PLATE ASSEM. 6P5365 - Caterpillar

Start by:a. Remove rocker arm and shaft assemblies.b. Remove fan drive. When removing cover (1) from the timing gear cover, remove the Allen head screw first. The ten bolts holding the cover will keep pressure on the gasket, which will allow the Allen head screw to be removed more easily. After the allen head screw has been removed, remove the remaining ten bolts from cover (1).1. Remove cover (1) from the timing gear cover. 2. Remove bolts (3) and cover (2) from the flywheel housing.3. Remove plug (4).
For additional information on positioning the crankshaft and camshaft at the compression stroke for No. 1 cylinder (TDC), refer to the Testing & Adjusting Manual.
4. Put the camshaft and crankshaft in the compression stroke position (TDC) for the No. 1 piston as follows: a. Insert the longer bolt (3) [from cover 2] into the hole for plug (4).b. Push bolt (3) against the flywheel. Use a ratchet and tooling (A) to turn the engine and flywheel (in the direction of engine rotation) until bolt (3) seats into the hole in the flywheel.c. Make sure the mark on timing gear (5) and casting rib "X" on timing gear cover (6) are in alignment.
Do not turn the crankshaft or camshaft while camshaft timing gear (5) is removed whenever the rocker shaft assemblies are installed. Damage can be caused to the pistons and valves, or both.
5. Disconnect the wire and remove timing sensor (7).6. Remove one bolt (8) and install a guide bolt (tool B) as shown.7. Remove the remaining six bolts (8). Use tool (C) and a strap to attach a hoist to gear (5). Remove gear (5). 8. Remove the three bolts (9) and thrust plate (10).9. Remove the camshaft and adapter plate (11). 10. Remove adapter plate (11) from camshaft (12).
Care must be taken when removing the camshaft to not damage the highly finished surfaces of both the camshaft and camshaft bearings. Use the following steps and recommended tooling to avoid damage to the engine and components.
11. Use the rocker arm shaft assembly bolts to install tooling (D) into the bolt holes marked "Y" as shown. 12. Install tool (E) onto timing gear cover (6) as shown. Do not tighten the bolts for tooling (E) at this time.
It is necessary to install two pilots (tool F) onto the camshaft. Tool (F) will support the rear of camshaft (12) as the camshaft is moved out of the cylinder head and into tool (E).
13. Move the cam far enough forward to install one tool (F) into the threaded hole in the end diameter of camshaft (12). Again, move the camshaft forward. Install the remaining tool (F) into the back of first tool (F).14. Start camshaft (12) into the bore of tool (E). Snug the bolts holding tool (E) to timing gear cover (6).
When using tool (G) avoid lifting the camshaft. The camshaft should rest on tooling (D). Lifting of the camshaft can cause misalignment as the camshaft is removed, resulting in damage to
