235 kg (518 lb) . - Remove two bolts (17) and install Tooling (D). Remove the remaining bolts (17) and remove flywheel housing (16) from the cylinder block.
- If necessary, remove plugs (15) from the flywheel housing.
Note: Ensure that the rear gear group and the crankshaft are properly protected during the cleaning procedure. Ensure that the bolts are cleaned with a wire brush in order to remove debris or residue. Ensure that the bores for the bolts in the cylinder block are tapped again. Ensure that the bores for the bolts are cleaned in order to remove debris or residue.
- After removing flywheel housing (16), clean the mating surface of the cylinder block and the mating surface of the flywheel housing with Tooling (E). If necessary, use a gasket scraper and a solvent in order to remove any residual gasket material. Both mating surfaces must be clean, dry, and free of any oil before installation.
