초록

A torque converter may be inspected and verified using non-destructive testing methods so that the torque converter may be reused in a remanufacturing operation. The methods will permit a torque converter to be verified without needing to cut open the torque converter's housing to perform a close visual inspection. Rather, the methods make non-destructive inspection and verification possible.

청구항

We claim: 1. A method of inspecting a torque converter comprising: conducting a dynamometer test to verify the rate of engagement of a lock-up clutch in the torque converter; and conducting a fluid contamination test to determine the number of particles in fluid that is leaving the torque converter during the dynamometer test. 2. A method according to claim 1 further comprising: using results of the dynamometer test and results of the fluid contamination test to help determine whether the torque converter can be reused without performing any destruct...
