Caterpillar BP22

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar BP22 is a mid-size hydraulically driven pickup broom built as a mounted work tool rather than a standalone machine. It carries no engine and no chassis of its own; a single hydraulic motor spins the 700mm (27.6in) brush using flow and pressure supplied entirely by the host carrier. The broom sweeps a 2200mm (86.6in) path, weighs 580kg (1279lb), and rides on a floating suspension with no support wheels, letting it follow ground contour on its own. A 0.55m3 (0.7yd3) hopper and an optional integrated 400L (106gal) water spray tank suppress dust during sweeping. It sits in the middle of Cat's BP pickup-broom lineup, between the smaller BP18 (~1.8m) and the larger dual-motor BP25 (~2.5m), and mounts to Cat compact wheel loaders in the 906-908 range as well as skid steers, backhoe loaders, and integrated toolcarriers fitted with a compatible quick-coupler and 12V control circuit. Production records show a single confirmed serial prefix (8HZ), consistent with one continuous build run rather than distinct lettered generations.

Because the BP22 has no engine, transmission, or undercarriage, its design has stayed mechanically stable rather than going through the generational engine and emissions changes seen on powered Cat equipment. The parts that actually wear are the polypropylene brush-wafer sections, the hydraulic motor seals and spindle bearings, and the water-spray nozzles and hoses, all low-cost, easily sourced service items compared to an engine rebuild. Brush sections are also available in wire or 50/50 poly/wire mixes for harsher debris, extending the tool's usefulness beyond stock bristle wear. This simplicity, combined with strong compatibility across Cat's compact wheel loader and skid steer lines, keeps used BP22 units and their wear parts in steady demand from municipal street-sweeping departments, landscapers, and general contractors who need low-cost, low-maintenance sweeping capacity without dedicating a purpose-built sweeper truck to the job.

BP22 fluids & capacities

System	Capacity	Recommended fluid
Hydraulic drive motor (broom spins via single direct-drive hydraulic motor, no onboard gearbox)	No dedicated onboard reservoir; runs off carrier machine's hydraulic tank. Required flow 20-80 L/min (5-21 gal/min), optimal pressure 150-260 bar (2176-3771 psi) via 3rd-function circuit	Match carrier machine's own hydraulic fluid spec (typically Cat HYDO Advanced or equivalent anti-wear hydraulic oil); OMM defers to host machine's O&M manual for viscosity-by-climate grade, since the attachment has no separate fluid of its own
Dust-suppression water spray tank (optional kit, integrated onboard tank)	approx. 400 L (106 US gal) when water sprinkler kit is fitted; not present on units ordered without the kit	Clean water only, no lubricant additive specified; in freezing climates OMM guidance for other Cat water-tank options calls for draining or an approved non-corrosive antifreeze additive, but this is not independently confirmed for BP22 specifically
Brush-core spindle bearings and hydraulic-cylinder pivot/wear points (angle-adjust cylinder mounts, gutter-broom pivot)	No fill capacity; hand-applied at grease fittings per scheduled interval	Cat Multipurpose Grease (NLGI 2), Cat Advanced 3Moly Grease also listed in Cat's general work-tool lubricant guidance for cold-weather service; no BP22-specific viscosity-by-climate table located

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

Caterpillar BP22 maintenance schedule

Service interval	Tasks
Every 10 h	Inspect brush wafers for wear, cracking, or missing bristle sections before daily use. Check and clear debris from nozzle bars and hopper/deflector to keep discharge unobstructed. Grease the brush-spindle bearings and cylinder pivot points with Cat Multipurpose Grease NLGI 2. Inspect hydraulic hoses, quick-couplers, and fittings for leaks, chafing, or loose connections. Confirm the floating suspension moves freely and the broom follows ground contour without binding. Drain and refill the water spray tank with clean water only if equipped, checking for sediment.
Every 50 h	Check hydraulic motor case-drain line and fittings for seepage or discoloration. Inspect gutter brush (if fitted) for wear and mounting security. Verify 12V control wiring and connectors at the tilt/spin controls are secure and corrosion-free. Re-torque brush-wafer mounting hardware and replace any cracked or worn segments.
Every 250 h	Inspect the hydraulic motor shaft seal for leakage and wipe down the motor housing. Check spindle bearing play and lubricate per grease schedule with fresh Multipurpose Grease NLGI 2. Inspect mounting frame, quick-coupler plate, and pivot bushings for cracks or elongation. Flush and clean spray-nozzle strainers and tank filter screen. Verify hydraulic flow/pressure at the carrier's auxiliary circuit is within the 20-80 L/min (5-21 gpm) and 150-260 bar (2176-3771 psi) range.
Every 500 h	Replace worn brush-wafer sections once bristle length reaches the manufacturer wear limit. Inspect hydraulic motor coupling and drive spline for wear or play. Check all structural welds on the broom frame and hopper for cracking. Inspect and clean or replace hydraulic hose assemblies showing surface wear or bulging.
Every 1,000 h	Remove and inspect the hydraulic motor internally for spline, bearing, and seal wear; rebuild or replace as needed. Inspect and repack spindle bearings, replacing seals if grease purge is contaminated. Check pivot bushings and shafts on the floating-suspension linkage for wear and replace if play exceeds tolerance. Pressure-test the water spray system for leaks and nozzle spray-pattern consistency.
Every 2,000 h	Overhaul or exchange the hydraulic motor if performance loss or internal leakage is confirmed. Inspect the full mounting frame and quick-coupler interface for fatigue cracking under load. Replace all suspension pivot bushings and pins as a set. Re-certify hydraulic hose assemblies and replace any beyond service life regardless of visual condition.

Servicing the BP22 beyond the schedule

Predictive Maintenance & Fluid Analysis

The BP22 has no engine oil or coolant to sample, so predictive care centers on the hydraulic motor and carrier hydraulic fluid. Track carrier hydraulic fluid cleanliness and case-drain temperature at the motor, since the BP22 draws directly off the host circuit with no reservoir of its own. Watch for rising case-drain flow or falling brush rpm at rated 20-80 L/min (5-21 gpm) as early signs of motor wear before a seal failure or spline breakage takes it out of service.

Corrective & Common Repairs

Most BP22 downtime traces to worn or missing brush-wafer sections, clogged spray nozzles, or a leaking hydraulic motor shaft seal. Replace individual wafer segments rather than the full brush core once bristle length drops below effective sweep contact. Clear hopper and nozzle-bar blockages daily to prevent uneven sweep pattern. Chafed hoses and worn quick-coupler faces at the carrier interface are the next most common corrective items given the constant flexing of the floating-suspension mount.

Overhaul & Rebuild Points

Because the BP22 carries only one hydraulic motor and no drivetrain, overhaul work concentrates there and at the spindle bearings and mounting frame. Rebuild the motor when case-drain leakage or spline wear reduces brush speed off its 306rpm rating. Repack and reseal spindle bearings when grease purge shows contamination. Inspect the mounting frame, quick-coupler plate, and floating-suspension pivots for fatigue cracking at major service intervals, since this frame absorbs all sweeping shock loads.

Seasonal & Environment Servicing

Drain the 400L (106gal) water spray tank, hoses, and nozzle lines fully before freezing weather to prevent cracked lines and a split tank. Flush the system with clean water only, since sediment accelerates nozzle wear. In cold climates, switch spindle and pivot grease to Cat Advanced 3Moly Grease for better low-temperature flow. Store the broom off the ground with wafers unloaded between seasons to prevent bristle set and uneven wear on the polypropylene sections.

Code	Meaning	Likely cause	What to do
CID 1180 - FMI 05	Auxiliary Hydraulic Solenoid #1 - open circuit	Broken or disconnected wiring/connector between the carrier's auxiliary hydraulic solenoid valve and the work-tool circuit that drives the BP22's hydraulic motor	Inspect and reseat the auxiliary hydraulic harness connector at the valve and at the carrier's work-tool coupler; check for a broken or chafed wire
CID 1180 - FMI 06	Auxiliary Hydraulic Solenoid #1 - short circuit	Pinched, chafed, or water-intruded wiring shorting to ground in the carrier's auxiliary hydraulic circuit feeding the broom motor	Inspect harness routing near the work-tool mounting plate for damage; check solenoid coil resistance against carrier spec
CID 1181 - FMI 05	Auxiliary Hydraulic Solenoid #2 - open circuit	Open wiring on the carrier's second auxiliary solenoid, relevant where the carrier uses two solenoids for flow direction/proportional control to the broom motor	Check connector continuity at the valve body and at the work-tool electrical coupler
CID 1184 - FMI 04	Auxiliary Hydraulic Solenoids Supply - voltage below normal	Poor ground, corroded connector, or wiring fault reducing supply voltage to the aux hydraulic solenoid circuit that controls broom flow	Check carrier battery voltage and supply wiring, clean and reseat ground and supply connectors at the aux valve
CID 1189 - FMI 08	Auxiliary Hydraulics Lever - abnormal or erratic signal	Faulty or dirty auxiliary control lever/switch on the carrier used to activate broom rotation, or a damaged signal wire	Cycle the auxiliary control lever, check for a clean on/off signal at the carrier's ECM, clean or replace the switch/lever assembly

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

BP22 attachments & work tools

Carrier compatibility

Mounts to Cat skid steer loaders, backhoe loaders, integrated toolcarriers, and wheel loaders, matched to the carrier's own pin-on or quick-coupler interface (skid steer quick coupler, IT/wheel loader coupler, or Fusion coupler on backhoe loaders). Runs off the carrier's auxiliary (third-function) hydraulic circuit rather than a dedicated power unit.

Hydraulic requirement

Needs 20-80 L/min (5-21 gpm) of auxiliary flow at 150-260 bar (2176-3771 psi) working pressure, driving a single hydraulic motor direct-drive brush at up to roughly 306 rpm. Carriers below this flow range cannot reach rated brush speed.

Water spray kit

Carries an integrated 400 L (106 gal) water tank feeding an onboard spray system that wets the surface ahead of the brush to hold down airborne dust during sweeping. Standard-fit feature on the BP22, not a bolt-on add-on kit.

Bristle/configuration options

Ships with replaceable polypropylene brush sections as standard; sections can be swapped to all-wire or a 50/50 poly-and-wire mix for heavier debris or abrasive surface work. A separate gutter brush is available to extend the pickup path along curbs and edges.

Suspension/pickup design

Uses a floating suspension design instead of support wheels, letting the pickup head follow surface contour so bristles keep consistent contact from initial setup, feeding collected debris into an integrated hopper (about 0.7 cubic yards) for dumping rather than windrowing it to the side.

Family size lineup

BP22 is the mid-size unit in Cat's pickup-broom line: sweeping width around 2.2 m (86.6 in), between the smaller BP18 (about 1.8 m / 72 in) and BP15 (about 1.5 m / 60 in) and the larger BP25 (about 2.5 m / 98.4 in, dual hydraulic motor). BP25 adds a second drive motor for its wider head; BP22 uses a single motor.

BP22 serial number reference

The PIN plate is a riveted metal tag mounted on the broom frame near the mounting/coupler end of the attachment, visible from the side or top of the unit. Read the first 3 characters as the model/plant prefix (letters or letter+digit combination) and the digits following as the sequential unit number; a prefix of 8HZ followed by 00001 or higher identifies a BP22 Broom-Pickup.

Prefix	Identifies	Notes
8HZ	BP22 Broom-Pickup, base/only production run	Confirmed as the BP22's own machine serial prefix (8HZ00001-UP) in the combined BA22/BA25/BP22/BP25 Brooms parts and service documentation. Frame, AR-Pickup broom assembly, and spray/water-tank components under this prefix match BP22's own 2.2-m (2200 mm) sweeping width. No sub-range letter/plant split found; treat as a single run.

Frequently asked questions

What engine does the BP22 have?

The BP22 has no engine of its own. It is a hydraulically driven attachment powered by a single hydraulic motor that runs off the auxiliary hydraulic circuit of its host carrier machine (compact wheel loader, skid steer, backhoe loader, or toolcarrier).

What is the BP22's operating weight?

The BP22 weighs 580kg (1279lb) as a standalone attachment, before adding the optional 400L (106gal) water spray tank or gutter brush.

What replaced the BP22?

No confirmed successor model is documented. Available records show a single continuous production run (serial prefix 8HZ), and the BP22 continues to sit as the mid-size entry in Cat's current BP pickup-broom lineup between the BP18 and BP25.

What BP22 owners discuss

Is one hydraulic motor enough to drive the BP22, or does it bog down on heavier material?

The BP22 runs off a single hydraulic motor turning the wafer-type brush core, unlike the wider BP25 which splits the load across two motors. On loose dirt, gravel, and yard debris one motor keeps up fine as long as the carrier is delivering the broom's rated flow (roughly 20-80 L/min, 150-260 bar). Where owners notice bogging is on wet sand or packed material with the down-pressure set too aggressive - the fix is backing off the float/down-pressure setting rather than blaming the motor. If the brush stalls or spins weakly even at correct flow and pressure, that points to a worn motor or a restriction in the return line, not an inherent single-motor limitation.

What's the normal wear pattern on the brush wafers, and how do I know when to replace them?

The wafer brushes wear evenly across the outside diameter under normal use. The common complaint is uneven, angled wear on one edge of the wafers - that's almost always from running with too much downward pressure, which drags the bristles sideways instead of letting them contact the surface square. Owners who dial in a lighter float setting report much longer wafer life. As a rule of thumb, check wafer diameter before each shift and after every 10 hours: once the outside diameter has worn down to about half its original size, replace them. Running wafers past that point costs sweeping width and lets debris pass under the core instead of being picked up.

The water spray bar quits putting out water or sprays unevenly - what's going on?

This is the most common complaint on the integrated spray system. The nozzles are small and sit right in the dust path, so they load up with grit and mineral scale, especially if the tank gets filled from a dirty source or sits unused for a season. Uneven or weak spray from one or two nozzles is almost always a partially clogged tip, not a pump or plumbing failure. Pull the nozzles, soak them, and clear them with a soft brush or compressed air - avoid picking at them with a wire or blade, which enlarges the orifice and ruins the spray pattern. Fitting a simple inline strainer ahead of the spray bar and using clean fill water cuts clogging way down. If the whole bar has no pressure at all, check the tank vent and the on/off valve before assuming a pump problem.

I hooked the broom up and it won't spin, or only spins one direction - what should I check first?

Nine times out of ten this traces back to the hydraulic hookup, not the broom itself. Confirm both auxiliary couplers are fully seated - a half-connected flat-face coupler will let fluid trickle through without building real flow, which shows up as a weak or dead motor. Next, cycle the broom function a few times to purge trapped air from the lines; a spongy or one-direction-only motor often clears up once air works its way back to the tank. If it still won't turn evenly in both directions after that, check the case drain / return line for a kink or blockage - a restricted return will let the motor labor in one rotation and stall in the other. Persistent stalling after ruling out hookup and air issues usually means internal motor wear, and that's worth having your dealer verify before you swap parts.

Will a BP22 mount up to any skid steer, or do I need a specific plate?

The BP22 uses the same universal quick-attach mounting geometry shared across skid steers, compact track loaders, and integrated toolcarriers from most major brands, so cross-brand hookup is normal and widely reported as trouble-free. The wrinkle comes with compact wheel loaders - those need the loader-specific mounting plate/adapter rather than the skid steer plate, and buyers who skip that detail end up with a broom that won't pin on. Also confirm hydraulic coupler type before buying secondhand: Cat's flat-face couplers are common industry standard, but a broom that's been re-hosed with a different fitting style will need adapters or new ends to hook up cleanly on your carrier.

The hopper won't dump cleanly or debris backs up in the pickup area - is that a design flaw?

Not typically a design issue - it's almost always ground contact or debris packing. The hopper dumps by gravity as the carrier's arms raise and tilt forward, so if the bottom edge is dragging on uneven ground or the broom's float/leveling setting is off, material won't clear the hopper lip properly. Check that the suspension/float system is letting the broom ride level over the surface rather than digging in on one side. Heavy wet debris or long stringy material (roots, wire, plastic sheeting) is the other common cause of packing in the pickup area ahead of the hopper - clear it by hand rather than forcing the brush through it, which accelerates wafer wear.

What should I check on a used BP22 before buying it?

Start with the wafer brushes - measure remaining diameter and look for angled wear, which signals a prior owner ran heavy down-pressure. Check the motor mount and brush core for play, and confirm the motor spins evenly in both directions under load rather than just idling free. Inspect all hydraulic hoses, fittings, and the case drain line for cracking, weeping, or amateur repairs, and make sure the flat-face couplers seat and lock properly. Test the parking stands for stability and check the leveling/float mechanism moves freely instead of being seized with rust or packed debris. Run the water tank and spray bar if equipped - a dry, unused tank with clogged nozzles is common on units that sat outside. Any hydraulic leak at the motor seal or a broom that won't spin cleanly in both directions is worth having your dealer verify before you commit to the purchase.
