The genuine XCMG 805801470 Clamp D40 is a heavy-duty tube and hose clamp engineered specifically for XCMG GR series motor graders. This OEM clamp secures hydraulic hoses, steel tubes, and cable bundles to prevent chafing, vibration damage, and unwanted movement in demanding construction environments. Manufactured from premium-grade carbon steel with a robust zinc-plated finish, the 805801470 clamp provides a 40 mm clamping diameter (D40) and is designed to withstand extreme pressure spikes, temperature variations, and exposure to hydraulic fluids, mud, and road salts.
The 805801470 clamp features a two-piece construction with a durable rubber insert that protects the hose outer layer from abrasion. The clamp halves are secured with an M8 hex bolt, allowing adjustable clamping force and easy installation. This design is widely used on XCMG GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 motor graders for securing brake lines, steering hoses, and hydraulic supply lines to the frame and axle housings.
A missing or corroded clamp can lead to hose rubbing against sharp edges, resulting in premature hose failure, fluid leaks, and costly downtime. Replacing a worn or broken clamp with the genuine XCMG 805801470 restores proper routing and extends hydraulic system life. Keep your grader’s hoses securely mounted with this essential component.

The 805801470 Clamp D40 plays an essential role in protecting hydraulic hoses and tubes on XCMG motor graders. These hoses operate at pressures up to 35 MPa and are constantly subjected to vibration from the engine, drivetrain, and blade impacts. Without secure clamping, hoses can rub against sharp edges of the frame, leading to abrasion, pinhole leaks, or catastrophic bursts.
Typical applications include clamping the steering cylinder supply lines, brake hoses, differential lubrication tubes, and hydraulic oil cooler lines. The D40 size (40 mm) is specifically designed for common hose outer diameters used in XCMG GR series brake circuits and pilot lines. The integrated rubber insert dampens vibration and prevents metal-to-metal contact.
When the original clamp becomes corroded or the rubber deteriorates, the hose loses support and may sag, contacting hot engine components or moving suspension parts. Replacing a faulty clamp with genuine 805801470 restores original clearances and ensures safe, reliable operation. Regular inspection of all clamps during 500-hour service intervals is highly recommended.
XCMG engineers selected stamped carbon steel for the 805801470 clamp body, offering excellent strength-to-weight ratio and fatigue resistance. The stamping process ensures consistent geometry without stress risers. After forming, each clamp receives a thorough zinc plating followed by yellow chromate conversion, providing sacrificial corrosion protection even if the surface is scratched.
The rubber insert is molded from premium NBR (nitrile butadiene rubber), which resists swelling and degradation when exposed to hydraulic oil, diesel, grease, and common workshop chemicals. The insert features a ribbed inner surface that provides non-slip grip on smooth hose covers, preventing axial movement while allowing thermal expansion.
The M8 bolt and nut are zinc-plated and treated with a clear topcoat to prevent galling. Genuine XCMG clamps are tested for 500 hours of salt spray per ASTM B117, ensuring long life in coastal, winter road salt, or high-humidity environments where aftermarket clamps quickly rust and fail.
To replace a worn clamp, first clean the area around the hose to remove dirt and debris. Using a 13 mm socket or wrench, loosen the M8 bolt and separate the two halves. Remove the old clamp and inspect the hose for any signs of abrasion or cuts. If the hose is damaged, replace it before installing the new clamp.
Position the new 805801470 clamp around the hose with the rubber insert evenly seated. Align the mounting hole over the welded nut or threaded bracket on the grader frame. Insert the M8 bolt and tighten by hand until snug. Using a torque wrench, apply 15-18 Nm (11-13 ft-lb). Do not overtighten, as excessive torque can collapse the hose or deform the rubber insert.
After installation, ensure the hose has a slight amount of axial play (1-2 mm) to accommodate thermal expansion. The clamp should not pinch or twist the hose. For long hose runs, use multiple clamps spaced every 500-600 mm to prevent sagging. Keep spare 805801470 clamps in your service truck for on-site repairs.
Aftermarket clamps often use low-carbon steel that bends under load and lacks proper corrosion resistance. Many have rubber inserts made from low-grade PVC or recycled rubber that hardens, cracks, or dissolves in hydraulic oil within months. The genuine 805801470 uses NBR rubber tested for 3,000 hours of oil immersion without deterioration.
Counterfeit clamps may have misaligned bolt holes or incorrect D40 diameter (39 mm or 41 mm), causing either loose fit or excessive compression that restricts fluid flow. Genuine XCMG clamps are 100% dimensionally verified using laser gauging. The zinc finish on counterfeit parts often peels after 100 hours of salt spray, leading to rust that stains hose covers and weakens the clamp.
XCMG provides a 12-month warranty against manufacturing defects. Each genuine 805801470 clamp is marked with the XCMG logo or supplied in branded, tamper-evident packaging. Protect your grader’s hydraulic investment with authentic components – the cost of one hose failure far exceeds the price of a genuine clamp.
Signs that a clamp requires replacement include: rubber insert cracking or missing, visible rust on the metal body, bolt that spins without tightening, and hose movement more than 5 mm when pushed by hand. Also check for rust staining around the clamp – this indicates the zinc coating has failed and corrosion is active.
Preventive replacement is recommended every 2,500 operating hours or every 24 months in normal conditions. For graders operating in coastal areas or with daily road salt exposure, reduce interval to 1,500 hours. During each 500-hour service, visually inspect all clamps under the cab, along the frame rails, and near the articulation joint.
Keep a stock of 805801470 clamps in your parts inventory. A single clamp costs only a fraction of a replacement hydraulic hose plus labor and downtime. When you find one failing clamp, consider replacing all clamps in the same hydraulic circuit, as they likely have similar age and wear. Well-secured hoses last longer and reduce leak risks.
