1. Remove two socket head bolts (1).2. Remove bridge (2). 3. Remove ten or fourteen bolts (3).4. Remove five or seven bearing caps (4). Mark or identify for later installation.5. Remove the lower half bearings and the upper and lower thrust washers. Keep the bearings with their respective caps. 6. Remove eight or twelve nuts (5).7. Remove four or six connecting rod caps (6). Mark or identify for later installation.8. Remove the bearings from rod caps (6). Keep the bearings with their respective caps.9. Remove eight or twelve connecting rod bolts (7).10. Carefully push the pistons into their bores. 11. Attach straps and a suitable lifting device to crankshaft (8).12. Carefully lift the crankshaft out of the engine block. The weight of the crankshaft is 29 kg (65 lb). Do not nick or scratch any of the finished surfaces on the crankshaft.13. Remove the upper half bearing and place with the relevant lower half bearing for installation. The following steps are for the installation of the crankshaft.14. Make sure that all the lubricating passages are clean and free of debris.15. Clean the main bearing housings.16. Clean the upper half bearings.17. Position the bearings with the location tabs correctly positioned into the recesses. Lubricate the bearings with clean engine oil.18. Make sure the main journals of the crankshaft are clean.19. Position the crankshaft into position on the upper half bearings.20. Clean and lubricate the upper half thrust washers and slide them into position onto the recesses on both sides of the bearing housing.
Be sure the slotted sides of the thrust washers are towards the crankshaft.
21. Clean the bearing caps and the lower half bearings.22. Install the bearings to the caps with the location tabs correctly positioned into the recesses. Lubricate the bearings with clean engine oil.23. Clean and lubricate the lower half thrust washers and slide them into position on both sides of the bearing cap for the center main bearing.24. Check that the location thimbles for the main bearing caps are positioned correctly in the caps or in the cylinder block. Install the bearing caps in their correct position (as shown by the position number stamped on the top of the cap) with the location tabs of the bearing on the same side. In this position the serial numbers stamped on the bearing caps will be in line. The serial number stamped on the bearing caps must be the same number stamped on the bottom face of the cylinder block.25. Install the bolts to the main bearing caps. Tighten them gradually and evenly to a torque of 265 N m (196 lb ft).26. Clean the bridge piece and the location areas for the bridge piece in the cylinder block. Apply a thin strip of 8T9013 Red RTV Silicone in the corners and around the thread holes of the bridge piece seat in the cylinder block. Install the bridge piece and the rubber seals (if equipped). The rubber seals (if equipped) will be a little higher than the bridge piece when they are installed correctly. Use a straight edge to be sure the that the bridge piece is in line with the rear face of the cylinder block. Tighten the bridge piece cap screws. A bridge piece has been introduced which uses 8T9013 Red RTV Silicone instead of the rubber seal in the groove at each end of the bridge piece. The groove at each end of the new bridge piece is cast and is off center. The procedure to install the new bridge piece is the same as for the earlier bridge piece except for the following instructions. Apply 1/8 3.0 mm ( inch) bead of 8T9013 Red RTV Silicone along the corner in the top of the recess in the cylinder block for the bridge piece. When the bridge piece is in position and the cap screws have been tightened, inject 8T9013 Red RTV Silicone into the groove at each end of the bridge piece until the groove is completely filled. When the pan gasket is removed, damage can occur to the 8T9013 Red RTV Silicone seal in the grooves of the bridge piece. If the seal is damaged, apply sufficient 8T9013 Red RTV Silicone to completely fill the grooves. Most of the latest engines have setscrews instead of studs to fasten the pan to the bridge piece. The threads of the setscrews have a sealant applied by the manufacturer. When the setscrews are used again, be sure that the threads of the cap screws and the bridge piece are clean and 9S3263 Thread Lock is applied to the threads of the setscrews. These instructions would also apply to studs.27. Install the connecting rod caps. Turn the crankshaft two complete revolutions to check for free movement.28. Install the lubricating oil pump, the lubricating oil suction pipe and strainer, the delivery pipe and the relief valve.End By:a. install oil pumpb. install rear oil seal housingc. install flywheel housingd. install fuel injection pump
