Assemble Torque Divider (Power Shift)
NOTE: Before assembling the torque divider, a measurement of certain clearances must be made if the torque divider is to operate with efficiency.
1. Check the clearance between the turbine and stator as follows:
a) Put stator (3) in position in turbine (2). Hold the stator against one side of the turbine and use a feeler gauge (1) to find the clearance between the stator and the turbine.
b) The clearance across the diameters between the stator and the turbine must be .012 to .018 in. (0.30 to 0.46 mm). Check the clearance at four points on the turbine. The maximum permissible clearance across the diameters is .030 in. (0.76 mm).
c) The running clearance is one half of the clearance across the diameters between the stator and the turbine. The running clearance must be .006 to .009 in. (0.15 to 0.23 mm). The maximum permissible running clearance is .015 in. (0.38 mm).
2. Check the clearance between the impeller and stator as follows:
a) Using an outside diameter micrometer (4), make a measurement of the diameter of the stator flange at four points on stator. Make a record of the lowest reading.
b) Using an inside diameter micrometer (6), make a measurement of the inside diameter of outer edge of flange on impeller (5) at four points. Make a record of the highest reading.
c) The clearance across the diameters between the impeller and stator is the difference between the highest reading on impeller and the lowest reading on stator. The clearance must be .009 to .015 in. (0.23 to 0.38 mm). Maximum permissible clearance across the diameters is .024 in. (0.61 mm).
d) The running clearance is one half of the measurement made across the diameters. Running clearance must be .0045 in. to .0075 in. (0.114 to 0.191 mm). Maximum permissible running clearance is .012 in. (0.30 mm).
