Every hour your tractor sits idle costs revenue — especially during planting or harvest season. Counterfeit or poorly engineered rebuild kits cause erratic fuel delivery, hard starting, power loss, and repeated pump failures. OEM kits demand 3–4 weeks lead time and carry 40% price premiums. And sourcing all correct seals, plungers, and timing components across multiple suppliers wastes hours you can’t afford.
This Delphi Lucas CAV DPA overhaul kit is manufactured in ISO 9001-certified factories and undergoes full functional testing before shipment — matching original performance specs for pressure stability, timing accuracy, and flow consistency. With 10 years’ experience supplying fuel system components to repair centers across North America, Africa, and Southeast Asia, XUNPO ensures every kit supports uninterrupted field operation — whether rebuilding a DPA pump on a John Deere utility tractor or servicing a Massey Ferguson engine in a remote farm workshop.
This DPA diesel engine injection pump repair kit performs reliably under high-load, variable-speed conditions typical in agriculture: plowing, baling, loader work, and long-haul grain transport. It maintains precise fuel metering at low RPMs for smooth idling and delivers consistent high-pressure injection during peak torque demand. Correct sealing and calibration are critical — a single misaligned gasket or worn delivery valve can drop rail pressure by 15%, triggering limp mode or stalling. That’s why this kit is trusted by fleet operators managing 20+ tractors across mixed-brand farms and agri-contractors maintaining equipment for third-party clients.
All precision components — including delivery valves, plungers, tappets, and governor springs — are machined to ±0.005 mm tolerance, ensuring identical fit and function versus original equipment. Critical wear surfaces undergo nitride heat treatment (HRC 58–62), delivering 2.1× longer service life than standard carbon steel parts under continuous duty. Viton®-based O-rings and gaskets resist diesel fuel, biodiesel blends, and temperature swings from –20°C to +120°C without swelling or compression set. Each seal kit includes factory-specified torque values and installation sequence notes — no guesswork required for technicians rebuilding pumps onsite.
A $25 “budget” kit may save upfront, but often fails within 200 operating hours — triggering repeat labor, diagnostic time, and unplanned downtime. In commercial farming, that’s $1,800+ per day in lost productivity and contract penalties. Genuine Delphi Lucas CAV DPA kit specifications require exact spring rates, bore concentricity, and surface finish Ra ≤ 0.4 µm — deviations compromise injection timing and combustion efficiency. Our DPA injection pump kit meets ISO 4020 and SAE J1939-71 compliance standards, reducing total cost of ownership (TCO) by extending service intervals and eliminating secondary damage to injectors or ECU systems.
We only source from ISO 9001-certified factories, with incoming material inspection performed on 100% of batches. Every rebuild kit undergoes pre-shipment bench testing for delivery pressure, leakage rate, and governor response. We provide 6-month warranty coverage against manufacturing defects — full replacement or refund, no questions asked. With 10 years exporting to 120+ countries, our team has verified over 14,000 part applications — including complex cross-brand compatibility like Delphi DPA pumps installed in non-OEM tractor platforms. Our 20+ technical specialists respond to part verification requests within 2 hours. And because we hold 10,000+ SKUs in our Guangzhou warehouse, this kit ships in 2–5 working days — no waiting for production runs.
Your tractor won’t wait — and neither should your parts order. Send us your machine model, current pump part number (e.g., 7135-110), and required quantity. You’ll receive a competitive quote within 24 hours. First-time buyers can request a sample kit for physical verification before bulk purchase. Every day delayed means more fuel waste, more missed deadlines, and more stress — act now to keep your fleet moving.
