Engine Disassembly (0-01) Section 0 - Engine Disassembly and Assembly - Group 00 M11 Page 0-42 Engine Barring Tool - Installation Use two flywheel mounting capscrews (M14—1.50 x 40) to install the engine barring tool, Part No. 3824270, to the flywheel end of the crankshaft. Piston Cooling Nozzles - Removal Caution: The nozzles must be removed before the pis- ton and rod assemblies to avoid damage to the nozzles. The crankshaft must be rotated to allow access to remove all the nozzles. Remove each retaining capscrew and nozzle. Pistons and Connecting Rods - Removal Caution: Do not use emery cloth or sandpaper to re- move carbon from the cylinder liners and cylinder block top deck surface.
Aluminum oxide or silicon particles from emery cloth or sandpaper can cause serious engine damage. Rotate the crankshaft to expose the carbon ridge above the ring travel area in the cylinder liner. Use a fine fibrous abrasive pad such as Scotch-Brite W 7448, Part No. 3823258 or equivalent, and solvent to remove the carbon. Use the barring tool to rotate the crankshaft to position the rod caps at ‘‘bottom dead center’’ (BDC) for removal. Loosen the connecting rod capscrews. Do not remove the capscrews from the rods until the caps have been loosened.
