Caterpillar 16G

Maintenance schedule, common problems & OEM parts breakdown

The Caterpillar 16G is a heavy-class articulated motor grader, the largest grader Caterpillar built during its classic G-series era and aimed at mining, airfield, and large-scale road work rather than routine highway maintenance. It runs a Caterpillar 3406T turbocharged diesel, an inline-six of roughly 14.6 L (891 cu in), with factory ratings that moved over the production run from around 250 hp (186 kW) up to about 275 hp (205 kW) — check the dataplate for the rating on a given unit, since output varies by series and year. Operating weight falls in the 24.5-27.3 tonne (54,000-60,150 lb) range depending on configuration and which weight figure is quoted, and production ran from 1973 to 1995 (some spec sheets reflect only the final years' configuration) as the direct successor to Caterpillar's original No.16 grader (1963-1973), a mechanically steered machine with only hydraulic assist. The 16G came with a standard 4.88 m (16 ft) moldboard, an 8-speed forward/reverse powershift transmission, air brakes, and the front-mount ripper or scarifier attachments typical of graders in this class.

Through its long production run Caterpillar refined the 16G's output and hydraulic circle, drawbar, and moldboard architecture rather than issuing a mid-cycle name change, carrying over much of that design from the smaller 12G and 14G graders built alongside it. Caterpillar retired the G-series in 1995 in favor of the H-series (16H), which added a further uprated turbocharged engine and, on some models, all-wheel drive; the 16-class name later continued through the M-series and is used today on unrelated current-generation machines badged 16M3 and 16/16 GC. In the used and parts market the 16G still matters because a large working population remains in mining, quarry, and airfield service decades after the last unit left the factory. Its Cat 3406-family powertrain and driveline share design lineage and some component commonality with other classic G-series graders, which keeps rebuild parts and service knowledge realistically available for owners running these machines well past their original design life.

16G fluids & capacities

SystemCapacityRecommended fluid
Engine crankcase, incl. oil filter (Cat 3406-series direct-injection turbo diesel)34 L (9.0 US gal)Cat DEO (Diesel Engine Oil) or equivalent heavy-duty diesel engine oil meeting Cat's CD/CE-level spec. Grade by ambient temperature: SAE 10W in cold climates, SAE 15W-40 for general/moderate service, straight SAE 30 or 40 in sustained hot climates. Engine suffix cited across sources for this model varies (3406, 3406C, 3406T DI) reflecting different build years/regions of the 16G run.
Cooling systemNot confirmed for this exact serial range across available documentation. Full-system fill for this engine family typically falls in the 55-70 L (14-18 US gal) band, but treat this as indicative only — verify against the machine's OMM or a dealer before ordering coolant.Full-formula or extended-life ethylene-glycol antifreeze/coolant, mixed to the concentration the OMM specifies for local climate (Cat's coolant program for this vintage predates the later Cat ELC branding but follows the same glycol/inhibitor logic).
Fuel tankNot documented for this exact serial range in available sources — verify tank capacity with a dealer or the machine's OMM before planning refuel intervals.No. 2-D diesel fuel (or ultra-low-sulfur diesel equivalent). No. 1-D or a winter-blend diesel is recommended in cold climates per general Cat fuel guidance for this engine family.
Powershift transmission and differential (combined compartment)114 L (30.1 US gal)Cat TDTO (Transmission/Drive Train Oil). Grade by ambient temperature: SAE 10W in cold climates, SAE 30 for general/moderate range, SAE 50 in hot climates.
Tandem final drive housings, each side125 L (33.0 US gal) per sideCat TDTO, same climate-based grade selection as the transmission/differential: SAE 10W/30/50 depending on ambient temperature.
Circle drive (swing-frame) unit8 L (2.1 US gal)Cat TDTO, same climate-based grade selection as the transmission and tandem drives.
Front wheel spindle housings, each side1 L (0.26 US gal) per sideCat TDTO, same climate-based grade selection as the drivetrain components.
Hydraulic system (implement and steering circuits, incl. tank)114 L (30.1 US gal)Cat TDTO is used as the shared hydraulic/drive-train fluid on this generation of grader — SAE 10W for cold climates, SAE 15W-40/30 for general service. A dedicated ISO 46 anti-wear hydraulic oil is an accepted alternate fill where ambient temperatures stay moderate.
Grease — chassis, circle, and linkage fittingsSpec only, no bulk system capacity. Lubricate per the OMM grease-interval chart.Cat MPGM-type multipurpose EP-2 lithium-complex grease; some articulation and wear-pad points call for a moly-fortified EP-2 grease. Use an NLGI 1 or arctic-grade grease in sustained sub-zero climates.

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

Servicing the 16G beyond the schedule

Predictive Maintenance & Fluid Analysis

Pull engine oil samples from the 3406T turbocharged diesel at every oil change and watch for turbo bearing metals and soot loading, since these engines run under heavy sustained load in mining and airfield grading. Sample transmission/torque converter oil for clutch-pack wear metals, and check hydraulic oil condition given how many 16Gs now run mixed or non-factory fluid after decades of service. Track coolant corrosion-inhibitor level closely; the 3406T runs hot under turbocharged load and neglected coolant chemistry accelerates cylinder liner pitting.

Corrective & Common Repairs

Expect circle wear strip and shoe replacement on the top-adjust circle design, plus drawbar ball-socket wear from decades of articulation stress at the frame hitch. The 3406T's turbocharger is a common failure point — watch for shaft play, oil seal leakage, and boost line cracks. Powershift transmission clutch packs wear faster on machines used for blade-to-grade finish work with frequent direction changes. Because the 16G runs air brakes rather than hydraulic brakes, check the air compressor, governor, and reservoir drain valves for leaks and moisture buildup.

Overhaul & Rebuild Points

Major rebuild points on the 16G center on the torque converter and transmission clutch packs, the turbocharger core, and the circle drive gear and wear strips, all of which see heavy cyclic load from grading and fine-finish passes. Tandem final drive housings need gear and bearing inspection at overhaul given the sustained load each tandem set carries on this class of grader. Moldboard cutting edges, end bits, and drawbar wear plates are wear items best replaced as a set rather than individually to keep the blade tracking true.

Seasonal & Environment Servicing

In dusty mining and quarry environments, service the air cleaner far more often than the standard interval and inspect the turbocharger intake ducting for dust ingress that accelerates 3406T wear. In cold climates, verify coolant freeze-point protection and consider a lighter hydraulic oil viscosity grade for winter cold starts on the circle, drawbar, and blade-lift circuits. Purge grease at the circle, drawbar ball-socket, and articulation pins after wet-season or wash-down work to force out water and grit before it scores the pins and bushings.

16G attachments & work tools

Moldboard / grading blade

16G-class graders carry a 4.27 m or 4.88 m (14 ft or 16 ft) moldboard, about 787 mm tall with a 25 mm cutting edge. The blade rides on the drawbar-circle-moldboard assembly with hydraulic circle drive, side shift and tip; blade angling is manual or hydraulic depending on the arrangement ordered.

Front scarifier

Attaches to the front lift group ahead of the front axle for light-duty work such as breaking up compacted material, thin asphalt, or a rocky subgrade before final grading. This mount is a low-cost option and shares its bracket pattern with other graders in the 14G/16G/16H tool-carrier family.

Mid-mount scarifier

Fitted between the front axle and the moldboard on its own lift group and hydraulic cylinder. Gives better depth control and operator visibility than a front-mounted unit and can fracture harder material.

Rear ripper/scarifier

Mounted over the tandem drive at the rear so drive-tire weight adds to ripping force; useful for working into corners or along walls. Heavy-duty ripper shanks and lighter scarifier-style shanks are interchangeable on the same beam depending on the job, and the unit needs its own rear hydraulic lift kit.

Push block

Bolts to the front nose plate. Doubles as a counterbalance for a rear ripper and as a push point when the grader is used to move other equipment or windrowed material.

Snow V-plow

Front-mounted V-shaped plow with a nose piece and dividing wings that dig into packed or drifted snow and throw it to both sides. Used in place of, or in addition to, the standard moldboard for winter service.

Snow wing

Auxiliary moldboard, usually mounted on the right side, that widens the cleared path when run with the standard blade or the V-plow. Mast-type wings are built for throwing deep drifted snow; mastless wings clear and bench shoulder snow, ramping up banks of roughly 40 degrees.

Mounting / coupler system

Motor graders in this class do not use a quick-coupler. Work tools bolt or pin to dedicated lift groups (front, mid, rear) sized to the grader's frame width and lift-arm geometry. Front lift-group brackets and blade attaching hardware are common across the 14G/16G/16H platform, allowing some cross-model tool fitment within that family.

Hydraulic kit requirements

Mid-mount and rear ripper/scarifier attachments require a dedicated hydraulic lift kit (cylinder, valve section, and hose routing into the grader's implement circuit) beyond the base blade circuit. Front scarifiers are typically simpler, pin-adjusted or single-cylinder setups.

Cab and guarding options

Cabs were ordered as open canopy or enclosed, with ROPS/FOPS protection available depending on configuration and era. Optional bottom guarding for the transmission and filters, and front axle/steering-cylinder guards, are documented for this size class of grader for quarry and forestry-type duty; confirm exact factory availability for a specific 16G serial range with a dealer, since some of this guarding is best documented on later graders in the same size class.

16G serial number reference

The serial plate on a 16G is mounted on the main frame, commonly on the right-hand side near the front, or on the upper frame close to the cab depending on the specific plate fitment; if the plate is missing, the number is stamped directly into the frame steel in the same area. Read the plate as a 3-character prefix (e.g. 93U) followed by the sequential unit serial number, with no dash between them. The 16G predates Cat's post-2000 17-character PIN format, so the plate shows only this short prefix-plus-serial style number, not a full PIN string.

Frequently asked questions

What engine does the Caterpillar 16G motor grader use?

A Caterpillar 3406T turbocharged diesel inline-six, about 14.6 L (891 cu in) displacement. Factory ratings ranged from around 250 hp (186 kW) early in the model's run to roughly 275 hp (205 kW) later in production, so this varies by series and year — confirm the rating from the dataplate on a specific machine.

What is the operating weight of a Caterpillar 16G?

Operating weight with standard equipment runs around 24.5 tonnes (about 54,000 lb); weight figures quoted as shipping weight with ballast and attachments run closer to 27.3 tonnes (about 60,150 lb). Treat this as a range rather than a fixed number, since it varies by configuration, tire choice, and attachments.

What replaced the Caterpillar 16G?

Caterpillar discontinued the 16G in 1995 in favor of the H-series (16H), which added an uprated turbocharged engine and, on some models, all-wheel drive. The 16-class name continued afterward through the M-series and is used today on unrelated current-generation large graders badged 16M3 and 16/16 GC.

What 16G owners discuss

What engine is actually in the 16G, and how much power does it really make?
The 16G (93U serial prefix, produced roughly 1973 to the mid-1990s, with most machines tracked in spec databases from the 1987-1995 window) runs the Cat 3406 family - a turbocharged, direct-injection inline six displacing 14.6 L (891 cu in). Quoted output is 250 hp (186 kW) on earlier production and 275 hp (205 kW) on later machines, so treat the number as varying by series/year rather than fixed. A few listings mix this engine up with the smaller 3306, but the 14.6 L displacement figure and the serial-prefix breakdown point to 3406/3406T, not 3306. On tired examples, owners flag the usual 3406T quirks: turbo bearing wear showing up as oil in the intercooler piping, blue-black smoke under load, and rising oil consumption as rings and valve seals age. Worth a compression/blow-by check and a look at the intercooler boot on any high-hour unit before buying.
What's the common transmission complaint on this machine?
The 16G uses a direct-drive powershift with eight speeds forward and reverse, shifted through a cable-linked mechanical control valve - this generation predates Cat's onboard electronic transmission controls used on later H and M-series graders. The recurring owner complaint is losing the upper range: gears 1-4 work fine but 5-8 won't engage, which points to the high-range clutch pack not applying. First check is pulling the transmission case suction screens and looking for flakes of burnt clutch friction material before assuming a control-side issue like cable adjustment. If it's confirmed internal, the whole transmission has to come out as a unit - a heavy job, in the neighborhood of a ton on the hoist - so budget for this as a major line item on any 16G with unknown maintenance history.
What wears out on the circle drive and hydraulics?
On high-hour circle drive hydraulic motors, rebuild shops commonly find the worm gear and pinion badly worn along with the internal bearings and the drive clutch assembly - it's a package failure, not a single part. Symptoms owners describe: slow or uneven circle rotation, grinding noise during blade rotation, and visible hydraulic leakage at the motor or circle drive housing. Because this assembly controls blade position accuracy and can let the moldboard swing unexpectedly if the drive binds or slips mid-cut, have your dealer verify circle drive and clutch condition before putting the machine back into grading work.
What are the typical wear points instead of undercarriage, since a grader doesn't have tracks?
In place of undercarriage wear, the 16G's recurring consumables are the tandem drive housings, wheel lean cylinders, and the circle/drawbar/moldboard wear strips and shims. Community reports on wheel lean cylinders describe rod pitting from corrosion and abrasion letting contamination past the seals, which then scores the bore and piston seals and shows up as internal leak-by (cylinder drifts under load). On the tandem cases, a failed brake seal is the classic way oil ends up filling the tandem housing, so check oil level and condition at both tandem ends as a routine item, not just when a leak is visible externally.
Does the 16G have sensor or electrical gremlins like newer machines?
Not in the way people mean with modern electronic-monitored graders. This generation has no factory diagnostic codes to chase - it's a fully hydraulic-mechanical control machine with basic charging and starting circuits only. Community troubleshooting for no-start or intermittent no-crank complaints starts with corroded battery terminals and connections, chafed or worn harness sections causing an open or short, and starter overheating from repeated long cranking attempts on a tired engine (starters are duty-rated for short bursts, not extended cranking). Walk the wiring and clean/tighten grounds and battery connections first, rather than jumping straight to starter or alternator replacement.
What should I check when looking at a used 16G before buying?
Consensus checklist from experienced buyers: inspect the circle surface for uneven wear (a sign of misalignment that chews up the pinion teeth), check the frame for cracks and look closely for fishplates welded over prior crack repairs, work the articulation joint for play or evidence of past repair, and check the moldboard cutting edge for straightness and center-cupping from rock/soil wear. Check underneath and around the machine, running, for any fluid weeping - engine, hydraulic tank, and tandem cases. Ask for maintenance records to gauge real running condition versus hour meter. On the test drive, cycle every forward and reverse gear to confirm the high-range clutch engages cleanly (see the transmission note above) - this alone can separate a fair-priced machine from an expensive rebuild. Given the structural and safety weight of frame and articulation condition, have your dealer verify these before finalizing a purchase.
How do operators today rate the 16G against newer graders?
Owners who've run both generations generally still respect the 16G for its simple, fully hydraulic (non-electronic) control feel and good operator sightlines to the moldboard, and some crews prefer it specifically for finish and trim grading over newer electronically-controlled machines. The trade-off community members raise: this is a design from the 1970s-90s, so parts depth and dealer support have thinned compared to current production, cab comfort and ROPS design are dated next to H/M-series graders, and sourcing the tandem tire size (23.5-25) can take longer than mainstream sizes. Buyers going into a 16G purchase should expect to lean on independent hydraulic/driveline rebuild shops as much as the Cat dealer network for major components.
