Caterpillar BA25
Maintenance schedule, common problems & OEM parts breakdown
The Cat BA25 is a hydraulically driven angle broom, a passive work tool attachment rather than a self-powered machine — it carries no engine, ECM, or onboard fluid reservoir. A direct-drive hydraulic motor (about 195 cm³/rev, 380-385 rpm at maximum flow) spins the brush off the carrier's auxiliary hydraulic circuit, rated for roughly 40-150 L/min (11-40 gpm) at 150-260 bar (2,176-3,771 psi, a narrower band on 12V variants). The head runs about 2700 mm (106 in) overall width with a 700 mm (27.6 in) brush diameter, sweeping 2500 mm (98.4 in) straight or roughly 2200 mm (86.6 in) angled up to 30 degrees either side, and weighs 430-600 kg (948-1,323 lb) depending on configuration. Cat offers it as Manual angle (pin-set), Hydraulic 12V, and Hydraulic 24V (electro-hydraulic angling), each available with an optional water sprinkler kit of roughly 167 L (44 gal) for dust suppression. A floating suspension holds constant ground contact without support wheels, and the unit includes parking stands and a leveling indicator. It mounts via Cat's quick-coupler tool interface to skid steer loaders, compact track loaders, backhoe loaders, and compact/small wheel loaders, sitting alongside the narrower BA18/BA22 and the wider BA30 in Cat's angle-broom line. No documented predecessor or successor ties directly to the BA25 name, and no public source gives a specific launch year — it remains part of Cat's current work tool catalog.
With no engine or electronics to split into generations, what varies across BA25 units is configuration, not model year: manual versus 12V/24V powered angling, dry versus water-kit equipped, and bristle wafer fill of poly, wire, or the standard 50/50 mix swapped to suit surface and season. Confirmed serial prefix 7AW1-Up covers current production; no distinct earlier or later series has surfaced in factory documentation. In the used and parts market the BA25 matters because it is a high-cycle wear item on municipal, rental, and site-cleanup fleets, and its value turns on mechanical condition rather than emissions or electronics history: bristle wafer wear, play in the hex drive coupling between the motor and brush core (the model's best-documented failure point), pivot bushing slop, quick-attach wedge wear, and hydraulic motor seal condition. Because it bolts to a wide span of carrier brands and sizes through a common coupler, a sound used BA25 stays useful well past the service life of the machine it originally shipped with.

Servicing the BA25 beyond the schedule
Predictive Maintenance & Fluid Analysis
The BA25 holds no oil of its own, so predictive care means watching the carrier's aux circuit and the broom's own wear signs. Sample the carrier's hydraulic oil on its normal schedule; metal fines flag wear inside the broom's direct-drive motor before a seal weeps. Confirm the carrier's rated flow sits inside 40-150 L/min at 150-260 bar before mounting up — this motor has no built-in bypass, so wrong flow overheats it fast. Check the hex drive coupling for play by hand monthly.
Corrective & Common Repairs
The single most common BA25 failure is the motor's hex drive stub rounding out in its socket on the brush core, usually from the drum jamming on frozen or wedged debris while the motor keeps turning against it. The fix is replacing the coupling, not just the motor. Other regulars: worn poly or wire bristle wafers, weeping motor shaft seals, a rocking quick-attach wedge or lock pin, and seized manual angle-adjust pins. Confirm any drive-socket repair with your dealer before returning the unit to service.
Overhaul & Rebuild Points
Past 2000 hours, rebuild the hydraulic motor as a unit — gerotor set, bearings, shaft seal, and the hex drive stub together, since a worn stub is the drivetrain's known weak point. Replace all floating-suspension pivot bushings and pins as a set rather than one at a time, since mixed wear reintroduces play fast. Inspect the brush core's mating socket for elongation, not just the motor's stub. Check the parking stands and leveling indicator for bent or seized components, and replace bristle cores once the tilt range is used up.
Seasonal & Environment Servicing
Flush the water sprinkler kit's lines and nozzles after every use and drain them fully before freezing weather; clogged nozzles and cracked hoses from trapped ice are the kit's main complaints. Run all-wire bristle wafers for icy or packed-dirt clearing and switch back to poly for routine pavement to control wear. In frozen or debris-jammed conditions, stop sweeping the instant the drum binds rather than letting the motor keep driving — that is what rounds out the hex drive coupling. Wash brine and grit off pivots weekly.

BA25 attachments & work tools
Machine identity and class
BA25 is itself a work tool, not a host machine: a hydraulic angle broom sized for skid steer loaders, compact track loaders, backhoe loaders, compact wheel loaders and small wheel loaders. It sits in the Cat angle-broom family alongside BA118, BA121, BA22 and BA30, spanning small to mid-size carriers.
Broom head and bristle options
Standard bristle fill is a 50/50 mix of replaceable polypropylene and steel wire segments. Segments can be reconfigured to all-poly (light sweeping, dust) or all-wire (heavy debris, ice/packed dirt) for the application.
Core dimensions (straight position)
Overall width about 2700 mm (106 in), sweeping width about 2500 mm (98.4 in), brush diameter about 700 mm (27.6 in), height about 1300 mm (51.2 in). Length figures vary by configuration (manual vs. hydraulic-angle, with or without water kit).
Angled sweeping geometry
Broom head angles left or right up to 30 degrees off straight, either by manual pin adjustment or, on the powered-angle version, hydraulically from the cab. In the angled position sweeping width narrows to roughly 2160-2200 mm (85-87 in) and overall width to roughly 2400-2430 mm (94.5-95.8 in), figures vary slightly by source/configuration.
Angling drive options
Offered as a manual angle broom (angle set by hand, brush rotation still hydraulically driven) or as a hydraulic angle broom where both brush rotation and left/right angling are hydraulically powered from the carrier's auxiliary circuit.
Hydraulic requirements
Runs on the carrier's standard-flow auxiliary hydraulics, direct-drive motor of about 195 cm3/rev (11.9 in3/rev). Optimal flow range about 40-150 L/min (11-40 gpm); optimal pressure quoted in the 150-260 bar (2,176-3,771 psi) range, with some listings showing a narrower 150-205 bar band, so treat the upper pressure figure as varying by configuration. Brush speed reaches roughly 380-385 rpm at maximum flow.
Electrical control options
Hydraulic-angle versions are offered in 12V or 24V electrical control variants to match the carrier's onboard electrical system, used to control the in-cab angling function.
Water/dust-suppression kit
An optional water sprinkler kit mounts to the broom to wet down material and cut airborne dust; tank capacity on kitted units runs around 167 L (44 gal). This option adds notably to installed weight and length versus the dry configuration.
Mounting and coupler interface
Attaches via Cat's tool-carrier quick-coupler interface, matched to the carrier class — skid steer/compact track loader quick-attach face, or the mounting group used on backhoe loaders and compact/small wheel loaders. No separate hydraulic coupler kit beyond standard auxiliary quick-connects is documented for this tool.
Suspension and support features
Uses a floating suspension design that keeps the brush at constant ground pressure through its vertical range of motion without needing support wheels. Units include parking stands for tool-off storage and a leveling indicator to help set brush angle/height.
Weight range by configuration
Installed weight varies with configuration: base manual angle broom is roughly 430 kg (948 lb), hydraulic-angle dry units run close to 440 kg (970 lb), and hydraulic-angle units with the water kit run up to roughly 600 kg (1,323 lb) once the tank and plumbing are added.
Typical applications
Marketed for clearing parking lots, industrial yards and mill yards, airport ramps/runways, streets, driveways and lanes — general-purpose surface sweeping rather than a specialized pickup/collection broom.

BA25 serial number reference
The PIN tag on a BA25 broom is a riveted or stamped metal plate on the main frame or mounting bracket, usually near the hydraulic motor or pivot casting rather than on the bristle section. Read the first 3 characters as the prefix (identifies the model/production series), and the digits that follow as the sequential unit number within that series.
| Prefix | Identifies | Notes |
|---|---|---|
| 7AW | BA25 angling/angle broom, hydraulic or manual angle drive | Serial range 7AW00001-Up. Named directly on a BA22, BA25 and BA30 angling broom parts catalog and matches real BA25 unit serials on the used-equipment market. Passive attachment powered off the host machine, no engine of its own. |
Frequently asked questions
What engine does the Cat BA25 angle broom use?
None. The BA25 is a passive hydraulic attachment with no onboard engine or ECM. Its brush is spun by a direct-drive hydraulic motor (about 195 cm³/rev) powered entirely by the host carrier's auxiliary hydraulic circuit, rated for 40-150 L/min (11-40 gpm) at 150-260 bar (2,176-3,771 psi).
What is the operating weight of the Cat BA25?
Operating weight runs from 430 kg (948 lb) for the Manual version up to about 600 kg (1,323 lb) for the Hydraulic 12V version with the water sprinkler kit fitted; the dry Hydraulic 24V and 12V versions fall in between at roughly 440-460 kg (970-1,014 lb).
What replaced the Cat BA25?
Nothing confirmed. No documented successor model exists; the BA25 remains part of Cat's current angle broom lineup alongside the BA18, BA22, and BA30. Verify current availability and configuration options with your dealer if a listing appears discontinued.
