Check each bearing cap (1) for the location on the engine. Each bearing cap has an arrow which points toward the front of the engine and a number which gives the location of that bearing cap. Keep each bearing with the correct bearing cap.
Remove the bearing caps No. 2 through No. 6. Remove thrust plates from No. 4 upper bearing.
Install one of the flywheel bolts in each end of the crankshaft. Fasten a hoist to the crankshaft. Remove No. 1 and No. 7 main bearing caps. Remove the crankshaft. The weight of the crankshaft is approximately 180 kg (400 lb).
Be careful not to damage the crankshaft journals when removing the crankshaft.
