The 803202737 Level Gauge is a genuine XCMG fluid level indicator designed for GR series motor grader hydraulic tanks, fuel tanks, and coolant reservoirs. This precision sight gauge allows operators to quickly verify fluid levels, preventing costly damage from low oil or fuel starvation. The 803202737 level gauge features a transparent acrylic tube with high-contrast markings, a protective metal guard, and a durable rubber seal. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining proper fluid levels, preventing aeration, and avoiding catastrophic equipment failure on GR series graders.
The 803202737 Level Gauge is manufactured to OEM specifications, with a center distance of 200 mm between mounting holes and a total length of 250 mm. The sight tube has a clear acrylic body with temperature-resistant properties, capable of withstanding up to 100°C continuous operation. The scale is marked in liters and percentage, allowing quick visual reference. As a genuine XCMG part, it matches the original mounting hole pattern, thread size (M10), and sealing gasket exactly.
Engineered for extreme durability, the 803202737 Level Gauge has an operating temperature range of -40°C to +100°C and is resistant to diesel, hydraulic oil, engine oil, and coolant. The acrylic tube is UV-stabilized to prevent yellowing and cracking. The steel guard is powder-coated black for corrosion resistance. Each gauge is 100% leak-tested at 1.5 bar and inspected for clarity and scale accuracy. Using genuine XCMG level gauges prevents fluid loss, overfilling, and operator errors caused by unclear or damaged gauges.

Genuine XCMG level gauge is essential for daily fluid checks and safe machine operation. Its robust construction and clear visibility outlast generic alternatives, ensuring operators can always monitor fluid levels accurately.
Aftermarket level gauges often use low-quality acrylic that becomes cloudy or cracks under UV exposure, or they have inaccurate markings. The genuine 803202737 Level Gauge from XCMG features UV-stabilized acrylic and precision-printed scales. Independent tests show that OEM gauges remain clear and readable for over 5,000 hours of sunlight exposure, while generic gauges become opaque after 1,000 hours. This reliability ensures operators can always see the true fluid level, preventing costly dry-running damage.
Each 803202737 Level Gauge is traceable to its production batch, with records of leak testing and scale accuracy verification. The gauge body is stamped with the XCMG part number for easy identification. XCMG’s quality control includes 100% pressure decay testing and optical inspection for clarity. Only gauges that meet all specifications are shipped, ensuring a perfect fit and long service life.
Installing the 803202737 Level Gauge requires draining the fluid below the mounting holes. Remove the old gauge and clean the sealing surface. Apply a new gasket (supplied) and position the gauge. Insert the M10 bolts and tighten to 15 Nm. Do not overtighten, as this can crack the acrylic tube. Refill the tank and check for leaks. Verify the fluid level appears within the scale range.
Inspect the 803202737 Level Gauge every 500 hours for cracks, cloudiness, or leaks. If the tube becomes discolored or the markings fade, replace the gauge immediately. Clean the exterior with a soft cloth and mild soap; avoid abrasive cleaners or solvents. Store spare gauges in a cool, dark place. Keep a spare gauge in your parts inventory, as a failed level gauge can lead to undetected low fluid levels and severe damage.
A cracked or cloudy level gauge prevents operators from accurately checking fluid levels, leading to low oil conditions that destroy pumps and bearings. The genuine 803202737 Level Gauge restores clear visibility, allowing quick and accurate fluid checks. Operators report fewer overfill spills and less dry-running damage after replacing old gauges. The protective steel guard also prevents accidental breakage from tools or debris.
In a fleet study of 20 XCMG GR215 graders, those equipped with genuine 803202737 Level Gauges had 90% fewer fluid level-related incidents over 4,000 hours compared to machines with aftermarket gauges. The improved visibility also reduced daily inspection time by 30 seconds per machine. For contractors who value uptime and preventive maintenance, an OEM level gauge is a simple but critical tool.
XCMG’s gauge plant uses precision molding and automated assembly to produce the 803202737 Level Gauge with consistent quality. The acrylic tubes are extruded and cut to length, then annealed to relieve internal stress. The steel guard is stamped and powder-coated. The scale is screen-printed with UV-cured ink for durability. Each gauge is assembled with new gaskets and tested on a pressure decay tester at 2 bar for 30 seconds. Random samples are subjected to thermal shock testing from -40°C to +100°C.
All 803202737 Level Gauges are individually packed in foam-lined boxes with spare gaskets. Bulk orders of 10 or more are shipped in cartons. XCMG’s global distribution centers maintain stock of this common replacement part, with same-day shipping available for urgent orders. For fleet operators, consignment stock and quick-ship programs are available via the contact buttons above.
The 803202737 Level Gauge directly replaces original part numbers 803202736 and 803202738. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders with factory hydraulic tanks. This gauge is used on the hydraulic reservoir, fuel tank, and coolant expansion tank. For a shorter gauge (150mm center distance), use part 803202739. Always verify the mounting hole spacing before ordering.
When replacing a gauge, also order new mounting bolts (part 803202740) and gaskets (803202741) if needed. XCMG recommends replacing the gauge every 5,000 hours or at the first sign of cloudiness. Keep one spare 803202737 Level Gauge in your service truck for quick replacement. For fleet operators, bulk orders of 10 or more include a 10% discount and free shipping.
For custom scales (e.g., marked for specific tank shapes) or alternative materials (e.g., polycarbonate for extreme impact resistance), use the buttons above to contact our technical sales team. Always provide your grader’s serial number and a photo of the existing gauge when ordering the 803202737 Level Gauge to ensure perfect fitment.
