Remove the timing gear cover. Refer to Disassembly and Assembly, "Housing (Front) - Remove".
Remove the rocker shaft assembly and the pushrods. Refer to Disassembly and Assembly, "Rocker Shaft and Pushrod - Remove".
Remove the oil pan. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install".Note: The engine oil pan is facing in the up direction in order to retain the lifters in position for this procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Note: Ensure that the marks on the timing gears are in alignment. Align the fuel injection drive gear with the "33" mark with the "3" mark on the idler gear. Make an alignment of the "2" mark on the camshaft gear with the "22" mark on the idler gear. Align the "1" mark on the crankshaft gear with the "11" mark on the idler gear. The No. 1 cylinder is at the top center position when these marks are in alignment.
Rotate the engine at 180 degrees.

Install thrust plate (4) onto camshaft (5) .
Always wear protective gloves when handling parts that have been heated.
Heat camshaft gear (2) in an oven to a maximum temperature of 150 °C (302 °F) and install camshaft gear (2) onto camshaft (5) .
Install the 12 valve lifters. Refer to Disassembly and Assembly, "Lifter Group - Remove and Install".Note: During installation, ensure that the marks on the timing gears are in alignment. Align the fuel injection drive gear with the "33" mark with the "3" mark on the idler gear. Make an alignment of the "2" mark on the camshaft gear with the "22" mark on the idler gear. Align the "1" mark on the crankshaft gear with the "11" mark on the idler gear. The No. 1 cylinder is at the top center position when these marks are in alignment.
Carefully install the camshaft assembly into the original location in the cylinder block.Note: Caution must be used when the camshaft is installed in order to not damage the camshaft l
