Caterpillar AP-1055B
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar AP-1055B is a highway-class, Mobil-Trac tracked asphalt paver built for base and surface-course work on wide roadways and lots. Cat rated it at a base operating weight of about 16,100 kg (35,501 lb) without screed, and power comes from a Cat 3116TA turbocharged, aftercooled inline-six diesel producing 130 kW (174 hp) gross, governed electronically through Cat's pre-ACERT PEEC system rather than the ACERT/HEUI setups that followed. Cat built the AP-1055B from roughly 1996/1997 through 2004, spanning the 8BM, ABB, and A3P serial-prefix ranges, as a running update to the earlier AP-1050B Mobil-Trac line and the direct predecessor to the C7 ACERT-powered AP-1055D. Standard screed choices were the 2.5 m AS2251 or 3.05 m AS2301, each with hydraulic bolt-on extensions out to a 9.1 m (30 ft) maximum paving width, plus a wider AS3251/AS3251C Extend-A-Mat screed option for larger jobs.
Across its production run the AP-1055B kept the same 3116TA/PEEC powertrain and Mobil-Trac undercarriage architecture; differences between the 8BM, ABB, and A3P serial ranges are mostly running production changes to the feeder/auger control electronics, track-tensioning accumulator hardware, and operator-station wiring rather than a driveline redesign. That mechanical simplicity is exactly why the model still matters in the used and parts market today: buyers looking to avoid ACERT-era emissions hardware and electronic diagnostics gravitate to the 3116TA's simpler mechanical unit-injector fuel system, and used AP-1055B units keep trading well past 8,000-10,000 hours as budget-tier pavers. Parts demand centers on the Mobil-Trac belts and tensioning components, auger/conveyor gearboxes, and screed wear items, since those consumables wear out well before the base engine or frame does.

Servicing the AP-1055B beyond the schedule
Predictive Maintenance & Fluid Analysis
Sample 3116TA engine oil at every 250-hour change and watch for fuel dilution, a known tell on this mechanical unit-injector engine as pump plungers and injector tips wear. Sample hydraulic oil and auger/conveyor gearbox oil on the 500- to 1000-hour service cycle for water and metal content, since the electronic-over-hydraulic auger and screed controls are sensitive to contamination. Log PEEC governor fault codes at each service, and track turbocharger shaft play and aftercooler fouling as early warning signs before a hot-side failure.
Corrective & Common Repairs
Expect Mobil-Trac belt cord fatigue and tensioning-accumulator leaks as the most common track-side repair, especially on machines left outdoors between seasons. Auger gearbox seals weep after repeated heat-soak/cool-down cycles against hot mix, and conveyor drag chains stretch and need slat replacement. Screed heater failures show up as cold spots across the plate width, whether the machine runs electric elements or a propane burner. PEEC sensor and wiring faults are the usual cause of erratic idle or power loss on the 3116TA.
Overhaul & Rebuild Points
High-hour AP-1055B units typically need auger and conveyor gearbox rebuilds, Mobil-Trac belt replacement once wear bars or steel cords show, and propel pump/motor overhaul as hydrostatic drive efficiency drops. On the 3116TA, plan turbocharger and injector reconditioning together at major overhaul, since both wear together under continuous paving load. Screed vibrator bearings, extension slide rails, and heating elements form a matched wear set worth rebuilding together rather than piecemeal.
Seasonal & Environment Servicing
Before first paving of the season, cycle the Mobil-Trac belts and check tensioning-accumulator pressure after winter storage, and confirm the PEEC-governed 3116TA cold-start aid works before relying on it in low temperatures. Test coolant freeze protection and verify every screed heating element reaches temperature before the first mat. At season end, strip asphalt buildup off augers, conveyor, and screed plates, drop hydraulic oil viscosity grade if the machine works into colder weather, and protect exposed cylinder rods from corrosion during layup.

AP-1055B fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Flash Code 55 | No active diagnostic faults logged since the last key-on cycle | Normal condition; not a fault | No action needed; if a symptom persists with no code, check mechanical/hydraulic systems directly since the governor reports electrical faults only |
| Flash Code 22 | Fuel rack (fuel control) position sensor fault on the electronic governor | Open or shorted rack position sensor circuit, or a signal changing faster than the rack can physically move | Inspect rack position sensor wiring and connector for damage/corrosion, then verify sensor output with Cat ET before replacing the sensor |
| CID 0100-FMI 01 | Engine oil pressure below normal for current engine speed | Low oil level, worn oil pump, plugged filter, or a failed oil pressure sensor/wiring fault | Check oil level and filter condition first, confirm with a mechanical gauge before condemning the sensor |
| CID 0110-FMI 00 | Engine coolant temperature above normal operating range | Low coolant level, restricted radiator/airflow, slipping or failed fan drive, or a faulty coolant temperature sensor | Check coolant level and radiator for debris, verify fan drive engagement, then confirm sensor reading against a manual temperature check |
| CID 0111-FMI 01 | Coolant level below normal | Low coolant in the sight glass/recovery bottle or a faulty coolant level switch | Top off coolant and inspect for external leaks, check level switch and wiring if the code returns with coolant full |
| CID 0190-FMI 08 | Engine speed/timing signal abnormal or erratic | Damaged speed/timing sensor, excessive sensor air gap, or a chafed harness near the engine timing gear cover | Check sensor gap and mounting, inspect harness for chafe points, then verify signal with Cat ET |
| CID 0091-FMI 02 | Throttle/speed control position signal erratic or intermittent | Worn or dirty throttle position sensor, loose linkage, or an intermittent connector | Inspect throttle linkage and connector, clean and reseat connections, recalibrate governor settings if the fault clears |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
AP-1055B attachments & work tools
Extending screeds (AS2251 / AS2301)
The AP-1055B pairs with Cat AS2251 (2.5 m / 8'2" standard width) or AS2301 (3.05 m / 10' standard width) hydraulically extending screeds. Front-mounted power extenders take the AS2251 out to 4.27-4.4 m (14'5") and the AS2301 out to 5.49 m (18') without tools.
Bolt-on screed extensions
Bolt-on extension sections in 305 mm (12") and 610 mm (24") widths mount on the extender frames for extra-wide paving, pushing the AS2251 up to about 6.1-6.2 m (20'5") and the AS2301 up to about 7.32 m (24'). These sections heat by convection from the main screed rather than their own burners.
Wide-format screed (AS3251 / AS3251C Extend-A-Mat)
For jobs needing frequent, large width changes, a wider Extend-A-Mat-style screed (AS3251/AS3251C family) is offered for this paver class, with tamper, vibratory, and alternate LPG or electric plate heating configurations in place of the standard diesel burners.
Cutoff shoe package
Bolt-on cutoff shoes narrow the paving width when working tight areas: 305 mm (12") or 610 mm (24") shoe sets adjustable in 76 mm (3") increments, bringing the AS2251 down to about 1.9 m (6'2") and the AS2301 down to about 2.44 m (8').
Screed compaction systems
Standard main-screed and extender vibrators run 0-50 Hz (about 0-3,000 vpm) for initial mat compaction. A tamper-bar screed variant is also offered for this class for higher pre-compaction density, though it runs at a slower maximum paving speed than the plain vibratory screed.
Screed plate heating
Standard heating uses diesel-fired burners (two on the main screed, one per extender) on a baffled, insulated combustion chamber with a built-in 15-minute timer to prevent plate overheat; glow-plug ignition is worked from the main screed control boxes. LPG or electric heating is available as an alternate configuration on the wider screed line for this paver class.
Power crown and power height controls
Manual hand-crank crown (about +10% to -3%) and extender height adjustment (in 6.4 mm / 0.25" increments) are standard; optional electric motor-driven gearboxes give fingertip power crown and power extender-height control from the screed console instead.
Thickness control screw configurations
Mat-thickness screws at each control console are offered in four thread configurations (clockwise standard, counterclockwise standard, clockwise Acme, counterclockwise Acme) to match operator preference or crew habit.
Screed mounting / coupling
The screed attaches to the tractor through leveling (tow) arms with a pull-point linkage rather than a quick-attach coupler; front-mounted hydraulic extenders ride on paired 51 mm (2") diameter tubes bolted to the main screed frame for torsional rigidity.
Feed and material-handling sensors
Auger and hopper feed can run on automatic proportional feed sensors (ultrasonic material-level sensing) tied to the screed control boxes, keeping head-of-material consistent across the width without constant operator adjustment.
Operator protection and guarding
An operator's station canopy/ROPS structure is offered for sun and weather protection; the conveyor tunnel and auger chamber use a ventilation/extraction arrangement to pull fumes away from the walkway area, and full-length screed walkways use open-faced, slip-resistant grating as standard guarding for screed-side crew.

AP-1055B serial number reference
The PIN plate on the AP-1055B is a riveted metal tag mounted on the main frame near the operator's platform/engine compartment; if it is unreadable, the PIN is also stamped into the frame steel itself. The prefix is the first 3 characters of the 8-character PIN (e.g. 8BM, ABB, A3P) and identifies the serial/build range; the remaining digits are the sequential unit number within that range. Clean the plate area and use a flashlight if the stamped digits are worn or painted over.
| Prefix | Identifies | Notes |
|---|---|---|
| 8BM | AP-1055B asphalt paver, early production run | Cat 3116 diesel engine (3116TA, approx. 174 hp / 130 kW). Earliest known AP-1055B production prefix; an example unit, 8BM00163, was built in 1997. Range believed to start around 1994. |
| ABB | AP-1055B asphalt paver, mid production run | Cat 3116 diesel engine. Mid-production prefix, starting from ABB00001-up. Range believed to open around 1999 and run into the early 2000s; an example unit, ABB0047, carries a 2002 build date, so treat any single model-year figure as approximate and confirm the exact year with your dealer. |
| A3P | AP-1055B asphalt paver, later production run | Cat 3116 diesel engine. Latest known AP-1055B production prefix; an example unit, A3P00205, was built in 2004. The successor AP-1055D moved to the C7 ACERT engine, so 3116-based service data stops at this prefix. |
Frequently asked questions
What engine powers the Caterpillar AP-1055B?
A Cat 3116TA turbocharged, aftercooled inline-six diesel rated at 130 kW (174 hp) gross, governed electronically through Cat's pre-ACERT PEEC system. It is not the later C7 ACERT engine used in the AP-1055D.
What is the operating weight of the AP-1055B?
Base operating weight without screed runs about 16,100 kg (35,501 lb). Actual working weight varies with the screed fitted (AS2251, AS2301, or the wider AS3251/AS3251C Extend-A-Mat) and any hydraulic extensions, so check the data plate for your exact configuration.
What replaced the Caterpillar AP-1055B?
The AP-1055D succeeded it, carrying over the Mobil-Trac tracked chassis but switching to the C7 ACERT diesel and updated electronics. The current Tier IV Final "AP1055" on the market today is a separate, much later machine and does not share the AP-1055B's engine or specs.
What AP-1055B owners discuss
How do mechanics tell a failing propel pump from a failing drive motor on the AP-1055B's Mobil-Trac drive?
By how the machine loses power. A weak hydrostatic pump usually drags both sides of the drive down together, so the paver just feels universally sluggish. A weak drive motor (or a sticking swashplate/control on one side) shows up as the machine pulling or crabbing toward the weak side, most noticeable under load or on a grade, and it tends to get worse once the oil is hot. Pull the hydraulic filters before condemning anything - fine metal in the filter media points to internal pump or motor wear already circulating through the system. Have your dealer verify hydrostatic circuit pressures before swapping components.
What quirks does the 3116TA in the AP-1055B have that owners run into?
The fuel system is known for being stubborn to bleed after any service - the secondary filter mounts filter-down so it can't be pre-filled, and it can take a lot of cranking to purge air after a filter change or line disconnect. A clogged fuel-supply check valve causes intermittent hard-start or rough-run complaints that get mistaken for electrical faults. Injector tip o-rings hardened by heat cycling are a common wear point; combustion gas leaking past them shows up first as a gradual power loss before a full injector failure. Mechanical rack-style units on this engine need factory-specific timing and rack-setting tooling - don't attempt without it. Fuel system configuration varies by build/serial range on this engine family, so confirm whether your specific unit runs mechanical rack injection or HEUI before ordering injector parts.
What wear pattern is typical on the AP-1055B's Mobil-Trac rubber-belt undercarriage?
Mobil-Trac keeps belt tension automatically through a hydraulic cylinder and accumulator, so there's no manual track adjustment to chase. Wear shows up first as the belt's internal steel-cable layers start telegraphing through cracks in the rubber cover, and as uneven wear at the bogie/roller path where the flotation rollers ride - if wear looks lopsided, check bogie oscillation hardware and roller bearings before blaming the belt. The belt itself is a wear consumable with no field-rebuildable core; once the cable layers show through, replacement is the only fix. Keeping the belt clear of embedded stone extends life noticeably compared to units that pave over rough millings.
What feeder-system wear should I expect to find on a hard-worked AP-1055B?
The auger and conveyor system takes the brunt of hot-mix abrasion. Common finds on used units: floor plates thinned and starting to warp, auger flights worn to a point and losing diameter (shows up in the field as streaking in the finished mat), conveyor chains sagging past their adjustment range, and auger bearing seals that failed and let mix contaminate the shaft and bearings. This wear is a better health indicator than the hour meter on a paver that ran a lot of stop-start city work versus steady highway mat, so check it closely regardless of what the meter reads.
What electrical or sensor problems come up most on this paver family?
Screed heating and grade-control sensors generate the bulk of electrical complaints. Screed heating element connectors corrode where moisture collects, especially after rain or a wash-down, and that corrosion produces uneven-heat or ground-fault symptoms well before any heating element itself is actually bad - cleaning and drying connectors resolves a large share of these before parts get condemned. On grade/slope retrofits using sonic sensors, any sensor not actively in use on a folded or averaging beam should be unplugged; an active sonic sensor picking up an idle sensor's pulse is a well-known cause of erratic grade readings. Have your dealer verify screed ground-fault wiring before working on energized heating circuits - shock and burn hazard.
Why does this paver leak gear oil into the flywheel housing, and is it a big repair?
It's a recurring complaint on the engine-to-hydraulic-pump drive train shared across this paver line: gear oil from the pump gearbox (typically an 85W-140 gear lube) seeps past the gearbox input shaft seal into the flywheel housing, which is designed to run dry. On higher-hour units that seal hardens and starts weeping; a plugged crankcase breather can add backpressure that accelerates the leak, so check the engine vent is clear before condemning the seal. The repair means separating the gearbox from the flywheel housing, which is tight working space on this platform - some shops pull the pumps and gearbox as an assembly, others pull the engine, it comes down to available lift and shop preference. Have your dealer verify before doing flywheel-housing work near the rotating drive coupling.
What should I check before buying a used AP-1055B?
Start with the feeder system: floor plate thickness, auger flight wear/diameter, conveyor chain sag, and auger bearing seals for mix contamination. Inspect the Mobil-Trac belt for cracking or exposed steel cable and check bogie/roller wear for evenness. Run the hydrostatic drive under load both directions and watch for crabbing or pulling to one side, and pull the hydraulic filters to check for metal contamination. On the engine, check for fuel-system hard-starting complaints and look at the flywheel housing drain/inspection area for gear-oil residue from the pump gearbox. Cycle the screed heat and check every heating zone reaches temperature evenly, and confirm grade/slope sensors calibrate and hold a reading without drift. With good maintenance these pavers can run a long service life, but component life depends heavily on how the machine was actually used - continuous highway mat wears very differently than stop-start city paving. Have your dealer verify hydraulic and drivetrain condition with a proper inspection before final sale.
