Caterpillar CP-573E

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar CP-573E is a single-drum vibratory padfoot soil compactor built for embankment, subgrade, and trench-backfill compaction, not asphalt paving. It runs a turbocharged, electronically controlled Cat 3056E diesel rated at roughly 112 kW (150 hp) gross. Bare operating weight with a ROPS/FOPS canopy and no blade runs about 13,750 kg (30,310 lb); add the leveling blade and it climbs to roughly 13,935 kg (30,720 lb), and a factory cab adds about another 325 kg (715 lb) - actual weight varies by configuration. Cat built the CP-573E alongside a smooth-drum sibling, the CS-573E, which could take a bolt-on padded shell kit to mimic the CP's padfoot action; both share the same engine, drum-cooling, axle, and vibratory-support hardware. Spec listings place its production run in the mid-2000s, sitting in Cat's mid-size E-series compactor family between the smaller 563E and the larger 583E, 663E, and 683E models.

Across the E-series lineup the CP-573E's core layout stayed constant: the same 3056E engine, eccentric-weight vibratory drum, and lubrication architecture used on the 563E through 683E siblings, with operating weight and drum width scaling up by model. Cat later retired the whole 563E-683E numbering scheme in favor of a production-class lineup with different engines and controls, so the CP-573E sits in a distinct, closed generation of parts and service knowledge. That keeps surviving CP-573E units a practical source of interchangeable driveline, hydraulic, and vibratory-system components across the whole E-series family, and sustains demand for the model on the used and parts markets even though it left production years ago.

Servicing the CP-573E beyond the schedule

Predictive Maintenance & Fluid Analysis

Pull scheduled fluid samples from the 3056E engine oil, rear axle, hydraulic tank, and both final-drive planetaries, plus the vibratory support housing and the eccentric weight housings on each side of the drum. Watch the drum final-drive drain plug for metal debris larger than 3 mm; that signals gear wear inside the planetary. Check vibratory frequency against the 1450-1850 VPM range on machines with the variable control - a drifting reading often flags eccentric-weight bearing wear before drum vibration noticeably weakens.

Corrective & Common Repairs

Common CP-573E fixes center on the propel and vibratory controls: a neutral start switch out of adjustment can let the engine crank with the propel lever out of STOP, and the vibratory amplitude switch must be cycled to OFF to reset the controller after a nuisance shutdown. Padfoot drum scrapers (steel, flexible, or padded) need frequent readjustment as pads wear. Expect fuel filter and water separator service after fuel-related faults, and check battery cables and circuit breakers when charging or ECM faults appear.

Overhaul & Rebuild Points

Major rebuild points are the eccentric weight housings, one on each side of the drum, which need a full drain, flush, and refill at 3000 hours or 3 years, plus the final-drive planetaries at the drum and rear axle. Inspect the crankshaft vibration damper at 2000 hours or 2 years for cracking, and replace the cooling system water temperature regulator at 3000 hours or 2 years after the system is drained and cleaned. Never weld on or straighten the ROPS/FOPS canopy; replace the mounting support if it has developed play.

Seasonal & Environment Servicing

Below 0°C (32°F), warm the 3056E at low idle for 15 minutes or longer before working the drum or propel system; below -18°C (0°F), allow extra warm-up time if hydraulic response feels sluggish. Tires carry a calcium-chloride and water ballast for weight and antifreeze protection, so check the ballast level with the valve stem at 12 o'clock before adding air. Clean the radiator core more often on dusty compaction sites, and drain the fuel water separator regularly, since low-sulfur diesel raises static-ignition risk while fueling.

CP-573E fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
1648-04Fuel injection pump: supply voltage below normal at the pump's electronic control.Corroded or loose pump power/ground connector, a failing voltage/load-protection module near the engine ECM, or a chafed harness run.With key on, check supply voltage at the injection pump connector and inspect the load-protection module and battery cables before condemning the pump.
1648-07Fuel injection pump: mechanical system not responding to ECM commands.Damaged CAN data-link wiring (twisted pair) between the engine ECM and the pump's internal control, or a failed pump-internal controller.Inspect the CAN twisted-pair harness between the engine ECM and the injection pump connector for chafing, corrosion, or an open circuit before replacing the pump.
100-XXEngine oil pressure sensor circuit fault or a low oil pressure reading; exact failure-mode suffix varies with the fault type.Cracked or open oil pressure sensor, low engine oil level, or a damaged sensor connector.Check oil level and test sensor connector pins for continuity first; replace the sensor if it shows an open circuit.
190-08Engine speed/timing sensor: abnormal frequency signal from the crankshaft speed sensor.Sensor air gap out of spec from tone-ring wear or sensor tip erosion, more often than an outright sensor failure.Recheck and reset the sensor air gap against spec before replacing the sensor.
342-XXSecondary engine speed/timing sensor (camshaft) signal fault; works with the primary crank sensor for cold-start timing and cylinder identification.Damaged camshaft sensor or a chafed harness near the sensor.Inspect camshaft sensor wiring and connector and verify air gap before replacement.
174-XXEngine fuel temperature sensor signal lost or erratic.Open or intermittent fuel temperature sensor circuit, or a damaged connector.Check sensor wiring continuity and connector condition; replace the sensor if the circuit is open.
168-XXElectrical system (battery) voltage out of range at the engine ECM.Weak battery, failing alternator/charging circuit, corroded battery cables, or a failed voltage/load-protection module.Load-test the battery and check charging voltage at the ECM connector before replacing the protection module.

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

CP-573E attachments & work tools

Front push/leveling blade

A hydraulically operated push blade mounts to the front of the machine ahead of the drum, used for spreading, backfilling, and rough grading in trench and embankment work. It ties into the machine's auxiliary hydraulic circuit for raise/lower and bolts to a front mounting/bumper group, with bolt-on replaceable cutting edges.

Padfoot / smooth-drum shell kit

The CP-573E is the padfoot-drum member of this compactor family; its CS-573E counterpart runs the same chassis with a smooth drum. Bolt-on curved shell segments convert a smooth drum to padfoot for clay/cohesive soil work, or swap a padfoot shell back to smooth plates for granular fill and finish passes; shells bolt to the drum end rings and need no hydraulic hookup. Drum width for this class runs around 2.1 m (roughly 84 in), though confirm against the exact machine since family-wide spec listings are inconsistent on this figure.

Drum scraper bar

An adjustable scraper bar rides against the drum face to strip soil buildup off the pads or shell. Padfoot scraper tynes and smooth-drum scraper blades bolt to the same bar assembly, so operators swap scraper hardware rather than the whole bar when changing between padfoot and smooth-drum shells.

Operator station: open ROPS canopy vs enclosed cab

Factory build offers an open ROPS/FOPS canopy station or a fully enclosed ROPS cab with heater, air conditioning, sliding door/window, and sun screen. The cab is mounted on a tilting frame for engine-bay service access, and separate wiring/lighting harness kits exist for open-ROPS versus cab-equipped machines.

Guarding options

Available factory guarding includes a vandalism guard group for the operator station and an axle guard group protecting the oscillating rear axle. These are bolt-on protective packages rather than powered work tools and do not require a hydraulic kit.

Lighting and warning packages

Options include front and rear flood/work lamps (including an engine-bay work light) and an amber rotating warning beacon. Lamp and harness kits differ between open-ROPS and cab configurations, so fitment depends on which operator station the machine carries.

Dual-amplitude vibratory drum system

The drum exciter uses a positive-selection eccentric-weight design giving two amplitude/force settings rather than a bolt-on attachment: a lower-amplitude setting for finish or lift compaction and a higher setting for deeper lifts. Centrifugal force and frequency at each setting vary by configuration and source, so verify against the machine's data plate rather than a generic spec sheet.

CP-573E serial number reference

The PIN/serial plate on a CP-573E is a metal tag riveted to the machine frame. It carries the full Product Identification Number; the first three characters are the serial prefix identifying the build block, followed by the sequential unit number. Match the prefix (CEB, ASY, ASZ, or CNN) to the parts or service manual break to confirm which drum, hydraulic, and engine-tier configuration applies to that unit. If the plate is worn or missing, confirm the block through a dealer parts lookup using the full PIN.

ASYCP-573E vibratory compactor, Cat 3056E diesel engine
ASZCP-573E vibratory compactor, Cat 3056E diesel engine
CNNCP-573E vibratory compactor, later Tier 2/Stage II emissions-compliant Cat 3056E ATAAC engine - confirm with dealer

Frequently asked questions

What engine does the Caterpillar CP-573E use?

The CP-573E runs a turbocharged, electronically controlled Cat 3056E diesel rated at roughly 112 kW (150 hp) gross. This engine is shared across the CS/CP 563E-583E family; verify against the engine information plate for the exact rating on a given unit.

What is the operating weight of the CP-573E?

Bare operating weight with a ROPS/FOPS canopy and no blade is about 13,750 kg (30,310 lb). Adding the leveling blade brings it to roughly 13,935 kg (30,720 lb), and a factory cab adds about 325 kg (715 lb) more. Actual weight varies by configuration - blade, cab, and canopy versus cab all shift the total.

What replaced the Caterpillar CP-573E?

Cat retired the 563E-683E soil-compactor numbering in favor of a production-class lineup (roughly CP54 through CP76 and CS equivalents) with different engines and controls. The CP74 sits in a broadly similar weight class to the CP-573E, though it is a different design generation, not a direct parts-interchangeable successor.

What CP-573E owners discuss

What engine is actually in the CP-573E, and how much power does it make?
The CP-573E and its smooth-drum sibling CS-573E run the Cat 3056E ATAAC turbocharged diesel rated around 112 kW (150 hp) gross. That engine is shared across the E-series padfoot/smooth-drum family (563E, 573E, 583E), but it is tuned differently per model — the larger 663E carries a higher-output version of the same base engine, so do not assume its horsepower figure applies here. Confirm the rating against the serial prefix on the machine in hand rather than a sibling model's spec sheet.
The compactor needs the fuel system primed every time before it will start — is that normal?
Recurring priming almost always points to a low-pressure air leak in the fuel circuit rather than an electrical fault. Owners and techs working on the 3056E consistently check the same spots: the lift pump lid gasket, the fuel filter-to-filter-head seal, and the return-line banjo fitting at the transfer pump (it must be the orifice type, not a plain washer). Some shops add an inline check valve just ahead of the lift pump as a stopgap while chasing the actual leak. If bleeding does not hold after those checks, have your dealer verify the low-pressure fuel circuit before returning the machine to service.
Vibration feels weak or drops out on one amplitude setting — what should get checked first?
Start with the cheap items: continuity on the vibratory selector switch, the wiring run to the switch and to the vibrator solenoid valve, and the fuse on the instrument panel. A rough or knocking sound from the drum along with reduced vibrations-per-minute points instead to wear in the drum's weight bearings, which drag the eccentric shaft and can eventually cause it to bind. Those bearings are serviced only as a matched kit to hold correct preload — do not mix a new bearing with a worn one. Because a seized eccentric shaft can damage the drum assembly, have your dealer verify bearing condition before running the vibratory system again.
What typically wears out on the drum and pads with heavy service?
Padfoot shell segments crack and tear at the feet over time; a common shop rule is that once about a quarter of the pads on one side are torn or cracked, the whole shell set on that side gets replaced together rather than patched piecemeal. Cleaner bars against the drum need regular adjustment — if they wear back too far, cohesive soil packs into the drum and compaction quality drops off even though the machine seems to be running fine. In sticky clay, operators keep an eye on scraper/cleaner bar contact and back them off or wet them down if the machine sits idling for a stretch, since dry contact can mark the drum.
Any hydraulic behavior specific to this machine that owners flag?
Overheating on the propel/vibratory hydraulics traces back to a short list of causes reported again and again: low oil level in the tank, a relief valve set too low, a restriction acting like an orifice in a line, or excess mechanical friction from a dragging component such as a worn drum bearing. None of these are unique to the 573E, but the vibratory circuit's duty cycle makes the machine less forgiving of a marginal oil level or a slipping relief setting than a standard propel-only hydraulic system. Relief valve pressure adjustments affect vibratory output and drum-bearing loading, so have your dealer verify the setting rather than adjusting it in the field without a pressure gauge.
Is there a known wear point at the articulation joint?
Yes — pin and bushing wear at the articulation hitch shows up as play or a knock when turning, and it is a recognized inspection point across this E-series padfoot/smooth-drum family after several thousand hours. The joint needs to stay on the grease schedule; components beyond wear limits get replaced as a set to keep the joint tight. Because the articulation joint is a steering and structural connection between the front drum and rear axle, have your dealer verify pin/bushing wear limits rather than eyeballing acceptable play.
What should I check before buying a used CP-573E?
Cold-start the machine and see if it fires without repeated priming — a fuel system that needs coaxing every start suggests an unresolved air leak in the low-pressure circuit. Cycle the vibratory system on both high and low amplitude and listen for smooth operation versus a rough or knocking drum, which flags weight-bearing wear. Inspect the pad/shell condition for cracking (more than about a quarter torn per side is a replacement job) and check the drum for flat spots or out-of-round wear. Work the articulation joint for play and check the hydraulic tank and lines for leaks or discoloration suggesting a history of overheating. Ask for service records, especially anything showing prior drum weight-bearing kit work, since that is one of the costlier jobs on this machine. Given the drum, hydraulic, and articulation checks all touch structural and safety-relevant systems, have your dealer verify condition on all of the above before final purchase.
