Caterpillarmotor grader
Caterpillar 16
Maintenance schedule, common problems & OEM parts breakdown
The Caterpillar 16 is Cat's large, articulated-frame, tandem-drive motor grader, built for haul-road construction and heavy grading in mining and large civil projects. It debuted in 1963 as a scaled-up answer to the No. 14, running a D343T six-cylinder diesel rated near 168 kW (225 hp) and weighing about 22,500 kg (49,600 lb). A 1970s redesign created the 16G, with full hydraulic circle and blade controls replacing cable-and-lever steering and an articulated frame becoming standard; the G and H series that followed carried a 3406-family turbocharged diesel, roughly 186-249 kW (250-334 hp), with operating weight climbing toward 24,500-31,800 kg (54,000-70,100 lb) depending on configuration. The line moved to the Cat C13 ACERT with the Variable Horsepower system in the M series starting in 2006, rated 216-259 kW (290-348 hp) net; the current 16M3, sold since 2015, ships in Tier 2, Tier 3, or Tier 4 Final emissions configurations with single or dual rear tires, an optional drawbar-mounted scarifier/ripper, and an optional automatic lubrication system for the circle and drawbar joints, with operating weight running roughly 26,000-35,700 kg (57,450-78,640 lb) depending on ballast and attachments. There is no separate successor model - the 16 designation has run continuously for six decades, with Cat's larger 24 sitting above it as a distinct flagship mining grader rather than a replacement.
Each generation changed how the 16 is driven and serviced more than what it does. The 16G's move to full hydraulic controls cut operator fatigue and made blade control repeatable. The 16H carried that forward with tighter turbocharged engine calibration through the 1990s and 2000s emissions rules. The 16M replaced up to fifteen control levers and a steering wheel with two electro-hydraulic joysticks and added the VHP system that shifts horsepower to match gear and load automatically. The 2015 update to 16M3 lengthened the rear frame, thickened the hitch plates, and added bumper-mounted counterweight castings for better stability and longer circle/drawbar life on haul roads. Because the line has run essentially unbroken since 1963, a large population of G- and H-series machines is still grading county roads, quarries, and mine sites worldwide - their mechanically simple powershift drivetrains and 3406-family engines, shared with trucks and generator sets, keep rebuild parts and used components easy to source. M-series units are now entering the used market in volume as mining fleets cycle out, keeping steady demand for circle and drawbar wear components, tandem and final-drive parts, and C13 engine kits.

Servicing the 16 beyond the schedule
Predictive Maintenance & Fluid Analysis
Run S·O·S oil sampling on every 250-hour engine oil change, whether the machine carries the 3406-family diesel (G/H) or the C13 ACERT (M-series) - both run heavy haul-road duty cycles that load turbos and injectors hard. Sample transmission, differential/final drive, tandem case, and hydraulic tank oil at each drain to catch planetary gear and circle-drive wear before it reaches the moldboard. Track coolant condition and corrosion inhibitor level, and measure circle and drawbar wear-strip clearance at every 250-hour interval - it's the earliest warning of blade-control looseness.
Corrective & Common Repairs
Circle and drawbar wear inserts take the brunt of constant blade-to-ground loading and need shimming or replacement well before other components on this grader. Watch for drawbar ball-and-socket play, worn moldboard cutting edges and end bits, and articulation-hitch pin wear on machines that spend their life turning tight haul-road corners. Tandem case oil leaks past planetary seals and steering-cylinder seal weeping are common on higher-hour G/H-series units; on M-series machines, check electro-hydraulic joystick calibration and VHP solenoid faults first when power feels inconsistent.
Overhaul & Rebuild Points
High-hour 3406-family and C13 ACERT engines both reach inframe-overhaul territory eventually - turbo, injectors, liners, and piston kits are the usual rebuild list once oil analysis trends turn. Tandem cases need planetary gear and sprocket/chain rebuilds at major overhaul intervals, and the circle gear and segment teeth wear enough on haul-road machines to justify a full circle rebuild or replacement. Drawbar center-shift wear plates and powershift transmission clutch packs are the other big-ticket items when this grader reaches its second or third life cycle.
Seasonal & Environment Servicing
Mining and haul-road sites push dust into air filters and hydraulic tank breathers faster than the standard interval assumes - shorten those checks in dry, dusty conditions. Cold-climate units need coolant freeze-point testing, block-heater checks, and cold-start aid inspection before winter; hot, dusty pits call for more frequent radiator and hydraulic-cooler core cleaning to keep the 3406-family or C13 engine from running hot under load. Standing water or mud sites wear articulation and drawbar grease out quicker than the 50-hour default, so bump circle/drawbar lubrication frequency accordingly.
16 fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| 0110-03/04 | Engine Coolant Temperature Sensor circuit voltage above normal (03) or below normal (04); ECM cannot read a valid coolant temperature signal | Open or shorted sensor wiring, corroded connector, or failed coolant temperature sensor | Inspect sensor connector and harness for damage or corrosion, check sensor resistance against spec, replace sensor if wiring tests good |
| E360 | Coolant Temperature High - condition-based warning that actual engine coolant temperature has exceeded the safe operating range | Low coolant level, blocked or dirty radiator core, failed thermostat, weak water pump, or slipping fan drive | Idle down and stop the machine, check coolant level and radiator core cleanliness once cooled, verify thermostat and fan operation before returning to work |
| 0100-03/04 | Engine Oil Pressure Sensor circuit voltage above normal (03) or below normal (04); ECM cannot read a valid oil pressure signal | Damaged sensor wiring, bad connector, or failed oil pressure sensor | Inspect sensor harness and connector, test sensor output, replace sensor if the circuit checks out good |
| 0190-08 | Engine/Crankshaft Speed Sensor abnormal frequency, pulse width, or period | Incorrect sensor air gap, damaged timing or tone wheel, or a failing speed sensor | Check and reset sensor air gap to spec, inspect the tone wheel for damage, replace the sensor if the fault persists |
| 0168-01 | Electrical System Voltage low, most severe level; system/battery voltage below normal operating range | Weak or discharged batteries, loose or corroded battery cable, failing alternator or charging system | Load-test batteries, check charging system output, inspect battery cables and ground connections |
| 0041-03/04 | 8 Volt DC Sensor Supply circuit voltage above normal (03) or below normal (04); this is a shared reference supply feeding several engine sensors | Short to a higher voltage source, or short to ground on the 8V reference circuit | Disconnect sensors fed by the 8V supply one at a time to isolate the shorted component, repair or replace as needed |
| 0247-09 | Data Link (J1939) abnormal update rate; communication fault between the engine ECM and other machine controllers | Damaged CAN wiring, missing or failed termination resistor, or a module not communicating on the data link | Check data link wiring and termination resistance (about 60 ohms across the twisted pair), confirm all ECMs are powered and communicating |
| 0102-03/04 | Boost/Intake Manifold Pressure Sensor circuit voltage above normal (03) or below normal (04) | Damaged sensor harness, plugged or damaged sense line, or a failed boost pressure sensor | Inspect sensor wiring and sense line for damage or blockage, test the sensor, replace if faulty |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
16 attachments & work tools
Standard moldboard
Standard blade is 4.9 m (16 ft) wide, 25 mm (1 in) thick, with hydraulic side shift and tip. Side shift travel is roughly 740 mm left / 790 mm right (29.1 in / 31.1 in), max depth of cut is about 470 mm (18.5 in), and max lift above ground is about 400 mm (15.7 in). This blade size is standard across the current 16 and prior 16M/16M3 large-grader generation.
Cutting edges and end bits
Standard curved cutting edge is 203 x 25 mm (8 x 1 in) through-hardened DH-2 steel; an optional flat edge of about 254 x 35 mm (10 x 1-3/8 in) is offered. Serrated versions of both flat and curved edges are available, plus carbide-insert edges rated for up to roughly 20x the life of a standard edge in high-abrasion, low-impact ground.
Mining Bit System / GraderBit GET
For the large-frame 16-class graders, an upgraded Mining Bit System (heavier version of the standard GraderBit system) is offered, with multiple bit-tip designs and several serration patterns sized to pass 15-60 mm (0.6-2.4 in) of aggregate without packing.
Rear ripper/scarifier
Factory rear ripper mounts at the drawbar with 7 shank holders, adjustable spacing of about 445-508 mm (17.5-20 in), and max ripping depth near 452 mm (17.8 in). Rated penetration force is about 135 kN (30,300 lbf) and pry-out force about 194 kN (43,700 lbf); shank count/spacing and force ratings vary by configuration.
Mid-mount scarifier
A mid-mount straight scarifier is also offered as an alternative to the rear ripper, with variable shank spacing for tighter passes to loosen or condition hard material and mixed soils ahead of the moldboard.
Front blade / dozer blade
Straight front blade and hydraulic angle front blade (about 30 degrees hydraulic angle left or right) mount to the front frame/nose area for spreading, debris removal, and tight-corner grading. A U/V convertible blade variant is also offered, switching between straight, angle, U- and V-configurations via auxiliary hydraulics and an optional diverter valve; sizes are matched to the machine class rather than fixed for the 16 specifically.
Push block
A push block mounts to the nose plate and serves two roles on this class: counterweight to balance a mounted rear ripper, and a push point when the grader is used to assist other equipment.
Snow wing
Mast-type and mastless snow wings mount to the right side of the machine/moldboard for wide-path snow clearing beyond the standard blade. Mastless wings can bench drifted snow up to about a 40-degree slope; mast-type wings are used for deep, heavily drifted snow. Offered across the large-grader lineup that includes the 16.
Front-mounted broom
A front-mounted hydraulic broom attachment is offered for debris clearing on roads and intersections. Exact broom width/spec tied specifically to the 16 model is not documented in available sources; confirm sizing with dealer for this frame size.
Blade extensions
Bolt-on moldboard extensions widen the effective grading path and are marketed as raising per-pass productivity by up to about 20%. Offered generally across the Cat grader line, sized to the moldboard.
Drawbar-circle-moldboard mounting system
The moldboard is not attachment-coupler mounted; it rides on a factory drawbar-circle-moldboard (DCM) linkage with a 3-bolt blade bracket, six drawbar shoes with replaceable wear strips, and top-adjust circle wear strips. A circle-drive slip clutch protects the driveline from shock loads during grading and ripping.
Technology add-ons
Optional Cat Detect package (surround camera, smart object-detection camera, rear camera) and Cat Grade Connectivity/grade-control compatibility are offered as factory or dealer-installed technology options on this machine.
Guarding and mining-access options
Optional guarding includes rear fenders, front axle cylinder guards, and debris guards to protect components in haul-road and mining duty. Mining-oriented access options include grab handles, nonslip steps, tie-off points, and optional fall-protection platforms with dual access paths for service.
Factory trim/configuration variants
The current 16 line is offered in a mining/haul-road focused base configuration and a lower-spec '16 GC' (general construction) trim aimed at cost-sensitive road maintenance work; both use the Cat C13 engine. The 16 is positioned for haul trucks up to about 150 ton payload class or as a companion machine to a 24-size grader in larger fleets.

16 serial number reference
The PIN/serial plate is riveted to the grader's main frame, typically on the right-hand front frame rail near the front axle and steering gear housing. If the plate is missing, the number is often stamped directly into the frame in the same area. Read the first three characters as the prefix, which pins down the model generation, configuration, and engine fitted; the digits after it are the sequential unit number within that prefix's production run.
| Prefix | Identifies | Notes |
|---|---|---|
| 49G | Original Cat No. 16 motor grader (1963 launch) | First of Caterpillar's large motor graders. D343T diesel paired with a powershift transmission, the first powershift used on a Cat grader. Roughly 1,400 units built from 1963 before the line was redesigned with an articulated frame as the G-series. |
| 93U | 16G motor grader | Mechanical direct-injection 3406 diesel. Built 1987 through 1995. |
| 6ZJ | 16H motor grader, North America (16H NA) configuration | 3406C-family diesel. Mid-1990s into the early 2000s. Confirm exact engine rating with dealer, this build is documented less thoroughly than the export ATS line. |
| ATS | 16H motor grader, standard/export configuration | 3196 diesel. Sold alongside the 6ZJ North America build within the 16H generation, outside North America. |
| B9H | 16M motor grader, early production run | C13 ACERT diesel, rated up to roughly 337 hp with Variable Horsepower (VHP). Marks the start of the 16M generation, introduced around 2006 as the 16H replacement. |
| R9H | 16M motor grader, later production run | C13 ACERT diesel. Later serial range within the 16M generation; exact start year not clearly documented, confirm with dealer. |
| E9Y | 16M3 motor grader, early production run | C13 ACERT diesel. Early build range from the 16M3 launch in 2015. |
| N9Y | 16M3 motor grader, later production run | C13 ACERT diesel. Later serial range within the current 16M3 generation. |
Frequently asked questions
What engine does the Caterpillar 16 motor grader use?
It depends on the series. The original 1963-era 16 ran a D343T six-cylinder diesel rated near 168 kW (225 hp). The 16G and 16H generations used a 3406-family turbocharged diesel, roughly 186-249 kW (250-334 hp) depending on year and configuration. The current 16M and 16M3 use the Cat C13 ACERT with the Variable Horsepower system, rated 216-259 kW (290-348 hp) net.
What is the operating weight of the Caterpillar 16 motor grader?
It varies by series and configuration. Early 1963-era machines weighed about 22,500 kg (49,600 lb). G- and H-series units run roughly 24,500-31,800 kg (54,000-70,100 lb) standard to maximum operating weight. The current 16M3 spans about 26,000 kg (57,450 lb) standard to 35,700 kg (78,640 lb) fully equipped, depending on ballast and attachments.
What replaced the Caterpillar 16 motor grader?
Nothing replaced it outright. The 16 has run as a continuous model line since 1963, updated through the 16G, 16H, 16M, and current 16M3. Cat's larger 24 motor grader sits above it for the biggest mine haul-road jobs, but it is a separate, larger-class machine rather than a direct successor.
What 16 owners discuss
What engine does a Caterpillar 16 motor grader run, and does it change across the years?
Yes. The "16" badge covers several distinct machines with different engines depending on generation. The original 1963-era No. 16 ran a D343T diesel rated around 168 kW (225 hp). The 16G switched to a mechanical Cat 3406, roughly 187 kW (250 hp). The 16H generation split by market: standard/export units got a 3196 ETA (198-213 kW / 265-285 hp), while North America-tuned units got a 3406C DITA (around 205 kW / 275 hp). The 16M and 16M3 moved to a Cat C13 ACERT VHP, base 221 kW (297 hp) rising to 233 kW (312 hp) in upper gears via Variable Horsepower Plus; some early 16M units left the factory filled with summer-weight oils that caused cold-start trouble in extreme cold (around -40 and below), so confirm winter-spec fluids on any 16M sourced from a warm climate. Current-production 16 (2021 on) keeps a C13 base but adds full Tier 4 Final/Stage V aftertreatment. Read the serial plate before ordering parts or fluids - engine, transmission and hydraulic specs differ enough between generations that documentation for one doesn't carry over to another.
Are there known transmission or powertrain problems on early 16M graders?
Early-build 16M units had a rough start. Owners running small fleets reported multiple transmission failures well under normal wear-out hours, traced to factory assembly errors - bolts in the flywheel and torsional coupler area not torqued to spec. Caterpillar issued a product improvement covering the transmission clutch pistons, the torsional coupler, and the flywheel where needed. A separate quirk some operators flagged: light blading downhill in 2nd or 3rd gear could trigger an unexpected upshift as high as 5th gear with no warning. It reportedly took Caterpillar several years of flashfile updates to settle the design down. If you're running or buying an early 16M, confirm the current flashfile is loaded and that the PIP work was completed - have your dealer verify the transmission and torsional coupler condition before returning the machine to service.
What electrical or sensor issues come up on 16-series graders?
On the more automated M-generation machines, the cross slope control system is the sensor most operators end up chasing. If the cross-slope sensor is disturbed - removed for service, bumped, or replaced - it needs to be recalibrated, or the blade will hunt for the wrong angle during grading. Some operators just disable cross slope control rather than troubleshoot a sensor that's drifted out of calibration mid-shift. If automated grade control looks erratic on one of these machines, check sensor mounting and wiring at the circle/blade area and recalibrate before assuming a hydraulic or mechanical fault.
What hydraulic wear item shows up most on these graders' wheel-lean and steering circuits?
Wheel-lean cylinders are a recognized wear point across the whole Cat grader lineup, 16-series included. Seal wear inside the cylinder bore causes internal leakage that bleeds off before an operator notices - hydraulic efficiency can drop noticeably before it's visually obvious. Left unchecked, contamination from a failing cylinder can spread into the rest of the circuit, including pumps and valves. Watch for a lean angle that drifts back toward center on its own, or a machine that needs the lean reset more often than it used to. A cylinder drift/bypass check is the standard diagnostic before blaming the control valve or pump.
What's the main structural wear pattern operators watch on the moldboard circle?
The circle-and-drawbar interface is the classic high-wear zone on any Cat motor grader, 16-series included. The circle itself is a durable forged casting, but it rides on sacrificial wear strips - composite or metallic - at the circle shoes and drawbar contact points, designed to wear instead of the circle or drawbar. Composite strips outlast metallic ones when running unlubricated and are now the standard fit on current-production Cat graders. Uneven wear here shows up as slop in circle rotation or blade chatter under load. Treat strip replacement as a routine service item, not a sign the machine is worn out.
Does the DEF/DPF system on the current Tier 4 "16" cause downtime?
Yes, this is a common complaint on Tier 4 Final Cat engines generally, and the current 16's C13 is no exception. Forced and passive regeneration cycles interrupt production, and operators running haul-road grading schedules flag it as a real productivity hit compared to earlier, non-emissions-controlled generations. Typical fault codes tied to this system flag DPF regen switch problems or DPF inlet temperature faults. Keep duty cycles long enough to let passive regen happen naturally and don't ignore early DPF warning lamps - letting the condition escalate to a forced regen or a derate costs more downtime than managing it proactively.
What should I check before buying a used Caterpillar 16?
Start with the serial plate on the frame near the front articulation hitch or center hinge - the prefix tells you which generation and engine you're actually buying. A mechanical-era machine is a completely different animal from an M-generation or current Tier 4 unit, so don't assume parts or fluid specs carry over. Beyond that, the checklist is the same as any large grader: look under the machine for hydraulic weeping at the circle drive housing, cylinders, and hose runs; rotate the circle and check for slop or uneven wear at the shoes and drawbar wear strips; check the moldboard cutting edge for cupping and confirm it hasn't worn far enough to gouge the moldboard itself; inspect the frame at the front articulation hitch and center hinge for cracks or fishplate repairs; cycle the wheel-lean function and watch for drift back toward center, a sign of worn lean-cylinder seals; and pull maintenance records to confirm PIP or recall work was completed on M-generation units. On any hydraulic or steering-circuit finding that looks marginal, have your dealer verify it before relying on the machine in service.
