Installation
1. Clean all the mating faces and reusable parts thoroughly and check for damage.
CAUTION: Use only a plastic scraper when removing the sealing material.
CAUTION: If any new bolts are to be installed to retain the crankshaft main bearing carrier, prestress the retaining bolts by installing the crankshaft main bearing carrier without any sealant and tightening the new retaining bolts to the specified torque. Remove the crankshaft main bearing carrier once the bolts have been pre-stressed. Failure to follow this instruction may result in damage to the vehicle.
NOTE: Install the crankshaft main bearing carrier and tighten bolts to specification within twenty minutes of applying the sealant.
2. Apply a 2 mm (0.08in) bead of sealant to the cylinder block in the area shown.
^ Use WSS-M4G323-A4-RTV sealant.
NOTE: Install the crankshaft main bearing carrier and tighten bolts to specification within twenty minutes of applying the sealant.
3. Apply a 1 mm (0.039in) bead of sealant to the cylinder block in the area shown.
^ Use WSS-M4G323-A4-RTV sealant.
4. Install the crankshaft main bearing carrier to the cylinder block.
CAUTION: Make sure all dowels are fully seated into the crankshaft main bearing carrier prior to tightening the bolts.
NOTE: Do not lubricate the crankshaft main bearing carrier retaining bolts.
NOTE: Do not rotate the crankshaft until all the retaining bolts are tightened to specification.
NOTE: The retaining bolts must be tightened within twenty minutes of applying the sealant.
NOTE: Tighten the retaining bolts in the sequence shown.
^ Stage 1: Bolts 21 to 32, tighten to 15 Nm (11 ft. lbs.).
^ Stage 2: Bolts 33 to 34, tighten to 15 Nm (11 ft. lbs.).
^ Stage 3: Bolts 1 to 10, tighten to 25 Nm (18 ft. lbs.).
^ Stage 4: Bolts 11 to 20, tighten to 15 Nm (11 ft. lbs.).
^ Stage 5: Bolts 1 to 10, tighten to 35 Nm (26 ft. lbs.), then a further 135 degrees.
^ Stage 6: Bolts 11 to 20, tighten to 20 Nm (15 ft. lbs.), then a further 150 degrees.
^ Stage 7: Bolts 21 to 32, tighten to 20 Nm (15 ft. lbs.), then a further 90 degrees.
^ Stage 8: Bolts 33 to 34, tighten to 20 Nm (15 ft. lbs.), then a further 150 degrees.
^ Stage 9: Center punch each of the bolt heads to indicate it has been reused.
5. Rotate the crankshaft to check correct operation.
6. Remove excess sealant which may squeeze out at the front cover sealing surfaces.
7. Install the baffle plate.
^ Tighten the 6 bolts to 6 Nm (4 ft. lbs.).
8. NOTE: Make sure that the transit sleeve is correctly positioned and install the new seal over the crankshaft. Do not use any lubricant on the seal, the transit sleeve or the crankshaft.
NOTE: Carefully remove the transit sleeve, leaving the seal in place.
Using the special tool, position the crankshaft rear oil seal.
9. Using the special tool, install the crankshaft rear oil seal.
CAUTION: Alternate the nut tightening to correctly seat the crankshaft rear oil seal.
10. Remove the special tool.
CAUTION: Make sure that the crankshaft rear oil seal is correctly located.
NOTE: Prevent the flexplate from rotating.
11. Install the torque converter flexplate.
^ Clean the component mating faces.
^ Tighten the bolts evenly in 2 stages to the sequence shown.
^ Tighten the bolts to 15 Nm (11 ft. lbs.).
^ Tighten the bolts to 110 Nm (81 ft. lbs.).
12. Install the special tool.
13. Connect the battery positive cable and the switch lead to the starter motor solenoid.
^ Connect the battery positive cable.
^ Connect the electrical connector.
^ Install the battery positive cable cover.
14. Install the starter motor.
^ Clean the component mating faces.
