2. Check the axial clearance of the compressor shaft.
Install the pointer indicator on the compressor side, move the turbine wheel by hand, measure the axial clearance. The axial clearance is no more than 0.11 mm.
If the axial clearance is outside the permissible limits, replace the turbocharger.
3. Check the radial clearance of the compressor shaft.
- a) Install the indicator on the compressor shaft through the turbocharger oil drain hole.
- b) Move the shaft in the radial direction and measure the radial clearance. Radial clearance: no more than 0.18 mm.
If the radial clearance is outside the permissible limits, replace the turbocharger.
4. Check the operation of the actuator drive.
(The official source is on the portal: «ToyotaMAN.ru»)
- a) Disconnect the actuator diaphragm hose.
- b) Create a pressure of approximately 1.09 bar above the diaphragm: the actuator stem should move and the valve should open.
Warning: Never apply more than 1.22 bar of pressure to the diaphragm.
