Linhai Bighorn CUV LH400CUV-2 Service Repair Workshop Manual
VEHICLE/EQUIPMENT INTRODUCTION:
The Linhai Bighorn CUV LH400CUV-2 is a Chinese-manufactured compact side-by-side utility vehicle (UTV) designed for agricultural estates, hunting access, trail utility, and light work tasks. Linhai, based in Taizhou Zhejiang province of China, has been producing small engines and powersports vehicles since the late 1990s, building primarily on proven Japanese engine architectures and component designs. The Bighorn CUV platform features a liquid-cooled single-cylinder or twin-cylinder four-stroke engine of approximately 400cc displacement, housed in a compact tubular chassis with roll-over protection structure (ROPS), side-by-side seating for two, and a dump bed in the rear for cargo carrying.
The LH400CUV-2 variant represents a mid-size utility side-by-side that bridges the gap between compact ATVs and full-size UTVs like the Polaris Ranger or Kawasaki Mule. It features a CVT transmission with selectable high and low range, independent suspension at all four corners, hydraulic disc brakes, and a part-time four-wheel drive system with differential locking capability. The compact dimensions allow access through standard farm gates and into tight trails where larger machines cannot go, while the dump bed provides practical utility for hauling feed, firewood, tools, and harvested material. These machines are popular among small-acreage landowners, property managers, and outdoor enthusiasts who need reliable mechanical transportation across varied terrain.
SERVICE & REPAIR SCOPE:
- Engine cylinder head gasket replacement and valve adjustment
- CVT transmission belt replacement, variator face inspection, clutch shoe check
- Front and rear independent suspension ball joint and bushing replacement
- Differential gear oil change and seal replacement
- Brake pad replacement, caliper inspection, and brake fluid bleeding
- Steering rack and tie rod end service
- Engine oil change, oil filter replacement, and spark plug service
- Carburetor or EFI system diagnostics and fuel filter replacement
- Radiator flush and coolant replacement, thermostat testing
- Electrical system testing including stator, regulator, and ignition coil
- Winch installation wiring and solenoid diagnostics
- Roll cage and body panel removal/replacement
- Exhaust gasket replacement and muffler inspection
- Battery maintenance, charging system test, and fuse panel diagnostics
TECHNICAL SPECIFICATIONS:
- Engine: Approximately 400cc four-stroke, liquid-cooled
- Configuration: Single or twin-cylinder depending on sub-variant
- Transmission: CVT with H/L/N/R/P

DIAGNOSTIC INFORMATION:
- Engine will not start: check battery voltage (minimum 12V), verify spark at plug, test fuel delivery, inspect kill switch circuit, check neutral safety switch
- CVT belt shredding: inspect variator and clutch sheave for scoring, verify correct belt specification, check clutch engagement RPM, clean CVT housing of debris
- 4WD not engaging: test actuator solenoid, inspect front differential engagement mechanism, check 4WD switch voltage, examine wiring harness for rodent damage
- Brakes spongy or weak: bleed brake system, inspect pads for wear thickness, check rotor runout, verify master cylinder fluid is clean
- Engine overheating: flush radiator, check coolant level, verify fan operation, test thermostat opening temperature, inspect water pump flow
- Poor acceleration or bogging: clean or replace air filter, inspect spark plug condition, test fuel pressure, check CVT belt for wear/slippage
- Electrical component failure: check fuse panel, test battery condition under load, inspect ground connections, verify wiring harness integrity
