Remove the valve mechanism cover, the glow plugs, and the cover for the front housing. Refer to Disassembly and Assembly, "Front Cover - Remove and Install". Note: The crankshaft timing pin can be inserted with the crankshaft pulley still on the engine.
Use tooling (A) to rotate the crankshaft in the normal direction of the engine until the inlet valve of the No. 4 cylinder has just opened and the exhaust valve of the No. 4 cylinder has not completely closed. Note: Use the alternative Tooling (D) and Tooling (E) if the access to the front of the engine is restricted.
Carefully rotate the crankshaft in the normal direction of the engine in order to align the hole in the crankshaft with the hole in the cylinder block (2) and the timing case. Insert Tooling (B) fully into the hole in the crankshaft web.
Insert Tooling (C) through the hole in the camshaft gear (1) at the top center position for No. 1 piston. Note: The camshaft gear can rotate a small amount when the pin is installed.
Remove the timing pins from the camshaft gear and the crankshaft web.
