1.
There must be a minimum radial (running)
clearance between the inside diameter of the
rotating housing and turbine.
2.
Check
the
clearance
between
the
inside
diameter of the rotating housing and the turbine
as follows:
a)
Install tooling (A) in four positions in the
rotating housing as shown.
b)
Put the rotating housing on a smooth flat
surface. Install turbine (1) in the housing.
c)
Put tooling (B) in the position shown.
d)
Push turbine (1) toward tooling (B) until it
makes contact with the inside diameter of
the rotating housing. Adjust the dial
indicator until it is on zero. Slide the
turbine 180° away from tooling (B) until it
makes contact with the other side of the
rotating housing. Make a record of the
dimension measured.
e)
Make this check at several locations
around the housing. Make a record of
each of the dimensions measured. The
largest dimension measured is used for
the clearance between the two parts. The
total clearance measured across the
diameters must be .020 to .040 in. (0.51
to 1.02 mm) with a maximum permissible
clearance of .045 in. (1.14 mm). The
radial (running) clearance is half of the
dimensions measured.
