Caterpillar AD45
Maintenance schedule, common problems & OEM parts breakdown
The Cat AD45 is a 45-tonne-class underground articulated haul truck built for hard-rock and coal mine production hauling. Early BKZ-prefix trucks, in production from around 2000, ran the mechanical Cat 3408E through a seven-speed powershift transmission. Caterpillar redesigned the line as the AD45B, then reintroduced the AD45 name for the current J4W-prefix generation, in delivery since early 2020. The current AD45 runs the Cat C18, an 18.1 L six-cylinder diesel, offered in VR (ventilation-reduced), Tier 3/Stage IIIA-equivalent, and Stage V configurations rated 433-447 kW (581-599 hp) gross. Gross machine mass runs 88,820-89,250 kg (195,810-196,765 lb) against a nominal payload of 45,000 kg (99,208 lb), with standard, alternate, and ejector dump body options.
Across generations the biggest change is emissions and fuel control: mechanical injection on the early 3408E gave way to the C18's electronic MEUI system, and the current AD45 adds VR and Stage V engine options unavailable on the AD45B. Caterpillar's own Stage V retrofit program treats the AD45B explicitly as the previous model, and the current AD45 retains its seven-speed powershift, differentials, final drives, and wet-disc brake package, so driveline parts carry across both trucks. That shared driveline is why the used and parts market matters here: the bare AD45 name spans two unrelated engine eras (BKZ-prefix 3408E trucks and J4W-prefix C18 trucks), so buyers and parts counters need to confirm serial prefix and engine before cross-referencing components, while the AD45B-to-AD45 driveline continuity keeps a wide population of transmission, differential, and brake parts interchangeable within the C18 era.

AD45 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) | 64 L (16.9 US gal) | Cat DEO-ULS (Diesel Engine Oil, Ultra Low Sulfur) multigrade. Grade by ambient temperature per the standard Cat engine oil chart: full-synthetic 0W-40/5W-40 for cold-start ranges, 10W-30 for a wide general-duty range, 15W-40 for sustained warm ambient. Confirm the exact grade against the cold-weather chart for the specific serial range. |
| Cooling system | 85 L (22.5 US gal) | Cat ELC (Extended Life Coolant), factory premix formulation. Extended-life coolant/antifreeze; do not mix with conventional green coolant. |
| Fuel tank | 764 L (201.8 US gal) | Ultra-low-sulfur diesel meeting Cat's diesel fuel specification. Biodiesel blends are limited per Cat's aftertreatment guidance on Stage V/Tier 4 Final engines. |
| Transmission (powershift) | 60 L (15.9 US gal) | Cat TDTO (Transmission/Drive Train Oil). Where ambient swings are wide, the TDTO-TMS multi-season blend is used instead of single-season TDTO. |
| Front differential and final drives | 77 L (20.3 US gal) | Cat TDTO, same grade selection as the transmission fill. |
| Rear differential and final drives | 83 L (21.9 US gal) | Cat TDTO, same grade selection as the transmission fill. |
| Hydraulic system and tank | 266 L (70.3 US gal) | Cat TDTO, which fully qualifies for Cat hydraulic systems, or Cat HYDO Advanced where the machine option calls for a dedicated hydraulic-only fluid. Grade by climate the same as the drivetrain fill; verify which of the two the OMM specifies for a given serial/option build. |
| Grease (spec only, no reservoir capacity) | not applicable - lubricated at grease points, no fill capacity | NLGI 2 Cat grease for pins, bushings, articulation joint, and steering linkage - Cat Advanced 3Moly/5Moly grease or Cat Extreme Application (XA) grease depending on the duty point. |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the AD45 beyond the schedule
Predictive Maintenance & Fluid Analysis
Run Cat S·O·S sampling on the C18 engine, seven-speed powershift/torque converter, front and rear differentials, final drives, and hydraulic tank every 250 hours to catch wear metals and coolant intrusion before they reach the wet-disc brakes or planetary final drives. Track Truck Payload Measurement System trend data for overload patterns that accelerate frame and hitch wear. On VR-equipped engines, monitor aftertreatment soot loading between services so derated performance doesn't get mistaken for a driveline fault.
Corrective & Common Repairs
Expect wheel-end brake pack wear across all four corners of the enclosed wet-disc oil-cooled system, especially on trucks running steep ramps with heavy retarder use. Check the SAHR parking brake for slow release and the torque converter lockup solenoid for delayed engagement when shift complaints come in. Dual fuel tanks mean checking both water separators, not just one, after fouled-fuel events. Articulation and oscillation hitch pins loosen with hour accumulation and show up first as steering wander or uneven tire wear.
Overhaul & Rebuild Points
Plan planetary final drive and differential rebuilds off the oil-analysis wear-metal trend rather than a fixed hour number; sudden metal counts point to bearing or gear failure well before symptoms show. Torque converter and transmission clutch packs typically come due for overhaul alongside a full four-corner brake pack rebuild once wet-disc wear indicators bottom out. Because the current AD45 retains the AD45B driveline, rebuilt transmission, differential, and brake assemblies from either truck generation interchange, which widens the used-parts pool for these overhauls.
Seasonal & Environment Servicing
Underground haulage keeps the AD45 out of weather, but it doesn't escape environment. High ambient heat and humidity at depth load the cooling system and the oil-cooled brakes, so check coolant condition and radiator core packing more often in hot, poorly ventilated headings. Fine rock dust shortens engine air filter life and adds to VR aftertreatment soot loading. Wet mine water and acidic runoff attack wheel-end seals and electrical connectors faster than a surface duty cycle, so inspect seals and harnesses on a tightened schedule in wet workings.

AD45 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 100-3 / 100-4 | Engine oil pressure sensor circuit signal is outside the valid voltage range (open circuit, short to power, or short to ground). | Damaged sensor, corroded connector pins, or chafed harness wiring, often from underground moisture and dust ingress. | Inspect the sensor connector and harness for damage or corrosion before condemning the sensor; verify the signal with a diagnostic tool, then test or replace the sensor. |
| E360 / 100-1 | Actual engine oil pressure has dropped below the normal operating threshold for current engine speed; this is a real condition event, not a sensor wiring fault. | Low oil level, worn oil pump, plugged oil filter, or internal engine wear. | Shut the engine down as soon as it is safe, check oil level and look for external leaks, and inspect the filter before restarting; do not continue operating on this warning. |
| 110-3 / 110-4 | Engine coolant temperature sensor circuit signal is outside the valid voltage range. | Sensor failure, corroded connector, or damaged wiring. | Inspect the connector and harness, check sensor resistance against spec, and replace the sensor if it is out of range. |
| E361 / 110-16 | Actual coolant temperature has exceeded the normal operating range; a real overheat condition rather than a sensor fault. | Low coolant level, blocked radiator core, cooling fan drive fault, stuck thermostat, or sustained overload in high-ambient underground drifts. | Reduce load and let the engine idle to cool; check coolant level and radiator for blockage or leaks before resuming full load. |
| 168-3 / 168-4 | ECM supply (battery/charging system) voltage is reading above or below the normal operating range. | Weak or failing battery, charging system fault, corroded battery terminals, or a loose ground strap. | Check battery state of charge and alternator output, and inspect all ground connections and terminals for corrosion. |
| 190-8 | Primary engine speed/timing sensor signal is erratic or outside the expected frequency pattern. | Damaged sensor, incorrect sensor air gap, debris on the timing wheel, or a wiring fault. | Check sensor air gap and mounting, inspect wiring for damage, and cross-check against the secondary speed sensor before replacing parts. |
| 2526-3 / 2526-4 | Engine air inlet (intake manifold) temperature sensor circuit signal is outside the valid voltage range. | Sensor failure or connector corrosion, aggravated by moisture and dust common in underground service. | Inspect the connector for moisture ingress and corrosion, test the sensor, and repair the harness or replace the sensor as needed. |
| 1785-3 / 1785-4 | Intake manifold (boost/turbo) absolute pressure sensor circuit signal is outside the valid voltage range. | Sensor fault, a pinched or blocked sense line, or a damaged connector. | Check the sense line for blockage or damage, inspect the connector, then test or replace the sensor. |
| 3547-3 | Water-in-fuel sensor circuit signal is above the normal voltage range, or the sensor has detected water contamination in the fuel/water separator. | Sensor circuit fault, or genuine water and condensation buildup in the fuel-water separator bowl, common with underground fuel handling. | Drain the fuel-water separator, check the sensor connector, and verify fuel quality at the source. |
| 3130-3 / 3130-4 | Aftertreatment DEF tank level sensor circuit signal is outside the valid voltage range; applies to Stage V aftertreatment-equipped units only. | Sensor fault, wiring damage, or a contaminated tank sender. | Inspect the DEF tank sender connector, verify DEF quality and level, and consult the dealer if active regeneration is inhibited. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
AD45 attachments & work tools
Dump body
Standard body style offered in three capacities: 18.0 m³ (23.5 yd³), 21.3 m³ (27.9 yd³), and 25.1 m³ (32.8 yd³). It mounts on the chassis subframe with body retaining pins and is raised and lowered by single-stage hoist cylinders, with raise/lower cycle times in the 15-16 second raise and about 21 second lower range depending on configuration.
Ejector body
Alternative body style at roughly 22.9 m³ (30.0 yd³) capacity, interchangeable with the dump body on the same chassis and mounting points. A hydraulic ram drives an ejector blade rearward through the tub to push the load out a rear gate instead of tilting the box, which keeps the center of gravity low for low-clearance underground haul roads and unstable ground.
Body wear protection
Dump and ejector bodies accept bolt-in body liners around 10 mm (0.4 in) thick and external wear plates around 16 mm (0.62 in) for impact and abrasion protection. Ejector-body tubs also take separate wear strips along the pusher-plate edge and full tub sidewalls.
Tires and rims
Tire and rim selection is a mandatory attachment choice on the machine price list rather than a fixed standard fitment; base machine pricing covers a tubeless rim allowance only. Standard fitment and quoted travel speeds are based on 29.5 R29 radial tires.
Mine transfer ready kit
Optional tack-welded front frame, dump body, and ejector body prepared for underground component transfer, allowing a truck to be broken down into sections and moved through shaft or decline access without full structural rework.
Cab and guarding
An enclosed ROPS/FOPS cab with pressurization and filtration is offered for protection against underground dust and rockfall, with air conditioning, heater, dome light, and a radio-ready compartment offered as cab options.
Fire suppression
A wet-chemical fire suppression system covering the engine and hydraulic tank areas is offered, paired with a manual pull station and dedicated engine-shutdown and suppression-activation switches in the operator station.
Lubrication system
Automatic or centralized lubrication is offered for chassis and body pivot points, with routing that differs slightly between the dump-body and ejector-body configurations.
Camera and visibility package
Optional reverse-facing and cab loading cameras improve operator visibility around the body; a further right-side camera is offered on later Stage V-configured trucks for added blind-spot coverage.
Payload measurement system
An optional Truck Payload Measurement System logs load-cycle weight data at each dump cycle and can display it on scoreboards mounted on both sides of the truck for the loading-unit operator to read in real time.
Battery isolation and shutdown
Ground-level battery isolation is offered in combination with an in-cab isolation switch, an engine-shutdown switch, or both, giving several levels of electrical lockout for underground service work.
Service tooling
Dealer-supplied service tooling for this class includes collet jacking bolts, a diagnostics box, hoist-cylinder supports for body removal, and a brake-wear gauge, referenced in the parts manual rather than sold as machine-mounted attachments.

AD45 serial number reference
The PIN plate on the AD45 is a riveted metal tag on the main frame, following standard Cat practice, often backed by a number stamped directly into the frame nearby in case the plate is lost. The exact plate position for this specific model is not documented in public sources - check the cab access area and frame rails near the articulation joint, and confirm with your dealer if the plate is missing or unreadable. Read the first three characters of the stamped serial as the prefix, which identifies the model and build series; the following five digits are the sequential unit number within that block. On a full 17-character PIN, the same 3-character prefix plus unit number appears in the last eight characters.
| Prefix | Identifies | Notes |
|---|---|---|
| BKZ | Original AD45 generation (pre-AD45B design) | Serial prefix for the earlier-generation Cat AD45 underground articulated truck, fitted with the Cat 3408E diesel and a seven-speed planetary powershift transmission. The AD45 parts catalog for this range starts at BKZ00181-up. Field units under this prefix show very high accumulated service hours, consistent with a production start around 2000. This generation was later succeeded by the AD45B model line. Exact model-year cutoffs and plant location are not documented in public sources - confirm exact build years with your dealer. |
| J4W | Current AD45 generation, redesigned line after AD45B (Stage V) | Serial prefix for the current Cat AD45, a redesigned underground articulated truck reintroduced after the AD45B and announced for delivery starting in early 2020. Fitted with the Cat C18 engine and seven-speed planetary powershift transmission, offered in an EU Stage V emissions configuration and in a lower-emission/ventilation-reduction configuration for mines that do not require Stage V. Some resale listings tag J4W-prefixed units under the older 'AD45B' name, but the factory-stamped PIN itself carries the AD45 model code. The same prefix block is also seen under dealer stock designations such as 'AD45-03' for otherwise identical machines. |
Frequently asked questions
What engine does the Cat AD45 use?
It depends on era. Early BKZ-prefix trucks, built from around 2000, ran the mechanical Cat 3408E through a seven-speed powershift transmission. The current AD45 (J4W-prefix, in delivery since early 2020) runs the Cat C18, an 18.1 L six-cylinder diesel, offered in VR (ventilation-reduced), Tier 3/Stage IIIA-equivalent, and Stage V configurations, with gross power from about 433 to 447 kW (581-599 hp) depending on configuration.
What is the AD45's operating weight?
Gross machine mass runs about 88,820-89,250 kg (195,810-196,765 lb) depending on configuration and series, against a nominal payload rating of 45,000 kg (99,208 lb).
What replaced the Cat AD45?
The bare "AD45" name has been used twice. Caterpillar redesigned the original 3408E-powered AD45 into the AD45B, then brought the AD45 name back for the current C18-powered generation, which replaced the AD45B while carrying over its driveline and adding a Stage V engine option. No newer model has superseded the current AD45; it remains Cat's production 45-tonne-class underground truck.
What AD45 owners discuss
Has the engine on the AD45 changed across its production run, and does it matter for parts and service?
Yes. Early-production trucks, carrying the BKZ serial prefix, ran the mechanical Cat 3408E diesel. Production moved to the Cat C18 afterward, using a mechanically actuated electronic unit injection (MEUI) fuel system paired with a planetary powershift transmission. Bore and stroke on the C18 are 145 mm x 183 mm (5.7 in x 7.2 in), displacement 18.1 L. Rated output varies by configuration/series: Tier 3/Stage IIIA-equivalent and ventilation-reduction (VR) tunes sit around 433 kW (581 hp), while the current Stage V version is rated higher, near 446 kW (598 hp). Treat the 3408E and C18 as two different engine families under the same model name. Confirm which one is actually fitted before ordering filters, injectors, or ECM-dependent parts, since the electronic engine carries its own service software and diagnostic connector that the mechanical one does not.
What do operators say about how the C18 handles underground, heat-wise?
The recurring theme is that these trucks run their engines close to the output ceiling to hit rated payload and cycle-time targets, and that shows up as extra heat load in the heading compared to a similarly sized loader engine. That drives up ventilation demand on the section, which crews plan around rather than treat as a fault. A ventilation-reduction (VR) engine calibration is offered specifically to soften this, so heat complaints on an older non-VR unit are not necessarily unusual for the class. If ambient heat in a specific heading is a real operational problem, ask your dealer whether a VR update or aftertreatment change is available for that serial range.
What causes retarder overheating on long grades, and how is it usually fixed?
Retarder overheating on a descent is almost always cooling flow restriction or the retarder being worked harder than the grade calls for, not a worn retarder itself. Field fixes, in order: confirm the haul grade is within the machine's rated limit before the descent, inspect the retarder oil cooler core for packed dust and clean it with low-pressure air from the clean side outward, then check the retarder cooling circuit oil level and filter condition. The service brakes and retarder share oil-cooled multiple-disc brakes at each wheel end, so persistent heat complaints downhill often trace back to a cooling circuit issue rather than pad wear. Because this system is safety-critical on grade, have your dealer verify cooling flow and brake condition before returning the truck to a heavy haul road.
What undercarriage and wear patterns are typical for this class of underground truck?
The articulation hitch, suspension cylinders, and tires take the brunt of the wear in this application. Pin and bushing wear at the articulation joint is driven mainly by how abrasive the muck and haul road are, not by hours alone, so wear life swings widely between sites. Independent variable-rebound suspension cylinders are meant to soak up haul road shock and extend frame and tire life, but a cylinder losing rebound damping shows up first as accelerated tire wear and a rougher ride, not as an obvious leak. Wet, oil-cooled brakes are sealed against outside dirt by design, but underground water spray and pooled water can still get in through worn shaft or housing seals; once that happens, moisture accelerates oxidation and corrosion inside the brake pack faster than it shows up in a routine oil-level check. Because brake condition is safety-critical, have your dealer verify wet brake oil condition and seal integrity on a schedule rather than waiting for a symptom.
What electrical and sensor issues come up in the field?
Coolant level sensor circuits are a recurring nuisance point. The sensor runs off a low-voltage supply from the engine ECM, and a corroded connector or chafed harness in that circuit can trigger a false low-coolant warning even with a full system. It's worth separating a hardware fault code (a sensor reading out of range or an open circuit) from an event code tied to an actual operating condition, such as a genuine high coolant temperature event that forces a derate or shutdown regardless of whether the sensor itself is healthy. A scan with the factory diagnostic tool sorts the two quickly. Any code that is actively derating or shutting the engine down should be treated as a stop-and-diagnose situation; have your dealer verify the fault before continuing to run the truck.
What do experienced mechanics say about parts and service support for this truck line?
The general feedback on Cat's underground articulated truck line, of which the AD45 is part, is that the trucks themselves are solid, but parts backup can lag with longer lead times than owners expect for basic wear and service items. Sites running these trucks tend to keep their own local stock of common consumables and wear parts rather than order against need, and budget extra downtime around parts availability during a rebuild or unscheduled repair. This is a supply-chain observation more than a design flaw in the machine.
What should you check when buying a used AD45?
Start by identifying the serial prefix and confirming which engine is actually fitted, since 3408E-era and C18-era trucks are not interchangeable on service parts or diagnostic tools. Pull the fault and event code history with the factory diagnostic tool rather than trusting the dash alone. Check hours against any documented powertrain rebuild; a certified rebuild is commonly done well into five-figure hours, but the exact interval varies by configuration/series and duty cycle, so treat any quoted number as a guide, not a guarantee. Inspect wet brake oil for discoloration or a milky look that points to water contamination, and check articulation pin and bushing play by hand with the truck on level ground. Look at the retarder oil cooler core for dust packing, and confirm the payload measurement system is still reading and calibrated correctly, since a drifted payload readout is an easy thing for a seller to overlook. Given how much of this touches the braking and retarder system, have your dealer verify brake and cooling condition as part of any pre-purchase inspection.
