Caterpillar 584

Maintenance schedule, common problems & OEM parts breakdown

The Cat 584 is a cut-to-length forestry forwarder, built to carry delimbed logs from the stump to a landing or roadside. It runs a Cat C7 ACERT diesel, a 7.2 L inline-six rated 204 kW (274 hp), meeting Tier 3/Stage IIIA emissions, paired with a forestry-duty hydrostatic drive. Operating weight spans 20,230 kg (44,600 lb) for the standard 584 in 6WD configuration up to 23,088 kg (50,900 lb) for the 584HD, an 8WD sibling on the same platform with a reinforced frame and an extra bogie axle for heavier bunks. Caterpillar introduced the line in 2009 as an 18-to-20-metric-ton forwarder pair, built on cut-to-length engineering it gained when it bought Blount's Prentice forestry business in 2007. Both variants carry an Epsilon X120F80 loader crane with rotator and run Cat's IQAN MDL electronic control system for crane and drivetrain functions.

The 584 and 584HD share engine, cab, and crane hardware; the difference is wheel count and frame reinforcement, not powertrain. The HD's extra axle spreads a heavier bunk load and adds traction on soft or steep ground, while the 6WD stays lighter and more maneuverable for smaller timber sales. Caterpillar never issued a distinct in-house successor: when it sold its skidder, feller buncher, and knuckleboom loader lines to Weiler in 2019, forwarders were left out of that deal, so the 584 family stayed a Cat product rather than passing to a new brand. That continuity keeps Cat dealer parts support and service documentation attached to units already in the field, which matters to buyers shopping the used market or sourcing components for an older machine, since the drivetrain, crane, and control system are still current Cat architecture rather than a discontinued third-party design.

584 fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase (with filter) – Cat C7 ACERTNot published in available factory literature for this chassis. Confirm against dipstick full mark or dealer OMM before service.Cat DEO-ULS (Diesel Engine Oil Ultra Low Sulfur). Use SAE 15W-40 in warm ambient conditions; step down to 10W-30 or 0W-40 for cold-start climates per Cat's engine oil viscosity-by-temperature guidance.
Cooling systemNot published in available factory literature for this chassis. Factory sales literature notes 'enlarged cooling capacities' versus prior forwarder generations but gives no liter figure. Verify at dealer.Cat ELC (Extended Life Coolant), premixed. Where ELC is unavailable, Cat DEAC is the fallback per standard Cat coolant guidance.
Fuel tank255 L (67.3 US gal)Ultra-low sulfur diesel. Switch to a winter-blend or treated fuel below freezing ambient temperatures to prevent gelling.
Hydraulic system reservoir (tank)174 L (46 US gal) reservoir. Total circuit volume including lines and coolers runs higher but is not broken out separately in available literature.Cat HYDO Advanced 10. Factory literature notes the oil-change interval extends to 3000 hours when this fluid is used; consult O&S sampling program for further extension.
Powertrain – hydrostatic drive and 2-speed drop boxNot published as a separate figure. The forwarder uses a closed-loop hydrostatic propel circuit tied into the main hydraulic system; the drop box gear case is a separate, smaller compartment with no public capacity figure.Hydrostatic circuit shares the hydraulic reservoir fluid (Cat HYDO Advanced 10). Drop box gear case takes Cat TDTO, viscosity selected by climate (SAE 10W in cold climates, SAE 30 or 50 in warm climates).
Axle modules / differentials (NAF axle modules, front and rear as equipped)Not published in available factory literature for this chassis. Verify at dealer using serial-specific OMM.Cat TDTO (Transmission/Drivetrain Oil), SAE 50 in warm climates, multigrade TDTO for cold-start regions, consistent with Cat's shared drivetrain-fluid approach for wheeled forestry machines.
Bogie / hub reduction housings (each, where fitted)Not published in available factory literature for this chassis. Verify at dealer.Cat TDTO, matched to the axle/differential fill for the same climate band.
Grease (spec only) – articulation joint, loader pivots, grapple rotator pointsNot applicable (grease points serviced by interval, not by refill volume).NLGI 2 moly-fortified Cat grease (Cat Ultra 5 Moly or Cat Prime Application Grease) for center articulation pins, loader boom pivots, and grapple rotator bearings.

Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the 584 beyond the schedule

Predictive Maintenance & Fluid Analysis

Run S.O.S sampling on C7 ACERT engine oil, the 174 L hydraulic reservoir, and bogie axle oil to catch wear before it costs a pump or axle. Log IQAN MDL fault history and hydrostatic charge-pressure trends rather than waiting for a warning light. Watch the closed-circuit load-sensing crane valves for flow or pressure decay, an early sign of an Epsilon X120F80 crane heading toward a rebuild, and track coolant condition to head off C7 liner and radiator problems.

Corrective & Common Repairs

Typical 584 repairs center on the Epsilon X120F80 crane: worn rotator bushings and pins from constant slewing under load, and cracked wear pads at the boom pivot. Bogie axle seals let go under bark and mud packing, leaking axle oil past the hub. Hydrostatic charge pumps wear faster on machines run through repeated cold starts. Radiators and coolers pack with bark debris and need frequent cleaning, and IQAN MDL harness connectors corrode in wet duty, causing intermittent crane or drive faults.

Overhaul & Rebuild Points

At high hours, expect the hydrostatic drive pumps and motors to need rebuild or replacement first, since they carry full engine power through every load cycle. Bogie axle bearings and planetary final drives wear from constant articulation over rough ground and follow next. The Epsilon crane structure, pins, bushings, and wear pads need periodic rebuild once slop develops in the boom. On the C7 ACERT, plan for injector and turbocharger overhaul as hours climb, alongside cab and ROPS mount refurbishment.

Seasonal & Environment Servicing

Cold-climate logging demands a coolant concentration check and block-heater use before the C7 ACERT sees sub-zero starts, plus more frequent fuel-water separator draining as condensation increases. Change bogie axle oil ahead of spring mud season, when water intrusion past seals is common. In hot, dry duty, service air filters more often against dust and check crane hydraulic oil viscosity across temperature swings. Wet coastal or wetland sites call for closer corrosion checks on axle housings and crane pins.

584 fault codes & troubleshooting

CodeMeaningLikely causeWhat to do
100-01Engine oil pressure critically low (data valid, most-severe low-range fault) - typically paired with an oil pressure shutdown event.Low oil level, plugged oil filter or suction screen, worn oil pump, or a failed oil pressure sensor/wiring.Stop the engine (or confirm it has already shut down), check oil level and filter condition, then verify sensor wiring and connector before restart.
100-17Engine oil pressure below normal at the least-severe warning threshold.Marginal oil level or viscosity, normal warm-idle pressure drop, or early sensor drift.Check oil level and grade, let idle warm up, inspect for external leaks, and monitor the gauge so it does not progress to a derate or shutdown level.
110-00Engine coolant temperature above normal operating range; severity (warning vs. shutdown) depends on which FMI/event pairing is active.Low coolant level, blocked radiator core or debris screen, slipping or failed fan drive, or a faulty coolant temperature sensor.Idle down, check coolant level and clean the radiator/debris screen (common in forestry duty), inspect fan drive engagement, and confirm sensor reading against a manual temperature check.
168-01System (battery) voltage below normal range.Weak or failing battery, loose or corroded ground/main power connection, or low alternator charging output.Load-test the battery, clean and tighten ground and main power connections, then check alternator output with the engine running.
168-00System (battery) voltage above normal range.Alternator/regulator overcharging, or a poor battery ground causing voltage spikes.Check charging system output against spec, inspect grounds, and replace the regulator or alternator if overcharging is confirmed.
190-08Engine speed/timing sensor signal abnormal - erratic frequency, pulse width, or period.Incorrect sensor air gap, a damaged tone-wheel tooth, or a corroded sensor connector.Check the sensor air gap with a feeler gauge, inspect the connector and wiring, and check the tone wheel before replacing the sensor.
102-03Boost (intake manifold) pressure sensor circuit reading above normal, consistent with a short to a high voltage source.Sensor circuit shorted to battery/power, a damaged sensor, or chafed harness wiring.Inspect the sensor connector and harness for a short to power, test sensor supply and signal voltages, and replace the sensor if out of spec.
164-02Injection actuation (hydraulic-electronic unit injector) pressure signal erratic - desired vs. actual injection pressure mismatch.Faulty injection actuation pressure sensor, a failing high-pressure oil pump, injector leakage, or incorrect engine oil level/condition.Check engine oil level and condition first, inspect the IAP sensor and its wiring, then test high-pressure pump output if the sensor and oil check out.

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

584 attachments & work tools

Timber Grapples

Standard grapple is the Epsilon FG37, gripping area about 0.36 m² (3.9 ft²). Optional Epsilon FG43S steps up to about 0.40 m² (4.3 ft²) gripping area for larger or bundled logs. Grapple choice is tied to the factory-fitted Epsilon loader, not a field-swap between arbitrary brands.

Loader / Crane

Factory-fitted Epsilon X120F loader crane gives 8.0 m (315 in) reach with 380-degree slew. Lifting torque is rated at 159 kN·m (111,975 lbf-ft) and slewing torque at 45 kN·m (30,240 lbf-ft). Crane functions are ramped and proportional to cut shock loading on the boom structure.

Rotator / Grapple Mounting

An Epsilon G141 link-rotator sits at the crane tip and carries the grapple, giving continuous rotation plus pendulum action for self-leveling on uneven piles. The mount is a standard forestry link-rotator interface, so any wood grapple sized for the class bolts on without special tooling.

Bunk & Headboard

Standard bunk area is 5.5 m² (59.3 ft²) with moveable load bunks; an optional extended bunk gives 6.25 m² (67.3 ft²) for longer or bulkier loads. The headboard is shock-cushioned at its mounting and hydraulically extendable, with adjustable load-stake spacing to match log length.

Implement Hydraulic Circuit

A variable-displacement axial piston implement pump (about 200 cc/rev) feeds closed-circuit, load-sensing valves dedicated to the crane and grapple. Rated flow is about 284 L/min (75 gal/min) at 21.5 MPa (3,120 psi) working pressure, sized specifically to run the loader/grapple work tool rather than shared construction-attachment circuits.

Tires / Traction Options

Standard fitment on the 6WD machine is 700/70x34 front and 750/55x26.5 rear. A narrower 650/65x26.5 option is available where a tighter carrier width is needed for thinning work. The related 8WD HD variant is documented alongside the 584 in factory literature but uses its own matched tire and bogie arrangement for higher tractive effort; treat wheel/tire specifics as varying by configuration.

Cab Guarding / Operator Protection

The pressurized cab is ROPS/OPS certified to ISO 3471 and ISO 8082, and FOPS Level II certified to ISO 3449 and ISO 8083, standard equipment given the overhead loader/grapple work envelope. Glazing is 12.7 mm (1/2 in) tinted polycarbonate for impact protection from bark, chips, and branch debris during grapple work.

Flotation / Bogie Tracks (aftermarket)

Steel bogie or wheel tracks for soft-ground flotation are common fitment across forwarders in this size class, run over the factory tires. No Cat factory bogie-track option is documented specifically for the 584; fitment and sizing should be verified against tire size and axle rating with the dealer or track supplier.

Frequently asked questions

What engine powers the Caterpillar 584 forwarder?

A Cat C7 ACERT diesel: a 7.2 L inline-six rated 204 kW (274 hp), meeting Tier 3/Stage IIIA emissions. Both the 584 (6WD) and 584HD (8WD) share this same engine; they differ in axle count and frame, not powertrain.

What is the operating weight of the Caterpillar 584?

The standard 584 in 6WD configuration operates at 20,230 kg (44,600 lb). The heavier 584HD, an 8WD version on the same platform, runs 23,088 kg (50,900 lb) with its added axle and reinforced frame.

What replaced the Caterpillar 584 forwarder?

No dedicated Cat successor model exists. When Caterpillar sold its purpose-built skidder, feller buncher, and knuckleboom loader lines to Weiler in 2019, forwarders were left out of that sale, so the 584/584HD family remained Caterpillar's cut-to-length forwarder offering.

What 584 owners discuss

What do operators say about the Cat C7 ACERT engine in the 584 forwarder?
Consensus on the C7 ACERT platform (204 kW / 274 hp in the 584) is that it is strong on power delivery but demands disciplined oil and fuel maintenance. The injectors carry a hydraulic boost fed off engine oil pressure, so thin or contaminated oil shows up first as rough idle or a power dip rather than a dramatic failure. Turbo actuator and wiring-harness connectors at the valve cover are the first things to corrode in a wet, bark-and-needle-laden forestry environment, causing intermittent derates or hard starts. Owners also flag the fuel pump internal bypass valve as a slow-leak point that causes hard cold starts over time. Cracked cylinder heads and crankshaft or rod distress show up on high-hour, poorly maintained units, almost always traced back to skipped oil analysis or extended change intervals. Any suspected crankcase or bottom-end noise should stop the machine immediately and have your dealer verify before continued operation.
How does the hydraulic system hold up under continuous forestry duty?
The load-sensing, pressure-compensated axial piston pump is generally regarded as durable and quiet for the duty cycle. The recurring complaint in forestry use is contamination, not the pump itself: bark fines and needle debris load up the hydraulic oil cooler and case-drain filters faster than the book service interval suggests, so operators in heavy going shorten filter and cooler-cleaning intervals rather than follow the standard chart. Crane and boom pivot bushings take the brunt of grapple twisting loads and are the wear item owners chase most, especially on machines doing a lot of roadside sorting where the boom is worked at full extension. The electric refill pump and vacuum-assisted hydraulic tank are appreciated for keeping oil clean during filter changes, but only if the vacuum seal is actually holding — a weak seal reintroduces the same debris problem it's meant to prevent.
What wear patterns typically show up on the 584's bogies and undercarriage?
The geared bogie axles and rigid front axle (6WD layout) are considered a strong, low-maintenance design for a wheeled forwarder, but the bogie pivot bushings and pins are the wear point that separates a well-kept machine from a neglected one. Machines run on frozen or rocky ground chew through chains faster than those on softer soil, and grease intervals on the bogie pivots need to be tightened up in mud and slush rather than left at the printed interval — skipped greasing shows up as slack, uneven bogie walk before it shows up as measurable bushing wear. Tire and chain condition is one of the more visible tells of how a machine was actually run versus how it looks on paper.
Are there known electrical or sensor quirks with the CAN-bus IQAN control system?
The CAN-Bus IQAN setup with the MDL master display is well liked for on-screen diagnostics, but the recurring gremlin reported is connector corrosion, not the electronics themselves. Moisture and mud working into harness connectors — particularly near the hood tilt hinge and around chassis-to-cab crossover points — produces intermittent fault codes, a dash that blanks or freezes, or a false sensor fault that clears itself once the connector is cleaned and dielectric-greased. Chafed wiring at the hood pivot from repeated tilting for service access is the other common source of nuisance faults. A genuine stored fault tied to engine or hydrostat control, as opposed to a corrosion-related nuisance code, should have your dealer verify before it's dismissed as wiring.
Is there a known engine quirk specific to the C7 ACERT series worth knowing before running the 584 hard?
Yes — the ACERT injection system is sensitive to overheating under sustained load, such as prolonged uphill travel with a full bunk, showing up as a power pull-back rather than a hard shutdown. This is treated as protective behavior rather than a defect, but repeated derates under normal cooling conditions are read as an early warning of a cooling system or sensor problem rather than something to push through.
What should I check before buying a used Cat 584 forwarder?
Cross-check indicated hours against actual bogie bushing play and tire/chain wear — a low-hour machine with sloppy bogies or chewed chains has usually been worked harder than the meter suggests. Pull the IQAN fault log rather than relying on a clear dash, since nuisance corrosion codes tend to reappear under load even after being cleared. Inspect crane and boom pins and bushings for play under a loaded grapple, check for oil-in-coolant or coolant-in-oil cross contamination at the dipstick and radiator cap, and run the hydrostatic drive through its full range under load to feel for hesitation or overheating. Confirm the cab tilt and hood tilt mechanisms operate smoothly, since stiff service access usually means it hasn't been opened in a long time. Any sign of frame or articulation-joint cracking around the oscillation point is a stop-and-inspect item — have your dealer verify structural condition before purchase.
What's the general reputation of the 584 compared to other forwarders in its class?
Cab comfort, sightlines to the load area, and boom control feel are consistently praised, and the machine is regarded as competitive rather than exceptional against other brands in the same weight class — solid, not remarkable. The most common caveat is that reliability tracks maintenance discipline closely on this platform: well-serviced units run long and hard, while units where oil changes, filter service, and bogie greasing were stretched past interval show engine and undercarriage problems well ahead of their peers.

Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
