start by:a) remove air compressorb) remove tachometer drivec) remove crankshaft pulleyd) remove oil pan 1. Install crankshaft pulley bolt (2) in the end of the crankshaft. 2. Remove plug (1) from the timing gear cover and install a 5/16"-18 NC x 2 1/2 in. long bolt in its place. Cover bolt (3) can be used. Turn the crankshaft (clockwise as seen from the front of the engine) until the bolt can be installed into the timing gear and is in the center of the timing hole. This operation is used to make an alignment of the marks on the timing gears and to put the crankshaft in a position to install tooling (A).3. Bend the tabs of the locks from the four bolts (4) that hold suction bell assembly (5) to the oil pump. Remove the bolts and bell assembly (5) from the oil pump.4. Remove the rear oil filter from the engine oil cooler and put tooling (A) in position under the engine.5. Put tooling (B) in position under tooling (A) as shown. 6. Remove two bolts (6), the washers and belt tightener (7).7. Remove the three bolts (8), elbow (9) and the gasket. 8. Loosen the clamp and disconnect hose (12) from the timing gear cover.9. Remove water temperature sending unit (11) from the timing gear cover.10. Remove the two bolts, connector (10) and the gasket.11. Remove the two bolts that hold front support (14) to the tractor frame.12. With tooling (B) lift the engine enough to take the weight off of support (14).13. Remove four bolts (13) and support (14). 14. Make a replacement of bolts (15) and (16) on the top of the timing gear cover with two 7/16" x 14 NC forged eyebolts. 15. Remove the bolt that holds clip (18) for the fuel bleed lines.16. Fasten a hoist to the timing gear cover.17. Remove the bolts and one nut that hold the timing gear cover (17). Put identification on the bolts as to their location for correct installation.18. Remove the bolt used to make an alignment of the timing gears.
Do not cause damage to the crankshaft front seal when the timing gear cover is removed and installed.
19. Pull timing gear cover (17) from the dowels on the cylinder block to remove the water sleeves from the cylinder heads. Remove the timing gear cover and oil pump. The weight of the timing gear cover and oil pump is 130 lb. (59 kg).Install Timing Gear Cover And Oil Pump
1. Clean the contact surfaces of the cylinder block and timing gear cover. Install the timing gear cover gasket on the cylinder block. Cut the gasket even with the cylinder block pan rail. Make sure the water sleeves are installed in the timing gear cover. Put oil on the seals.2. Install two 7/16"-14 NC forged eyebolts in the timing gear cover. Fasten a hoist and put timing gear cover and the oil pump in position on the engine. Make sure the oil pump gear and crankshaft gear are in alignment.3. If necessary use tool (C) to push the water sleeves into the cylinder heads.4. Install the bolts and nut that hold the timing gear cover. 5. Remove the hoist and make a replacement of eyebolts (1) with the original bolts.6. Install the clip to hold the fuel bleed lines. 7. Put the front support in position and install bolts (5) and the washers that hold it to the timing gear cover. 8. Put mount assemblies (7) in position and install bolts (6) and the washers. Lower the engine with tooling (A) and (B) and tighten bolts (6).9. Remove tooling (A) and (B).10. Install the gasket and connector (2).11. Install water temperature sending unit (3).12. Connect hose (4) to the timing gear cover. 13. Install the gasket and elbow (10).14. Install idler pulley (8), the washers and bolts (9) to hold the pulley in position.15. Install the rear oil filter on the oil cooler. 16. Put suction bell assembly (11) in position and install the bolts and locks that hold it to the oil pump.17. Remove the crankshaft pulley bolt from the crankshaft.end by:a) install oil panb) install crankshaft pulleyc) install tachometer drived) install air compressor
