Deutz diesel engines power a vast range of heavy‑duty equipment – from construction machinery and agricultural tractors to industrial gensets and material handling vehicles. The Bosch common rail unit pump 04287047 (also referred to as an Electronic Unit Pump – EUP) is a high‑precision injection component, fully compatible with Bosch EUP architecture and designed specifically for Deutz engine families that use individual pump‑per‑cylinder systems.
This unit pump delivers injection pressures up to 2,000 bar, enabling efficient combustion, lower emissions, and reliable performance even under the most demanding off‑highway conditions. Rsolid Engine Parts supplies the 04287047 as a brand‑new, Bosch‑compatible unit – 100% calibration tested, and backed by a full 12‑month warranty at competitive pricing.
1. Structural Advantages of the Bosch 04287047 Unit Pump
The 04287047 is an electronic unit pump (EUP) – a self‑contained, high‑pressure pumping element for one cylinder. Its engineering focuses on durability and precise fuel control for Deutz industrial engines:
Individual Cylinder Fuel Delivery – Each cylinder has its own dedicated pump, mounted directly in the cylinder head and driven by the engine camshaft. This allows independent electronic control of injection timing, duration, and quantity for every cylinder, optimising combustion and reducing emissions – critical for engines that operate at variable loads.
High‑Pressure Plunger & Barrel – Precision‑ground plunger and barrel assembly delivers injection pressures up to 2,000 bar (29,000 psi) , ensuring exceptional fuel atomisation for complete combustion, reduced soot formation, and improved fuel economy.
High‑Speed Solenoid Valve – A fast‑acting solenoid (typically 24V for Deutz industrial engines) receives signals from the engine ECU to control the start and end of injection. Response time under 0.5 ms enables multiple injection events per cycle (pre‑injection, main injection, post‑injection), reducing combustion noise and NOx emissions.
Reinforced Roller Tappet – The pump features a hardened roller tappet that rides directly on the camshaft lobe. This reduces friction and wear, extending service life even in high‑hour applications (10,000+ hours).
Wear‑Resistant Coating – Internal components (plunger, barrel, tappet) are coated to resist scuffing and corrosion, particularly important when running on low‑sulphur diesel or biodiesel blends (B5/B7).
Compact, Sealed Housing – The unit pump is designed to fit into a compact bore in the cylinder head. High‑pressure fuel connections and electrical connectors are fully sealed against dirt, moisture, and vibration typical of construction and agricultural environments.
Direct Bosch / Deutz Compatibility – Identical mounting dimensions, plunger diameter, solenoid connector, and fuel ports as the original Bosch 04287047 and Deutz OEM units. Plug‑and‑play replacement with no modifications.
Cross‑Reference Information – The 04287047 is often supplied as a service replacement for other Bosch numbers such as 04286813, 04286829, or Deutz OEM part numbers like 04287047 – always verify your original pump number.
2. Compatible Deutz Engine & Equipment Models (≤5)
The 04287047 unit pump is specifically calibrated for Deutz 2012, 2013, and 2014 series common rail diesel engines (typically Tier 3 / Stage IIIA). Common engine types include:
Deutz TCD 2012 L4 2V / 4V – 4‑cylinder, 2.9L to 4.0L, used in compact loaders, telehandlers, forklifts, and generators.
Deutz TCD 2013 L6 2V / 4V – 6‑cylinder, 5.7L to 7.2L, used in larger wheel loaders, excavators, agricultural tractors, and industrial gensets.
Deutz TCD 2014 L6 2V / 4V – 6‑cylinder, 9.0L to 10.0L, used in heavy excavators, scrapers, and large gensets (some variants).
Deutz BF/TCD 1013, 1015 series (certain common rail variants) – also compatible with 04287047; verify fitment.
Typical equipment brands that use these Deutz engines include:
Atlas Weyhausen wheel loaders (AR 55, AR 65, AR 75 series) with TCD 2012/2013
Bomag rollers and compactors (BW 213, BW 226, BW 219) with TCD 2013
JCB backhoe loaders (3CX, 4CX) and telehandlers (531‑70, 535‑95) with TCD 2012
Claas agricultural machinery (Lexion combines, Jaguar forage harvesters) with TCD 2013/2014
Liebherr excavators and wheel loaders (A900, L506, L509) with Deutz TCD 2012/2013
Manitou, Merlo, Dieci telescopic handlers also widely use these Deutz engines.
✅ Important Fitment Note – Before ordering, always verify your engine model (e.g., TCD 2012 L4 2V) and the original Bosch or Deutz part number on your existing unit pump. The 04287047 is often a direct supersession or cross‑reference to numbers like 04286813, 04286829, and Deutz OEM 04287047.
3. Common Failures & Professional Installation/Replacement Advice
3.1 Typical Symptoms of a Failing 04287047 Unit Pump
Misfiring or rough idle – One or more cylinders not firing correctly, causing uneven running. A cylinder cut‑out test will identify the faulty pump.
Loss of engine power – The engine feels weak under load, especially when accelerating or pulling heavy equipment. Black or white smoke from the exhaust indicates incomplete combustion.
Engine knocking (nailing sound) – Over‑fueling or incorrect injection timing on a specific cylinder, often due to a worn solenoid or stuck plunger.
DTCs specific to a cylinder – ECU codes such as “Cylinder X contribution/balance” or “Injector circuit – pump solenoid” appear on diagnostic tools (Deutz EMR, Bosch ESI[tronic], etc.).
Hard starting / extended cranking – Multiple faulty unit pumps reduce overall fuel delivery, making starting difficult.
Fuel in the engine oil – Internal seal failure allows diesel to leak past the plunger into the cylinder head gallery and then to the oil sump. Rising oil level with a diesel smell is a red flag.
External fuel leakage – Visible diesel around the base of the pump or at the high‑pressure line connection.
3.2 Professional Installation & Replacement Recommendations
Use a diagnostic tool (Deutz EMR, Bosch ESI[tronic], or generic with Deutz data) to perform a cylinder contribution test and read fault codes. Identify exactly which unit pump(s) have failed. On high‑hour engines (8,000+), it is strongly recommended to replace all pumps as a set.
Replace all fuel filters – Install new primary (water separator) and secondary fuel filters. Deutz engines are sensitive to contamination, especially in off‑highway applications.
Flush the fuel system – Drain and clean the fuel tank, blow out supply and return lines with compressed air. Unit pump systems are less sensitive than common rail, but debris can still damage new pumps.
Inspect the camshaft and roller tappets – If a pump has failed catastrophically (scored plunger, broken tappet), the camshaft lobe may be damaged. Measure cam lift and inspect for pitting. Replace the camshaft if necessary.
Change engine oil and filter – If diesel has leaked into the oil (rising level, diesel smell), change the oil and filter BEFORE installing new pumps.
Lubricate the new pump – Apply clean engine oil to the plunger, roller tappet, and O‑rings. Insert carefully to avoid damaging the camshaft or the cylinder head bore.
Torque the hold‑down bolts – Typically 25–30 Nm for the retaining clamp or flange bolts. Over‑torquing can distort the pump body. Use a calibrated torque wrench.
Install new high‑pressure fuel lines or reuse with care – If the line is damaged, replace it. When reusing, ensure the flare nut seats perfectly. Torque the line nut to the pump outlet: usually 25–30 Nm (M14 flare).
Connect the solenoid electrical connector – Ensure clean, dry contacts. Apply dielectric grease. The solenoid resistance should be within spec (typically 0.8–1.5 Ohms for 24V systems).
Prime the low‑pressure circuit – Crank the engine with the stop solenoid deactivated (or with injector lines loosened) until fuel flows without air bubbles.
Clear adaptation values – Use Deutz EMR or a compatible tool to reset learned cylinder balancing values and perform a “pump learn” or “cylinder equalisation” routine.
Perform a leak test – Start the engine and idle. Inspect each pump base, fuel line connection, and solenoid O‑ring for fuel wetness. Use a mirror to see under pumps.
Run a cylinder balance test – After installation, verify that all cylinders contribute evenly. Live data should show correction values within ±5% for all cylinders.
💡 Pro Tip – Unit pumps are sensitive to low battery voltage (especially on 24V systems). Always use a fully charged battery or a booster pack when troubleshooting. Low voltage can cause erratic solenoid operation and false DTCs. For Deutz engines, always use the correct solenoid resistance – aftermarket solenoids may have different characteristics and can damage the ECU.
