YY10V00001F4 / YY10V00001F5 / YY10V00001F6 Hydraulic Main Pump | New Holland E115SR E135SR EH130 E130 E135SRLC Midi Excavator (Point-by-Point Description)

1. OEM Part Number & Equipment Matching
YY10V00001F4: Original factory pump for New Holland E115SR short-swing midi excavator; cross interchange with Kobelco SK115SR/SK115SRDZ excavator.
YY10V00001F5: Calibrated version exclusively for New Holland E130 / EH130 standard tail swing model, identical outer mounting dimension with F4 variant.
YY10V00001F6: Revised specification pump matched for New Holland E135SR / E135SRLC long-track short-radius excavator; compatible with Kobelco SK135SR / SK135SRLC series.
Core base model: Kawasaki K3V63DTP twin variable displacement piston pump, genuine Kawasaki KPM internal structure, shared hydraulic platform for New Holland & corresponding Kobelco mid-size excavators.
2. Core Technical Specifications
Structure: Twin tandem variable piston main pump + integrated built-in pilot charge gear pump, equipped with LS load sensing control + horsepower cut-off regulator assembled on pump housing.
Total combined displacement: Dual main pump total 126cc/rev, built-in pilot gear pump 16cc/rev matching machine pilot control circuit layout.
Rated main system working pressure: 32.5MPa; factory preset relief pressure 35MPa consistent with original machine hydraulic parameter setting.
Total rated system flow reaches 235L/min under engine rated 2200RPM, perfectly matched with Isuzu 4BG1T turbo diesel engine equipped on E115SR/E135SR series.
Total assembly weight approx 68kg; splined input shaft fits original engine flywheel housing without any chassis or piping modification.
3. Product Core Advantages
Strict 1:1 OEM casting dimension: bolt hole layout, oil port position, mounting flange and input shaft spline fully consistent with original pump for direct plug-and-play installation.
Optimized load-sensing control system lowers internal oil leakage, ensures stable synchronized movement of boom, arm, bucket and travel under heavy digging load without speed drop or hydraulic hunting.
Complete supporting repair spare parts in stock: overhaul seal kits, piston assemblies, valve plate, swash plate and standalone pilot gear pump available for partial maintenance replacement instead of full pump assembly swap.
Three part numbers share identical outer housing and installation size, only internal regulator pressure calibrated differently for respective machine models to simplify client spare part inventory management.
4. Packing & Global Delivery Information
Pre-shipment preparation: Input shaft coated with anti-rust grease, whole pump wrapped with moisture-proof plastic film then fixed inside solid export plywood crate to avoid damage during sea or air transit.
In-stock products arranged for shipment within 3–5 working days after order confirmation; genuine OEM original pump follows fixed production lead time schedule.
Multiple global delivery solutions available: international air express for small trial orders, LCL/FCL sea shipment for bulk purchase, overland truck transport for Southeast Asian clients.
5. Common Customer FAQ
Q: What is the core difference between F4/F5/F6 three part numbers?
A: Only internal regulator pressure preset value differs to match E115SR/E130/E135SR respective factory hydraulic tuning; external appearance and installation structure fully interchangeable.
Q: Can supply separate pilot gear pump individually?
A: Yes, independent pilot pump component can be provided separately for onsite partial overhaul repair.
Q: Cross fit for Kobelco excavator?
A: Fully interchangeable with Kobelco SK115SR, SK135SR, SK135SRLC series excavator as alternative OEM replacement part.
