As shown in FIGS. 2 and 3 of the drawings, a first shaft and a second shaft extend from the motor unit 30 from opposing ends of the motor unit 30.

[0049] It is preferable to have a torque unit 64 attached to the shafts to limit the amount of torque allowed to be applied to the hub member 20 through the shafts as shown in FIG. 2 of the drawings. The torque unit 64 is preferably controlled by a torque control 62 within the covers 40, 50 wherein the torque control 62 is electrically connected to the battery unit 36 as shown in FIG. 9 of the drawings. The torque control 62 is preferably a switch structure that allows the operator to select the desired amount of torque limitation which will limit the pulling force upon the fish tape 24 and wire 14. For example the torque control 62 may allow limiting the amount of torque to between 2 to 90 foot-lbs. This prevents damage to the wire 14 being pulled through the conduit 12. The torque unit 64 simply slips when the torque exceeds the desired level.

[0050] A first gear 32 and a second gear 34 are attached to the first shaft and the second shaft of the motor unit 30 respectively for engaging opposing main gears 22 of the hub member 20 thereby rotating the hub member 20 in the desired direction. It can be appreciated that if the first shaft and the second shaft of the motor unit 30 rotate in opposite directions that the first gear 32 and the second gear 34 may be utilized upon a single main gear 22 of the hub member 20. A pair of disk members are preferably attached to the shafts of the motor unit 30 and are rotatably received within a slotted bracket within the first cover 40 and the second cover 50 as shown in FIGS. 2 and 3 of the drawings.

[0051] FIGS. 6 through 8 illustrate the usage of a guide tube 70 having at least one connecting slot 72 removably attachable to the first guide 46 and the second guide 56 of the covers 40, 50.
