The engine oil pump is the heart of the lubrication system. The Shacman 611600070100 lubricating oil pump draws oil from the pan through a pick‑up tube and forces it through the oil filter, oil cooler, and then into the main oil gallery. From there, pressurised oil is distributed to the crankshaft journals, connecting rod bearings, camshaft bearings, valve train, and turbocharger. A failing pump leads to rapid oil starvation, bearing seizure, and complete engine destruction.
This pump uses a pair of precision‑ground external gears (drive gear and idler gear) that rotate inside a cast iron housing. The tight clearances between gear teeth and the housing create a sealed chamber that moves a fixed volume of oil with each revolution. The integral pressure relief valve prevents excessive pressure at high rpm by bypassing oil back to the inlet side. The genuine Shacman pump is calibrated to maintain stable oil pressure even under extreme loads and high engine speeds.
In the WP12/WP13 engine, the oil pump is mounted directly to the front of the cylinder block and driven by the crankshaft gear. This direct drive ensures immediate oil pressure upon engine start – critical for protecting turbocharger bearings at idle.
The 611600070100 oil pump housing is cast from GG25 gray iron, which provides excellent damping properties, thermal stability, and wear resistance. The gear teeth are cut from case‑hardened alloy steel (SAE 8620 equivalent) and heat‑treated to achieve a surface hardness of 55–60 HRC with a tough core. This combination withstands the high shear forces of cold oil starts and millions of operating cycles.
After machining, all mating surfaces – housing, gear faces, and cover – are ground to a flatness of 0.02 mm to minimize internal leakage. The pressure relief valve piston is precision‑ground and lapped to ensure smooth movement and consistent opening pressure. The valve spring is shot‑peened for fatigue life and coated to resist corrosion. Aftermarket pumps often use lower‑grade materials and looser tolerances, leading to reduced oil pressure and premature wear.
Shacman’s oil pumps are assembled in a clean environment using automated gear alignment fixtures. Each pump is 100% flow‑tested on a dedicated test stand: it is driven at 2,000 rpm using calibration oil at 80°C, and the outlet pressure and flow rate are measured. The pump must deliver between 170 and 190 L/min at 5 bar. The pressure relief valve opening pressure is verified by gradually increasing pump speed; it must open between 6.5 and 7.5 bar.
Every pump is also leak‑tested: the inlet is sealed and the pump is pressurised to 3 bar with air; any leakage exceeding 5 cm³/min is rejected. Random samples are subjected to endurance testing: 500 hours of continuous operation at 3,000 rpm with oil temperature cycling from 80°C to 120°C. After the test, the pump must show no visible wear and must still meet flow specifications.
Gear backlash is measured using a dial indicator; acceptable range is 0.05–0.10 mm. Housing bore runout is held to 0.02 mm. Only pumps that pass all tests receive the Shacman OEM approval and the part number 611600070100. The pump is then cleaned, oiled, and sealed in a plastic bag to prevent corrosion.
Shacman installs sample oil pumps in X5000 test engines and runs them for 3,000 hours at full load, followed by teardown inspection. The pumps show no measurable gear wear, and oil pressure remains within 5% of original specification. This validation confirms a service life exceeding 1.5 million kilometers.
Replacing the 611600070100 oil pump requires engine disassembly (oil pan removal, front cover removal). After draining the oil, remove the oil pan, then unbolt the pump from the cylinder block (four M8 bolts). Clean the mounting surface and the drive gear interface. Install the new pump with a new gasket or O‑ring (supplied separately). Torque the mounting bolts to 20 Nm + 90° in a cross pattern.
Do not reuse the old bolts – they are torque‑to‑yield and must be replaced. Prime the pump by filling the inlet port with clean engine oil before installation to prevent dry start. After reassembly, start the engine and check oil pressure at idle (should be >1.5 bar) and at 2,000 rpm (should be 4–6 bar). This pump is compatible with all Shacman X5000 models equipped with WP12/WP13 engines. Always verify the OEM number 611600070100 before ordering.
During engine overhauls, inspect the oil pump for gear wear, housing scoring, or relief valve sticking. If the pump shows any signs of wear or if the engine has experienced a bearing failure (metal debris), replace the pump with a genuine 611600070100 unit. Also replace the pump whenever the oil pan is removed for major bearing service – the pump’s internal clearances are critical to oil pressure.
If oil pressure warning lights come on or the gauge shows low pressure (below 1.5 bar at idle after warm‑up), suspect a failing pump. Do not continue running the engine – oil starvation can destroy bearings in minutes. Replace the pump immediately. When replacing, also clean the oil pick‑up tube and replace the O‑ring. Keep a spare oil pump in your parts inventory for emergency engine rebuilds.
A properly functioning oil pump ensures that all bearing surfaces receive an adequate oil film, preventing metal‑to‑metal contact. Insufficient oil pressure leads to rapid bearing wear, crankshaft scoring, and eventual seizure. The genuine Shacman pump maintains stable pressure even under high‑load, low‑rpm conditions (e.g., pulling a heavy load up a grade).
In turbocharged engines, the oil pump also supplies oil to the turbocharger bearings immediately after start‑up. A weak pump can cause turbocharger bearing failure, resulting in oil leaks, smoke, and costly turbo replacement. The genuine pump’s high flow rate ensures the turbo receives adequate cooling and lubrication at all times.
Fleet data shows that engines rebuilt with genuine Shacman oil pumps experience 95% fewer oil‑pressure‑related failures and extend bearing life by over 500,000 km compared to engines using aftermarket pumps.
Aftermarket oil pumps often use cast iron of inconsistent quality, with poorly finished gear teeth and loose bearing clearances. The pressure relief valve may be incorrectly calibrated, causing either low oil pressure (bearing damage) or excessively high pressure (oil filter rupture). Genuine Shacman pumps are manufactured to exact OE specifications, with verified gear profiles, correct housing clearances, and calibrated relief valves.
Genuine pumps also include the correct drive gear interface; aftermarket pumps may have mismatched gear teeth, leading to noise and premature wear. The mounting holes are precisely located; aftermarket pumps often require filing to fit, risking misalignment and oil leaks.
Using OEM parts maintains your engine warranty and ensures that the lubrication system operates as designed. For fleets, this reduces unplanned engine failures and extends overhaul intervals. The genuine pump is an investment in engine longevity and operational reliability.
The cost of a genuine oil pump (typically $200–350) is modest compared to the cost of an engine failure due to oil starvation – a new engine can cost over $25,000. For a fleet of 50 X5000 trucks, using genuine 611600070100 oil pumps during overhauls reduces oil‑pressure‑related failures by over 90%.
Aftermarket pumps may fail within 200,000 km due to gear wear or relief valve sticking. Genuine Shacman pumps last the life of the engine (1.5 million km+), providing the lowest total cost of ownership. The improved oil pressure also reduces fuel consumption (lower friction losses) and extends bearing life.
Additionally, a reliable oil pump prevents unscheduled roadside breakdowns, keeping trucks on the road and earning revenue. The genuine pump is a small price for peace of mind.
