Common questions
The questions we get asked most often, answered plainly.
Do you rebuild starters?
Yes. Starter rebuild support is one of our core services. A rebuild is a teardown and inspection with the worn parts replaced, covering the solenoid, brushes, starter drive, and bushings, for 6v, 12v, and 24v units. More on starter rebuilds.
Do you rebuild alternators?
Yes. Most alternator failures come down to a handful of wear parts, so a rebuild covers the brushes, slip rings, rectifier, voltage regulator, and bearings, with the rotor and stator tested before reassembly. More on alternator rebuilds.
Can I bring in a unit for testing?
Yes. Testing is part of what we do. Bring the unit to 3511 Avenue A, Lubbock, TX 79404 during walk-in hours, Monday through Thursday, 9:30 AM to 5:00 PM. Friday is closed for regular hours, so call 806-407-5227 ahead of time.
What information should I include to get a quote?
Vehicle or equipment details, the part number or any label and casting numbers, and a short description of the problem. Photos of the unit and its label answer most remaining questions on their own.
Do you work on heavy-duty, farm, truck, oilfield, or industrial units?
Yes. Industrial, agricultural, trucking, oilfield, and transit equipment is the core of what we do, covering 6v, 12v, and 24v starters and alternators. More on heavy-duty service.
