Eustis once shipped citrus north from its packing houses, and the USDA ran a citrus disease research station here. Today it is a city of about 25,000 (2024 estimate) with Lake Technical College’s main campus on Kurt Street and offices of two electric utilities, SECO Energy and Duke Energy. Three state and US highways carry its truck traffic. RDI Power has no shop in Eustis, so our technicians come to you: to the yard, the job site or the shoulder where the truck stopped, with scan tools, parts and the equipment to repair it there when the job allows.
SR 19 north of Eustis toward the Ocala National Forest
SR 19 runs from SR 50 in Groveland through Tavares and Eustis and on into the Ocala National Forest. FDOT counts about 3,100 trucks a day on it near Eustis. A truck headed north toward the forest, or south toward Tavares, should be described by its direction and the nearest cross road, business or landmark, because “SR 19 near Eustis” covers a lot of ground.
If you are about to head north on SR 19 with a warning light already on, call before you go rather than after. A truck that limps into a lot in town is a far easier repair than one stopped on a shoulder miles up the road.
SR 44 and US 441 around Eustis
SR 44 carries about 4,470 trucks a day on the segment from US 441 to Waycross Avenue, 15.4 percent of its traffic, the highest truck share of the three highways through town. US 441 carries about 4,500 trucks a day near Eustis. Mid Florida Air Service Airport sits on SR 44 east of town and makes a useful landmark, as do the Lake Tech campus and the utility offices.
On-site work at Eustis yards and job sites
Eustis actively courts new building, offering construction incentive vouchers for multi-family, mixed-use and non-residential projects, with a larger voucher inside its downtown redevelopment area. Building sites, utility jobs and fleet yards all suit on-site repair. A dump truck, a service body or a crew pickup that quits at the work can be repaired there, and the crew keeps working instead of waiting on a wrecker.
The site needs firm, level ground beside the truck, room to walk all the way around it, and a clear path in for the service truck. If the truck is parked on soft ground or behind equipment, tell us when you call so the technician arrives ready for it.
Service bodies and bucket trucks that stop in Eustis
When a service body or bucket truck quits at a work site, the fault may well be in the chassis rather than the equipment: a no-start, a charging fault that drained the batteries while the PTO ran, a wiring fault that keeps the PTO from engaging, or an engine that derated after hours of idle. Our technicians work on the truck itself, the engine, electrical system, air brakes, cooling and fuel, and the diagnosis will show whether the fault is in the truck or in the body.
Eustis no-start calls: what the technician checks first
A diesel that will not start is either an electrical problem or a fuel and air problem, and the first test tells you which. If the engine does not crank, the technician load-tests the batteries, checks cable ends and grounds for corrosion and voltage drop, and tests the starter circuit. If it cranks but will not fire, the questions turn to fuel: is fuel reaching the high-pressure pump, is there air in the system after a filter change, is the fuel filter restricted, did water get past the separator.
Glow plugs are part of the picture too. Newer Power Stroke and Duramax engines still use glow plugs, and a failed plug or controller can make starts rough, especially after a cool night. Most of those problems can be fixed where the truck sits. Our glow plugs page covers that system in more detail.
Every repair ends with a digital inspection, with photos and technician notes, so you see what failed and what was replaced.
Eustis repairs that need the Brooksville bays
If the diagnosis on a Eustis job turns up an engine knock that points to internal damage, a transmission that will not engage or a clutch that has to come out, the truck needs a lift and a teardown. We will say so rather than start something at the roadside that should not be done there, and then work out the tow with you. The technician’s notes and photos travel with the truck, so the shop does not repeat the diagnosis. Every repair carries a labor warranty of 3 years or 36,000 miles.
Reach us at (352) 433-3800 Monday through Friday, 7:00 AM to 4:00 PM. Fleet customers have roadside coverage around the clock as part of RDI Fleet, and fleet maintenance in Eustis shows how that program runs here. East of town along US 441 and SR 44, see Mount Dora mobile diesel repair. The complete picture of on-site service is on mobile diesel repair.
