DISASSEMBLY AND ASSEMBLY
DISASSEMBLY SERVICE POINTS
SEALING CAP REMOVAL
1. Drive a screwdriver into the center of the sealing cap.
2. Bend the screwdriver back to remove the sealing cap.
TRANSAXLE CASE REMOVAL
1. Remove all sixteen bolts securing the transaxle case to the clutch housing.
2. Use snap ring pliers to widen the indicated snap ring. The snap ring will separate from the ball bearing groove, and the output shaft assembly will fall under its own weight.
CAUTION: Do not use a scraper or chisel to remove the transaxle case.
3. Remove the transaxle case from the clutch housing.
1. Shift the 3rd-4th speed shift fork and 5th speed-reverse shift fork in the direction shown.
2. Pull up on the 3rd-4th speed shift rail and 5th speed-reverse shift rail and take them out of the hole in the clutch housing.
3. Slide the 3rd-4th speed shift rail and 5th speed-reverse shift rail in the direction shown and remove them together with the shift forks.
Remove the input and output shafts together.
ADJUSTMENT BEFORE ASSEMBLY
SPACER SELECTION FOR DIFFERENTIAL CASE PRELOAD ADJUSTMENT
1. Put solders [1.6 mm (0.063 inch) diameter, about 10 mm (0.39 inch) long] in the illustrated positions of the transaxle case.
2. Install the taper bearing outer race and differential assembly into the transaxle case.
NOTE: If necessary, replace the differential case and taper bearing before carrying out these adjustments.
3. Install the clutch housing and tighten the bolts to the specified torque.
Tightening torque: 44 Nm (33 ft. lbs.)
4. Remove the clutch housing, and then remove the differential assembly.
5. Remove the outer rase and take out crushed solders.
6. Measure the thickness (T) of the crushed solder with a micrometer and select a spacer according to the following equation.
Spacer thickness: [T + 0.05 mm (0.0020 inch)] to [T + 0.11 mm (0.0043 inch)]
Standard value: 0.05 - 0.11 mm (0.0020 - 0.0043 inch)
ASSEMBLY SERVICE POINTS
>A< 0UTPUT SHAFT/INPUT SHAFT INSTALLATION
Install the input and output shafts together.
>B< 5TH SPEED-REVERSE SHIFT FORK/5TH SPEED-REVERSE SHIFT RAIL/3RD-4TH SPEED SHIFT FORK/3RD-4TH SPEED SHIFT RAIL INSTALLATION
1. Shift the 3rd-4th speed synchronizer sleeve and 5th speed-reverse synchronizer sleeve in the direction shown.
2. Set or assemble the 3rd-4th speed shift rail and fork and the 5th speed-reverse shift rail and fork.
3. While fitting each shift fork in the sleeve, slide the shift rails in the direction shown and install.
4. Insert the 3rd-4th speed shift rail and 5th speed-reverse shift rail into the rail hole in the clutch housing.
>C< SPRING PIN INSTALLATION
1. Align the pin holes in the shift rail and shift fork.
2. Insert the new spring pin. Push it in so that the slit and center axis of the rail are aligned.
>D< SPACER AND OUTER RACE INSTALLATION
1. Install the spacer selected in "ADJUSTMENT BEFORE ASSEMBLY."
2. Using special tools MB990935 and MB990938, press install the outer race into the transaxle case.
>E< TRANSAXLE CASE INSTALLATION
CAUTION: Squeeze out the sealant uniformly, while making sure that it is not broken or excessively applied.
1. Apply a 2 mm (0.08 inch) diameter bead of sealant (Mitsubishi Genuine Part number MD997740 or equivalent) to the illustrated position of the transaxle case.
NOTE: Be sure to install the transaxle case while the sealant is wet (within 15 minutes).
2. Install the transaxle case and expand the snap ring.
3. Tighten the transaxle case mounting bolts to the specified torque.
Tightening torque: 44 Nm (33 ft. lbs.)
4. Place the transaxle upside down and let the snap ring fit in the groove by taking advantage of the output shaft's own weight.
NOTE: After installation, keep the sealed area away from the oil for approximately one hour.
>F< SEALING CAP INSTALLATION
1. Using special tools MB990927 and MB990938, press install the sealing cap onto the case.
2. Evenly press the sealing cap so it is not placed at an angle.
>G< UNDER COVER INSTALLATION
CAUTION: Squeeze out the sealant uniformly, while making sure that it is not broken or excessively applied.
1. Apply a 2 mm (0.08 inch) diameter bead of sealant (Mitsubishi Genuine Part number MD997740 or equivalent) to the illustrated position of the transaxle case.
NOTE: Be sure to install the case quickly while the sealant is wet (within 15 minutes).
2. Install the under cover to the transaxle case and tighten the bolts to specified torque.
Tightening torque: 7 Nm (62 inch lbs.)
NOTE: After installation, keep the sealed area away from the oil for approximately one hour.
>H< CONTROL HOUSING INSTALLATION
CAUTION: Squeeze out the sealant uniformly, while making sure that it is not broken or excessively applied.
1. Apply a 0.2 mm (0.08 inch) diameter bead of sealant (Mitsubishi Genuine Part number MD997740 or equivalent) to the illustrated position of the transaxle case.
NOTE: Be sure to install the case quickly while the sealant is wet (within 15 minutes).
2. Install the control housing to the transaxle case and tighten the bolts to specified torque.
Tightening torque: 18 Nm (14 ft. lbs.)
NOTE: After installation, keep the sealed area away from the oil for approximately one hour.
>I< SPEEDOMETER GEAR INSTALLATION
Apply gear oil (Hypoid gear oil SAE 75W-90 or 75W-85W conforming to API classification GL-4) to the 0-ring of the speedometer gear.
>J< SELECT LEVER INSTALLATION
Apply grease (Mitsubishi Genuine Part number 0101011) to the control shaft sliding portion of the select lever shoe.
INSPECTION
