Severns Diesel provides mobile heavy-equipment and commercial diesel repair for contractors, equipment owners, and fleets across the region. Our experienced diesel technicians bring dealer-level diagnostics and fully equipped service trucks directly to your job site to keep your machines running and reduce downtime.
We bring the shop to your job site. Our fully equipped service trucks handle diagnostics and repairs on location, saving you the cost and downtime of hauling equipment. Common needs include machines that will not start, warning lights, leaks, or performance problems. We service excavators, loaders, dozers, skid steers, and other heavy equipment.
We use advanced dealer-level diagnostic software to read fault codes, monitor live data, and pinpoint problems accurately instead of guessing. This helps identify the true cause of warning lights, derates, no-start conditions, and intermittent faults. We diagnose construction equipment, commercial trucks, and diesel-powered machinery across multiple makes.
Modern equipment relies on complex wiring and CAN-bus communication networks. We trace shorts, open circuits, bad grounds, failed sensors, and communication faults that trigger warning lights and shutdowns. Typical symptoms include dead electronics, gauges that stop working, sensors reading incorrectly, and modules that will not communicate. We work on construction equipment and commercial diesel systems.
We diagnose and repair diesel engine and fuel-system problems, from hard starting and rough running to power loss, excessive smoke, and poor fuel economy. Work includes injectors, fuel pumps, filters, sensors, and related components. We service diesel engines in excavators, loaders, tractors, generators, and commercial trucks.
We diagnose and repair aftertreatment problems on modern diesel engines, including DEF, DPF, and SCR systems. Common symptoms include aftertreatment warning lights, forced regens, derates, and reduced power caused by faulty sensors, clogged filters, or system faults. We restore these systems to proper working order in accordance with the equipment manufacturer's design.
We diagnose and repair hydraulic problems that cause slow, weak, or erratic operation. This includes pumps, cylinders, valves, hoses, and fittings, along with leaks and overheating. Common symptoms include lifting problems, drifting cylinders, unusual noise, and loss of hydraulic power. We service excavators, loaders, backhoes, skid steers, and other hydraulic equipment.
Operator comfort matters, especially in Florida heat. We diagnose and repair air-conditioning problems in equipment cabs and commercial trucks, from weak cooling to systems that do not blow cold at all. Work includes leak checks, compressors, controls, and related components. We service A/C systems on heavy equipment and diesel trucks.
Regular preventive maintenance helps avoid costly breakdowns and extends equipment life. We perform on-site fluid and filter changes, inspections, and adjustments, and we identify leaks and worn components before they fail. Maintenance intervals can be tailored to how your equipment is used. We maintain construction equipment, diesel trucks, and industrial machinery.
We support contractors and equipment owners who run multiple machines and need to keep them working. Fleet maintenance includes scheduled on-site service, multi-machine visits, inspections, and service documentation to help you track each unit. We work with construction and contractor fleets, commercial diesel fleets, and equipment rental and industrial fleets.
Undercarriage wear affects traction, stability, and repair costs on tracked equipment. We inspect and service undercarriage components and address problems such as loose or worn tracks, damaged rollers and idlers, and abnormal wear. Common symptoms include squeaking, excessive track sag, and uneven movement. We service excavators, dozers, and compact track loaders.
We repair medium- and heavy-duty commercial diesel trucks alongside off-road equipment. Services include engine and fuel-system work, electrical and diagnostics, aftertreatment, air conditioning, and preventive maintenance. Common needs include warning lights, power loss, no-start conditions, and roadside-related failures. We help keep work trucks and service vehicles running.
