Every hour your Kubota loader or tractor sits idle due to cooling failure costs hundreds — sometimes thousands — in lost productivity and repair labor. Counterfeit water pumps fail within weeks, causing sudden overheating, cylinder head warping, or even catastrophic engine seizure. OEM replacements take 3–4 weeks to arrive, halting critical jobs on construction sites or farms. And sourcing compatible parts across multiple Kubota models — from SVL75 loaders to M6040 tractors — often means juggling five different suppliers.
This water pump 1G772-73032 is engineered as a direct replacement for Kubota V3307, V3307-DI, and V3307T engines — built by ISO-certified factories with strict incoming material inspection and 100% pre-shipment performance testing. We’ve supplied over 12,000 units to fleet operators and repair centers across North America, Europe, and Southeast Asia since 2019. Whether you’re servicing a Kubota SVL75 loader on a tight demolition schedule or rebuilding an M6040 tractor’s cooling system before planting season, this part delivers consistent flow rate and pressure stability under continuous load.
This water pump operates reliably in high-duty-cycle environments: earthmoving on mining haul roads, precision grading at municipal infrastructure projects, port-side material handling under humid salt-air conditions, and long-haul agricultural operations across temperature extremes from -15°C to +45°C. In these settings, consistent coolant circulation prevents thermal stress buildup in the V3307 block — especially during extended idling or high-torque PTO operation. Kubota water pump 1G772-73032 ensures uninterrupted heat dissipation where downtime directly impacts contract deadlines and equipment utilization rates.
The impeller is precision-cast from high-silicon aluminum alloy (A380), maintaining dimensional stability after 5,000+ hours of continuous rotation at 2,800 rpm. The mechanical seal uses carbon-ceramic faces with Viton elastomers — rated for coolant temperatures up to 120°C and resistant to ethylene glycol degradation. Shaft runout is held to ≤0.05 mm per DIN 42955, ensuring minimal bearing wear and zero vibration-induced gasket leakage. Housing tolerances match original Kubota specifications ±0.02 mm, guaranteeing bolt-hole alignment and perfect gasket seating without shimming. Surface finish on the mounting face meets Ra 1.6 μm, preventing micro-leak paths that cause gradual coolant loss and air ingestion into the system.
A $45 counterfeit pump may save $20 upfront — but risks $1,800 in labor to replace warped cylinder heads, $3,200 in tow fees and rental replacement costs, and $12,000+ in delayed project penalties. OEM-spec cooling performance isn’t optional: undersized flow or poor seal integrity causes localized hot spots exceeding 220°C, accelerating liner cavitation and reducing engine life by 35–40%. Our water pump 1G772-73032 meets ISO 5801 volumetric flow standards and Kubota’s published pressure curve at 1,500–2,800 rpm — delivering true total cost of ownership (TCO) control through predictable service intervals and zero unscheduled downtime.
We source exclusively from ISO 9001-certified factories and perform incoming batch inspection on every shipment — including hardness verification (HB 110–130), seal compression force (18–22 N), and flow-rate validation (≥32 L/min at 2,200 rpm). Every unit undergoes full-load bench testing before dispatch, simulating real-world thermal cycling and pressure spikes. All water pumps carry a 6-month warranty against manufacturing defects — extended to 12 months for registered fleet accounts. With 10 years of export experience serving 120+ countries, our 20-person technical team verifies part compatibility using Kubota’s official service manuals — not guesswork. Our Guangzhou warehouse holds 1,200+ units of this SKU in stock year-round, enabling same-day pick and pack for urgent orders.

Every day your equipment remains offline cuts into profitability: act now to restore uptime and avoid cascading repair costs.
Q: Is this an original Kubota part or an aftermarket replacement?
A: This is an OEM-equivalent aftermarket water pump, manufactured by ISO 9001-certified factories to match Kubota’s dimensional, material, and performance specifications — not a recycled or refurbished unit.
Q: How do I confirm this fits my specific Kubota machine?
A: Provide your exact machine model (e.g., “M6040DTC-1” or “SVL75C”) and engine serial prefix (if available); our technical team will verify compatibility using Kubota’s official parts catalog and respond within 2 hours.
Q: What is the warranty period for this water pump?
A: We offer a 3–12 month warranty covering manufacturing defects. Warranty duration depends on application type and registration status — standard coverage is 6 months for all orders.
Q: What is the minimum order quantity?
A: MOQ is 1 piece. No minimum order value applies — ideal for urgent field repairs or diagnostic testing.
Q: How fast can I receive this part after ordering?
A: In-stock units ship within 2–5 working days. Express courier delivery takes 3–6 days to most destinations in North America, Europe, and Asia.
Q: Can I request a sample before placing a bulk order?
A: Yes — first-time customers may request one sample unit for functional evaluation. Sample fee is fully credited toward your first bulk order.
