Caterpillar PF-300
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar PF-300 is a self-propelled, rubber-tired paving compactor (pneumatic-tire roller) built for finish-rolling asphalt mats behind a paver, not an asphalt paver itself and not an attachment-carrying machine. It rolls on pneumatic tires staggered three in front and four in back, riding on an independent hydraulic-cylinder oscillating suspension that lets each wheel find grade and hold even ground contact pressure, backed by a water spray system that wets the tires to limit hot-mix pickup. Three distinct generations share the PF-300 name but differ by engine and serial prefix: the base PF-300 (prefix 7WD) runs a Deutz F6L912 air-cooled inline-six diesel rated near 103 hp with no electronic engine management; the PF-300B (prefix 6HM) moved to a Caterpillar 3054T/3054 DIT turbocharged diesel rated roughly 99 to 105 hp; and the PF-300C (prefix PFB) uses a Caterpillar 3054C turbocharged diesel rated 75 kW (100 hp) meeting Stage II emissions. Operating weight spans roughly 14,000 to 16,100 kg (30,900 to 35,500 lb) unballasted up to about 21,000 to 23,100 kg (46,200 to 50,800 lb) fully ballasted, depending on standard versus Added Weight configuration and the number of steel ballast blocks fitted. The machine is offered with a ROPS canopy as standard and an enclosed cab as an option, and it shares chassis architecture with the sibling PS-300 roller line, which links the rear wheels hydraulically in addition to the front.
What changed across the PF-300's run is mostly the powertrain and its emissions compliance rather than the compaction concept itself: the earliest machines used a mechanical, analog Deutz engine with no fault-code diagnostics, the B-series switched to a Caterpillar-branded turbocharged diesel with more consistent power delivery, and the C-series added the electronics and aftertreatment needed to meet Stage II standards. Through all three generations the core layout stayed constant: hydraulically linked oscillating wheels, a chain-case final drive at each rear hub, a powershift transmission with a mechanical differential, and dual-circuit caliper disc brakes. In the used and parts market today the PF-300 matters because it remains one of the more common Cat pneumatic rollers still working asphalt finish jobs, and buyers and parts counters need the serial prefix to identify which engine and driveline family a given unit belongs to, since parts for the Deutz-powered base PF-300 do not interchange with the Caterpillar-engine B and C series.

PF-300 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) - Cat 3054T (PF-300B/PS-300B) or Cat 3054C (PF-300C/PS-300C) turbocharged direct-injection 4-cylinder diesel | 7 L (1.8 US gal) | Cat DEO (Diesel Engine Oil) 15W-40 for normal ambient range; Cat DEO-ULS or DEO SYN 5W-40 for cold-start conditions below 0 C (32 F), per Cat's standard multi-viscosity chart for this engine family |
| Cooling system | 28 L (7.2 US gal) | Cat ELC (Extended Life Coolant) or Cat DEAC (Diesel Engine Antifreeze/Coolant), factory pre-mixed 50/50 with water, freeze protection to about -37 C (-34 F) |
| Fuel tank | 215 L (50 US gal) | No. 2-D diesel fuel; ultra-low-sulfur diesel recommended for the turbocharged direct-injection engine |
| Transmission (3-speed, 3-range powershift) | 22 L (4.8 US gal) | Cat TDTO (Transmission and Drive Train Oil) SAE 10W or 30, TO-4 spec |
| Differential (mechanical traction unit) | 7 L (1.8 US gal) | Cat TDTO SAE 30, TO-4 spec - same fill class as transmission and final-drive compartments |
| Chain casings (wheel final drives, combined) | 9 L (2.4 US gal) | Cat TDTO SAE 30, TO-4 spec |
| Hydraulic tank | One dealer spec sheet lists 10 L (2.6 US gal), but this figure conflicts with the closely related PS-360B/PF-360B sibling (same 3054T engine and chassis family), which lists roughly 90 L (23.7 US gal) for the hydraulic tank. Treat the smaller figure as unverified - likely a transcription error in that source. Capacity varies by configuration; confirm against the machine's own OMM by serial number before servicing | Cat HYDO Advanced 10 (or equivalent Cat HYDO 10W) for normal climate; Cat HYDO Advanced 5 or Cat TDTO as a cold-weather alternative below about -20 C (-4 F) |
| Tire ballast / water spray system (non-lubricant fill, listed alongside refill capacities) | 460 L (118 US gal) | Water; a calcium chloride solution is an option for added ballast weight and freeze protection in cold climates |
| Grease points (chassis, steering linkage, roll pins) - spec only, no bulk reservoir | not applicable (point-lubrication only) | Cat Prime Application Grease or Cat Advanced 3Moly Grease, NLGI 2 multipurpose extreme-pressure grease |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the PF-300 beyond the schedule
Predictive Maintenance & Fluid Analysis
The PF-300 carries three oil systems that never share fluid: the engine crankcase (Deutz F6L912 on the base series, Cat 3054T/3054C on B and C series), the powershift transmission and torque-converter housing, and the chain-case final drives at each rear hub. Track wear metals in chain-case oil closely, since the chain-and-casing final drive is a wear point unique to this pneumatic-roller line. Sample hydraulic oil at the tank sight gauge to catch cross-contamination in the oscillating-suspension cylinders before it shows up as uneven wheel loading on the mat.
Corrective & Common Repairs
Most PF-300 repair calls trace to the compaction system rather than the engine: worn or asphalt-picked tires, plugged water-spray nozzles that let hot mix stick to the rubber, and leaking oscillating-suspension cylinders that let one wheel ride high and streak the surface. Check the hydraulically linked front-wheel cylinders for balanced cross-porting after any cylinder reseal. On PF-300B/C machines, turbocharger and injector faults on the 3054-series diesel are the common driveline complaints; base PF-300 Deutz units fail mechanically, with no fault codes to guide diagnosis.
Overhaul & Rebuild Points
Major rebuild attention centers on the chain-case final drives and the oscillating-suspension cylinders, both of which see continuous flex loading from the machine's staggered pneumatic-tire rolling pattern. Inspect chain casings for seal failure and chain stretch at overhaul; a compromised casing seal is the usual cause of chain wear beyond spec. Base PF-300 Deutz F6L912 rebuilds are constrained by parts availability, while PF-300B/C 3054-series rebuilds follow standard Cat inframe kits. Verify the differential and transmission housings for shared-case wear before returning ballast blocks to service.
Seasonal & Environment Servicing
Cold-weather starts on the air-cooled base-PF-300 Deutz engine depend on functioning glow plugs and clean cooling fins, since there is no liquid cooling system to buffer temperature swings; PF-300B/C liquid-cooled engines need coolant checked for freeze protection instead. Drain and winterize the tire water-spray tank and lines each season to prevent burst nozzles and pump housings. In hot asphalt-paving conditions, increase tire-wetting frequency to limit mix pickup and inspect tire heat-shield covers if fitted. Re-torque ballast-block mounting hardware after seasonal storage before returning the machine to compaction work.
PF-300 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Coolant Temperature Warning Lamp (gauge cluster) | Engine coolant temperature has risen above the normal operating band shown on the analog temperature gauge. | Low coolant level, blocked radiator core/fins, worn or slipping fan drive, or a stuck thermostat. | Stop and idle the engine, check coolant level and radiator fins for debris, verify fan belt/drive operation, and check thermostat function before resuming work. |
| Engine Oil Pressure Warning Lamp (gauge cluster) | Engine oil pressure has dropped below the safe minimum shown on the instrument panel. | Low oil level, worn oil pump, plugged oil filter, or incorrect/diluted oil viscosity. | Shut the engine down immediately, check oil level and filter condition, and inspect for pump wear before restarting. |
| Air Filter Restriction Indicator (pop-up/visual gauge) | Air intake restriction across the filter element has exceeded the allowable limit. | Clogged primary or secondary air filter element from dust generated during compaction work. | Service or replace the air filter element and reset the restriction indicator. |
| Charging System Warning Lamp (gauge cluster) | Alternator is not producing adequate charging output to the battery circuit. | Loose or broken drive belt, failed alternator, or a damaged wiring connection. | Check belt tension and condition, test alternator output at the battery terminals, and inspect wiring for corrosion or looseness. |
| Powershift Transmission Oil Temperature Warning (gauge cluster) | Transmission/torque converter oil temperature has exceeded the normal operating range. | Low transmission fluid level, plugged transmission oil cooler, or sustained overload during compaction passes. | Check fluid level, inspect the transmission oil cooler for blockage, and reduce load or duty cycle until temperature normalizes. |
| 100-03 / 100-04 (Cat CID-FMI convention: Engine Oil Pressure Sensor Circuit) | On any 3054-family engine fitted with an electronic sensor circuit, this CID-FMI pair flags a sensor signal voltage above (03) or below (04) normal — an electrical fault, not necessarily a true low-pressure condition. | Damaged sensor, chafed or corroded harness wiring, or a bad connector at the oil pressure sensor. | Inspect the sensor wiring and connector, test sensor resistance/signal per the engine service manual, and replace the sensor if it fails spec. |
| 110-03 / 110-04 (Cat CID-FMI convention: Engine Coolant Temperature Sensor Circuit) | Standard Cat CID-FMI pairing for a coolant temperature sensor circuit fault (open or shorted), separate from an actual overheat event. | Damaged coolant temperature sensor or wiring fault in its circuit. | Inspect sensor circuit continuity and connector condition, test the sensor against spec, and replace if faulty. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
PF-300 attachments & work tools
Machine type note
PF-300 is a self-propelled pneumatic-tire (rubber-tire) paving compactor, not an attachment carrier. It does not accept excavator/loader-style work tools or quick couplers; "attachments" for this class means factory-fitted kits and configuration options bolted to the roller itself.
Ballast / added-weight kit
Operating weight is adjusted with a steel-block added-weight (ballast) kit fitted at each wheel station. Unballasted weight runs roughly 14,700-16,100 kg (32,400-35,500 lb); with max ballast the machine reaches about 21,000-23,100 kg (46,300-50,800 lb), adding up to roughly 3,300 kg (7,260 lb) per wheel. Exact figures vary by series (base, B, C) and HW (heavier-ballast) configuration.
Wheel and tire arrangement
Seven pneumatic tires are used, three in the front row and four in the rear (or vice versa), in a staggered pattern so each pass overlaps the gaps left by the row ahead for full-width coverage. Standard tire size is 13/80R20 (also listed as 13.80-20). Each wheel rides on an independent oscillating hydraulic-cylinder suspension so it stays in ground contact over uneven surfaces.
PS vs PF wheel-pattern variant
The PS and PF designations are factory wheel-arrangement variants of the same chassis rather than bolt-on attachments: the PF pattern is set up to leave a smoother, more uniform finish. Choose the pattern at time of order; it is not a field-swappable kit.
Water spray system
A factory-fitted water spray system with a nozzle at each wheel keeps tires clean and prevents asphalt pickup during mat rolling. Tank capacity is quoted from about 350 to 460 liters (92 to 118 gal) depending on series/configuration, feeding a manifold that can be run continuous or intermittent from the operator's station.
Wheel scraper / tire-cleaning kit
Adjustable high-strength scrapers mount against each tire to strip picked-up material, often paired with water-retention mats or coco matting between wheel rows to keep tread damp and clean. This is a factory/dealer-fit kit rather than a swappable work tool.
Operator protection: canopy or cab
An open ROPS canopy is the base operator protection; an enclosed, climate-controlled cab is offered as a factory option for year-round comfort and dust/noise control. Both are structural add-ons selected at order or through a dealer retrofit, not field-interchangeable tools.
HW (heavy-weight) configuration
A higher-ballast-capacity version of the PF-300C line (marketed as PF300C HW) extends the maximum ballasted operating weight and pairs it with a larger water spray tank, for jobs needing more static compaction force from the same chassis footprint.

PF-300 serial number reference
On Cat PF-300 pneumatic compactors the PIN/serial plate is riveted to the machine frame, typically near the operator's platform or on the chassis rail close to the engine compartment; plate position has shifted across the base, B, and C updates, so check both spots. The plate reads as a 3-character prefix followed by a 5-digit sequence number (for example PFB00123); the prefix identifies the model/generation and the digits are the sequential build number, so match the prefix — not the full string — against the model/generation table.
| Prefix | Identifies | Notes |
|---|---|---|
| 7WD | PF-300 (base, pre-letter series) | Serial prefix confirmed on a machine-specific PF-300 parts catalog page, separate from the sibling PS-300 catalog page which carries its own 7TD prefix. Engine reported as a Deutz F6L912 air-cooled inline-6 diesel rated around 76.9 kW (103 hp); this figure is not corroborated by a second independent source, so confirm with dealer before treating as fact. No firm production-year window found; catalog placement (predating the circa-2000 B-series) points to an earlier generation. |
| 6HM | PF-300B | Serial prefix confirmed on a dedicated PF-300B parts catalog page (range roughly 6HM00001 up), independent of the sibling PS-300B catalog, which carries its own separate 4PN prefix — do not merge the two. Engine is the Cat 3054T turbocharged 4-cylinder diesel; gross power is cited as about 74 kW (99 hp) in dealer-published spec literature, though other sources put it closer to 78 kW (105 hp) — figures vary by rating method (gross vs net), treat as approximate. Production dates to roughly 2000-2002. |
| PFB | PF-300C | Serial prefix confirmed on a dedicated PF-300C parts catalog page (PFB00001-UP), distinct from the sibling PS-300C catalog page, which carries its own separate prefix — do not merge the two. Engine is the Cat 3054C turbocharged diesel, 75 kW (100 hp), consistent with Caterpillar's own product literature. Literature dates from 2003 onward; no confirmed discontinuation date found. |
Frequently asked questions
What engine powers the Caterpillar PF-300?
It depends on the series. The base PF-300 (serial prefix 7WD) uses a Deutz F6L912 air-cooled inline-six diesel rated around 103 hp with no electronic engine controls. The PF-300B (prefix 6HM) switched to a Caterpillar 3054T/3054 DIT turbocharged diesel rated roughly 99 to 105 hp. The PF-300C (prefix PFB) uses a Caterpillar 3054C turbocharged diesel rated 75 kW (100 hp) meeting Stage II emissions.
What is the operating weight of the Caterpillar PF-300?
Shipping (unballasted) weight runs roughly 14,000 to 16,100 kg (30,900 to 35,500 lb) depending on standard versus Added Weight configuration. With full steel ballast blocks installed, operating weight reaches about 21,000 to 23,100 kg (46,200 to 50,800 lb), varying by series and ballast option.
What replaced the Caterpillar PF-300?
The PF-300 line progressed internally rather than being dropped for an unrelated model: the base PF-300 gave way to the Caterpillar-engine PF-300B, which was in turn succeeded by the Stage II-compliant PF-300C. No documented successor beyond the PF-300C has been confirmed.
