Caterpillar 10B
Maintenance schedule, common problems & OEM parts breakdown
The Cat Pavemaster 10B is a fixed-width paving screed, not a self-propelled paver. Base paving width is 3.05 m (10 ft); with bolt-on cutoff shoes and strike-off extensions the documented paving range runs 2.44 m to 9.14 m (8 ft to 30 ft) depending on the extension set fitted. It has no engine, powertrain, transmission, or hydraulic tank of its own — it bolts to a separate Cat paver tractor, most commonly the AP-1000B, and is documented within the same AP-1000B/AP-1050B/AP-1055 tractor family, drawing hydraulic power, fuel, and electrical signals from that tractor. Working systems are twin oil-fired burners with electric ignition for plate heating, a crown and slope adjustment mechanism, and a vibratory compaction system. Documented serial prefixes (3RM, 3MM, 3PM, and a less-verified BKB) place production from roughly the early-to-mid 1990s onward; an exact end date is not publicly documented. The 10B sits in the Pavemaster B-series alongside the narrower 8B, which shares the same conventional fixed-width design at a 2.44 m (8 ft) base width. It is a distinct product from the Extend-A-Mat 10-20B, which varies its paving width through a hydraulically extending mainboard instead of bolt-on extensions.
Across Pavemaster-generation screeds, heating moved toward twin insulated-combustion-chamber burners with electric ignition for more even plate temperature and less operator babysitting, and strike-off control moved toward optional on-the-go height and slope adjustment rather than manual crank-only setups. Caterpillar has since folded fixed-width and extending screed concepts into its current SE-series line (SE47, SE50, SE60), which is why no single named model is documented as a direct 10B replacement. The 10B still holds value in the used and parts market because it is mechanically simple: no electronics beyond basic burner ignition and lockout indicators, so a shop with basic fabrication and bearing skills can keep one running indefinitely. Because it bolts to a tractor rather than selling as a complete machine, used 10B screeds get mixed and matched with whatever compatible AP-series tractor a contractor already owns, which keeps steady demand alive for wear plates, extension slide components, burner parts, and vibratory bearings long after Caterpillar stopped actively marketing the model.

Caterpillar 10B specifications
Engine
| Model availability | Not applicable. The 10B is the Cat Pavemaster 10B paving screed, a bolt-on implement with no engine of its own. Engine data belongs to the carrier paver tractor (commonly the AP-1000B), not to the screed. |
Weights
| Operating weight | Not published separately from the carrier tractor. No source documents a screed-only operating weight for the 10B. |
Dimensions
| Base paving width | 3.05 m (10 ft) fixed base; 2.44-9.14 m (8-30 ft) with bolt-on cutoff shoes and strike-off extensions fitted, depending on the extension set used. |
Performance
| Travel speed | Not applicable — the screed has no propulsion of its own; travel speed is a function of the carrier paver tractor. |
Service capacities (summary)
| Fuel/fluid capacities | No independent fuel tank, hydraulic reservoir, or coolant system on the screed. Burner fuel and hydraulic oil are drawn from the carrier tractor's own systems; see the fluids section for grease-point specification. |
Values vary by configuration, region, and serial range — confirm against your machine before planning transport or lifts.
10B fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Machine type clarification | Not applicable — no capacity chart exists for this designation as a standalone paver | Cat 10B is the Pavemaster B Screed, Model 10B: a fixed-width 3.05 m (10 ft) conventional paving screed, extendable to 2.44-9.14 m (8-30 ft) with bolt-on extensions and cutoff shoes. It is a towed/mounted implement bolted to the tow arms of a Cat paver tractor (e.g. AP-650B, AP-900B, AP-1000B, AP-1050B), not a self-propelled paver. It has no engine, no cooling system, no transmission or powertrain, no final drives, and no axles/differentials of its own, so the operation and maintenance manual for this unit does not carry refill capacities for those systems. |
| Screed heater (oil-fired plate burners) | No dedicated onboard fuel tank documented for the screed burners; not a separately specified capacity in the screed's manual | Diesel fuel, drawn from the carrier paver's own fuel tank/system — same grade the paver's engine manual specifies. Two oil burners with electric ignition heat the screed plates; no distinct oil or coolant spec applies to the burner itself |
| Screed hydraulic functions (extension, crown, slope, leveling cylinders) | No separate hydraulic reservoir on the screed; capacity is governed by the carrier paver's hydraulic tank (varies by paver model — verify against that machine's own manual) | Same hydraulic oil as the carrier paver's hydraulic system (Cat HYDO Advanced or Cat TDTO-class fluid per the paver's manual), split by climate per that paver's viscosity chart (e.g. Cat HYDO Advanced 10 for general duty, arctic-grade equivalents for cold climates). The screed draws hydraulic power through hoses from the paver; it has no independent supply |
| Grease points (screed pivot pins, leveling arms, extension slides, bushings) | Not a reservoir — lubricated via grease fittings; no bulk capacity specified | Cat Prime Application Grease (multipurpose NLGI 2, moly-fortified EP lithium-complex), or equivalent NLGI Grade 2 EP multipurpose grease. No climate-split viscosity note applies to grease points on this unit |
Capacities are refill values from factory literature — always fill to the dipstick/sight gauge, not the number.

Servicing the 10B beyond the schedule
Predictive maintenance and fluid analysis
The 10B carries no independent fluid reservoir, so any oil analysis runs through the carrier tractor's hydraulic system, not the screed itself. Track vibratory eccentric shaft bearing condition by feel and sound at every grease interval, watching for heat, play, or gritty rotation before outright failure. Log burner flame color and carbon buildup rate over time as an early warning sign of nozzle or electrode wear. Watch tow-arm pin and bushing wear trends, since play here signals early fatigue in the main frame before cracking shows.
Corrective and common repairs
Most 10B faults trace back to the twin oil-fired burners: fouled nozzles, pitted electrodes, or a weak ignition transformer cause uneven plate heat and cold-mix drag marks behind the screed. Extension slide wear plates and strike-off edges wear fastest on abrasive mixes and need periodic shimming or replacement to hold crown accuracy. Crown/slope mechanism binding is usually dry or corroded pivot pins rather than the adjustment screw or gear itself. Screed-mounted hydraulic cylinders tend to leak at the rod seals after prolonged sun and heat exposure.
Overhaul and rebuild points
Rebuild work concentrates on the vibratory shaft and bearings, the crown pivot assembly, and the strike-off plates. A full vibratory overhaul means replacing eccentric weights, bearings, and seals as a matched set rather than piecemeal, since mismatched wear throws compaction uneven across the 3.05 m (10 ft) plate. Strike-off and end-gate plates get resurfaced or swapped once thickness control drifts outside tolerance. Extension tubes and slide rails need re-shimming or wear-strip replacement to restore factory clearance after heavy service hours.
Seasonal and environment servicing
Cold-weather paving leans hard on the twin burners, so verify ignition output and clean the combustion chambers before the season starts so plate heat comes up fast at low ambient temperatures. Moisture works into the vibratory housing and grease fittings during wet-weather storage or wash-down, so re-grease immediately after washing and before extended lay-up. Before winter storage, drain residual fuel oil from burner lines, cap fittings against dirt intrusion, and block the frame off the ground to protect the tow arm and extension slides from corrosion.
10B fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Burner lockout / reset light (red) | Flame-failure safety lockout on the screed heater's oil-burner primary control; fuel and ignition are cut after a failed light-off attempt | No flame detected within the trial-for-ignition period; fouled photocell or flame sensor, fouled electrodes, air in the fuel line, or no fuel at the burner | Check fuel supply and bleed the line, clean or replace electrodes and the flame sensor, then press the reset button once; do not cycle the reset repeatedly |
| No-flame / ignition failure shutdown | Burner motor and ignition energize but the control shuts the burner down because it never confirms flame | Worn or misaligned ignition electrodes, sooted combustion chamber, weak ignition transformer, or fuel nozzle blockage | Inspect and clean electrodes and nozzle, verify ignition transformer output, clean the combustion chamber, then retest a light-off cycle |
| High-limit / overheat trip | Screed plate temperature limit switch has opened and shut the burner down to protect the plate and wiring | Thermostat or limit switch out of calibration, restricted airflow around the heating element, or a stuck-closed burner valve overheating the plate | Let the screed cool, check the limit switch and thermostat setting against spec, and inspect for restricted combustion airflow before restarting |
| Burner motor overload trip (breaker open) | Circuit breaker or overload for the burner fan/fuel-oil pump motor has tripped, stopping burner operation | Seized or binding fan or oil pump motor, damaged wiring, or a shorted motor winding | Reset the breaker once, check motor amp draw against spec, and inspect wiring and the motor for binding or shorts before repeated resets |
| Low fuel-oil supply / filter restriction indication | Burner will not sustain a flame or cycles on and off because of insufficient fuel delivery | Low fuel level in the screed's oil tank, a clogged fuel filter, or a failing fuel pump | Check tank level, replace the fuel filter, and verify pump pressure and flow against spec |
| Igniter/electrode fault (repeated lockout) | Burner locks out repeatedly on start-up attempts even after a reset | Cracked electrode insulator, incorrect electrode gap, or carbon buildup shorting the spark path | Clean or replace electrodes, set the gap to spec, and inspect the insulator for cracks before returning the burner to service |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
10B attachments & work tools
Model identification
The 10B is the Cat Pavemaster 10B, a fixed-width paving screed, not a standalone paver. It bolts to a separate Cat paver tractor, most commonly the AP-1000B and related AP-1050B/AP-1055 family tractors. It is a distinct product from the hydraulically extending Extend-A-Mat 10-20B screed line.
Screed width & bolt-on extensions
Base paving width is 3.05 m (10 ft). Bolt-on cutoff shoes and strike-off extensions widen the documented paving range to 2.44-9.14 m (8-30 ft) depending on which extension set is fitted; exact limits vary by configuration. Extensions ride on slide tracks and wear plates rather than a hydraulically telescoping mainboard.
Screed heating
Screed plates heat via twin oil-fired burners with electric ignition, or via an electric plate-heating system depending on how the unit was ordered. A properly working system reaches paving temperature well within 30 minutes under normal ambient conditions.
Compaction (vibrator/tamper) system
A hydraulically driven vibratory system on the screed runs off the carrier tractor's hydraulics, working with a curved nose-bar plate design to assist material flow ahead of the plates and precompact the mat.
Crown, slope & grade control
Manual crown adjustment is standard. Power crown, slope, and screed-height adjustment from the platform are available as options, drawing hydraulic power from the tractor; the tractor also supports automated grade-and-slope control packages (averaging beam or sonic sensor style) with brackets at the tractor and screed arms.
Auger & hopper feed (carrier tractor)
The carrier tractor's reversible auger and chain conveyor move mix from the hopper to the screed. Bolt-on auger extensions and hopper wing extensions are used to match wider screed setups, and optional hopper-level and mix-temperature sensors are documented for this paver class.
End gates
Adjustable, crank-operated end gates fit the outer edge of the screed to shape the mat edge and can be swapped for fixed gates depending on the job.
Mounting / base-machine compatibility
This screed is not a universal quick-coupler attachment. It is a tractor-matched unit that bolts and pins to the leveling (tow) arms of a specific paver tractor, most commonly the Cat AP-1000B; exact tractor/screed pairing varies by build year and should be confirmed by serial number with a dealer.
Hydraulic power source
Vibration, power crown/slope controls, and screed cylinders all draw off the carrier tractor's hydraulic system; the screed has no independent reservoir. Factory-order options recorded alongside this screed include an onboard hydraulic generator (to run electric screed heat) and front-wheel-assist traction drive on the tractor.
Carrier tractor reference
The AP-1000B tractor most commonly paired with this screed uses a Cat 3116TA turbocharged diesel rated at roughly 130 kW (174 hp). The screed itself has no engine and runs entirely on hydraulic power supplied by the tractor.
Guarding
Standard factory guarding covers the heated screed plates and burner/heating elements against incidental contact, along with walkway and hopper-area guarding typical of this paver class. No model-specific aftermarket guarding kits are documented in dealer literature.

10B serial number reference
The PIN/serial plate for the 10B screed is its own attachment plate mounted on the screed, separate from the paver tractor's PIN plate on the tractor body. Read the first three characters as the prefix - Cat's parts system uses that prefix to pin down the correct production block and fitment - and give it to the parts counter along with the trailing serial digits before ordering. If the plate is hard to find or worn, the paver tractor's operation and maintenance manual for that family usually shows the exact mounting point.
| Prefix | Identifies | Notes |
|---|---|---|
| 3RM | 10B Pavemaster fixed (crownable, non-extending) screed, 3.05 m (10 ft) base width - the 10-ft sibling of the 8B Pavemaster screed | Dated to around 1993 in period parts-catalog records. Carries no engine of its own - it is a bolt-on screed towed by and hydraulically powered from a paver tractor, with burner or electric heat for the plates. Covered together with the 8B in a combined 8B/10B Pavemaster operation and maintenance manual, and individually in 10B-specific parts-catalog attachment listings. |
| 3MM | 10B Pavemaster fixed (crownable, non-extending) screed, 3.05 m (10 ft) base width | Dated to around 1996 in period parts-catalog records. No engine of its own - powered and heated from the paver tractor it mounts to. Appears both in the combined 8B/10B operation and maintenance manual and in standalone 10B parts-catalog attachment listings, including screed-extension components tagged specifically to the 10 ft screed for this range. |
| 3PM | 10B Pavemaster fixed (crownable, non-extending) screed, 3.05 m (10 ft) base width | Documented in a dedicated 10B parts catalog manual (3PM and up) as well as the combined 8B/10B operation and maintenance manual. No independent engine - runs off the paver tractor's hydraulics and electrics. |
| BKB | 10B asphalt screed, later production run using Cat's later three-letter-only prefix format (no digit lead-in like the 3xM prefixes) | Tied to the 10B across multiple parts-catalog attachment listings (screed frame wiring group and crown power-adjuster group each tagged to the 10B Asphalt/Pavemaster Screed). Exact build-year window not documented in sources checked - confirm with dealer. No engine of its own; power and heat come from the paver tractor. |
Frequently asked questions
What tractor does the 10B screed mount to?
The 10B is a bolt-on attachment, not a standalone machine. It mounts to a separate Cat paver tractor, most commonly the AP-1000B, and is documented within the same AP-1000B/AP-1050B/AP-1055 tractor family. Exact tractor-to-screed pairing varies by tractor generation and screed serial prefix, so confirm fit against the paver's own spec sheet or with a dealer before combining units.
What is the paving width of the 10B screed?
Base fixed width is 3.05 m (10 ft). With bolt-on cutoff shoes and strike-off extensions fitted, the documented paving range extends from 2.44 m to 9.14 m (8 ft to 30 ft), depending on which extension set is installed. No screed-only operating weight is published separately from the carrier tractor in available documentation — treat any such figure with caution and confirm with a dealer if it matters for transport or load planning.
What replaced the 10B in Caterpillar's screed lineup?
No single model is documented by name as a direct one-for-one replacement. The fixed-width Pavemaster and hydraulically extending Extend-A-Mat B-series screeds were succeeded generationally by Caterpillar's current SE-series vibratory screeds (SE47, SE50, SE60), which combine fixed and variable-width paving into one product line. Treat this as generational succession rather than a documented like-for-like swap, and verify current cross-reference with a Cat dealer.
