Caterpillar G3406

Maintenance schedule, common problems & OEM parts breakdown

The Cat G3406 is a stationary, spark-ignited natural gas engine sold as a bare gas-compression block or as a packaged natural gas generator set, not a mobile machine, so it carries no undercarriage or ground-pressure rating. It is a 14.6 L inline-six built on the same core block architecture as the diesel 3406C, offered naturally aspirated (NA) or turbocharged-aftercooled (TA) with a separate-circuit aftercooler (SCAC) on TA builds, rated at 1500 rpm for 50 Hz markets or 1800 rpm for 60 Hz. Gas-compression output runs roughly 160-242 bkW (215-325 bhp) at 1800 rpm depending on configuration, while generator-set electrical output spans roughly 108.5 kW up to around 260 ekW depending on NA/TA build, voltage, and standby or prime duty class. A bare engine weighs around 1,361 kg (3,000 lb) dry; packaged as a complete generator set with radiator, alternator, and control panel it runs roughly 4,082-4,309 kg (9,000-9,500 lb) dry, depending on rating and enclosure. Field units trace back to bare-engine production in the early 1990s, and Cat still lists the G3406 in its current gas-compression and generator-set line today, making it one of the longest-running platforms in the gas engine catalog. It ships with a mechanical or Woodward electronic governor depending on vintage, EMCP-series digital control panels on generator-set builds, and enclosure options from open skid through weather canopy to sound-attenuated housing.

The core mechanical architecture has stayed consistent across the run; what changes is configuration and controls. NA builds tolerate lower-BTU or lean field gas better but give up peak output; TA builds with the separate-circuit aftercooler make more power but need tighter fuel-quality and detonation control. Emissions packaging splits the line further: a rich-burn 0.5% O2 setup with air/fuel-ratio control and a three-way catalyst meets US NSPS rules for regulated sites, while a 2% O2 configuration without aftertreatment still ships for export or non-regulated locations. Governor and ignition hardware moved from mechanical governors and simpler ignition setups on early units to Woodward electronic governors and a digital Electronic Ignition System with dedicated detonation sensors on later builds, and generator-set control panels moved from early EMCP II through EMCP 4.1 and 4.2. That long, steady production run - bare engine blocks from the early 1990s and packaged generator sets still being assembled two decades later - built a large installed base in gas-lift, gas-gathering, wellhead compression, and standby or prime power service. It also built a deep used-parts and reman-core market: major mechanical components share heritage with the diesel 3406C, while ignition, detonation-sensing, and air/fuel-control parts are gas-engine specific and worth sourcing through a gas-engine parts channel rather than a diesel 3406 counter.

G3406 fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase and lube oil system (with filter, includes auxiliary oil reservoir)75.7 L (20.0 US gal) full-system refill capacity. Standard oil-change interval 750 hours, extendable per Cat S·O·S oil-analysis results.Cat NGEO (Natural Gas Engine Oil), SAE 40, low-ash formulation (about 0.4-0.6% sulfated ash) built for spark-ignited gaseous-fuel engines. Do not use standard diesel engine oil (Cat DEO) - natural gas combustion needs the anti-oxidation and anti-nitration package NGEO carries. SAE 40 monograde is the standard grade for continuous-duty stationary service; check the Cat gas-engine lubricant guide for a cold-start alternate grade in low ambient temperatures.
Cooling system (jacket water plus separate-circuit aftercooler, on turbocharged-aftercooled builds)37.9 L (10.0 US gal) total. Jacket water circuit 30.3 L (8.0 US gal); SCAC (aftercooler) circuit 7.6 L (2.0 US gal), turbocharged-aftercooled configurations only. Naturally aspirated builds carry the jacket water volume only, with no SCAC circuit.Cat DEAC (conventional heavy-duty coolant/antifreeze) or Cat ELC (Extended Life Coolant, organic-acid technology) mixed 50/50 with water; Cat NGEC (Natural Gas Engine Coolant) is the gas-engine-formulated option and needs no supplemental coolant additive at initial fill. SCAC circuit runs around 54°C (130°F) coolant temperature at rated load.
Grease, external fittings (spec only, no fixed fill volume)Not a reservoir system - service each fitting individually per the lubrication schedule.Cat Multipurpose Grease (NLGI 2, no moly) for general external fittings; Cat Advanced 3Moly Grease (NLGI 2, 3% molybdenum disulfide) for medium-load/medium-speed points. Standard service range roughly -30 to 40°C (-22 to 104°F); pick the grade for your ambient extremes per the Cat grease selection guide.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Caterpillar G3406 maintenance schedule

Service intervalTasks
Every 10 h
  • Check crankcase oil level before each start and top off with Cat NGEO SAE 40 if low.
  • Check jacket-water coolant level, and SCAC circuit level on turbocharged-aftercooled units, at the sight glass or expansion tank.
  • Walk down the fuel gas train - regulator, mixer, manifold connections - and check for gas odor or a hiss indicating a leak.
  • Scan the control panel for active alarms (high water temperature, low water temperature, low oil pressure, ECM fault) and log any flags before clearing them.
  • Listen for detonation, uneven firing, or a hot-running cylinder and note anything unusual for the next service visit.
  • Drain any fuel gas scrubber or moisture trap per site practice.
Every 250 h
  • Change crankcase oil and filter with Cat NGEO SAE 40, or confirm the current S·O·S sample supports running to the site's extended interval.
  • Pull an oil sample for Cat S·O·S analysis and compare the wear-metal trend against the prior sample.
  • Inspect and adjust the gas mixer or carburetor air-fuel setting.
  • Check the air/fuel-ratio control valve and exhaust oxygen sensor on rich-burn NSPS-equipped units for sticking or drift.
  • Inspect drive belts, hoses, and clamps for cracking, glazing, or seepage.
  • Verify detonation-sensor wiring and connectors are tight and free of corrosion.
Every 500 h
  • Cut open the used oil filter element and inspect for metal or debris consistent with the S·O·S trend.
  • Inspect ignition transformers, secondary leads, and boots for cracking, carbon tracking, or arcing.
  • Check turbocharger shaft play and boost pressure on TA units, and inspect for oil weeping at the seals.
  • Pull a coolant sample and check the corrosion-inhibitor level in both the jacket-water and SCAC circuits.
  • Clean or replace the air intake filter element.
Every 1,000 h
  • Check valve lash and adjust to spec per the engine's inspection schedule.
  • Inspect and torque-check exhaust manifold and turbocharger mounting hardware on TA units.
  • Test detonation-sensor function and confirm the ignition timing map hasn't drifted from the base setting.
  • Inspect the fuel gas pressure regulator diaphragm and shutoff valve for leakage or slow response.
  • Check generator-end bearings, brushes if fitted, and cooling airflow on packaged units, and re-torque skid and vibration-isolator mounting hardware.
Every 2,000 h
  • Replace spark plugs and inspect ignition transformers - Cat's published gas-engine interval runs closer to 1,500 hours, so treat 2,000 as the outer limit, not the target.
  • Inspect and recondition or replace the gas mixer or carburetor assembly.
  • Borescope the cylinder head, valve seats, and combustion chamber, or plan a top-end teardown if oil-consumption or compression trends call for it.
  • Inspect the jacket-water and SCAC water pumps for seal leakage and bearing play.
  • Review accumulated S·O·S oil and coolant trends with your dealer to plan the next top-end or overhaul window.
Every 4,000 h
  • Change jacket-water and SCAC coolant per the coolant product's rated service life (commonly cited around every 4,000 hours), or sooner per coolant-analysis results.
  • Plan a top-end overhaul - cylinder heads, liners, rings, bearings - once compression, blow-by, or S·O·S wear trends call for it rather than at one fixed hour number.
  • Rebuild or replace the turbocharger core on TA units when boost, oil consumption, or shaft-play checks show it's due.
  • Have your dealer re-verify detonation-sensor calibration and the full ignition timing map at major overhaul.
  • Recondition the governor, mechanical or Woodward electronic, and check the generator-set control panel for age-related drift.

Servicing the G3406 beyond the schedule

Predictive Maintenance & Fluid Analysis

Run Cat S·O·S oil and coolant sampling on schedule, not just at oil changes - natural gas combustion glazes cylinder walls faster than diesel duty, and wear-metal trends catch ring, guide, and bearing wear before it shows up as oil consumption. Track fuel gas methane number alongside samples; gas rich in propane, butane, or ethane lowers methane number and pushes the engine toward detonation. Log detonation-sensor readings each visit - drift is a common root cause of nuisance shutdowns blamed on the engine instead of faulty wiring.

Corrective & Common Repairs

Rough running or a hot cylinder traces most often to a fouled spark plug, a weak ignition transformer, or a module fault, not a mechanical problem - check ignition components before pulling a head. On rich-burn units, a fouled or sluggish exhaust oxygen sensor lets the air/fuel-ratio controller drift off target and shows up as rough idle or a hot cylinder. A detonation shutdown is often a loose sensor connector or damaged lead - verify wiring with diagnostic software before condemning the sensor or retiming the engine.

Overhaul & Rebuild Points

Base a top-end teardown on compression, blow-by, and S·O·S wear-metal trends, not a fixed hour number: continuous gas-lift or gas-gathering duty wears cylinder liners, rings, and valve seats faster per calendar year than standby generator duty. Rebuild the turbocharger core on TA units when boost or oil consumption drifts, since it directly affects detonation margin. At major overhaul, re-verify detonation-sensor calibration and the ignition timing map, recondition the governor, and check the gas mixer/carburetor assembly; these control-side parts age even when the block itself still measures within spec.

Seasonal & Environment Servicing

There's no undercarriage or ground-pressure concern on a stationary package; seasonal prep centers on fuel and cooling. Confirm the jacket-water heater and its breaker work before cold weather, since a failed heater trips the low-coolant-temperature alarm and complicates starts. Check antifreeze concentration in both the jacket-water and SCAC circuits for the freeze point. Watch fuel gas composition through seasonal supply shifts: heavier hydrocarbons lower methane number and raise detonation risk. On canopied or enclosed packages, keep cooling-air inlets clear so summer heat doesn't push SCAC temperature into a derate.

G3406 fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
MID 014 - CID 0325Ignition Detonation: the Electronic Ignition System (EIS) module has detected engine knock above the acceptable threshold.Lean or rich air/fuel mixture, low fuel gas methane number, high intake manifold air temperature, or ignition timing set too advanced.Check fuel gas quality and pressure regulator, verify air/fuel ratio and manifold air temperature, then confirm base timing before restarting; module first retards timing and will shut the engine down if detonation continues.
MID 014 - CID 0318 / CID 0319Right or Left Detonation (knock) Sensor circuit fault - open, shorted, or erratic signal from one of the two knock-sensing circuits feeding the EIS module.Damaged or disconnected sensor harness, corroded connector, or a failed sensor/accelerometer element.Inspect the sensor wiring and connector for damage or corrosion, check sensor resistance against spec, and replace the sensor if it reads out of range.
MID 014 - CID 0401 to CID 0412Ignition Transformer Secondary circuit fault on the affected cylinder - open circuit, short to ground, or a noisy secondary signal.Worn or fouled spark plug, cracked ignition transformer boot, damaged high-tension lead, or incorrect plug gap on that cylinder.Pull and inspect the spark plug on the flagged cylinder, check the transformer secondary lead and boot, and swap the transformer to confirm before condemning it.
MID 014 - CID 0301 to CID 0316Ignition Transformer Primary circuit fault on the affected cylinder - open or shorted primary winding or driver circuit.Broken primary wiring, a loose or corroded connector, or a failed EIS module output driver for that cylinder.Check primary wiring continuity and connector condition, then test the transformer primary resistance; if wiring and transformer check good, suspect the EIS module driver.
MID 014 - CID 0591EEPROM checksum fault or EIS control module not programmed.Corrupted module memory, a replacement module that was never configured, or an electrical transient that scrambled stored parameters.Reprogram the EIS module with the correct engine configuration using Cat ET; replace the module if it will not hold a valid checksum after reprogramming.
AL1High Water Temperature Alarm on the genset control panel - coolant temperature is approaching the high-temperature shutdown setpoint.Low coolant level, restricted radiator or heat exchanger, weak fan or jacket water pump, or sustained overload.Check coolant level and cooling system condition, confirm fan and pump operation, and reduce load while monitoring the temperature trend.
AL2Low Water Temperature Alarm on the genset control panel - coolant temperature has dropped to the low-temperature alarm setpoint.Jacket water heater failure, its breaker left off, or low ambient temperature before start.Verify the jacket water heater, its thermostat, and its power circuit before the next start attempt.
AL3Low Engine Oil Pressure Alarm on the genset control panel - oil pressure has dropped into the band just above the shutdown setpoint.Low oil level, a clogged oil filter, a worn oil pump, or a drifting oil pressure sender.Check oil level and filter condition first, then verify the sender reading against a mechanical gauge; inspect the pump if level and filter are good.
AL4Engine ECM Fault alarm on the genset control panel - the EIS engine control module has an active alarm or shutdown fault of its own.Any underlying EIS-reported fault, such as an ignition, detonation-sensor, or EEPROM condition.Connect Cat ET to the EIS module to pull the specific active CID-FMI code, then service that circuit; AL4 alone only flags that an engine-module fault exists.

Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.

G3406 attachments & work tools

Machine type note

The G3406 is a stationary spark-ignited natural gas engine block used in gas compression and generator-set packages, not a work-tool-carrying machine. No coupler or work-tool attachment system applies; entries below cover factory package/configuration options instead.

Cooling package

Offered with an engine-driven, skid-mounted radiator for outdoor/mobile packages or a heat-exchanger/jacket-water circuit for indoor or remote-cooling installs. A jacket water heater is a common standard fitment to aid cold starting.

Enclosure / weather protection

Genset packages range from an open skid to a weather-protective canopy (sometimes called a Texas-style canopy) up to a full sound-attenuated enclosure for noise-sensitive sites. Mobile variants are also built as trailer-mounted units for temporary or rental power.

Control panel / governor

Depending on package vintage, units ship with an EMCP 2, EMCP 4.1, or EMCP 4.2 digital genset control panel. Speed and frequency are held by an electronic (Woodward-type) governor, commonly paired with an Altronic-type ignition module.

Fuel system / ignition / emissions

Rich-burn, spark-ignited natural gas combustion with a gas carburetor-type fuel system (0.5% O2 rich-burn calibration). Where NSPS emissions rules apply, the package adds Cat-supplied air-fuel-ratio control (AFRC) plus a customer-supplied three-way catalyst aftertreatment; non-regulated sites can run without the catalyst.

Aspiration / output rating

Built on the G3400 platform in naturally aspirated (NA) and turbocharged-aftercooled (TA) form. Mechanical-drive (gas compression) output spans roughly 160-272 bkW (215-365 bhp) at 1800 rpm; generator-set electrical output varies by configuration/series, with examples reported from roughly 139 ekW up to about 260 ekW standby depending on NA/TA build, voltage, and site rating.

Skid / mounting package

Standard factory skid package includes a muffler, water-cooled exhaust manifold, skid base, and manifold/turbo guarding; mobile genset skids commonly add a sub-base fuel tank. Packages are offered stationary skid-mounted or trailer-mounted for mobile deployment.

Electrical output configuration

Generator-set builds are configured for 50 or 60 Hz, single- or three-phase output, with common voltage bands in the 208-480V range. Units can be set up for standby or prime/continuous duty and paralleled through external switchgear on multi-unit sites.

G3406 serial number reference

The engine's own PIN/serial plate is affixed to the block, commonly near the front lift bracket, and carries a three-letter engine prefix — 1RK, 4FD, 5NW, or CTS on naturally aspirated (NA) blocks, CRE on turbocharged-aftercooled (TA) blocks. A packaged generator set carries a second nameplate on the skid or control panel with its own package serial prefix — KAR or R7E on TA-configuration skids — which will not match the engine's serial number on the same unit. Both formats read as a 3-letter prefix followed by a sequential number (example: 4FD00393) — the prefix identifies the engine build or package block, the digits are the individual unit sequence, not a date code by themselves.

PrefixIdentifies
1RKBare engine, Gas Engine (industrial application)
4FDBare engine, Industrial Engine Natural Gas / Gas Engine
5NWBare engine, Industrial Engine (natural gas)

Frequently asked questions

What engine does the Cat G3406 use?

The G3406 is the engine itself - a 14.6 L, spark-ignited, inline-six natural gas engine built on the same core block as Caterpillar's diesel 3406C, offered naturally aspirated (NA) or turbocharged-aftercooled (TA). It doesn't run on diesel fuel; it burns pipeline natural gas, field gas, biogas, or propane depending on package, ignited by spark plugs and a digital ignition module rather than compression.

What's the G3406's operating weight?

There isn't an 'operating weight' in the mobile-machine sense here - this is a stationary engine, not a machine with an undercarriage. A bare engine block weighs around 1,361 kg (3,000 lb) dry. Packaged as a complete generator set with radiator, alternator, and control panel on a skid, dry weight runs roughly 4,082-4,309 kg (9,000-9,500 lb), varying with kW rating and enclosure type. Check the specific package's nameplate for an exact figure.

What replaced the G3406?

Nothing formally superseded it - Cat still lists the G3406 in its current gas-compression and generator-set engine lineup, one of the longer-lived platforms in the catalog. Where more output is needed, Cat's own gas engine range steps up within the same G3400 platform family to the eight-cylinder G3408 and twelve-cylinder G3412, and further to the larger G3500/G3600 series for bigger continuous-duty blocks.

What G3406 owners discuss

What ignition-system quirks come up most with the G3406 gas engine?
The G3406 is spark-ignited, not compression-ignited: a mixer or carburetor blends air and natural gas ahead of the cylinders, and spark plugs plus ignition modules fire the charge. Expect spark plug and ignition module replacement as routine service roughly every 1500 hours, not as a sign of failure. Rough running, misfire, or one cylinder running hot usually traces to a fouled plug, a weak ignition module, or a mixer that has drifted out of adjustment, not a mechanical fault in the block.
How does the detonation (knock) protection system work, and what actually trips it?
Compression ratio on the G-series is set lower than the diesel 3406 specifically to hold detonation margin, and the engine control adds detonation sensors that can retard timing (detonation retard) or shut the unit down (detonation shutdown) when knock is sensed. In the field, a detonation trip gets blamed on fuel quality before the sensor: the fuel's methane number needs to stay within a tight band of the engine's design point (commonly cited as about plus or minus 3), and gas that's richer in propane, butane, or ethane lowers methane number and knocks more easily. Pull a fuel gas analysis before assuming the sensor or wiring is at fault. Have your dealer verify detonation-sensor calibration and timing maps after any repeated shutdown event.
What's normal for the cooling system, and what should raise a flag?
Most G3406 gas-engine packages run a separate-circuit aftercooler (SCAC): one pump and circuit cool jacket water, a second independent pump and circuit cool the aftercooler at a lower target temperature than jacket water. That split exists because gas engines need a cooler intake charge than diesels to hold detonation margin and support rated power. If the aftercooler circuit runs hot while jacket water looks normal, expect a power derate and reduced knock margin. Treat that as a real fault, not just a warm-weather nuisance alarm.
What sensor or control issues come up most often?
On rich-burn units with air/fuel ratio control (AFRC), the exhaust oxygen sensor and the AFR control valve are the first things to drift or foul. A sluggish or contaminated O2 sensor lets the controller run the mixture off target, which shows up as rough idle or elevated exhaust temperature on individual cylinders more often than a hard fault code. Detonation sensors and their wiring are the other frequent complaint: a loose connector or damaged lead can trigger a false detonation retard or shutdown that looks like an engine problem but is really a wiring fault. Have your dealer verify with diagnostic software before replacing sensors on a hunch, since a wiring fault and a real detonation event can look the same from the operator's seat.
Do these engines burn oil differently than a diesel of similar size?
Yes, oil consumption gets discussed more on natural gas engines than on an equivalent diesel. Lighter loading or extended idle lets combustion deposits glaze the cylinder walls, and that lets rings and valve guides pass more oil over time. The fix cited most often is running the engine closer to rated load, keeping to oil-sample intervals, and using an oil formulated for gas engines rather than a generic diesel oil. Oil consumption that climbs between samples is treated as an early wear signal worth a compression and blow-by check, not something to just top off.
What generation or configuration differences should I watch for on a G3406?
These shipped as both naturally aspirated (NA) and turbocharged-aftercooled (TA) versions, and at both 1500 and 1800 rpm ratings. Continuous gas-compression output runs roughly 160-242 bkW (215-325 bhp) at 1800 rpm on factory data sheets, while generator-set ratings sit lower, in the neighborhood of 108-155 kW at 60 Hz; used-unit listings show figures across and even outside that spread, so treat output as varying by configuration/series rather than one fixed number. Governor hardware also varies by vintage — expect to find both older mechanical governors and Woodward electronic governors in the used population. Match any spec sheet to the actual serial number and rating plate rather than assuming a generic G3406 datasheet applies.
What should I check before buying a used G3406 unit?
Get total hours and hours since the last top-end or overhaul, not just total hours. A high-hour unit with a documented recent overhaul is worth more than a lower-hour unit that has never been opened. Ask for oil and coolant sample history; stable wear-metal trends over time say more than one snapshot. Look for coolant or oil weeping around the block and cylinder heads, and confirm whether the unit ran continuous duty (gas compression, combined heat and power) or standby, since continuous duty accumulates wear faster per calendar year. Ask for a load test rather than a start-and-idle demo, and compare the hour meter reading against the physical wear you can see — a meter that looks too clean for the claimed hours is a red flag. Have your dealer verify compression, detonation-sensor function, and overall combustion health before final purchase.
