Caterpillar D342
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar D342 is a mechanical, naturally aspirated (later turbocharged as the D342T) inline-6 diesel engine of roughly 20.4 L displacement (146 mm bore x 203 mm stroke), produced from the mid-1950s into the 1970s. Output ranged roughly 191-300 hp depending on aspiration and series. Caterpillar offered it in industrial, marine, and vehicular arrangements, with the vehicular version powering the D8, D8H, D8K, and D9 crawler tractor and pipelayer lines as the direct successor to the earlier D13000-series engine. It ran mechanical injection and a mechanical governor throughout its life, with no electronic controls, and many vehicular installations used a small pony motor for cold starting rather than an electric starter alone.
Across its production run the main change was the shift from naturally aspirated to turbocharged output in the D342T, which raised power but introduced a cylinder-liner-seating issue that Caterpillar addressed with a factory spacer plate under the liner flange. Industrial and marine arrangements shared the base architecture but carried their own accessory packages, cooling setups, and mounting configurations, so specs and weight vary by series rather than following one universal figure. The lettered D342C generation succeeded the D342 as Caterpillar's next engine design. In today's used and parts market the D342 remains relevant mainly as a rebuildable powerplant for vintage D8/D8H/D8K/D9 crawler tractors and pipelayers still in service, where mechanical simplicity and rebuildability keep the engine viable long after factory support has ended.

Values vary by configuration, region, and serial range — confirm against your machine before planning transport or lifts.
D342 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with oil filter) | Not documented in the factory literature reviewed for this industrial engine package. Crankcase and full-flow filter capacity is not published as a single figure across surviving parts/operation literature for the D342 family; it varies by oil pan arrangement and filter housing fitted to a given unit. Confirm actual full-mark dipstick capacity against the O&M manual for your specific arrangement number and serial prefix before service. | Straight-run diesel engine oil graded by ambient temperature, per period Caterpillar lubrication practice for this mechanical (non-electronic) engine: a heavier single-grade oil for warm climates, a lighter grade for cold-weather starting. Do not carry over modern multi-grade Cat DEO 15W-40 / 10W-30 charts from current on-highway engine lines onto this unit without dealer confirmation; those apply to later engine families, not this one. |
| Cooling system | Not documented as a single figure. The D342 was fitted with different cooling arrangements depending on installation: radiator-and-fan package on vehicular/generator-set builds, remote radiator on some industrial packages, and raw-water heat-exchanger cooling on marine and some pump/oilfield packages. Capacity varies by which arrangement is fitted; verify against the O&M manual or cooling-system parts group for the specific unit. | Plain water with a corrosion inhibitor/antifreeze on closed radiator systems, per period Caterpillar guidance; raw-water-cooled industrial and marine packages circulate untreated water or coolant only in the closed jacket-water side, with raw water on the heat-exchanger side. Confirm the coolant type against the arrangement actually installed; do not assume a modern extended-life coolant spec applies without checking. |
| Fuel tank | Not applicable as a fixed factory figure. The D342 industrial engine is supplied as a bare power unit; fuel tank sizing is set by the machine or skid builder, not by Caterpillar for the engine itself. No tank capacity is published in the engine-level literature reviewed. | Diesel fuel per Caterpillar's standard diesel fuel specification of the era. No engine-level tank capacity to publish; check the host machine or generator-set builder's documentation for actual tank size. |
| Grease points (spec only) | Not applicable — grease points are serviced to fitting fullness, not a fixed volume; no chart-level capacity is published for this engine. | Caterpillar multipurpose chassis grease (or equivalent NLGI-graded multipurpose grease), applied at fan hub, water pump, and linkage grease fittings per the lubrication chart. Specific NLGI grade by climate is not confirmed in the sourcing reviewed. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the D342 beyond the schedule
Predictive maintenance & fluid analysis
No ECM means no fault-code diagnostics on the D342, so predictive work relies on scheduled oil sampling and visual inspection. Pull a sample at every oil change and watch for coolant intrusion, the classic warning sign of a failing oil cooler core, head gasket, or crankshaft seal on this engine family. Track fuel dilution and metal content in the sample to catch mechanical injector and jerk-pump wear early, before it shows up as rough running or smoke. Check coolant condition and pony-motor starting behavior at the same interval.
Corrective & common repairs
The most common D342 complaint is worn mechanical injectors and jerk pumps, causing hard starting, rough idle, and excess smoke; recalibration or replacement is the standard fix. Oil turning up in the coolant traces to one of four points, checked in order: oil cooler core, cylinder head gasket, crankshaft seal, or worn main bearings. Pony-motor starting failures usually come from the pony's own clutch, fuel, or ignition components rather than the main engine. Governor linkage wear causes surging and needs periodic adjustment or bushing replacement.
Overhaul & rebuild points
Turbocharged D342T units are prone to cylinder liner drop under boost; the factory spacer plate under the liner flange corrects the seating and should be checked at every major teardown, not only when a leak appears. Rebuild work centers on the injection pumps and nozzles, since mechanical wear there drives most performance loss over time. Inspect crankshaft journals and main/rod bearings for regrind needs, and reseat valves during the same teardown. Naturally aspirated blocks skip the spacer-plate check but share the same bearing and injector wear pattern.
Seasonal & environment servicing
Cold-weather starts depend on the pony motor and its own fuel and ignition system staying in tune, so service it before winter rather than after a failed start. Check coolant freeze protection and inspect the oil cooler core for scale, since this engine already carries an oil-in-coolant risk without added corrosion. In dusty industrial or quarry settings, service the air cleaner more often than the standard interval. Marine arrangements need raw-water cooling circuit and corrosion-protection checks specific to that installation, separate from the industrial service plan.

D342 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Low oil pressure gauge indication | Engine oil pressure reading below normal operating range on the mechanical gauge | Worn bearings, low oil level, oil pump wear, or plugged oil filter/screen | Stop engine, check oil level and filter condition, verify pressure with a shop gauge before restarting |
| High coolant temperature gauge indication | Coolant temperature reading above normal operating range on the mechanical gauge | Low coolant level, fan belt slip, radiator blockage, or water pump failure | Idle down, check coolant level and belt tension, inspect radiator and water pump once cooled |
| Low coolant level warning (where fitted) | Float-type or sight-glass indicator shows coolant below safe level | External leak, internal leak (head gasket/liner seal), or evaporation loss | Shut down, allow to cool, inspect for leaks before adding coolant and restarting |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.

D342 serial number reference
The serial tag on a D342 industrial or marine engine is a small metal plate riveted directly to the engine block (commonly near the fuel injection pump side or timing gear housing), not a modern equipment PIN plate. Read the first three characters as the prefix - two digits followed by one letter (e.g. 31B, 49B, 50B) - which identifies the engine block series/generation and application (industrial vs marine); the digits that follow the prefix are the sequential unit number for that specific engine.
| Prefix | Identifies | Notes |
|---|---|---|
| 31B | D342 industrial engine (base generation) | Earliest documented industrial range, roughly 31B1 through 31B3984; falls within the same official D342 engine service manual grouping that also covers 32B, 49B, and 50B. |
| 32B | D342 marine engine (base generation) | Marine range, roughly 32B1 through 32B2268; some parts references carry this prefix into D342C marine listings too, so don't use it alone to separate the two generations. |
| 50V | D342 engine (application not confirmed as industrial) | Documented only as a standalone D342 engine service-manual serial series; no industrial, marine, or vehicular designation is given in the source found. Single-source listing - confirm with dealer before ordering against this prefix. |
| 49B | D342C industrial engine (later generation, not base D342) | Approx range 49B1 through 49B1090. C-suffix successor generation - don't carry base D342 specs/fluids into this prefix without separate confirmation. |
| 50B | D342C marine engine (later generation, not base D342) | Approx range 50B1 through 50B1024. Same generation split as 49B - treat as D342C, not base D342. Some resale listings label 50B-prefixed engines as plain "D342" informally, but parts/service documentation ties this range to D342C. |
Frequently asked questions
What engine powers the Caterpillar D342?
The D342 is itself the engine, not a machine it powers: a mechanical inline-6 diesel of roughly 20.4 L displacement (146 mm bore x 203 mm stroke), offered naturally aspirated or turbocharged as the D342T, in industrial, marine, and vehicular arrangements including the D8, D8H, D8K, and D9 crawler tractor and pipelayer lines.
What is the operating weight of the Caterpillar D342?
Weight varies by arrangement and accessory package (industrial, marine, or vehicular) and is not published as one fixed figure across all configurations; treat installed weight as varying by series rather than a single confirmed spec for the standalone engine.
What replaced the Caterpillar D342?
Caterpillar's lettered D342C succeeded the D342 as the next engine generation. Specs, ratings, and parts differ across that generation split, so D342C figures should not be applied back to the base D342.
What D342 owners discuss
What's the biggest factory-known weak point on the turbocharged D342T versus the naturally aspirated D342?
Owners and vintage-Cat clubs consistently flag the D342T's tendency to drop cylinder liners once the turbo pushed output past the block's original design ceiling. Cat's factory fix was a spacer plate fitted between the block and cylinder head to control liner protrusion and support the liner flange; it eased the problem without fully eliminating it, since the turbo engine still ran close to the block's structural limit. If you're chasing a liner-drop symptom - sudden coolant loss, a new knock, or a liner that's worked loose at the counterbore - plan on a shop that can machine the block and fit liner inserts rather than a straight in-frame liner swap. Have your dealer or machine shop verify liner protrusion and counterbore condition before final assembly.
Owners report oil showing up in the coolant or foaming out the radiator cap on D342-powered machines - what's usually behind it?
This is a recurring complaint, most often on the turbocharged variant. The troubleshooting order owners use runs: oil cooler core leakage first (pressure-test it in isolation), then head gasket, then front crankshaft seal wear, and last main bearing clearance letting oil migrate into the water jacket. On dual-engine setups where a small gasoline starting motor shares coolant passages with the main diesel, a rough-running starting-motor cylinder has also been blamed for pushing byproducts into the shared coolant. Pressurizing the cooling system with shop air and watching for bubbling along the head gasket line is the standard bench check used to narrow things down before pulling the head. Have your dealer verify the actual leak path before committing to a head or liner job.
What's the real starting drill on a pony/starting-motor D342 setup, and why do people insist on the exact order of steps?
On D342 installations that use a small gasoline pony motor to crank the main diesel (common on D8-family tractors and a number of industrial setups from this era), the sequence gets discussed a lot because getting it wrong damages the pony motor or the ring gear. The consensus procedure: start and idle down the pony motor, open the main engine's compression release, engage the pony's clutch/brake lever to stop the drive pinion, mesh the pinion with the D342's flywheel ring gear, then rev the pony and pull the lever forward to crank the diesel. The compression release stays open until oil pressure builds, then it's closed so the engine can fire on all cylinders. Closing the release too early or skipping it is the most common way owners describe burning up a pony motor or chewing up the ring gear. Have your dealer or a mechanic experienced with pony-start Cats walk you through it the first time.
Do owners report much trouble with the fuel injection pump and injectors on the D342?
Yes - it runs a mechanical jerk-pump system with an individual pump and injection valve per cylinder, and it's one of the more common gripe points. Rough idle, uneven cylinder contribution, and hard-start or no-start complaints trace back to clogged or worn injectors and pump plungers far more often than anything electrical, since there's nothing electrical on this engine to blame in the first place. Pop-testing and recalibrating the injectors, and checking the rack and governor linkage for stiffness, is the standard remedy reached for at overhaul rather than chasing anything downstream. Have your dealer verify injector pop pressure and pump timing rather than judging purely from idle quality.
What should someone check before buying a used D342 or a D342-powered machine?
Buyers focus on a short list: exhaust color after full warm-up (persistent blue or white smoke points to worn rings or a head/liner leak, not just normal cold-start haze), oil condition (foam, a milky or grey tinge, or water droplets on the dipstick mean coolant is getting into the crankcase), and listening for a deep knock from the lower or mid block, which usually means bearing or liner trouble rather than something cheap to fix. Confirm whether the engine is the naturally aspirated D342 or the turbocharged D342T, since the liner-drop history applies mainly to the turbo variant, and ask whether the block already has the factory spacer plate or liner inserts fitted. Given the engine's age, also expect longer lead times sourcing pump, injector, and liner parts, and budget for a machine shop capable of block work rather than a simple parts swap. Have your dealer or a qualified diesel shop run a compression check and an oil/coolant cross-contamination check before you buy.
Is the D342 considered a "simple" engine to own because it has no electronics?
That's the general owner consensus for this era of Cat power - no ECM, no sensors, no harness to chase down - but people are careful to note that simple doesn't mean low-maintenance. Everything runs on mechanical governor action, jerk-pump fuel delivery, and manual valve and injector adjustment, so valve lash, injector service, and governor lubrication (fed partly by engine oil and partly by oil thrown from the governor weights back into the pump housing) still need regular hands-on attention. Owners describe the tradeoff as fewer failure modes to diagnose but more routine mechanical upkeep than a modern electronically controlled engine needs.
What do people say about parts and rebuild kit availability for a nearly 70-year-old engine like this?
Community sentiment is that new dealer stock for the D342 is thin at this point, but the engine was common enough - across D8 dozers, marine and generator-set use, and industrial power units - that aftermarket overhaul kits, cylinder liners, and rebuild kits are still being produced today. Sourcing a complete cylinder head or block casting is described as the harder end of a rebuild compared to gaskets, rings, or injector components. Anyone planning a full rebuild should expect to work with specialty vintage-diesel parts suppliers and other long-time owners to track down good used castings when new stock isn't available.
