Caterpillar CS-573
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar CS-573 is a single-drum vibratory soil compactor, not an asphalt paving roller; the padfoot version of the same chassis is sold as the CP-573. The base CS-573 entered the range around 1995 with a Cat 3116 direct-injection diesel rated near 97 kW (130 hp). The C-series carried the same 3116 block. The CS-573D moved to a turbocharged 3116T rated roughly 114-115 kW (153-155 hp), and the CS-573E, built through the mid-2000s, switched to the air-to-air aftercooled Cat 3056E rated around 112 kW (150 hp). Operating weight across the family runs roughly 13.2 to 13.9 tonnes (29,000-30,700 lb) depending on generation and fitted options. All generations share a single steel drum up front, 2135 x 1524 mm (84 x 60 in), riding ahead of a rubber-tired, articulated rear axle that handles steering and propulsion. A bolt-on leveling blade and an interchangeable padfoot shell kit were offered as configuration options over the smooth drum.
Across the base, C, D, and E generations, Caterpillar kept the drum, chassis, and articulated steering layout largely the same and concentrated changes on the engine and its emissions and power package: the naturally aspirated-to-turbocharged 3116 gave way to the 3116T for more compaction force, then to the ATAAC 3056E for steadier power and cleaner combustion. Fluid specifications and the vibratory drivetrain stayed close enough across generations that many wear items interchange within the family, but eccentric weight housings, drum bearings, and final drives were revised between series and should be matched to serial prefix, not model name alone. Caterpillar retired the three-digit numbering after the E-series in favor of B-series and later tonnage-based compactor names, so no CS-573-badged machine has been built new in close to two decades. That puts the CS-573 squarely in the used-equipment and parts-support market today: a mechanically simple, tonnage-class soil compactor that keeps running on straightforward maintenance and cross-generation parts interchange long after Caterpillar moved its current lineup to different model names.

Servicing the CS-573 beyond the schedule
Predictive Maintenance and Fluid Analysis
Run the OMM's sampling program: pull an engine oil sample every 250 hours, and rear axle, hydraulic, and vibratory-support oil samples every 500 hours, tracking wear metals against the 3116, 3116T, or 3056E baseline for your generation. Trend coolant samples at 250 hours (level 1) and annually (level 2), since these engines run ELC-filled cooling systems long-term. Watch axle and drum final-drive oil analysis closely: the rubber-tired rear axle and drum planetary carry the compaction loads and show wear before external symptoms appear.
Corrective and Common Repairs
Most field issues trace to the vibratory drivetrain and rear axle: worn isolation mounts (inspect every 250 hours, replace as a set if multiple are cracked), leaking drum scrapers, and steering cylinder wear from the articulated joint. On D and E engines, check turbocharger and aftercooler seals for boost leaks that erode compaction force. Fuel system water separators and primary filters need frequent draining given typical dusty jobsite fuel handling on these older single-drum units.
Overhaul and Rebuild Points
At major overhaul, inspect the eccentric weight housing and its oil (changed every 3000 hours or 3 years) for bearing wear that causes amplitude loss, and check the crankshaft vibration damper every 2000 hours or 2 years for bond separation. Drum bearings, final drive planetaries on both the drum and rear axle, and the articulation hitch pin bushings are the other high-wear points worth budgeting for on a CS-573 nearing or past its second engine overhaul interval.
Seasonal and Environment Servicing
Before winter lay-up, verify ELC coolant condition (extend at 6000 hours or 3 years, full change at 12,000 hours or 6 years) and confirm engine oil viscosity matches cold-start temperatures per the OMM's grade chart. In hot, dusty compaction work, service the primary and secondary engine air filter elements more often than the 250-hour baseline and clean the radiator core to prevent overheating under sustained vibratory load. Drain fuel tank water and sediment weekly in humid or wet-season conditions to protect the injection system.
CS-573 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| CID 100 FMI 1 | Engine oil pressure sensor circuit — pressure reading below normal range for current engine speed | Low oil level, worn oil pump, plugged suction screen, or a faulty oil pressure sensor/wiring | Stop engine, check oil level and condition first, then verify sensor wiring before condemning the pump |
| CID 110 FMI 0 | Engine coolant temperature above normal operating range | Low coolant, blocked radiator fins, slipping or failed fan drive, or thermostat stuck closed | Idle to cool, check coolant level and radiator core for debris, inspect fan drive belt/clutch |
| CID 111 FMI 3/4 | Engine coolant level sensor reading out of range (voltage above or below normal) | Low coolant in the sight glass/sensor tube, air in the cooling system, or a faulty level probe | Check coolant level when cool, inspect for external leaks, test sensor connector and wiring |
| CID 168 FMI 2 | Electrical system (battery/charging) voltage erratic, intermittent, or incorrect | Loose or corroded battery terminals, failing alternator, or a chafed harness ground | Load-test the battery, check alternator output at idle and rated speed, clean/tighten all grounds |
| CID 174 FMI 0 | Fuel temperature above normal | Restricted fuel return line, high ambient/engine bay temperature, or a failing fuel cooler where fitted | Check fuel return routing and cooler for blockage, confirm engine bay airflow is not obstructed |
| CID 190 FMI 2 | Engine speed/timing signal erratic or intermittent | Damaged speed/timing sensor, worn gear teeth at the sensor location, or a loose sensor connector | Inspect sensor air gap and mounting, check harness connector for corrosion, retest at operating temperature |
| CID 1 FMI 5 | Injector solenoid/actuator circuit open — no continuity detected | Broken injector wiring, failed injector solenoid, or a disconnected harness pin at the valve cover connector | Check harness continuity from ECM to injector, inspect valve cover pass-through connector for moisture damage |
| Hydraulic oil temperature warning lamp | Hydraulic system oil temperature has exceeded the safe operating threshold | Low hydraulic oil level, clogged oil cooler fins, or sustained high-load operation in hot ambient conditions | Idle down, check hydraulic oil level and cooler core for debris, let system cool before resuming work |
| Vibratory system malfunction lamp | Drum vibratory (piston motor/pump) circuit or hydraulic supply fault detected | Faulty vibratory on/off solenoid, low charge pressure to the piston pump, or a wiring fault at the operator control switch | Check the vibratory switch and solenoid wiring, verify charge pump pressure, inspect connectors for corrosion |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
CS-573 attachments & work tools
Machine type and series
The CS-573 is a single-drum vibratory soil compactor, not an asphalt paving compactor; Caterpillar's paving/asphalt line uses the CB-series designation instead. The CS-573 name spans a mid-1990s base build, a CS-573D generation, and a CS-573E generation (2002-2007), and specs shift noticeably between them, so confirm generation before matching options.
Padfoot counterpart (CP-573)
The padfoot-drum version on the same chassis is sold as the CP-573; it shares the frame, engine, and running gear with the CS-573 but uses a shell-type padfoot drum for cohesive/clay soils instead of the CS smooth drum. Choosing CS vs CP is effectively the main work-tool decision for this frame size, fixed at build rather than swapped through a quick-attach coupler.
Drum dimensions for this class
Across the D and E generations the drum measures about 2135 mm wide by 1524 mm diameter (84 in x 60 in), consistent for this size class. Static linear load on the E-series works out to roughly 9.9 kN per meter of drum width (about 566 lb/in).
Vibratory system
A dual-amplitude, dual-frequency vibratory system is standard for this class, with frequency around 1850-1915 vpm (30.8-31.9 Hz) depending on generation. Centrifugal force runs roughly 125-133 kN (28,100-29,900 lb) on low amplitude up to about 249-266 kN (56,000-59,800 lb) on high amplitude; amplitude is an operator-selected setting, not a separate work tool.
Coupler / mounting system
This compactor class has no field quick-coupler for exchanging work tools; the drum itself (smooth or padfoot) is the fixed work-tool interface. Where a smooth-drum machine is converted in the field, it takes a bolt-on padfoot shell kit sized to the drum shell rather than a hydraulic quick-coupler mount.
Operator protection / cab configuration
Factory configurations for this compactor family include an open ROPS/FOPS canopy or an enclosed ROPS/FOPS cab, with air conditioning offered on the cab version. Documentation confirming exact availability is stronger for neighboring family members (CS-563/CP-563 and later CS/CP models) than for the CS-573 directly, so confirm by serial range with a dealer.
Ballast / weight kits
Cat's CS/CP compactor family of this era offers ballast weight kits, generally in a roughly 100-540 kg range across the lineup, to fine-tune operating weight and compaction effort. Specific kit availability for the CS-573 itself is not separately documented in available literature and should be verified with a dealer.
Drum scraper / cleaning equipment
A spring-loaded, non-metallic scraper bar riding against the drum to prevent soil buildup is standard equipment across Caterpillar's single-drum smooth-drum compactor lineage. This is factory-fitted rather than an optional work tool; confirm exact standard-equipment wording for the legacy CS-573 serial range against the era-specific spec sheet.
Engine and powertrain by generation
Engine spec changes by generation: the CS-573D-era machine uses a Cat 3116T rated around 114 kW (153 hp) gross, while the CS-573E (2002-2007) uses a Cat 3056E rated about 107 kW net / 112 kW gross (143.5/150.2 hp). Match any hydraulic-driven attachment or hydraulic-kit spec to the specific generation, since available pump output differs between the 3116 and 3056E platforms.

CS-573 serial number reference
The serial/PIN plate on CS-573 series compactors is mounted on the main frame, generally near the operator platform or front articulation area, and is also stamped into the frame itself as a backup. Older-format Cat serials on this compactor line read as a 3-character prefix (tied to model and build block) followed by a sequence number, for example CEB followed by its sequence. Read the full string off the plate rather than relying on the model tag alone, since several distinct prefixes can apply across the production run of what is sold as the same base model.
| Prefix | Identifies | Notes |
|---|---|---|
| 8PK | CS-573 (first-generation) smooth-drum vibratory soil compactor | Cat 3116 diesel, mid-1990s production window (exact year unconfirmed). Prefix appears on the CS-531/CP-533/CS-533/CS-573/CS-583 shared electrical schematic set rather than on a CS-573-only document, so cross-check the full PIN on the plate before ordering parts against this prefix alone. Confirm with dealer. |
| 6LN | CS-573C smooth-drum vibratory soil compactor | C-series update of the base CS-573, Cat 3116 diesel. Prefix ties directly to CS-573C on parts and service-manual listings that name both the model and the prefix together. |
| 2YZ | CS-573D smooth-drum vibratory soil compactor | D-series update, Cat 3116T turbocharged diesel. Prefix ties directly to CS-573D on parts, service, and hydraulic-schematic listings that name both the model and the prefix together. |
| CEB | CS-573E / CP-573E vibratory compactor (E-series) | Cat 3056E ATAAC turbocharged diesel. Prefix covers both the smooth-drum CS-573E and pad-foot CP-573E build, same base machine, same parts manual. |
| CNN | CS-573E / CP-573E vibratory compactor (E-series) | Later serial break within the E-series production run, same Cat 3056E ATAAC engine as the CEB-prefix units. |
| ASY | CS-573E / CP-573E vibratory compactor (E-series) | Serial break covering the hydraulic-system section of the parts breakdown for this model, same Cat 3056E ATAAC engine. |
| ASZ | CS-573E / CP-573E vibratory compactor (E-series) | Serial break covering the service-equipment-and-supplies section of the parts breakdown for this model, same Cat 3056E ATAAC engine. |
Frequently asked questions
What engine does the Caterpillar CS-573 use?
It depends on the generation. The original CS-573 (about 1995) used a Cat 3116 direct-injection diesel rated near 97 kW (130 hp). The CS-573D moved to a turbocharged 3116T rated roughly 114-115 kW (153-155 hp), and the CS-573E switched to the air-to-air aftercooled Cat 3056E rated around 112 kW (150 hp). Match repair parts to the machine's serial prefix, not just the model name, since internals changed between generations.
What is the operating weight of the Caterpillar CS-573?
Operating weight runs roughly 13.2 to 13.9 tonnes (29,000-30,700 lb), depending on generation and configuration. A base machine with a ROPS canopy sits at the lower end; adding a cab, leveling blade, or padfoot shell kit pushes it toward the top of that range.
What replaced the Caterpillar CS-573?
Caterpillar never issued a documented one-for-one successor under the CS-573 name. Production of the three-digit numbered single-drum compactors ended with the E-series by the mid-to-late 2000s, after which Caterpillar moved to B-series naming and then to today's tonnage-based CS model numbers. A roughly 13-14 tonne single-drum compactor in the current lineup is the nearest weight-class equivalent, but there is no confirmed direct model-for-model replacement.
What CS-573 owners discuss
Is the CS-573 really an asphalt paving compactor, and does the engine change across the model's life?
No. The CS-573 is a single-drum vibratory soil compactor, built for embankment and subgrade work, not mat finishing. The padfoot version of this same chassis is sold as the CP-573; don't cross-reference asphalt-compactor data onto a CS-573. Powertrain shifts with the generation: the original CS-573 (mid-1990s) runs the Cat 3116 DIT rated around 97 kW (130 hp). The CS-573D update carries the turbocharged 3116T, rated in the 114-115 kW (153-155 hp) range depending on source. The CS-573E (roughly early-to-late 2000s) switches to the Cat 3056E ATAAC, gross rated near 112 kW (150 hp). Read the serial plate before assuming engine family from the model suffix alone - parts and tuning are not interchangeable across the three.
What's the failure operators bring up most on the CS-573E generation?
Drum drive planetary lockup. The planetary in the drum drive can seize, and once it does the machine won't move in either forward or reverse. The diagnostic path is to check drum drive planetary brake release pressure - spec'd above roughly 1300 kPa (189 psi). Low release pressure lets the brake drag, which cooks the planetary over time rather than failing it outright. This is a drivetrain safety item since a locked planetary can strand the machine mid-slope. Have your dealer verify brake release pressure and planetary condition before returning the machine to work.
What are the known quirks of the Cat 3116 engine used in the base CS-573 and CS-573D?
Injector cup failure is the classic 3116 complaint - it mimics a blown head gasket or ring/blowby problem, so don't jump straight to a top-end teardown without checking cups first. The block uses dry sleeves, so a bad liner means boring and sleeving rather than a simple swap. The HEUI fuel system is sensitive to a clogged fuel tank vent, which starves the pump and scores the housing; stop solenoids are a known weak point for no-start complaints. Water pump and oil cooler seepage shows up often enough to be considered routine wear rather than a red flag. Valve drop is reported on older, high-hour units - listen for a knock change and check valve lash history.
Where does undercarriage and vibratory-system wear typically show up on this drum type?
The rubber drum isolator mounts are the main wear item - they isolate vibration between the drum yoke and frame and get replaced as a routine service part once they crack or soften with age; soft mounts show up as increased cab/frame vibration and reduced compaction output. Also check the vibratory eccentric shaft bearings: if these are damaged the eccentric weight shaft can't turn freely, which kills vibratory force even though the exciter still runs. Propel tire sizing on the D-series runs 23.1 x 26 - inspect for uneven wear that points to a propel or steering alignment issue rather than just tire age.
What electrical or sensor problems come up on this compactor family?
The CS-573 shares its wiring architecture with the CS-531/533/583 group, so troubleshooting habits carry across the family. The engine speed/timing circuit is a recurring source of hard-to-pin-down running or starting complaints - there are two sensors (a primary on the crankshaft gear, a secondary on the camshaft gear), and the actual fault is more often harness abrasion, a pinched wire, or a corroded connector than the sensor element itself. Chase the wiring back to the ECM before condemning a sensor. This circuit affects starting and engine timing, so have your dealer verify wiring integrity and sensor readings before returning the machine to service.
What propel or hydrostatic drive symptoms show up, and what usually causes them?
Creeping when stationary, moving in only one direction, or sluggish propel response trace back to the hydrostatic pump's speed-sensing valve sticking or seizing, or to low charge pressure. The pump has dedicated test ports for speed-sensing pressure and charge pressure, and charge pressure spec shifts with engine rpm, so check it at the correct speed rather than at idle. Fine metal or glitter in the hydraulic filter is the tell for a failing pump or drive component and calls for a full drive teardown rather than a filter change and hope.
What should I check before buying a used CS-573?
Start at the serial plate to confirm the exact generation and engine - 3116 DIT, 3116T, or 3056E - since parts support and expected power differ across them and operating weight varies roughly 13.2-13.8 t (29,000-30,400 lb) by configuration. Run the engine and watch for smoke, blow-by, and any HEUI-related hard starting. Inspect the drum isolator mounts for cracking and check drum bearing play by hand. Cycle propel in both directions and under vibration to rule out planetary lockup or hydrostatic pump weakness, and pull the hydraulic filter to look for metal. Ask for service records on the vibratory system and drive - both are the costly repairs on this class of machine. Have your dealer run a full inspection, including brake release pressure and hydrostatic charge pressure, before you commit to a purchase with unknown maintenance history.
