Volvo motor graders are precision machines — combining powerful blade control, articulated steering and all-wheel drive to deliver the flattest, most accurate road surfaces in the industry. Whether maintaining haul roads in a quarry, finishing base layers for a highway, or grading a township road, the G-series demands reliable parts and consistent maintenance to stay productive. This guide covers every major component system for Volvo G710 through G990 motor graders, with verified parts pages for each model.
Volvo Motor Grader Model Overview
The Volvo G-series spans two main generations: the older G700-series (G710 through G740) and the newer G900-series (G930 through G990). Both share the same fundamental architecture — a front-mounted blade, rear tandem axle drive, and a centrally positioned cab — but differ significantly in engine output, blade length, and electronic control sophistication.

Most Common Replacement Parts for Volvo Motor Graders
Motor graders work long shifts in highly abrasive conditions. Blade systems, articulation joints, circle drive gears, and tandem drive components take the most punishment. Here are the systems with the highest parts replacement frequency.
1. Blade, Circle & Drawbar System
The moldboard blade, circle ring gear, drawbar, and blade lift cylinders are at the very heart of grader productivity. Circle drive pinion gear wear, blade pitch cylinder seals, and drawbar ball socket assemblies are the most frequently replaced components in this system. Blade wear edges and end bits are consumables that need replacement at almost every major service. These components are unique to motor graders and must be sourced with exact model and serial number matching. Browse grading and hydraulic system parts.
2. Hydraulic System
Motor graders use hydraulics for blade lift, blade pitch, circle drive, articulation steering, scarifier lift, and front axle lean. The number of simultaneous hydraulic circuits means that pump wear, control valve wear, and hose fatigue accumulate faster than on most other machine types. Hydraulic pump rebuild kits, main control valve seals, and cylinder seal kits are among the highest-demand parts for G-series graders. Browse all hydraulic parts.
3. Tandem Drive & Rear Axles
Volvo motor graders use a tandem rear drive system with two axles connected by a chain drive. The tandem chain, sprockets, and axle shaft seals are wear items that require inspection at each major service. Differential seals, axle bearing sets, and tandem case gasket kits are also frequently needed. Browse power transmission parts.
4. Articulation & Front Frame
The articulated frame design gives motor graders their steering versatility — but the articulation joint itself is a wear point that needs regular attention. Articulation pin sets, steering cylinder seals, and front axle lean cylinder rebuild kits are regular service requirements. Browse frame and axle parts.
5. Engine
G700 and G900 series graders use Volvo six-cylinder engines producing 175 to 275 hp. Standard engine service items — air filters, fuel filters, injector sets, coolant hoses, water pump kits, and turbocharger assemblies — are the most common orders. Engine overhaul gasket sets and liner kits are needed at major rebuild intervals. Browse engine parts and fuel system components.
6. Electrical & Cab
Older G700-series graders in particular generate high demand for electrical components — sensors, wiring harnesses, switches, and instrument cluster modules. Cab wear items including door glass, door seals, ROPS cab components, and seat assemblies are also regularly sourced. Browse electrical parts and cab and exterior parts.
Model-by-Model Parts Guide
Volvo G710 & G720 — Light Graders
The G710 and G720 are Volvo’s lighter motor graders, typically used in road maintenance, township work, and light earthworks. At 175–195 hp and around 15 tonnes, these machines accumulate high hours in continuous road grading duty. Circle gear wear and blade hydraulic cylinder seal failures are the most common issues. Parts for the G700 series (including VHP variants) are available across all major component systems at VMP Spares.
Top service items: Circle drive pinion gear, blade lift cylinder seals, air cleaner elements, fuel filter kits, tandem chain sets, articulation pin kits.

Volvo G730 & G740 — Mid-Range Graders
The G730 and G740 step up to 215–240 hp and are suited to highway maintenance, quarry road grading, and heavier earthworks. The G740 in particular is a popular machine in mining fleets where road quality directly impacts hauler productivity. At this power level, drivetrain component loads increase significantly — tandem drive chain and sprocket maintenance becomes critical.
Top service items: Tandem drive chain and sprocket kits, hydraulic pump rebuild kits, engine overhaul gasket sets, front axle lean cylinder seals, rear axle differential bearing kits, cab door seals.

Volvo G930 & G940 — Modern Light-to-Mid Graders
The G900 series represents a full redesign of the Volvo motor grader lineup, with improved electronic controls, better visibility, and updated hydraulic systems compared to the G700 series. The G930 and G940 occupy the light-to-mid segment and are increasingly common on large infrastructure projects. Parts for the B-series variants of these models are widely available.
Top service items: Hydraulic control valve seals, circle drive bearing kits, front wheel lean cylinder rebuild, engine injector sets, transmission filter kits, electrical sensor kits.

Volvo G960 & G990 — Heavy-Duty Graders
The G960 and G990 are Volvo’s heavy-duty motor graders. At 240–275 hp and over 19 tonnes, these machines handle the most demanding applications — mining haul road maintenance, airport runway grading, and large-scale highway construction. The G990 with its 6.1 m blade option is among the largest production motor graders available. At this scale, hydraulic system maintenance and tandem drive servicing are the highest-priority work scopes.
Top service items: Full hydraulic pump overhaul kits, tandem drive chain and sprocket complete sets, circle drive ring gear, blade pitch cylinder rebuild kits, engine turbocharger assemblies, rear axle oil seal kits.
