Your heavy-duty rig is a versatile workhorse, capable of far more than just hauling freight from point A to point B. However, powerful as your main engine is, it isn’t designed or efficient for powering all the crucial secondary functions your truck needs to perform. This is where Auxiliary Power Units (APUs) and specialized power systems come into play. Your truck relies on these reliable auxiliary power sources to run essential secondary functions, and in turn, these systems need quality parts and dependable service to keep them operating at their peak.
Whether you’re in need of robust commercial Power Take Off (PTO) units to drive hydraulic equipment, or require expert hydraulic pump repair, you can confidently rely on Betts Truck Parts & Service to provide the specialized parts and expert service your truck or trailer requires.
What Functions Do Auxiliary Power Systems Support?
Auxiliary power systems are critical for a wide range of applications in the commercial trucking industry, including:
- Hydraulic Operations: PTOs are essential for powering hydraulic pumps, which in turn operate dump beds, lift gates, walking floors, cranes, product pumps (for liquid/bulk transport), and other specialized equipment
- Electrical Needs: Some APU systems provide electrical power to run sleeper cab HVAC (heating, ventilation, and air conditioning), in-cab appliances, and charge batteries without idling the main engine, saving fuel and reducing wear.
- Pneumatic Systems: Certain specialized trailers or equipment might utilize PTO-driven air compressors.
- Starting Power: The truck’s starter motor and battery system are fundamental auxiliary electrical components.
Failure in any of these systems can lead to significant operational disruptions, costly downtime, and reduced productivity.
Recognizing When Your APU or Power Components Need Attention
Proactive maintenance is key, but also be aware of warning signs:
- PTO Issues: Difficulty engaging or disengaging, unusual noises (grinding, whining), leaks, or inability to power equipment
- Hydraulic Problems: Slow or weak hydraulic operation, leaks from pumps, hoses, or cylinders, overheating hydraulic fluid, or noisy pump operation.
- Wet Kit Malfunctions: Issues with fluid flow, pressure problems, or leaks within the wet kit system.
- Starting Difficulties: Slow engine crank, clicking sounds when trying to start, or complete failure to start, indicating issues with the [[truck starter | Starter & Alternator Parts Page]] or battery system.
- Electrical Faults: Dimming lights, battery draining quickly, or issues with APU-powered accessories.
Addressing these symptoms promptly with professional diagnostics and quality replacement parts can prevent more extensive and expensive repairs down the line.
