2. Remove the pistons and connecting rods as described in paragraph 10. Unless any work is to be done on the pistons and connecting rods, there is no need to remove the cylinder head or remove the pistons from the cylinders. You just need to move the pistons up far enough to clear the connecting rods from the crankshaft journals.
3. Check the crankshaft end clearance as described in paragraph 14, and then proceed as described below.
4. Unscrew the bolts and remove the crankshaft oil seal housing from the end of the cylinder block where the timing belt is located (figure 11.4). Remove the corresponding gasket (if available).

5. Remove the oil pump drive chain and remove the drive sprocket and spacer (if available) from the end of the crankshaft. Remove the woodruff key and store it in a safe place along with the sprocket (figure 11.5, a-c).

6. The main bearing caps must be numbered 1 through 5, starting from the end of the engine where the gearbox (flywheel) is attached to it (figure 11.6). If there is no marking, mark the caps accordingly using a center punch. Also mark the installation depth of the seal in the bearing cap.

7. Unscrew the main bearing cap mounting bolts and remove the caps. Remove the lower main bearing shells and tape them to their respective caps and store them in a safe place. Also remove the lower thrust washers (half rings) from main bearing cap No. 2 (figure 11.7). Remove the sealing strips from the sides of main bearing cap No. 1 and discard them.

8. Carefully remove the crankshaft (figure 11.8) and discard the cuff.

9. Remove the upper bearing shells from the cylinder block (figure 11.9) and using adhesive tape, attach them to the corresponding lids and put them away in a safe place. Remove the upper thrust washers (half rings) from main bearing No. 2 and store them in a safe place along with the lower washers.
