The present invention relates to directly measuring the torque applied to a capstan attached to an output shaft of a motor. The output shaft of the motor is rotatably mounted within a support. The motor includes a lever arm projecting therefrom. The lever arm coacts with a load cell to restrict the motor from rotating within the frame. As a torque is applied to the capstan, a proportional force is applied by the lever arm against the load cell. The force against the load cell can be calibrated to reflect the torque on the capstan.

A swivel includes two heads rotatably mounted to one another with a bearing arrangement including at least two angular contact bearings arranged to receive a tension loading, and one angular contact bearing arranged in an opposite direction to receive a compression loading. The swivel is attachable, such as with a clevis, to underground drilling equipment for use in pulling a cable or conduit during a widening operation. A calcium-based grease lubricates the bearings. Periodic flushing with calcium-based grease is through a grease zerk and two single lip seals. A separate center pin for mounting the inner races of the bearings is threadably mounted to one of the heads, wherein an unthreaded portion of the shaft is positioned in a counterbore in the head.
