860615501 gear housing assembly for XCMG XMR603VT Light Roller

Short Description:

860615501 gear housing assembly is an original factory transmission protection and bearing structural component for XCMG XMR603VT light combination roller. Serving as the outer enclosure base of the gear transmission mechanism, it provides installation positioning, rigid support and closed‑space protection for internal gears, bearings and transmission shafts. This assembly bears alternating mechanical loads during power transmission, keeps internal transmission parts in accurate relative positions, stores transmission lubricating oil, and blocks external dust, gravel and splash‑on impurities. It stabilizes the gear meshing operating environment and guarantees reliable power transfer for the roller under frequent start‑stop and variable‑load compaction conditions.

description

The 860615501 gear housing assembly is developed according to XMR603VT roller transmission torque parameters and whole‑machine layout requirements. Adopting high‑strength integral casting technology, the housing features precise bearing seat holes, positioning reference surfaces, oil storage cavity and oil passage structures. Each mounting flange and connecting lug is machined to high tolerance standards, ensuring coaxiality and parallelism of internal gear sets after assembly. Reasonable oil‑holding cavity design realizes splash lubrication for gear pairs and bearing positions, reducing friction heat and wear of transmission components.

Road rollers are subjected to continuous vibration, impact load and torque fluctuation in site operation. Non‑standard replacement gear housings often suffer from insufficient housing rigidity, inaccurate bearing hole position, poor sealing surface flatness and unreasonable cavity structure. Long‑time operation may cause gear meshing deviation, abnormal transmission noise, local overheating, oil leakage and accelerated bearing failure. The genuine 860615501 gear housing assembly undergoes strict stress relief treatment and precision machining. It maintains stable dimensional accuracy under alternating load and vibration, keeps gear‑pair meshing state normal, reduces transmission system failure risks, and extends the service life of internal transmission parts.

advantages

• High‑strength cast housing with stress‑relief treatment reduces structural deformation risk under alternating torque and impact load, keeping bearing‑hole position stable.

• High‑precision machined bearing seats guarantee good gear‑pair meshing, lower transmission noise and reduce abnormal wear of gear teeth and bearings.

• Optimized internal cavity layout realizes effective splash lubrication and heat diffusion, avoiding local high‑temperature accumulation inside the gear housing.

• High‑flatness sealing mating faces cooperate with high‑quality gaskets to achieve good sealing effect and prevent lubricant leakage and dust ingress.

• Reasonable ventilation structure balances internal‑external pressure difference, effectively avoids oil‑splash overflow caused by pressure build‑up inside the chamber.

• Original‑factory positioning benchmark matches XMR603VT transmission assembly perfectly, with accurate installation size and excellent interchangeability for overhaul maintenance.

maintenance & replacement tips

• Regularly inspect housing surface for cracks, impact deformation and oil seepage at sealing positions to find hidden dangers early.

• Check tightening torque of mounting bolts periodically, prevent bolt loosening caused by long‑term vibration leading to sealing failure and oil leakage.

• Observe transmission noise and temperature rise during operation; abnormal noise or excessive temperature rise may indicate housing deformation or internal‑part damage.

• Strictly follow maintenance cycle to replace transmission lubricant, keep oil liquid clean and reduce abrasive wear inside the gear housing.

• Avoid violent impact on gear housing during construction and transportation to prevent permanent deformation of bearing‑seat holes.

• Select genuine 860615501 gear housing assembly for replacement during transmission‑system overhaul, restore original assembly accuracy and sealing performance.
