a. the liquid directing unit having at least two compartments, one of said compartments having a liquid inlet opening and the other compartment having a liquid outlet opening therein, a turbine rotating spindle having means at its upper end to engage a rotatable drive shaft and means at its lower end to engage the central opening in the turbine, said spindle extending through both compartments, sealing means extending about the spindle and cooperating with the casing to prevent leakage of the liquid from either of the compartments;
b. said turbine rotating spindle being hollow from its end connected with the turbine to a point adjacent its opposite end, said spindle having an aperture in the area of the first-mentioned compartment for admitting liquid to the hollow spindle for directing the liquid into the opening in the hub of the turbine;
c. the other compartment having means for receiving the casing hub and means for sealing the hub within the said second-mentioned compartment;
d. said second-mentioned compartment having an outlet opening for said cleaning liquid.
6. An improved torque converter cleaning apparatus as claimed in claim 5 wherein the end of the spindle engaging the hollow opening in the turbine is of a cone-shaped form tapered inwardly toward its outer end for engaging a variety of sizes of openings in the turbine hub opening and having a single spline on the surface thereof to engage at least one of the grooves carried on the inner surface of the opening in the turbine for rotating the same.
7. A method of cleaning torque converters in which the torque converter is provided with a leak-proof liquid holding casing element having a single opening therein and an outwardly extending hollow hub surrounding said opening and attached to the outer surface of the casing for supporting said casing and an independently operatable turbine element positioned within said casing comprising, directing the cleaning liquid into the casing in the vicinity of the turbine, rotating at least one of the elements to swish the cleaning liquid about the turbine and the inner surface of the casing, and exhuasting the cleaning liquid from the casing through the previously mentioned opening in the casing and the hollow casing hub.
