Install New Turbocharger
Before removing the existing turbocharger, check the part number on the turbocharger identification plate (refer to Illustration 1). If the part number is 1005864 or 1005865, DO NOT install a new turbocharger. If a machine in Group 1 has a turbocharger with a part number of 4P4677, 9Y4230, or the identification plate is missing, install a new turbocharger.
1. Remove the former turbocharger and air intake hose. Inspect hose and piping for signs of dirt entry, and correct as needed. Inspect condition of 8T7044 mounting studs and 8C8734 Locknuts and replace if needed.2. Install the new 1005865 Turbocharger. Use 5P3931 Antiseize Compound on the threads of the mounting studs. Install the new mounting gasket and oil supply/drain gasket. Tighten the locknuts to 54 5 N m (40 4 lb. ft).3. Install the new air inlet hose (15 cm of 5P1263 Hose). The hose is slightly shorter than the former air inlet hose because the compressor housing of the new turbo is slightly longer. Tighten the 8T6675 Constant-Torque-Type Clamps to 11 2 N m (9 2 lb. ft). Refer to the Service Manual, Engine Disassembly & Assembly section concerning the Turbocharger removal and installation.Adjust Fuel Injector Timing - Check/Adjust Fuel Setting - Check/Adjust Low Idle Rpm To 950 Rpm
Refer to the Service Manual, Engine Section, Testing and Adjusting for the correct procedure to set injector Fuel Timing and valve clearance, and the Fuel Setting procedure.
1. Remove the valve cover sound suppression cover and valve cover.2. Check the Fuel Setting. The correct Fuel Setting is shown on the Engine Information plate, "Full Load Static Fuel" Refer to Illustration 2. Set the Fuel Setting as closely as possible to the specified setting. DO NOT set Fuel Settings "to the high side" of tolerance. If Fuel Setting is adjusted, install lockwire and a dealer seal.3. Set the fuel timing to a specification of 64.16 mm. Also, check and adjust the valve clearance. The tightening specification for the injector rocker arm adjusting nuts is 39 7 N m (29 5 lb. ft). Half of the injectors and half of the valves can be adjusted at each top-dead- center (TDC) position of the crankshaft. Refer to the Service Manual procedure for "Fuel Timing".4. Stamp the new fuel timing specification of 64.16 mm on the new 4W5140 Information Plate. The plate is 'scored' lengthwise (to be easily broken lengthwise) so that only the part of the plate with new information can be applied over the original Engine Information Plate allowing the other information to remain showing (refer to Illustration 2). This plate has a self-stick adhesive on the back, which is exposed by removing the protective covering. The original engine information plate may be located on top of the valve cover, on the side of the engine between the governor and the fuel filter, or on the side of the engine on the rear side-cover..
