Hino

Hino medium-duty trucks are daily workhorses for delivery and service fleets. At Britt’s Diesel, we keep them reliable with test-first diagnostics, spec-correct parts, and clear communication—so your trucks make every stop on time. Whether you run single units or a multi-truck route, our process is built for fast, durable fixes and clean documentation.

Diagnostics & Common Repairs

We don’t guess and replace. We verify the fault first to prevent repeat visits and parts roulette.

Issues we solve every week

• No-start / hard-start / rough running, limp mode, and low-power complaints
• Aftertreatment & regen faults (DPF/DEF/SCR), differential pressure/NOx/temp sensors, dosing issues, forced/stationary regens
• Fuel system testing: restriction, aeration, injector return, lift-pump and water-separator problems
• Turbo/charge-air leaks and boost control checks; smoke/pressure tests
• Cooling & HVAC: overheating on grades, fan clutch control, heater core and blend-door issues, CAC efficiency
• Oil/coolant leaks (gaskets, seals, coolers, water pumps) with root-cause confirmation
• Electrical & CAN-bus: chafed harnesses, ground/voltage-drop faults, intermittent module codes
• Brakes/ABS & air systems, steering/suspension wear, driveline vibration (u-joints, carrier bearings, wheel ends)

Repairs are validated with live-data logs, pressure/flow checks, and a short road test on grade before we hand back the keys.

Models & Engines We Service

Conventional and cab-over Hino platforms used throughout regional delivery:

• Cab-over: 155, 195 (gas/diesel), hybrid variants
• Conventional: 238, 258, 268, 338 and vocational bodies (box, reefer, dump, service, crane)
• Engines: J-series (e.g., J05E, J08E) and other spec’d powertrains
• Transmissions: Aisin and Allison automatics, plus clutch/flywheel and driveline service where equipped

We coordinate engine, transmission, and chassis work in one plan—one estimate, one timeline, one result.

Major Repairs: Engines & Transmissions

When a job moves beyond routine service, we scope it carefully and build around your route schedule.

Engine overhauls & replacements

• Failure confirmation: compression/leak-down, injector balance/return, oil analysis, boost/cooling integrity
• In-frame/out-of-frame work: cylinder head, liners/pistons, bearings, oil pump, timing components, full gasket/seal kits, overhead set
• Aftertreatment integration: DPF clean/replace, sensor calibration, EGR/DEF checks to avoid post-repair regens and derates
• Reman/long-block options when downtime or economics favor a swap
• Final validation: hot/cold starts, leak/boost checks, data logs, and on-grade road test

Transmissions & driveline

• Aisin/Allison service, adaptations/updates, cooler/line inspections
• Clutch/flywheel replacement (where applicable) and driveline refresh (u-joints, carrier bearings, seals)

PM Programs & Fleet Support

Eastern Sierra routes punish cooling and aftertreatment systems—PM matters. We tailor intervals to duty cycle, altitude, and temperature swings.

PM coverage includes

• Engine oil & filters matched to use case
• Fuel filtration & water separator service
• Coolant testing/exchange; hose/clamp and CAC efficiency checks
• Transmission/axle/PTO fluids to spec
• Brake/air-system and wheel-end inspections; torque/mount audits
• Battery/charging load tests and electrical integrity checks

Fleet customers get priority bays, VIN-level service history, PM calendars, consolidated invoicing, and proactive advisories to reduce cost-per-mile and prevent roadside events.

BIT/DOT Inspection Readiness

We prep Hino trucks to pass the first time. Our checklist covers lighting, brakes, tires, leaks, steering/suspension, and documentation. If we find a deficiency, we correct it quickly and provide clean records for audits and resale.
