GEK–91584D, V ertical Drilling Motor , T ype GE752 10 INSPECTION MONTHL Y Inspect the exterior of the machine, including cables, for damage. Covers, Seals, Latches Clean the outside of the machine and remove the in- spection covers. Use clean, dry compressed air and blow the dirt and carbon dust from the interior of the ma- chine.
V ertical Drilling Motor , T ype GE752, GEK–91584D 11 3. Continue tapping as described in Step 1 until the 0.753 dimension falls between 0.751 and 0.755. 4. If, due to excessive pounding, the inside dimen- sion becomes less than 0.751 in., file back to size with a fine mill file.
GEK–91584D, V ertical Drilling Motor , T ype GE752 12 Brushes Brush wear is determined by measuring actual brush length from the top of the carbon. Lift the brush spring, remove the brush and measure brush length on the longest side.
V ertical Drilling Motor , T ype GE752, GEK–91584D 13 Insulation Measure the insulation resistance with a meg– ohm- meter (Megger) to determine the condition of the insula- tion. If reading is low , make a further inspection to deter- mine if insulation failure or excessive moisture is caus- in g the low megohmmeter reading.
GEK–91584D, V ertical Drilling Motor , T ype GE752 14 3. Remove bolt, washer and brushholder clamp. Lift the brushholder out of the frame. Installation 1. Position the brushholder in the frame with the brushholder studs resting in the clamp surfaces of the brushholder support.

GEK–91584D, V ertical Drilling Motor , T ype GE752 16 CAUTION: Never use an emery cloth on this or any commutator . The abrasive particles on emery cloth scratch the commutator surface and lodge in the groves between commutator segments. The condition creates the possibil- ity of an eventual flashover which could seri- ously damage the machine.
