Perkins 4016 Parts List: Genuine OEM Part Numbers for the 4016-61TRG Generator Engine

The Perkins 4016 is the largest engine in the Perkins range—a V16 with 61.1 liters of displacement and generator outputs from 1,400 kVA to 2,500 kVA. The 4016-61TRG, the most common generator-spec build, delivers approximately 1,870 kVA prime / 2,060 kVA standby at 1,500 rpm (50 Hz) and is used in the most demanding power applications: hyperscale data centers, airport infrastructure, hospital campuses, mining power stations, and large commercial cogeneration schemes. Like the rest of the 4000 Series, the 4016 is built at Perkins’ Stafford, UK facility and shares its 160 mm x 190 mm bore and stroke with the 4008 and 4012.

This Perkins 4016 parts list is a technical reference for the genuine OEM components most frequently ordered for the 4016-61TRG and related 4016-61TRS / 4016-TAG builds. Because the 4016 is a low-volume, high-value engine, parts procurement discipline matters: every component is serial-number-sensitive, and ordering errors are expensive. Always verify against the latest Perkins electronic parts catalog using your full engine serial number.

Perkins 4016 Engine Overview and Key Specifications

The 4016 is a four-stroke, turbocharged and aftercooled V16 diesel with a 60-degree bank angle, one-piece cast iron block, wet cylinder liners, and a forged steel crankshaft running in ten main bearings. The generator-spec engine is governed at 1,500 rpm (50 Hz) or 1,800 rpm (60 Hz). The 4016’s 61.1-liter displacement delivers exceptional torque reserve—at typical generator load factors it operates at low Brake Mean Effective Pressure, which is why its overhaul interval (22,000-28,000 hours) is the longest in the 4000 Series.

Perkins 4016 Parts List: Fuel System Components

Fuel consumption on a fully loaded 4016 approaches 410 L/h at 2,000 kVA, which means the fuel system handles enormous flow rates. Filtration quality is paramount—a single contaminated fuel delivery can destroy sixteen unit injectors in minutes.

4016 Fuel Filters and Fuel Delivery

• Primary Fuel Filter / Water Separator — Perkins P/N 26510318: Shared across the 4000 Series. Service interval: 500 hours or annually. Given the 4016’s flow, use the sight bowl inspection habitually—water is the #1 injector killer on large engines.
• Secondary Fuel Filter (4 micron) — Perkins P/N 26510319: Final protection for sixteen unit injectors. Genuine elements only; the 4-micron rating is non-negotiable.
• Fuel Filter Base Gasket — Perkins P/N 26510321: Replace at each element service.
• Fuel Lift Pump (gear type, high capacity) — Perkins P/N 26510123: The 4016 uses the largest gear pump in the range to feed the V16’s fuel demand. Wear symptoms: pressure drop at load, erratic governor response, hard starting.
• Fuel Injector (unit injector) — Perkins P/N 26545703: Sixteen required, supplied as calibrated matched sets. Genuine injector life in clean-fuel standby duty: 12,000-15,000 hours; replace in full sets to preserve cylinder balance.
• Injector Hold-Down Clamp — Perkins P/N 26545708: Check torque at every injector service; a loose clamp allows injector rotation and sealing surface damage.
• High-Pressure Fuel Line (per cylinder) — Perkins P/N 26545714: Replace on any sign of chafing or surface crack—a fuel line failure on a 2 MW genset is a fire and shutdown event.

Perkins 4016 Parts List: Lubrication System

The 4016 lubrication system holds approximately 180 liters (47.6 US gallons) of oil including filters—the largest sump in the Perkins range. The duplex filter head and large-capacity oil cooler are matched to the V16’s heat load.

4016 Oil Filters and Pump

• Oil Filter (element, duplex) — Perkins P/N 26510343: Two elements per service, shared across the 4000 Series. Service interval: 500 hours (prime) or annually (standby).
• Oil Pump — Perkins P/N 26510107: The largest gear pump in the range, sized for the V16’s gallery volume. Minimum oil pressure: 1.0 bar at low idle.
• Oil Cooler Core — Perkins P/N 26510154: Replace if oil temperature exceeds 105°C with normal coolant temperature.
• Oil Pressure Sensor — Perkins P/N 26510179: Feeds the ECM; false low-pressure alarms on a 2 MW standby set are costly—replace sensors proactively at 8,000 hours.

Oil specification: SAE 15W-40 API CI-4/CJ-4 above -10°C; 10W-30 or 5W-40 below. The 4016’s oil consumption target is 0.1-0.3% of fuel consumption. Because the oil charge is large, oil analysis trending gives excellent early warning of liner, ring, or bearing wear.

Perkins 4016 Parts List: Cooling System

At 2,000 kVA, the 4016 rejects roughly 700 kW of heat to the cooling system. The standard arrangement uses twin jacket water pumps in some builds plus a high-flow raw water pump for heat exchanger packages; radiator packages use a large split-core radiator with dual fans.

4016 Water Pumps, Thermostats and Coolant Parts

• Jacket Water Pump — Perkins P/N 26510115: Shared with the 4008/4012 in standard builds; some high-rating 4016 packages use twin pumps—check your build sheet.
• Raw Water Pump — Perkins P/N 26510118: The largest bronze pump in the range for heat exchanger sets.
• Thermostat (82°C, dual housing) — Perkins P/N 26510199: Two thermostats in a dual housing; replace as a pair.
• Coolant Hoses (upper/lower) — Perkins P/N 26510225 / 26510226: Heavy-duty silicone hoses; inspect annually.
• Radiator Cap (15 psi) — Perkins P/N 26510244: Shared across the 4000 Series.

Perkins 4016 Parts List: Turbocharger and Air System

The 4016 is twin-turbocharged with one high-flow turbo per bank, moving a combined air flow of approximately 12 m³/min at rated power. This is the highest air-handling system in the Perkins range and the single most expensive serviceable subsystem.

4016 Turbochargers and Air Intake

• Turbocharger (complete, each bank) — Perkins P/N 26510142: Two required, high-flow units with bank-specific housings. Replace in pairs; a single turbo failure creates bank-to-bank boost imbalance that stresses the crankshaft and main bearings.
• Turbo Rebuild Kit — Perkins P/N 26510143: Bearings, thrust washer, seals per turbo.
• Air Filter Element (primary) — Perkins P/N 26510330: Shared with the 4000 Series; on the 4016’s air flow, a dirty element causes measurable power loss and smoke—monitor the restriction indicator closely.
• Air Filter Element (safety) — Perkins P/N 26510331: Replace every third primary change.
• Charge-Air Hose Set — Perkins P/N 26510197: Large-diameter silicone hoses; inspect for delamination annually. Boost leaks on the 4016 cause significant derating and high exhaust temperature.

Genuine verification on a high-value engine like the 4016 is critical: all high-value components carry laser-etched part numbers and Perkins holographic packaging. Counterfeit filters and injectors are documented in several markets, and the consequence of a counterfeit oil filter on a 2 MW engine is catastrophic—engine failure within minutes. Always source through authorized Perkins distributors or verified B2B suppliers with OEM traceability—see Perkins Parts Supplier China for supplier audit guidance.

How to Order Perkins 4016 Parts for B2B Buyers

The 4016’s low production volume means parts are often manufactured in batches rather than held in continuous stock. B2B buyers should plan orders around these realities:

1. Long-lead items—crankshafts, camshafts, and turbochargers may have 4-8 week lead times; forecast overhauls 6 months ahead.
2. Serial number is mandatory—the 4016 has multiple serial-number breaks; a wrong internal component is a full return shipment.
3. Kit ordering—filters by the case, gasket kits by the set, full overhaul kits for planned rebuilds.
4. Documentation—OEM Certificate of Origin and full commercial documents for customs on high-value shipments.
5. Warranty alignment—confirm parts warranty coverage (typically 12 months) and whether installation must be by a Perkins-trained technician for warranty validity.
