Turbocharger Disassembly - New Holland LS160 Manual

Inspection Before Disassembly
Visually check the running clearances of the turbine
and blower wheels for evidence of contact between
the vanes and casing. Spin the rotor by hand to see
if it rotates smoothly.
Check for turbine fin and housing clearance, intake
and exhaust.
Check to ensure the rotor and shaft turns smoothly
with no bearing roughness or binding.
Using a dial indicator, measure the end play
movement of the turbine and shaft,1, by placing a dial
indicator on the end of the shaft at 2.
End Play Movement
0.001" - 0.002"
Standard:
0.0035"
Allowable Limit:
Check the radial movement in the turbine shaft by
placing a dial indicator through the oil outlet in the
turbo housing at, 1. Move the right and left side of the
turbine shaft toward the radial, 2, simultaneously and
take a reading.
Radial Movement
0.003" - 0.005"
Standard:
0.0067"
Allowable Limit:
Disassembly
NOTE: Before separating the casings (turbine,
bearing and blower), be sure to mark across each
component and seam so they will be joined together
in proper sequence.
1. Remove the waste gate controller assembly, 1.
This can be accomplished with compressed air
of about 14 PSI (1 kgf/cm) applied to the control
air inlet at 2.
