(1) Cleaning Element Clean by blowing compressed air from inside. Replace the element if seriously clogged or broken. Do not hit the element against other object to remove dust. Do not blow air from outside.For periodic cleaning and replacement of the element, see Owner's Handbook.(2) Inspection of Dust Indicator Start the engine and close the inlet port of air cleaner gradually to increase negative pressure. If the red signal is displayed at the dust indicator, the dust indicator is normal.4-2 Turbocharger

For disassembly of parts with an encircled number, see following items.(1) Be sure to make alignment marks on the compressor cover, bearing housing, and turbine housing, as their positional relationship is extremely critical at reassembly. (2) Remove the coupling assembly to remove turbine housing. The compressor wheel and turbine wheel blades are easy to bend. Use care not to drop them or hit them against other objects. (3) Remove the snap ring Retain the snap ring by hand to prevent it from springing out when slipping off the snap ring pliers. (4) Using a plastic hammer, tap the compressor cover on its periphery and remove. Be careful not to hit the compressor wheel against compressor cover as its blades are easy to bend. (5) Removal of Compressor Wheel (a) Fit the bearing housing into the turbine housing which is clamped in a vise. Hold the bolt on shaft and turbine wheel and remove the lock nut that attaches the compressor wheel. (b) With the turbine wheel held by one hand, lightly turn the compressor wheel to remove it. (6) Remove the snap ring. Retain the snap ring by hand to prevent it from springing out when slipping off the snap ring pliers. (7) Removal of Insert, Oil Deflector, and Other Parts Using two screwdrivers, carefully remove the insert from the bearing housing. Then, remove parts shown in illustration. (8) Removal of Shaft and Turbine Wheel, and Bearing (a) Hald the shaft of turbine wheel and shaft by one hand and the bearing housing by the other hand, and carefully withdraw from the turbine housing.(b) Remove the parts shown in illustration from the bearing housing. 4-2-3 Cleaning and Inspection
(1) Cleaning Turbocharger manufacturers use a blasting equipment for cleaning parts at their workshop. As an alternative, effective method for overhaul at the dealer's workshop, use the following procedures. When a commercially-available neutral detergent is used for cleaning, make sure that it does not contain corrosive component.(a) Before cleaning, visually check the condition of parts. Check for burns, wear, and other defects which could not be identified after washing. (b) Immerse disassembled parts in a nonflammable solvent (Daido Kagaku Kogyo's Dai Cleaner T-30 or equivalent) to clean oily contamination. (c) Blow compressed air against the entire internal and external surfaces. (d) Using a plastic scraper or bristle brush, remove deposits from the surfaces. Then, dip parts in the nonflammable solvent and blow compressed air to them again. Use care to prevent damage to parts. (e) Apply clean engine oil to all sliding surfaces. (2) Inspection (a) Bearing housing Measure the I.D. of bearing hole.If the measurement exceeds the limit, replace the bearing housing.(b) Bearing Measure O.D., I.D., and length of the bearing.If the measurement exceeds the limit, replace the bearing (c) Shaft and turbine wheel 1) Measure O.D. of the shaft and turbine wheel journal. If the measurement exceeds the limit, replace the shaft and turbine wheel.Replace the piston ring with a new one. 2) Measurement of shaft bend Set a dial indicator just beside the threads on the shaft to measure bend.If the deflection of dial indicator exceeds the limit, replace the turbine wheel and shaft.If the shaft journal gets rough, hold the shaft between centers of a lathe, and polish the surface with a sand paper #400 and engine oil at a spindle speed of 300 to 600 rpm. Do not attempt to correct, but replace, a bent shaft. (d) Insert Measure the piston ring gap.Fit a new piston ring into the bore of the insert and measure the ring gap.If the ring gap is out of the specification, replace the insert.4-2-4 Reassembly
With the overhauled turbocharger mounted on the engine, crank the engine with starter to allow the engine oil to circulate through the turbocharger.(1) Installation of Shaft and Turbine Wheel, and Bearing 1. Apply engine oil to the piston ring and do not expand the ends when mounting it onto the turbine rotor.2. Do not apply excessive force to the turbine rotor during installation. After assembly, temporarily install the bearing housing to the turbine housing and temporarily secure with the coupling assembly. On TC05, install the bearing after temporary installation. Face the bearing end face with six oil holes to the compressor wheel. (2) Installation of Thrust Bearing Before installation, apply engine oil to the surfaces of thrust ring and thrust be
