WORKSHOP & FIELD CAPABILITY
Heavy Diesel Engine Diagnostics & Rebuilds
Modern heavy diesel engines require advanced OEM-level diagnostic software and deep mechanical precision. We test, diagnose, and rebuild engines down to factory tolerances.
✔ Engine Platforms: Cummins X15/ISX, Detroit DD15, CAT C15, Volvo D13/D16, Scania, Isuzu & Hino.
✔ Electronic Diagnostics: Active fault clearing, sensor calibration, injector balance testing, and live data logging.
✔ Rebuilds & Overhauls: Cylinder heads, turbos, oil coolers, water pumps, camshafts, and bottom-end bearings.
✔ Emissions Systems: DPF cleaning, EGR cooler testing, and SCR/AdBlue fault rectification.
TRANSMISSION & DRIVETRAIN
Clutch Replacements & Gearbox Overhauls
Heavy hauling takes a punishing toll on clutches, gearboxes, and differentials. We replace heavy clutches fast and rebuild gearboxes for long-haul reliability.
✔ Manual Gearboxes: Eaton Fuller Roadranger 9, 13, 15, and 18-speed transmission repairs.
✔ Automated Manuals (AMT): Volvo I-Shift, Mack mDRIVE, Scania Opticruise, and ZF TraXon servicing.

✔ Driveline: Tailshaft balancing, universal joints (U-joints), center support bearings, and differential repairs.
CRITICAL SAFETY SYSTEMS
Air Brake Relines, Airbags & Suspension
Nothing matters more than stopping power and stable ride geometry. We ensure your braking and suspension systems pass strict heavy vehicle roadworthy standards.
✔ Brake Relines: Heavy drum and disc brake pads, S-cam shafts, bushings, rollers, and automatic slack adjusters.
✔ Pneumatic Air Valves: Foot valves, relay valves, unloader valves, air dryers, and air tanks.
✔ Suspension Systems: Airbag replacements, height control leveling valves, leaf springs, and shock absorbers.
✔ Hydraulics: PTO units, tipping hydraulics, hoist rams, walking floor lines, and wet kit installations.
ALL COMBINATIONS & TRAILERS
Trailer Repairs, Turntables & Running Gear
Trailers endure continuous vibration, twisting, and heavy payloads. We maintain running gear so your trailers track true and pass inspection every time.
✔ Trailer Types: Semi-trailers, B-doubles, tippers, curtainsiders, tautliners, skeletal and flat-tops.
✔ Turntables & Kingpins: Ballrace turntables, Holland/Jost turntables, jaw kits, and kingpin replacement.
✔ Axles & Wheel Bearings: BPW, Hendrickson, York, K-Hitch bearing repack, adjustment, and hub seals.
✔ Body & Structure: Landing leg replacement, curtain rollers, tensioners, air plumbing, and LED lighting harnesses.
