Caterpillar PS-300B
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar PS-300B is a self-propelled pneumatic-tired (wobble-wheel) compactor built for finish rolling on asphalt paving jobs, sized in the middle of Cat's PS-series alongside the lighter PS-150B and PS-200B. It runs the Cat 3054T DIT, a turbocharged direct-injection four-cylinder diesel rated around 74 kW (99 hp) at 2200 rpm, driving a stepped powershift transmission through a torque converter, differential, and final-drive chains to the rear wheel bank, for a top travel speed of roughly 18 km/h (11 mph). Operating weight is adjustable by ballast: about 14.0-14.7 t (30,900-32,400 lb) unballasted, rising to roughly 21-21.3 t (46,200-46,960 lb) fully ballasted on standard units, with one configuration reported as high as 23.1 t (50,820 lb) — figures vary by ballast material and configuration. The machine used a 3-front/4-rear wobble-wheel layout with adjustable tire pressure and a front-and-rear tire sprinkler system, and it was built through roughly the late 1990s into the mid-2000s before Caterpillar replaced it with the PS-300C.
Cat's earlier plain-badged PS-300/PF-300 pneumatic compactor reportedly ran a third-party Deutz air-cooled diesel rather than a Cat engine; the 'B' generation moved the compactor onto Cat's own 3054T powertrain, a switch that mirrors what happened across several other Cat paving models of that era. The follow-on PS-300C then moved to the Cat 3054C engine meeting Stage II emissions limits and added a softshift powershift with a standardized 500-hour oil-change interval. In today's used and parts market, PS-300B units still turn up in asphalt-paving fleets doing tire-rolling duty behind the paver; buyers weigh wobble-wheel bearing play, ballast-tank integrity, and powershift fluid condition more heavily than raw hour count, and engine and driveline parts commonality across the mechanically injected PS-150B/PS-200B/PS-300B family keeps routine service parts reasonably available even as the model ages out of front-line fleets.

Servicing the PS-300B beyond the schedule
Predictive Maintenance & Fluid Analysis
Run oil-analysis sampling on the 3054T DIT engine, powershift/differential fluid, and hydraulic oil to catch turbocharger wear, injector fouling, and clutch-pack degradation ahead of failure. Track ballast-tank water level shift to shift; a slow leak quietly reduces compactive weight with no visible sign. Watch wobble-wheel bearing play at every station and confirm the tire-pressure system holds an even split across all stations, since uneven pressure mimics a bearing problem and skews compaction results.
Corrective & Common Repairs
Expect wobble-wheel bearing and spindle wear at individual stations before the tires themselves wear out, plus tire pickup traced to a blocked sprinkler nozzle or cracked spray line rather than tire compound. Sluggish powershift engagement usually resolves with a transmission fluid and filter service, not a clutch rebuild. No-start complaints on this mechanically injected 3054T typically trace to a fuel shutoff solenoid or a seat/neutral safety interlock, not the starter, battery, or wiring.
Overhaul & Rebuild Points
Major rebuild candidates on the PS-300B are the 3054T DIT engine (liners, bearings, injection pump) and the powershift transmission and torque converter, both driven by oil-analysis trends rather than a fixed hour mark. Wobble-wheel bearing and spindle assemblies across all stations tend to wear as a set on high-hour machines. Ballast tank or ballast box structure deserves inspection for through-rust or cracking, since these units now run two decades old and a compromised ballast system is a hidden rebuild driver.
Seasonal & Environment Servicing
Cold starts on the mechanically injected 3054T need correct-viscosity engine, transmission, and differential oil for the ambient range, plus a drained or protected ballast tank and sprinkler lines to prevent freeze cracking. In hot asphalt work, watch tire pressure and cooling-system airflow closely, since heat softens the wobble-wheel tires and stresses the turbocharger under sustained load. Flush sprinkler nozzles and scraper bars daily in warm-mix conditions to stop asphalt buildup that throws off compaction consistency.

PS-300B fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Coolant Temperature warning lamp (thermometer-in-liquid symbol) | Engine coolant temperature above normal operating range | Low coolant level, blocked radiator core, slipping or broken fan belt, faulty thermostat | Reduce ground speed, let engine idle to cool, then check coolant level and radiator fins once safe to open |
| Engine Oil Pressure warning lamp (oil can symbol) | Engine oil pressure below normal operating range | Low oil level, worn oil pump, plugged oil filter, oil galley leak | Stop engine immediately, check oil level and filter condition before restarting |
| Charging System warning lamp (battery symbol) | Alternator not charging or charging circuit fault | Loose or broken alternator belt, faulty alternator, corroded or loose battery/wiring connections | Check belt tension and battery terminal connections, test alternator output |
| Air Filter Service indicator (red/yellow band on air cleaner restriction gauge) | Air intake restriction has reached the service limit | Clogged primary or secondary air filter element, dust ingestion | Inspect and clean or replace the air filter element, reset the restriction indicator |
| Hydraulic Oil Temperature warning lamp | Hydraulic system oil temperature above normal operating range | Low hydraulic fluid level, clogged oil cooler fins, sustained high-load operation in hot ambient conditions | Idle down and let temperature drop, then check hydraulic fluid level and clean the cooler core |
| Fuel Level warning lamp | Fuel tank level has reached the low-fuel threshold | Tank nearing empty during a shift | Refuel before continuing operation to avoid air entering the fuel system |
| Air Intake Heater / cold-start indicator lamp | Cold-start aid (intake air preheat) is active before cranking | Normal cold-ambient start sequence, not a fault condition | Wait for the lamp to go out before engaging the starter |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
PS-300B attachments & work tools
Wheel and tire arrangement
Standard layout is 3 front and 4 rear pneumatic tires (offset rows for full-width overlap), size 13/80 x 20. Some spec listings round this to 8 tires; treat the exact count as 7 with overlap unless a dealer sheet says otherwise. This class uses free-oscillating wheel mounting rather than a bucket-style coupler.
Ballast system (steel/water)
Wheel loading is adjusted with removable steel ballast and/or water ballast rather than a swappable work tool. Reported maximum weight per wheel runs about 3,000 kg (6,600-7,260 lb depending on source), pushing operating weight from a standard low-teens-tonne figure up toward the low-20-tonne range; treat exact block counts and per-block weights as unconfirmed for this model and verify against the current dealer sheet.
Tire watering/spray system
An integrated water tank (roughly 450-460 L / 118-121 gal across sources) feeds spray bars or nozzles positioned over the tires to stop asphalt or soil pickup during rolling. This is a factory-fitted system, not an add-on kit, and has no separate hydraulic hookup requirement beyond the machine's own water pump.
Tire scraper system
Each tire carries a replaceable scraper blade that rides against the tread to strip stuck material; scrapers can be swung clear of the tire when not needed. This is standard equipment for the class rather than an optional work tool.
ROPS/canopy configuration
A two-post ROPS structure bolts to frame-mounted flanges as the standard operator protection, with a sun/weather canopy offered as the factory option in this size class. No cab enclosure option is documented for this model.
No quick-coupler work-tool system
As a pneumatic tire compactor, the PS-300B does not use a bucket/fork-style quick coupler. Its configurable items are limited to ballast loading, water spray, tire scrapers, and canopy/ROPS choice rather than interchangeable ground-engaging attachments.

PS-300B serial number reference
The PIN plate on a PS-300B is riveted to the main frame, typically on the front chassis near the articulation joint or on the right-hand side rail below the operator platform; a duplicate is often stamped on the ROPS mount or engine-side panel. Read the first three characters as the prefix, which identifies the model/build series, followed by the sequential unit number - do not confuse it with the separate engine serial plate mounted on the 3054T block.
| Prefix | Identifies | Notes |
|---|---|---|
| 4PN | PS-300B self-propelled pneumatic-tired compactor | Cat 3054T turbocharged 4-cylinder diesel, gross power about 74 kW (99 hp); a separate factory characteristics sheet lists 85 kW for the same engine, likely a different rating standard or altitude derate point, not a different engine. Operating weight ranges 14.7-21.7 t (32,400-47,800 lb) depending on ballast/configuration across model years (2000-2004 production window seen in dealer records). Distinct from the sibling PF-300B, which carries its own prefix on the same chassis/engine family. Only one dedicated source ties this prefix to the model by name - confirm against the PIN plate before ordering parts. |
Frequently asked questions
What engine does the Caterpillar PS-300B use?
A Cat 3054T DIT, a turbocharged direct-injection four-cylinder diesel rated around 74 kW (99 hp) at 2200 rpm. It sits above the naturally aspirated PS-150B and the turbocharged (non-DIT) PS-200B in the same family; the earlier plain-badged PS-300/PF-300 predecessor reportedly used a Deutz engine instead.
What is the operating weight of the Caterpillar PS-300B?
Around 14.0-14.7 t (30,900-32,400 lb) unballasted, rising to roughly 21-21.3 t (46,200-46,960 lb) fully ballasted on standard units; one configuration is reported as high as 23.1 t (50,820 lb). Weight varies by ballast material and configuration, so weigh an older machine rather than trust the spec plate.
What replaced the Caterpillar PS-300B?
The Cat PS-300C succeeded it, carrying a Cat 3054C turbocharged diesel meeting Stage II emissions limits, a softshift powershift transmission, and a standardized 500-hour oil-change interval.
What PS-300B owners discuss
What engine is actually in the PS-300B, and how does it relate to the rest of the PS-series?
The PS-300B runs a Cat 3054T DIT, a turbocharged direct-injection four-cylinder diesel rated around 74 kW (99 hp) at 2200 rpm, with roughly 4.0 L displacement. It sits above the lighter PS-150B (naturally aspirated 3054) and PS-200B (turbocharged 3054T without the DIT charge-air treatment) in the same family. Because the block and injection layout are shared across the line, symptoms like hard starting, smoky exhaust, and power loss look alike whether the machine is a 150B, 200B, or 300B, but boost pressure, fueling, and parts are not interchangeable between the variants. Confirm the exact engine arrangement against the machine's own plate before assuming a fix that worked on a sibling model applies here.
What wear pattern shows up on the wobble-wheel tires, and what does it usually mean?
Front and rear wobble-wheel banks are offset so every pass overlaps, giving full-width coverage. When one tire station scuffs or picks up mix while its neighbors look fine, operators report it usually traces back to a worn wobble bearing or spindle on that station rather than the tire compound itself. Before condemning a bearing, check tire pressure at every station first — an unequal pressure split across the roller can mimic the same uneven-wear symptom. On a higher-hour machine, expect at least one or two wobble stations to need bearing attention before the tires themselves are due.
How does the variable ballast and tire-pressure system affect compaction results, and what fails on older units?
Operating weight is adjustable from the machine's base shipping weight up toward a maximum ballasted weight (sources put the range roughly between 14.7 t and 21 t, varies by ballast material and configuration), and tire pressure across the roller is adjustable in roughly the 400-800 kPa (60-120 psi) band typical of asphalt pneumatic rollers, to fine-tune compactive effort per lift. On these early-2000s-era units, water ballast tanks that have sat exposed for two decades are the usual failure point — a slow leak drops effective weight without any obvious outward sign. Weigh the machine rather than trust the spec plate on an older, well-used unit.
What's the common complaint with the tire sprinkler/anti-pickup system?
The PS-300B sprays water on the front and rear tire banks to keep hot asphalt from sticking to the rubber during rolling. The most repeated complaint is a plugged nozzle or a cracked spray line rather than a pump or tank fault. Screening the water supply and flushing the lines each shift prevents most of it. A single tire picking up mix mid-pass while the rest of the roller stays clean is almost always a blocked jet on that station, not a tire compound problem.
How does the powershift transmission behave when it starts acting up?
The PS-300B uses a stepped powershift transmission with multiple forward and reverse speed ranges rather than a hydrostatic drive, topping out around 18 km/h (11 mph) of travel speed. A shift that's slow to engage or that slips under load is reported to trace back to transmission fluid condition and level, or a worn modulation valve, well before it points to worn clutch packs — a fluid and filter service resolves a lot of 'sluggish shift' complaints on higher-hour machines before any teardown is needed. Because it's a stepped powershift, any creep or drift while the machine is parked in neutral is not normal behavior and should be investigated, not treated as expected wear. Have your dealer verify transmission and parking-brake function on any machine that creeps in neutral before it goes back into service.
What electrical or no-start issues come up on this generation of machine?
This generation of PS-300B (built in the early 2000s window, sources vary on exact start/end years) carries mechanically injected fueling with minimal electronic engine control compared to later Tier-emissions pavers, so most reported 'electrical' complaints trace back to basic wiring — corroded grounds, a worn start switch, or a bad gauge sender — rather than any control-module fault. A no-start with normal cranking is more often a fuel shutoff solenoid or a seat/neutral safety interlock than a wiring problem, so check the interlocks before chasing the starter or battery. Have your dealer verify the fuel shutoff solenoid and safety interlock wiring before replacing starting components on a no-start complaint.
What should I check before buying a used PS-300B?
Listings for this model span a wide hour range at similar asking prices, so hours alone don't tell the condition story. Walk every wobble-wheel station and check for bearing play or wobble, not just tire tread depth. Check the ballast tank or ballast box for leaks or through-rust, since a compromised ballast system quietly reduces compactive weight. Cycle the tire-pressure system and confirm it holds an even pressure across all stations, and run the sprinkler jets front and rear to confirm none are blocked or missing. Pull an oil and coolant sample on the 3054T DIT — turbocharged engines in this family show glazed cylinders and oil contamination sooner than the naturally aspirated PS-150B if air filter or oil service was neglected. Have your dealer verify engine hour-meter history and inspect powershift transmission fluid condition before finalizing a purchase, since a transmission or turbo rebuild can quickly exceed what an older unit is worth.
