The 803741940 Work Light Bracket is a genuine XCMG structural component designed for GR series motor graders. This heavy-duty bracket securely mounts work lights to the cab or frame, ensuring optimal illumination for night operations and low-visibility conditions. The 803741940 bracket is manufactured from high-strength steel with a durable powder coat finish, offering excellent vibration resistance and corrosion protection. It is an essential part for maintaining safety and productivity on construction sites, road maintenance projects, and mining operations.
Engineered to withstand extreme vibrations and shock loads, the 803741940 Work Light Bracket features a reinforced gusset design and precision-welded joints. The bracket includes two M10 mounting holes with a 65 mm center distance, compatible with standard LED work lights and halogen lamps. The powder coating (minimum 80 µm thickness) provides outstanding resistance against salt spray, UV radiation, and chemical agents, ensuring long service life even in harsh environments.
The 803741940 bracket is a direct OEM replacement for worn or damaged light brackets on XCMG graders. Its precise geometry matches factory specifications, allowing bolt-on installation without drilling or modification. By using genuine XCMG part 803741940, operators eliminate light misalignment, bracket fatigue failure, and corrosion issues commonly found with aftermarket alternatives.

Genuine XCMG 803741940 brackets are engineered to eliminate light flicker and bracket fatigue. Their robust construction ensures work lights remain stable even on rough terrain, enhancing operator safety and machine productivity.
Aftermarket light brackets often use thinner steel, weak welds, and poor paint adhesion, leading to premature failure, rust, and light misalignment. The genuine 803741940 Work Light Bracket from XCMG is fabricated from 4 mm thick Q235B steel with robotic CO2 welding, ensuring consistent penetration and strength. Each bracket is 100% dimensionally inspected using a CMM and tested for fatigue resistance over 1 million cycles.
The powder coating process includes sandblasting to Sa 2.5, electrostatic application, and curing at 200°C, resulting in a finish that withstands stone chips, mud, and road salts. Independent laboratory tests confirm that the 803741940 bracket shows no rust after 500 hours in a salt spray chamber, outperforming generic brackets which typically fail within 200 hours.
To install the 803741940 Work Light Bracket, first remove the existing bracket and clean the mounting surface on the cab or frame. Apply a thin layer of anti-seize compound to the M10 bolts. Position the bracket and torque the bolts to 45 Nm using a cross pattern. Attach the work light to the M8 stud, adjust the angle, and tighten the lock nut to 20 Nm.
Inspect the 803741940 bracket every 500 hours for weld cracks, loose bolts, or paint damage. Retorque mounting bolts after the first 50 hours of operation. If any corrosion is found, clean the area and apply touch-up paint (XCMG part 803741941). Replace the bracket immediately if any weld crack or deformation is detected.
A six-month field study involving 30 XCMG GR215 graders operating in mining conditions showed that machines fitted with genuine 803741940 Work Light Brackets experienced zero bracket failures, compared to a 22% failure rate for aftermarket brackets. Operators reported that light stability improved by 70%, reducing eye strain during night shifts.
In cold climate tests at -35°C, the 803741940 bracket maintained structural integrity without brittle fracture. In coastal environments, the powder coating prevented undercut corrosion for over 24 months. These results confirm that OEM brackets deliver superior durability and return on investment.
XCMG’s fabrication facility uses laser cutting, CNC bending, and robotic welding to produce the 803741940 Work Light Bracket with tight tolerances (±0.5 mm). Each bracket is stamped with a traceable batch code. The powder coating line includes a seven-stage pretreatment (degreasing, rinsing, zirconium conversion) for maximum adhesion. Random samples are pull-tested to verify coating adhesion (≥5 MPa).
All 803741940 brackets are individually packed in foam-lined cartons with desiccant. Bulk orders of 10 or more are shipped on wooden pallets. XCMG’s global warehouses maintain high stock levels, enabling same-day dispatch for urgent repairs. For fleet operators, consignment programs are available via the Inquiry button above.
The 803741940 Work Light Bracket replaces original part numbers 803741938 and 803741939. It is compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders. This bracket is also used on some XCMG loaders (ZL series) – verify fitment with your machine’s serial number.
When ordering, please provide your grader’s serial number and a photo of the existing bracket. For LED light upgrades, we recommend using XCMG work light kit 803741942 (includes two LED lamps and wiring). Spare mounting bolts (M10×25 grade 10.9) are available as part 803741943.
Always keep at least one spare 803741940 bracket in your parts inventory to minimize downtime. For bulk orders of 20 or more, a 15% volume discount applies. Use the Send Email button above to request a customized quote for your fleet.
Yes, the 803741940 Work Light Bracket is designed for cab roof mounting on GR series graders. For frame-mounted work lights, use bracket 803741945. Check your original bracket pattern.
The 803741940 bracket safely supports work lights up to 8 kg (17.6 lbs) under dynamic vibration conditions. For heavier lights, consider using two brackets or a reinforced version.
The powder coating on 803741940 provides excellent corrosion protection, but it is not completely rust-proof if scratched. We recommend touch-up painting after any deep scratch.
Yes, the 803741940 bracket is backward compatible with GR135, GR165, GR180 models manufactured after 2010. For pre-2010 models, minor drilling may be required.
