Kenworth Truck Repair Service
Kenworth trucks are built for comfort and efficiency on long grades and in hot summers. At Britt’s Diesel, we keep them road-ready with brand-aware diagnostics, spec-correct parts, and clear communication. Whether you’re running regional haul, construction, or vocational duty, our goal is simple: less downtime, more uptime.
Diagnostics & Common Repairs
We don’t guess and swap. Our techs follow a test-first workflow to pinpoint the real fault, control costs, and prevent comebacks.
What we solve every week
- Low power, derates, frequent regens (DPF/DEF/SCR, NOx/DP/temp sensors, dosing, wiring)
- Electrical/CAN-bus issues: intermittent power loss, module faults, ground/voltage-drop problems
- Turbo/charge-air leaks, VGT/actuator concerns, boost and smoke/pressure testing
- Cooling & HVAC: overheating on grades, weak heat/AC, fan control, CAC efficiency
- Brakes & ABS, air system dryers/valves/lines, chambers and hoses
- Steering/suspension & driveline: u-joints, carrier bearings, wheel ends, seals, ride-height/alignments
- Leaks (oil/coolant/fuel) with root-cause confirmation, not just top-offs
We validate repairs with live-data logs, pressure/flow checks, and road tests—so the fix sticks.
Models & Powertrains We Service
Highway and vocational Kenworths including T680, T880 and regional builds powered by PACCAR (MX-13/MX-11), Cummins, or Detroit. We coordinate engine, transmission, and chassis work under one plan—one visit, one estimate, one result.
Major Repairs: Engines & Transmissions
When the job goes beyond routine service, we build a measured plan around your schedule and routes.
Engine overhauls & replacements
- Failure confirmation: compression/leak-down, injector balance/return, oil analysis, boost/cooling integrity
- In-frame/out-of-frame work: head, liners/pistons, bearings, oil pump, timing components, full gasket/seal kits, overhead set
- Aftertreatment integration: DPF cleaning/replacement, sensor calibration, EGR/DEF checks to avoid post-overhaul regens/derates
- Reman/long-block options when economics or downtime favor a swap
Transmissions (PACCAR TX series, Eaton Fuller manual/automated, Allison)
- Clutch wear assessment, actuator/solenoid and TCM diagnostics, software updates & adaptations
- Manual gearbox repairs (synchronizers, bearings, seals)
- Clutch/flywheel service and driveline refresh to protect rebuilt/new units
- Final adaptations and loaded road tests to spec
Preventive Maintenance & Fleets
Eastern Sierra grades and temps are hard on cooling and aftertreatment—PM matters. We tailor intervals to duty cycle, terrain, and climate.
PM coverage
- 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.
Compliance Support (BIT/DOT)
We prep Kenworth trucks to pass the first time: lighting, brakes, tires, leaks, steering/suspension, and documentation. If we find a deficiency, we correct it fast and provide clean records for audits and resale.

Yes—T680, T880 and vocational/regional builds with PACCAR MX-13/MX-11, plus Cummins and Detroit options. We coordinate engine, transmission, and chassis in one plan.
With a test-first workflow: live-data logs, CAN/voltage-drop checks, fuel pressure & restriction tests, CAC/boost leak and smoke tests, and DPF/DEF/NOx/temp sensor verification—followed by a road test on grade.
Absolutely—in-frame/out-of-frame overhauls, head/liners/pistons/bearings, timing sets, and reman long-block swaps when uptime/economics fit. Every job gets calibration, leak/boost checks, and load road-tests.
PACCAR TX-series, Eaton Fuller (manual/automated), and Allison. We diagnose actuators/solenoids/TCM, assess clutch wear, perform updates/adaptations, and handle clutch/flywheel & driveline refresh.
Duty-cycle PM programs (oil/filters, fuel, coolant, CAC efficiency, trans/axle fluids, brakes/air system, wheel ends, batteries) plus BIT/DOT prep, quick corrections, VIN-level records, PM calendars, and priority bays for fleets.
