The genuine XCMG Cover with OEM number 800172723 is a precision-engineered protective housing manufactured for XCMG articulated dump trucks and heavy off-highway vehicles. This robust cover shields critical drivetrain components including transmission housings, final drive cases, and hydraulic pump access ports from debris, moisture, and impact damage.
The XCMG Cover 800172723 is manufactured using precision die-casting or heavy-gauge stamping to maintain exact flatness across the sealing surface. Warpage is limited to less than 0.1 mm over the entire flange, ensuring uniform gasket compression and leak-free sealing even under thermal cycling.
Unlike aftermarket covers that often use lower-grade materials, this genuine XCMG component meets original equipment metallurgical standards. Tensile strength exceeds 500 MPa for cast versions, while stamped steel covers feature zinc-aluminum-magnesium coating for superior edge corrosion resistance.
Drivetrain components often see rapid temperature changes from cold start to full operating load. The 800172723 cover is designed with integrated ribbing that distributes thermal expansion stresses evenly, preventing warping or cracking. Finite element analysis confirms a safety factor of 6:1 against yield at peak operating temperatures.
The included OEM gasket (sold separately or bundled) features a non-stick coating that allows easy removal during service. Contamination from dust and water is virtually eliminated when the cover is torqued to specification, extending oil and filter change intervals by up to 25%.
The OEM 800172723 cover is used not only on AD-series articulated dump trucks but also on XCMG’s wheel loader differentials and motor grader final drives. Standardizing on this single part number reduces inventory complexity and mis-ordering errors.
Always verify your machine’s serial number prefix before ordering – variants exist for left-hand and right-hand access ports. The 800172723 is the most common variant for main transmission side covers on AD60 and AD80 trucks produced after 2018.
Before installing the new cover 800172723, thoroughly clean both the cover flange and the mating housing surface using a non-abrasive scraper and brake cleaner. Remove all old gasket material – any residue can cause localized high spots and leaks.
Inspect the cover for any shipping damage, especially around bolt holes and the sealing lip. Apply a thin film of clean engine oil to the new gasket (if using a non-coated type) to prevent sticking. Position the gasket and cover, then hand-start all six bolts before torquing in a cross pattern to 45 Nm.
After 10 hours of operation, re-torque the bolts to account for gasket compression. Periodic inspection of the cover during oil changes is recommended – look for cracks, corrosion, or signs of impact damage. Replace any cover that shows deformation or thread damage.
Repeated over-torquing can distort the 800172723 cover’s bolt bosses, leading to uneven clamp load. Always use a calibrated torque wrench – never use impact guns. Corrosion at the gasket interface is another frequent issue; applying anti-seize to the bolts (not the gasket) helps future removal.
If the original cover is cracked due to rock impact, inspect the underlying housing for damage before installing a replacement. The genuine XCMG cover includes a reinforcement rib pattern that is often missing on aftermarket copies, making it 40% more resistant to impact fracture.
A failed or leaking cover can cause rapid oil loss, leading to catastrophic transmission or differential failure. Replacing a complete transmission costs upwards of $25,000, while the genuine cover 800172723 is a fraction of that. Proactive replacement every 8,000 hours is a low-cost insurance policy.
Fleet data shows that using genuine covers reduces unplanned downtime by 70% compared to welded repairs or non-OEM parts. The precision machining also eliminates the need for excessive sealant application, saving labor time during each service event.
Each XCMG Cover 800172723 is manufactured under strict ISO 9001:2015 and IATF 16949 certified processes. Random samples from every production batch undergo dimensional inspection, hardness testing, and salt spray exposure. Only components that pass all criteria receive the XCMG Genuine Parts label.
Counterfeit covers often have mismatched bolt hole tolerances, thinner material sections, and poor paint adhesion. Always purchase from authorized distributors and verify the holographic label. XCMG provides a 12-month warranty against manufacturing defects for this cover.
