Remove Flywheel Housing
Start By:a. remove crankshaft rear seal and wear sleeve 1. Remove two bolts (1) that hold bracket assembly (2) in position on the flywheel housing. 2. Remove the bolt that holds clip (3) in position on the cover for the oil filter bypass valve. Remove four bolts (4), and move bracket assembly (2) away from the flywheel housing. 3. Remove the bolt that holds brace (5) to the aftercooler. Remove the bolt that holds brace (6) to the flywheel housing. Loosen clamp (7). 4. Fasten tool (A) and a hoist to the top of the air cleaner housing.5. Remove four bolts (9) that hold air cleaner support (8) against the flywheel. Remove the air cleaner housing and support. The weight of the air cleaner housing and support is approximately 23 kg (50 lb). 6. Disconnect oil line (11) from the cylinder block. 7. On engines with hot manifolds, remove the nuts and bolts that hold clips (16) to shield (17). Remove the two bolts that hold oil line (11) to the top of the turbocharger. Remove oil line (11).8. Remove the two bolts that hold oil line (18) to the bottom of the turbocharger. 9. Remove shield (25) and clamp (26) from the exhaust manifold. 10. On the other side of the engine, remove clamp (27) and support (28). 11. Fasten two straps and a hoist to turbocharger (29) as shown. Remove the four nuts that hold the manifold and turbocharger to plate (30). Remove turbocharger (29) and the manifold from the engine as a unit. The weight of the turbocharger and manifold is approximately 72 kg (158 lb).12. Remove plate (30) and adapter (31) from the flywheel housing. 13. Remove the bolts that hold the oil pan to the flywheel housing. Loosen the rest of the bolts that hold the oil pan in position.14. Install tooling (B) and a hoist to the flywheel housing, as shown. 15. Use tooling (B) and a hoist to lift the end of the engine enough so a 1/2" hardened washer (32) can be installed on each side of the engine between the oil pan and the cylinder block.16. Remove the blocks from under the flywheel housing. Put a block under the oil pan to give support to the rear of the engine. Lower the rear of the engine down on to the block.
Typical Example17. Remove two covers (33) from the flywheel housing. 18. Remove the bolts that hold flywheel housing (34) in place. Remove flywheel housing (34). The weight of the flywheel housing is approximately 84 kg (186 lb).Install Flywheel Housing
1. Install two 1/2" - 13 NC × 4" long guide bolts in the cylinder block. Make sure gasket (2) is in position. The cylinder block, both sides of gasket (2), and the surface of the flywheel housing that makes contact with the gasket must not have any oil, fuel, water, or gasket adhesive on them when the flywheel housing is installed
