Field engines
Pump jacks, transfer pumps, and support engines that have to crank when the lease needs them, often on 24v.
Oilfield starter and alternator service from Lubbock
A&J Summit Ridge Holdings LLC works on oilfield starters and alternators at 3511 Avenue A in Lubbock. Crews from West Texas and Hobbs, NM bring units in from the field. There is no Hobbs storefront. Walk-in hours are Monday through Thursday, 9:30 AM to 5:00 PM. Friday is closed for regular walk-ins.
What comes in from the field
Oilfield starting and charging work is the same job as other heavy-duty units, with worse dirt, heat, vibration, and distance from a parts counter. These are the units we see.
Pumps and compressors
Stationary and trailer-mounted equipment whose starters and alternators live in dust and heat more than they sit in a shop.
Trucks and support gear
Service trucks, winch trucks, and yard equipment running 12v or 24v starting and charging systems.
West Texas
Units come in from the Permian and the rest of West Texas. The shop that does the work is in Lubbock.
Hobbs, NM
Hobbs crews bring starters and alternators to Avenue A. We do not have a Hobbs location. One bench, one address.
Not sure what it is?
Bring the complete starter or alternator, the machine it came off, and any readable label or casting numbers. We would rather look at it than have you guess.
24v oilfield starters and alternators
A lot of oilfield equipment is 24v, not 12v. That is a different system, and treating it like a car charging problem wastes time.
- 24v is two 12v batteries in series. A weak battery, a bad cable, or a poor ground can look like a dead starter.
- Cranking current is high. Big diesels pull hard. Contact condition, cable size, and connections matter more than they do on a pickup.
- Alternators see a hard life. Dust, heat, vibration, and long idle periods wear brushes, bearings, and regulators.
- Part numbers are often not in a retail lookup. Labels, casting numbers, and the unit itself are the identification. Bring them.
- We also work 6v and 12v. Older engines and mixed fleets show up the same way. Bring the unit and say which voltage if you know it.
A 24v no-crank is often the starter, the solenoid, the cables, or the batteries. Bring the starter or alternator so we can test the unit instead of swapping parts in the field. See also heavy-duty and industrial service and the troubleshooting guide.
What to bring with the unit
The unit itself is the best reference. Bring it to 3511 Avenue A, Lubbock, TX 79404.
- Equipment. Engine, pump, truck, or machine type, make, and model if you have it.
- System voltage. 12v or 24v, if you know it. 6v if that is what it is.
- Part details. Part number, label numbers, output rating, or casting numbers.
- The problem. No crank, slow crank, charging fault, noise, or a unit that failed more than once on the same machine.
- Where it came from. West Texas, Hobbs, or elsewhere. That does not change the bench work. It helps us know the application.
