20586603 Volvo.Penta Big-end bearing kit

1. Remove access covers (1) from the sides of the engine. 2. Remove bolt (3) and cap (4) that hold fuel rod assembly (2) to the fuel control shaft. 3. Remove bolts (5) to remove lever assembly (6) and fuel rod assembly (2) as a unit from the cylinder heads. If necessary, use Tool (A) to turn the flywheel until the camshaft is moved in a position so that the fuel rod assembly can be removed between the engine block and camshaft. 4. Remove cover (7) from the left side of the flywheel housing. 5. Remove the bolts and remove plate (8) from the end of the camshaft on the left side of the engine.6. Use Tool (B) to remove drive gear (9) from the end of the camshaft on each side of the engine. Remove the drive gears from the flywheel housing. 7. Remove the bolts and remove washer (10) from the end of the camshaft on each side of the engine. 8. Push valve lifters (11) up away from the camshaft into the cylinder heads and hold the lifters in this position. An O-ring seal can be used to hold the valve lifters up. 9. Install the pilot assembly part of Tool (C) on one end of the camshaft. 10. Install the handle part of Tool (C) on the other end of the camshaft. 11. Pull camshaft (12) out of the engine block until a strap and a suitable lifting device can be fastened to it.12. Put identification on the camshafts as to their location in the engine so they can be installed correctly.13. Remove camshaft (12) and Tool (C) from the engine. The weight of the camshaft is 63 kg (140 lb). 14. If necessary, remove bolts (13) to make a separation of the camshaft.Install Camshafts
1. If the camshafts were taken apart, make sure spacer (2) is in position between the camshaft and camshaft assembly. Put 9S3263 Thread Lock on the threads of bolts (1) and tighten the bolts by hand only to a torque of 45 7 N m (33 5 lb ft). Make sure the camshafts are installed respective to the marks "Rear L.H., Rear R.H." on the ends of the camshafts. 2. Install the pilot assembly part of Tool (A) to one end of the camshaft and the handle part of Tool (A) to the other end.3. Fasten a strap and a suitable lifting device to camshaft (3) and put the camshaft in position and push it into the engine block. The weight of the camshaft is 63 kg (140 lb). Remove the strap, lifting device and Tool (A). 4. Install washers (4) on each side of the engine to hold the camshafts in position. 5. Remove timing pins (5) from their storage positions on each side of the engine. 6. Turn the camshafts until timing pins (5) can be installed through the engine block and into the grooves (slots) in the camshafts. 7. Remove cover (6) and plug (7) from the right front side of the flywheel housing. 8. Put timing bolt (8) in position in the flywheel housing. Use Tool (B) and a ratchet wrench to turn the flywheel (in the direction of normal engine rotation) until the timing pin engages with the hole in the flywheel. The No. 1 cylinder is now at top center. 9. Put drive gears (9) in position on the end of the camshaft on each side. 10. Install plate (11) and the bolts to hold the drive gear to the camshaft. Tighten the bolts evenly to a torque of 100 15 N m (75 10 lb ft). Hit the plate with a hammer and tighten the bolts again to the same torque. Do this until the torque does not change.11. Install gasket and cover (10) over the camshaft.12. Remove the timing pins for the camshaft and install the pins in their storage positions.13. Remove the timing bolt from the flywheel and install the plug in the timing hole in the housing. Remove Tool (B) and install the cover on the housing. 14. Remove O-ring seals from valve lifters (12) and push the lifters down against the camshaft. 15. Install fuel rod assembly (14) and lever assembly (13) as a unit in the cylinder heads. If necessary, use Tool (B) to turn the flywheel until camshafts move enough to permit the fuel rod assembly to move into position.16. Make sure lever assembly (13) is engaged correctly with the fuel injection pump rack and install the bolts. 17. Install the bolts and cap (15) to hold the fuel rod assembly to the fuel control shaft. 18. Install access covers (16) on each side of the engine.19. See the Testing & Adjusting Manual for the correct adjustment of the fuel injection control group.End By:a. install crankcase breatherb. install rocker shafts and push rods
