Caterpillar CB-22
Maintenance schedule, common problems & OEM parts breakdown
The Cat CB22 and its CB22B follow-on form Caterpillar's smallest tandem vibratory asphalt roller class, built for utility paving, trench and shoulder work, and support rolling behind larger machines. The original CB22 (roughly 2007-2014) and the CB22B (roughly 2013-2019) both ride on a Cat C1.5 three-cylinder diesel, rated 33 hp (24.6 kW) on the CB22 and 36.2 hp (27 kW) on the CB22B. Operating weight lands around 2,553 kg (5,629 lb) on the CB22B, though the figure varies by configuration -- canopy versus open station and water tank load both shift it. Both drums measure 1,000 mm (39 in) wide, with a 64.3 L (17 gal) fuel tank and a 235 L (62 gal) water spray tank feeding the dust-suppression system, and top travel speed runs about 12 km/h (7.5 mph). Caterpillar built the line on an articulated, oscillating frame with a folding ROPS canopy, and retired the CB22B in favor of the CB2.5 and CB2.5 GC utility compactors launched in April 2021.
The step from CB22 to CB22B centered on the engine and service life: Caterpillar tuned the C1.5 for more power, 33 up to 36.2 hp, and stretched the factory oil change interval from every 250 hours to every 500 hours, cutting downtime on a machine that customers run hard on short, repetitive jobs. The B-series also added a simple onboard display for engine speed, fuel level, hour meter, and coolant/hydraulic temperature. In the used and parts market, the CB22/CB22B stays relevant as a low-hour, mechanically simple utility roller: drum, bearing, and water-spray wear parts carry over closely across the wider CB-series family, and a large installed base in trench and shoulder-work fleets keeps parts and service knowledge easy to find even though current Cat production has moved to the CB2.5 line.

CB-22 fluids & capacities
| System | Capacity | Recommended fluid |
|---|---|---|
| Engine crankcase (with filter) - Cat C1.5 diesel | 6 L (1.6 US gal) | Cat DEO (Diesel Engine Oil). SAE 15W-40 for moderate to warm climates, SAE 10W-30 for cooler ranges, Cat DEO-ULS Cold Weather SAE 0W-40 for sustained sub-freezing starts. Cat DEO-ULS/DEO-ULS SYN are also acceptable where low-sulfur fuel is used. Capacity reflects the C1.5-powered CB-series compactor platform; confirm exact figure for this serial range with a dealer before a first fill. |
| Cooling system | 6 L (1.6 US gal) | Cat ELC (Extended Life Coolant) preferred; Cat DEAC (Diesel Engine Antifreeze/Coolant) acceptable. Never run water alone. Verify exact figure for this serial range with a dealer. |
| Fuel tank | 64 L (17 US gal) | Ultra low sulfur No. 2-D diesel meeting Cat distillate fuel specification or ASTM D975/EN 590. Biodiesel blends up to B5 (B7 in some regions) are acceptable per the fuel standard in use. |
| Hydraulic system and tank | 26.6 L (7.0 US gal) hydraulic tank | Cat HYDO Advanced 10 (SAE 10W) preferred for the hydrostatic drive and vibratory circuit; Cat TDTO is an acceptable second choice. Use a lighter grade in cold-start climates and a heavier grade (Cat HYDO Advanced 30, SAE 30) in sustained hot-climate operation. |
| Vibratory drum eccentric weight housing (each drum) | 2 L (0.53 US gal) per drum | Cat GO (Gear Oil) SAE 80W-90, or an EP gear oil of equivalent grade. Change per the maintenance interval schedule; this housing is isolated from the main hydraulic system. |
| Water tank (drum wetting/spray system) | 235 L (62 US gal) | Clean water; add a non-freezing spray additive in below-freezing conditions to prevent line and nozzle damage. Not a lubricated system. |
| Grease (spec only) | Per external lubrication points; no reservoir capacity | Cat Advanced 3Moly or Cat Multipurpose Grease, NLGI Grade 2 for general pivot and bearing points. Cat Ultra 5Moly (NLGI 0/1/2 by climate) where extreme cold service is expected. Lubricate at the daily/periodic interval called out in the machine's service schedule. |

Servicing the CB-22 beyond the schedule
Predictive Maintenance & Fluid Analysis
Run oil and coolant samples on the C1.5 at every scheduled service instead of waiting for a fault code -- this is a mechanically simple three-cylinder platform, so fluid analysis is your best early-warning system. Track engine oil condition against the 500-hour change interval, and watch eccentric housing oil and hydraulic oil trends toward the 3,000-hour/3-year change. Rising hydraulic particulate counts often show up before propel motor or vibratory drive wear becomes audible on the drum.
Corrective & Common Repairs
Most CB22/CB22B repair calls trace back to the water spray system (clogged nozzle screens, fill strainer neglect), drum scraper wear, and articulation joint pins going dry between greasings. On the C1.5, some engines in this range are subject to a factory service letter covering an oil pump idler gear dowel fault that can cause a loss of oil pressure -- have your dealer verify this has been addressed before returning a used unit to work. Treat any oil pressure warning as a stop-and-inspect event, not a restart-and-monitor one.
Overhaul & Rebuild Points
Rebuild decisions on this class center on the drum bearings, eccentric weight shaft, and propel/vibratory hydraulic pumps rather than the engine, which is small and inexpensive to refresh. Inspect eccentric shaft bearings at the 3,000-hour/3-year mark for play or noise before they take out the housing. Check articulation joint bushings, drum shell thickness, and isolation mounts for cracking at major teardown; on a roller this size, chassis and drum wear usually outlast the engine's economical rebuild life.
Seasonal & Environment Servicing
Before winter storage, drain the water spray tank, lines, and nozzles completely -- a frozen spray system on the CB22/CB22B cracks pump housings and lines fast on a tank this size, 235 L (62 gal). Add fuel conditioner if the C1.5 sits idle, and top off coolant to the correct concentration for the expected low temperature. In hot, dusty paving environments, shorten the radiator and air filter cleaning interval below the standard 250-hour check, since the small engine bay traps asphalt dust quickly.

CB-22 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 1485-14 | Engine speed (RPM) increase/decrease command not being executed by the speed control circuit | Faulty RPM increase/decrease switch, damaged wiring or a loose connector at the engine speed control module, or a failed control module | Check the RPM switch for continuity and inspect wiring/connectors to the speed control module before replacing the switch or module |
| 100-1 | Engine oil pressure reading below the normal operating range | Low engine oil level, a clogged oil filter, worn oil pump, or a faulty oil pressure sensor | Check oil level and top off with the specified oil, inspect the filter, then test the oil pressure sensor and wiring if level and filter are normal |
| 110-0 | Engine coolant temperature above the normal operating range (overheat) | Low coolant level, a blocked radiator core, a slipping or failed fan drive, or a faulty coolant temperature sensor | Check coolant level with the engine cool, inspect the radiator for debris and airflow blockage, confirm fan operation, then test the coolant temperature sensor |
| 111-1 | Engine coolant level below the normal operating range | An external coolant leak or a faulty coolant level sensor/float switch | Inspect hoses, radiator cap and connections for leaks, top off coolant to the specified mixture, then verify the coolant level sensor |
| 168-4 | Battery/system voltage reading below the normal operating range | A weak or discharged battery, loose or corroded battery terminals, or a failing alternator/charging circuit | Clean and tighten battery terminals, load-test the battery, then verify alternator output at idle and at rated speed |
| 168-3 | Battery/system voltage reading above the normal operating range | A faulty alternator voltage regulator or a wiring fault causing overcharging | Test alternator output voltage at idle and at operating rpm and replace the alternator/regulator if output exceeds specification |
| 107-16 | Air intake filter restriction (differential pressure) above the normal range | A clogged or collapsed air filter element or a blocked intake path | Inspect and replace the primary air filter element and clear any intake obstruction |
| 3719-16 | Diesel particulate filter soot load approaching the level where regeneration is required | Extended low-load or low-temperature operation that prevents normal passive or active regeneration | Allow the engine to complete a stationary/parked regeneration per the operator manual and avoid prolonged idling at light load |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
CB-22 attachments & work tools
Drum / compaction package
Twin smooth steel drums, 1000 mm (39 in) wide, 700 mm (27.6 in) diameter, give a static linear load near 12.5 kg/cm (70 lb/in). Vibratory frequency is dual-selectable at 63 Hz (3,780 vpm) and 55 Hz (3,300 vpm) on the base CB22, widening to a 63/52/43 Hz spread on the CB22B series. Nominal amplitude runs about 0.5 mm (0.02 in) with centrifugal force per drum roughly 21-27.6 kN (4,725-6,210 lb); exact figures vary by configuration/series.
Traction control kit
Pin-on traction control option fits to the drum ends for extra grip in soft, wet, or loose underfoot conditions. It is designed as a field retrofit that installs in about an hour with no hydraulic modification needed.
ROPS and canopy configurations
Roll-over protective structure is offered foldable, fitted with gas shocks so one operator can fold it forward or back without tools, or fixed on the CB22B series. A sun canopy option mounts to either the fixed or foldable ROPS frame.
Water spray system
Standard 150 L (39.6 gal) polyethylene tank is built into the frame and gives about 1.5 hours between refills; an auxiliary 90 L (23.7 gal) tank option raises total capacity to roughly 240 L (63.4 gal). CB22B literature lists a single tank near 235 L (62 gal), so capacity varies by configuration/series. Intermittent spray mode roughly doubles run time between fills, and spray-bar shield guards are an available option.
Drum scraper system
Spring-loaded, self-adjusting scrapers ride at the front and rear of each drum as standard equipment, keeping the shell clean and spreading spray water evenly. Hinges retract during roading to cut wear when the scrapers are not needed.
Curb/edge drum offset
CB22B adds a 50 mm (2 in) drum offset to each side of the frame for closer work along curbs, walls, and obstacles without extra passes. This offset feature is not documented for the base CB22.
Lighting, guarding, and signal options
Factory option list covers a working light package, a roading light package, protective grids over the lamps, a rotating beacon, back-up alarm, spark-arrestor muffler, and an exhaust deflector.
Operator seat and control options
Seat choices range from non-suspension to a suspension or sliding seat, including a version with an operator-presence switch, plus a dual propel-lever control layout. Cocoa floor mats and a heat-retention device are offered as operator-station comfort options.
Vibratory control options
Beyond the standard front/rear/both-drum vibratory selector switch, options include rear-drum-only vibratory control and a delayed vibratory-on function that engages compaction only once the machine is already moving.
Telematics option
Product Link remote monitoring is offered as a factory or dealer-fitted option on the CB22B series for tracking hours, location, and basic machine health data.
Fluid and electrical options
An anti-freeze system, a bio-hydraulic oil fill, and a battery disconnect switch are offered as factory options. Ballast weight is available on the CB22B line to adjust operating weight for the job at hand.
Drum edge finish
Standard drums ship with machined edges; a non-machined drum edge option is offered as a lower-cost alternative where precise edge finish is not required.

CB-22 serial number reference
The PIN/serial plate on the CB22B utility compactor is a riveted metal tag on the machine frame. Cat machines in this class typically carry the plate on the outer frame, often near the articulation area, though exact placement should be confirmed on the physical machine. Check both the machine frame plate and the C1.5 engine's own serial tag separately, since the engine carries its own serial number distinct from the machine PIN. Read the first three characters as the serial prefix (identifies the production block) and the digits that follow as the running sequence number within that block.
| Prefix | Identifies | Notes |
|---|---|---|
| 419 | CB22B utility compactor, early production block | Serial range 4191-up. Fitted with the Cat C1.5 diesel. Meets EPA Tier 4 Interim / EU Stage IIIA emissions. Exact model-year boundary not published - confirm with a Cat dealer using the full PIN. |
| 2B2 | CB22B utility compactor, separate production block | Serial range 2B21-up. Same C1.5 diesel and Tier 4 Interim / Stage IIIA emissions coverage as the 419 group. Exact chronological order relative to the 419 block is not confirmed in available sources - confirm production date with a Cat dealer. |
| 466 | CB22B utility compactor, later production block | Serial range 4661-up, bounded to roughly 4661-131 before the LR2 block takes over. C1.5 diesel, Tier 4 Interim / Stage IIIA emissions. |
| LR2 | CB22B utility compactor, final production block before model replacement | Serial range LR21-up. C1.5 diesel, Tier 4 Interim / Stage IIIA emissions. CB22B was replaced by the CB2.5 / CB2.5 GC utility compactor line when Caterpillar launched its next-generation utility compactor lineup; LR2 covers the last CB22B builds before that changeover. |
Frequently asked questions
What engine does the Cat CB-22 use?
Both the CB22 and CB22B run a Cat C1.5 three-cylinder diesel. The original CB22 is rated 33 hp (24.6 kW); the updated CB22B is rated 36.2 hp (27 kW).
What is the operating weight of the Cat CB-22?
Operating weight runs around 2,553 kg (5,629 lb) on the CB22B. Exact figures vary by configuration -- canopy versus open station and water tank fill level both shift the number.
What replaced the Cat CB-22?
Caterpillar replaced the CB22B with the CB2.5 and CB2.5 GC utility compactors, launched in April 2021.
What CB-22 owners discuss
What is the most talked-about engine issue on the CB22 and its C1.5 diesel?
The recurring topic is a factory-known loss of engine oil pressure traced to the oil pump idler gear dowel on the C1.5 engine fitted to CB22 compactors. Reported symptom is a dropping or intermittent oil pressure reading rather than a sudden shutdown, and running the machine through that condition can spin bearings or force a full engine replacement. Cat covered affected units under an after-failure repair program that has since closed, so a machine still working today is outside that coverage window and any repair is on the owner's dime. Because the failure mode risks catastrophic engine damage, have your dealer verify oil pump and idler gear dowel condition, plus current oil pressure readings, before returning a suspect machine to service.
Why does compaction quality drop off even when the drum looks fine?
Community consensus is to work the problem in order: engine power delivery first, then worn vibratory internals, before blaming the drum shell itself. The usual checklist is exciter oil level and condition, drum isolator/mount condition, bolt torque around the exciter housing, and evenness of drum wear. A growling or knocking sound when vibration is engaged is read as exciter bearing wear rather than a hydraulic fault. Because the exciter bearings and seals run under continuous heat and shock load, the service interval discussed for this drum is around 3 years or 3000 hours, and problems tend to surface once a machine has run well past that window.
What causes sluggish or one-direction-weak travel on the CB22?
The diagnostic order favored by mechanics is hydraulic pressure first, then drive motor case-drain flow, before condemning the propel pump outright. Metal found in the hydraulic filter or return oil is treated as the red flag for a failing drive motor or pump, not something to write off as routine wear. Exact charge pressure and case-drain specs vary by configuration/series, so pull the figure from the specific machine's own service literature rather than comparing against a different-size compactor.
What should I know about the water spray and scraper system before assuming it's broken?
The water spray system's automatic on/off logic, tied to the propel lever going into and out of neutral, is called out repeatedly as the first thing to check before condemning the spray pump or nozzles, since a bad neutral switch reads the same as no water reaching the drum. Nozzle position affects drum coverage, and clogged nozzles from scale or debris in the water tank are treated as routine upkeep rather than a defect. Scraper bar adjustment and contact against the drum is the other recurring item; a loose or worn scraper lets material pick up on the drum and shows up directly in the finished mat.
Are there known electrical or sensor quirks with this machine?
The industrial control module shared across this compactor size class is described as a lower-volume part, so sourcing a replacement outside dealer channels is harder than for higher-volume engine families. On this general Cat utility-compactor family, relay and fuse faults are described as the first electrical check when high or low vibrate stops responding, before condemning the exciter solenoid or the control module itself. Exact wiring and relay layout varies by configuration/series, so confirm against the specific machine's own wiring diagram rather than a sibling model's. Standard Cat diagnostic access is built into this compactor line for pulling active and logged fault codes.
What wears out on a tandem drum machine like the CB22 instead of an undercarriage?
With no tracks or roller undercarriage, the wear pattern discussed most is at the drum isolator mounts and the articulation/center-pivot joint. Isolators harden and crack with age and heat, transmitting more vibration into the frame and operator station over time, which owners describe as the machine getting rougher even when the exciter itself tests fine. Articulation joint and steering cylinder pin play is the other spot to check, since side-to-side slop there shows up as wandering travel or an uneven compaction pattern left on the mat.
What should I check before buying a used CB22?
Start at the operator station: confirm gauges, horn, back-up alarm, and lights all function, since general upkeep there tends to reflect how the rest of the machine was treated. Inspect the drum shell for pitting or scarring and check remaining shell thickness, then check isolator mount condition and listen for exciter bearing noise under vibration. Run a hydraulic pressure check on the propel system and look for metal in the filter or return oil. Pull the engine's service history and specifically ask whether the oil pump idler gear dowel issue on the C1.5 was ever inspected or repaired. Also factor in that the CB22B has since been superseded by newer utility compactor models, so dealer parts stocking and support gradually shift toward the current line, which is worth weighing against resale value and future parts lead time.
