Caution When disassembling, use care not to cause damage to the compressor wheel and turbine wheel blades. REMOVAL OF SNAP RING (1) Lay the unit with the compressor covers side facing down and using snap ring pliers. Remove the compressor cover attaching snap ring. Caution When removing the snap ring, hold it with fingers to prevent it from springing away.</p> <p>ENGINE Turbocharger SERVICE POINT OF DISASSEMBLY</p> <p>4</p> <p>REMOVAL ASSEMBLY (1)</p> <p>OF</p> <p>TURBINE</p> <p>WHEEL</p> <p>Remove</p> <p>the</p> <p>turbine</p> <p>wheel</p> <p>assembly, striking the circumference of the compressor cover with a plastic hammer. The turbine wheel assembly may be a little hard to remove due to an a-ring put on the outer circumference. CLEANING (1) Use clean cleaning oil commercially available. Do not use corrosive cleaning oils as they could cause damage to some parts. (2) Use a plastic scraper or hard brush to clean aluminum parts. INSPECTION TURBINE HOUSING (1) Check the housing for traces of contact with the turbine wheel cracks due to overheating, and other pitching, damage. deformation cracked. (2) Operate the waste gate valve lever manually to check that the gate can be opened and closed smoothly. ENGINE Turbocharger SERVICE POINT OF DISASSEMBLY</p> <p>Replace with a new turbine housing if</p> <p>5</p> <p>NOTE: COMPRESSOR COVER (1) Check the compressor cover for traces of contact with the compressor wheel and other damage. TURBINE WHEEL ASSEMBLY (1) Check the turbine and compressor wheel blades for bend. Burr damage corrosion and traces of contact on the backside and replace if defective. (2) Check the oil passage of the turbine wheel assembly for deposit and clogging. (3) Check the turbine wheel and compressor wheel for light and smooth turning. OIL PIPE Oil RETURN PIPE (1) Correct or replace the oil pipe and oil return pipe if clogged, collapsed, deformed or otherwise damaged. SERVICE POINTS OF REASSEMBLY INSTALLATION OF O-RING (1) Apply a light coat of engine oil to a new a-ring and fit in the turbine wheel assembly groove. Caution: When installing the O.Ring, use care not to damage it. A damaged O-ring causes oil leaks.

(1) Remove the hose that is connected to the fuel injection pump boost compensator and install the pressure gauge via the T -joint, as shown in the illustration. (2) Accelerate the vehicle in second gear with the throttle fully open, and take a reading of the measurement value on the pressure gauge when the engine speed reaches approximately 3,000 r/min. (3) If the pressure is not positive pressure, the reason is probably one of the following, so carry out the following inspection. Waste gate actuator is defective Leaking turbo pressure Turbocharger is defective make reading of the measurement values on the pressure</p> <p>(4) If the turbo pressure is 83 kPa (0.83 kg/cm2, 12 psi.), the reason is probably an abnormality in the turbo pressure control, so carry out the following inspection. Waste gate actuator rubber hose is disconnected or burst Waste gate actuator is defective Waste gate valve is defective ENGINE Turbocharger SERVICE ADJUSTMENT PROCEDURE 9</p> <p>WASTE GATE ACTUATOR INSPECTION INSPECTION (1) Connect a hand pump (pressurization type) to the nipple. (2) While gradually increasing the</p> <p>pressure, check the pressure where the waste gate actuator rod begins to move [approx. 1 mm (0.04 in.) stroke) Standard value: 91 kPa( 0.91 kg/cm2, 13 psi.) Caution To prevent damage to the diaphragm, do not apply pressure more than 104 kPa (1.04 kg/cm2, 15 psi.) (3) If the value is widely outside the standard value. Inspect the actuator or the waste gate valve, and replace if necessary.</p> <p>ENGINE Turbocharger REMOVAL AND INSTALLATION</p> <p>10</p> <p>Removal Steps1. 2. 3. 4. 5.
