Belangrijkste functies en voordelen<\/span><\/h3>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Precision\u2011remanufactured transfer case<\/span><\/strong><span class=\"\">\u00a0\u2013 OEM part number YB60000413. Fully disassembled, cleaned, crack\u2011inspected, and rebuilt with new bearings, seals, gaskets, and reconditioned gear surfaces. Restored to deliver power distribution performance matching original Hitachi specifications.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Critical power\u2011splitting component for 80\u201385\u2011ton excavators<\/span><\/strong><span class=\"\">\u00a0\u2013 The transfer case sits between the engine-driven hydraulic main pumps (typically the HPK300, OEM part number 9298854 \/ YB60000246 for these large models) and the pump drive gear train from the engine flywheel housing. Its job is to split engine torque to drive the dual hydraulic main pumps while also supplying power to auxiliary pump mounts, ensuring each pump receives the correct speed and torque for its hydraulic circuits. When the transfer case fails \u2013 due to bearing seizure, gear wear, seal leakage, or lubrication breakdown \u2013 the main pumps cannot operate, and the entire machine stops.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Restores 80\u2011ton class hydraulic power<\/span><\/strong><span class=\"\">\u00a0\u2013 Your ZAX870\u20115G or ZAX890\u20115A is a large excavator (approximately 80\u201385 metric tons, operating weight of the ZX870\u20115G is approx. 80,800\u201382,600 kg). The transfer case must reliably transmit the engine\u2019s full 360\u2013377 kW (483\u2013506 HP) to the hydraulic pumps without internal power loss. A rebuilt transfer case ensures full flow and pressure reach the main pumps \u2013 restoring original digging force, swing torque, and travel power.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">New bearings and high\u2011temperature seals<\/span><\/strong><span class=\"\">\u00a0\u2013 The most common failure points in these high\u2011hour transfer cases are bearing fatigue (from millions of stress cycles) and seal deterioration (leading to oil leaks, contamination ingress, and eventual gear damage). Every bearing is replaced \u2013 never reused. All seals and O\u2011rings are replaced with high\u2011temperature fluororubber (FKM) rated for heavy\u2011duty mining conditions.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Gear surfaces inspected and reconditioned as needed<\/span><\/strong><span class=\"\">\u00a0\u2013 Gear teeth are inspected for pitting, spalling, or uneven wear. Where possible, gears are reconditioned; badly worn gears are replaced with new OEM\u2011grade components. The reconditioned gear train runs quieter, with less vibration, and provides consistent torque splitting across both pump drive positions.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Cost\u2011effective alternative to new OEM<\/span><\/strong><span class=\"\">\u00a0\u2013 A new Hitachi transfer case for an 80\u2011ton excavator is a major capital expense. Our remanufactured YB60000413 gives you the same fit and function at a significantly lower cost, without compromising reliability. Each unit is tested before dispatch.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Direct bolt\u2011on replacement for ZAX870\u20115G \/ ZAX890\u20115A<\/span><\/strong><span class=\"\">\u00a0\u2013 Mounting flanges, drive splines, and port\/bolt patterns match original Hitachi dimensions exactly. No modifications, no adapters \u2013 your mechanic unbolts the old transfer case and bolts this one in.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Visuele verificatie voor verzending<\/span><\/strong><span class=\"\">\u00a0\u2013 Before packing, we send you clear, high\u2011resolution photographs of the actual remanufactured unit (mounting flanges, splines, gear housing, castings, overall condition). You approve shipment \u2013 we never ship blind.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Snelle levering<\/span><\/strong><span class=\"\">\u00a0\u2013 5\u20138 werkdagen vanuit ons magazijn in Guangzhou.

Toepassingen<\/span><\/h3>\n<p class=\"ds-markdown-paragraph\"><span class=\"\">The remanufactured Hitachi YB60000413 pump transfer case assembly is ideal for ZAX870\u20115G and ZAX890\u20115A excavators (and compatible ZX870\u20115G, ZX870LC\u20115G, ZX870H\u20115G, ZX870LCH\u20115G, ZX890\u20115A variants) used in high\u2011production environments:<\/span><\/p>\n<ul>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Grootschalige dagbouwmijnbouw<\/span><\/strong><span class=\"\">\u00a0\u2013 80\u201385\u2011ton excavators load haul trucks, clean mine faces, and maintain roads in 20+ hour shifts. The transfer case runs constantly under full engine load. A worn unit introduces power loss and heat, slowing cycle times. A remanufactured transfer case with new bearings and seals restores efficient power transmission \u2013 keeping the main pumps at full output, reducing fuel consumption, and preventing unexpected production stops.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Heavy civil &amp; infrastructure projects<\/span><\/strong><span class=\"\">\u00a0\u2013 Dam construction, highway cuts, tunnel portals, and large\u2011scale earthmoving demand consistent multi\u2011function hydraulic power. A failing transfer case starves the main pumps, causing sluggish boom response and slower cycle times. Our remanufactured unit restores original responsiveness.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Steengroeven &amp; toeslagmaterialen<\/span><\/strong><span class=\"\">\u00a0\u2013 Granite, limestone, and basalt operations subject the drivetrain to extreme shock loads and abrasive dust. The transfer case\u2019s reconditioned gear train and new sealing system resist contamination ingress \u2013 keeping the pump drive system clean and protected.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Onderhoud van materieelverhuurvloot<\/span><\/strong><span class=\"\">\u00a0\u2013 Large excavators are high\u2011value rental assets. A transfer case failure mid\u2011rental creates costly recovery logistics and customer complaints. A remanufactured unit offers predictable service life (3,000\u20135,000 hours) at a cost that makes proactive replacement financially sensible \u2013 avoiding expensive emergency repairs and downtime.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><strong><span class=\"\">Bosbouw en landontginning<\/span><\/strong><span class=\"\">\u00a0\u2013 Steep slopes, fallen timber, and hidden obstacles place uneven loads on the pump drive system. The transfer case must split torque reliably under fluctuating demand. A properly remanufactured unit with new bearings maintains smooth power delivery, preventing engine stall when load spikes occur.<\/span><\/p>\n<\/li>\n<\/ul>\n<h3><span class=\"\">3.
