.4 Imp qt). 3. Shake the converter to clean the inside. Pour out the sol- vent. 4. Clean the inside of the converter with compressed air so that the inside is completely empty. 5. Pour in ATF. 6. Shake the converter to clean the inside. Pour out the ATF. Gartner Banana

K TRANSMISSION DIRECT CLUTCH Preparation SST CLOCKWISE 49 0378 375 Compressor, clutch spring Preinspection Direct clutch operation 1. Install the direct clutch onto the drum support along with the seal rings. Apply compressed air through the oil passage as shown. For removal 1 installation of direct clutch Air pressure: 392 kPa (4.0 kgtcm*, 57 psi) max. 2. Verify that the side plate moves toward the snap ring. If not, the seal ring or O-ring may be damaged or fluid may be leaking at the piston check ball. Inspect them, and re- place as necessary when assembling. Clearance between side plate and snap ring 1. Measure the clearance between the side plate and the snap ring. Clearance Maximum: 0.2mm (0.008 in) i -, 2. Select and install the correct side plate when assern- bling. One-way clutch operation Insert the fourth gear clutch hub on the top of the direct clutch, and verify that the fourth gear clutch hub rotates smoothly when turned clockwise and locks when turned counterclockwise. If not, replace the one-way clutch. Gartner Banana

TRANSMISSION K 21. Insert the fourth gear clutch hub on the top of the direct clutch and verify that the fourth gear clutch hub rotates smoothly when turned clockwise and locks when turned counterclockwise. If it does not, then the one-way clutch is installed upside down. Caution Applying compressed air to the assembled clutch pack for longer than 3 seconds at a time will dam- age the seal. 22. Install the direct clutch onto the drum support along with the seal rings. Apply compressed air to the oil passage and check the clutch operation. Air pressure: 392 kPa {4.0 kglcm2, 67 psi) max.

TRANSMISSION K Disassembly note Piston assembly Remove the piston assembly from the body by applying compressed air through the oil passage hole. Air pressure: 392 kPa f4.0 kg/cm2,57 psi) max. Inspection Return spring 1. Measure the spring specifications. I Outer dia. I Free length I No. of tolls I mm (in) mm {in) mm {in} 2. If not within specification, replace the return spring. Assembly procedure 1. Apply ATF to the new seal rings, and install them onto the body. 2. Apply ATF to the new O-rings, and install them onto the piston assembly. 3. Apply ATF to the piston assembly and body. 4. Apply even pressure to the perimeter of the piston, and install it into the body. 5. Verify that the piston can be turned by hand. If it cannot, then remove it and check for damage to the seal ring. 6. Apply ATF to the piston stem and washer, and install them into the body. 7. Loosely tighten the nut. Gartner Banana

TRANSMISSION K 2. Apply ATF to the spring and install it into the fourth gear case. 3. Apply ATF to the accumulator piston. 4. Apply even pressure to the perimeter of the piston, and install it into the fourth gear case. 5. Verify that the piston can be turned by hand. If it cannot, then remove it and check for damage to the seal ring. 6. Apply ATF to a new O-ring, and install it on the accumula- tor plug. 7. Install the accumulator plug and snap ring. Caution Applying compressed air to the assembled clutch pack for longer than 3 seconds at a time will dam- age the seal. 8. Check the accumulator operation by applying com- pressed air through the oil passage. Air pressure: 392 kPa (4.0 kg/cm2, 57 psi) max. 9. Apply ATF to the plug, and install it into the drum support. 10. Tap in a new roll pin. 11. Set the oil pump onto the SST. 12. Apply ATF to a new seal ring, and install it onto the drum support.

K TRANSMISSION FRONT CLUTCH Preparation SST Preinspection Front clutch operation 1. Install the front clutch onto the drum support along with the seal rings. Apply compressed air through the oil pas- sage as shown. 49 0378 375 Compressor, clutch spring Air pressure: 392 kPa (4.0 kglcm*, 57 psi} max. For removal / installation of front clutch 2. Verify that the retaining plate moves toward the snap ring. If not, the seal ring or O-ring may be damaged or fluid may be leaking at the piston check ball. Inspect them, and replace when assembling. Clearance between retaining plate and snap ring Measure the clearance between the retaining plate and the snap ring.
