Removal and Installation

GENERAL INFORMATION
The crankshaft is supported in four main bearings. All upper bearing shells in the crankcase have oil grooves. All lower bearing shells in stalled in the monoblock main bearing cap are plain. Crankshaft end play is controlled by thrust washers on the number three main bearing journal.





REMOVAL
1. Remove front mounted oil pump assembly and gasket.





2. Remove rear oil seal retainer and seal as assembly.
3. Release monoblock main bearing cap bolts evenly. Remove lower bearing shells and identify for reassembly.
4. Lift out crankshaft and remove upper thrust washers from each side of number three main bearing in the crankcase.





INSTALLATION
1. Install upper main bearing shells making certain oil holes are in alignment, and bearing tabs seat in block tabs. All upper bearings have oil grooves.
2. THRUST BEARINGS. Crankshaft thrust bearings (washers) are installed at journal #3 separately from the radial bearings. Thrust bearings are different, one has end positioning tabs, while the other is plain. One pair of each thrust washers are installed into the block and one pair into the main bearing cap.
3. Apply a thin film of grease to plain side of thrust washers and position them on each side of number three main bearing. Grooved surface towards crankshaft.
4. Oil the bearings and journals and install crankshaft.
5. Install lower main bearing shells without oil grooves in monoblock cap.
6. Install one pair of thrust washers in cap.





7. Carefully install bearing cap with arrows toward timing belt end.
8. Oil the bearing cap bolt threads, install and tighten bolts progressively in sequence shown to 94 Nm (69 ft. lbs.) torque.
